Is setting off fireworks really a big environmental pollution?

Will setting off fireworks really pollute the environment? The raw material of firecrackers is sulfur. . Burning sulfur will produce sulfur dioxide. . Sulfur dioxide can cause acid rain. Then it causes damage to plants and crops. . . The consequences are very serious. . . If it's too much. . . Moreover, the fog generated during combustion also contains nitrogen, carbon, sulfur and a lot of dust, which is harmful to the lungs, blood and nerves if inhaled by the human body.

Is raising geese a big environmental pollution? According to the Regulation on Prevention and Control of Pollution in Livestock and Poultry Farming, which came into effect on 20 14 10, the State Council Decree No.643rd:

Thirty-seventh in violation of the provisions of this Ordinance, the construction of livestock and poultry farms and breeding communities in prohibited areas shall be ordered by the competent environmental protection department of the local people's government at or above the county level to stop the illegal behavior; Those who refuse to stop the illegal act shall be fined between 30,000 yuan and 654.38+10,000 yuan, and reported to the people's government at or above the county level for dismantling or closing. Construction of livestock and poultry farms and breeding communities in drinking water source protection areas shall be ordered by the competent environmental protection department of the local people's government at or above the county level to stop the illegal act, and a fine of 654.38+10,000 yuan but less than 500,000 yuan shall be imposed, and the person with the approval authority shall be ordered to dismantle or close it.

Does the aluminum art factory pollute the environment? It depends on what kind of products the medical device factory produces, because there are many kinds of medical devices, such as operating tables, injection products and other types. From the point of view of raw materials and processing, industrial production will cause certain pollution to the environment, but from the point of view of production technology, proper control will be better, and it is not impossible to realize green manufacturing.

Why do you still set off fireworks at apec meetings without polluting the environment? This is a noble and grand ceremony.

You can suggest,

Ke Zhuang Guowei, Zhuang Wei Jun,

A better way,

It is better to build and develop than to complain and grumble.

You're right,

There is no other good way for experts to teach senior engineers.

Do gas cars pollute the environment? Compared with fuel vehicles, gas vehicles have the following advantages:

1, stable combustion, no knock, convenient cold and hot start.

2. The storage, transportation, decompression and combustion of compressed natural gas are all carried out under strict sealing conditions, so it is not easy to leak. In addition, its gas cylinders are safe and reliable after various special destructive tests.

3. Compressed natural gas has the advantages of safe combustion, less carbon deposition, small gas resistance and knock, which is beneficial to prolong the service life of engine parts, reduce maintenance times and greatly reduce maintenance costs.

4. It can reduce the oil consumption.

Compared with gasoline, the use of compressed natural gas can greatly reduce the emissions of carbon monoxide, sulfur dioxide and carbon dioxide. And there are no carcinogenic toxic substances such as benzene and lead that endanger human health.

Is the use of firewood harmful to the environment? 1. It pollutes the air environment and harms human health. Some data show that when burning straw, three pollution indexes of sulfur dioxide, nitrogen dioxide and inhalable particulate matter in the atmosphere reach the peak, in which the concentration of sulfur dioxide is 1 times higher than usual, and the concentration of nitrogen dioxide and inhalable particulate matter is three times higher than usual, which is equivalent to the five-level daily average concentration. When the concentration of inhalable particles reaches a certain level, the mucous membrane in eyes, nose and throat is large, which can cause cough, chest tightness and tears, and even bronchitis in severe cases.

Hazard 2: Fire, threatening people's lives and property. Straw burning can easily ignite the surrounding flammable materials, especially near the village. Once a fire breaks out, the consequences are unimaginable.

Hazard 3: causing traffic accidents and affecting road traffic and aviation safety. The smoke produced by burning straw will reduce the visibility and visual range of the air and easily lead to traffic accidents.

Hazard 4: Destroy the soil structure, leading to the decline of cultivated land quality. Burning straw makes the ground temperature rise sharply, which can directly burn and scald beneficial microorganisms in the soil, affect the full absorption of soil nutrients by crops, directly affect the yield and quality of farmland crops and affect agricultural income.

Hazard 5: The smoke and scorched earth formed by burning straw is the biggest damage to the environmental image of a region.

Does phosphorus mud pollute the environment and crops? (1) Harm to human health: People need to breathe air to maintain their lives. An adult breathes about 20,000 times a day and inhales 15 ~ 20 cubic meters of air. Therefore, polluted air has a direct impact on human health.

The harm of air pollutants to human body is various, mainly manifested in respiratory diseases and physiological dysfunction, as well as the influence of * * on mucosal tissues such as eyes and nose.

For example, from February 5 to 8, the soot incident in London, England, killed 4,000 people. 1952+65438. People call the smoke of this disaster "killer smoke". According to the analysis, this is because there was no wind and fog in London, and the smoke generated by factory chimneys and residents' heating existed in London for a long time, with the highest smoke concentration of 4.46 mg/m3. The average daily concentration of sulfur dioxide reached 3.83 ml/m3. After a certain chemical reaction, sulfur dioxide produces sulfuric acid droplets attached to smoke or condensed on fog droplets, which enter organs with breathing, making people sick or accelerating the death of patients with chronic diseases.

As can be seen from the above example, when the concentration of pollutants in the atmosphere is high, it will cause acute pollution poisoning, or aggravate the symptoms, and even kill thousands of people within a few days. In fact, even if the concentration of pollutants in the atmosphere is not high, breathing this polluted air all the year round will cause chronic bronchitis, bronchial asthma, emphysema and lung cancer.

(2) Harm to plants: Air pollutants, especially sulfur dioxide and fluoride, are very harmful to plants. When the concentration of pollutants is high, it will cause acute damage to plants, damage to the surface of plant leaves, or directly cause leaves to wither and fall off; When the concentration of pollutants is not high, it will cause chronic damage to plants, make the leaves of plants turn green, or no harmful symptoms can be seen on the surface, but the physiological functions of plants are affected, leading to the decline of plant yield and deterioration of quality.

(3) Impact on weather and climate: The impact of air pollutants on weather and climate is very significant, which can be explained from the following aspects:

(1) Reduce the amount of solar radiation reaching the ground: A large number of smoke particles discharged into the atmosphere by factories, power stations, automobiles, household heating devices, etc. make the air very turbid, which blocks the sunlight and reduces the amount of solar radiation reaching the ground. According to observation and statistics, in the days when the smog does not disperse in large industrial cities, the direct sunlight on the ground is reduced by nearly 40% compared with the days without smog. In cities with serious air pollution, people, animals and plants are deprived of sunshine every day.

② Increase atmospheric precipitation: Many particles emitted by large industrial cities have the function of water vapor condensation nuclei. Therefore, when there are other precipitation conditions in the atmosphere, there will be precipitation weather. In the downwind areas of big industrial cities, there will be more precipitation. American Tmall Puwechat reminds us to take precautions when traveling in foggy days.

(3) Acid rain: Sometimes, the rain falling from the sky contains sulfuric acid. This kind of acid rain is formed by the oxidation of sulfur dioxide, a pollutant in the atmosphere, which decreases with the precipitation in nature. Acid rain will destroy large areas of forests and crops and corrode paper products, textiles and leather products. , make the metal antirust coating deteriorate, reduce the protective force, and corrode and pollute the building.

(4) Raise the atmospheric temperature: Over large industrial cities, the air temperature near the ground is higher than that in the surrounding suburbs due to a large amount of waste heat discharged into the air. This phenomenon is called "heat island effect" in meteorology.

⑤ Impact on global climate: In recent years, people have gradually noticed the impact of air pollution on global climate change. After research, people think that carbon dioxide plays an important role in various air pollutants that may cause climate change. About 50% of the carbon dioxide released into the atmosphere by countless chimneys and other exhaust pipes on the earth remains in the atmosphere. Carbon dioxide can absorb long-wave radiation on the ground. It is called "greenhouse effect" to increase the air temperature near the ground. According to a rough estimate, if the carbon dioxide content in the atmosphere increases by 25%, the temperature near the ground will increase by 0.2℃. If 100% is increased, the near-surface temperature can be increased by 1.6℃. Some experts believe that if the carbon dioxide content in the atmosphere increases at the current rate, the ice in the polar regions will melt in a few years.

Is the leather factory very polluting to the environment? What is the main source of pollution? Thank you. Leather factories have a great impact on the environment, mainly from the following aspects:

1. Tanning production generally includes: preparation section, tanning section and finishing section;

2. Production technology:

The rawhide is finished by washing, soaking, unhairing, liming, removing meat, cleaning, washing, softening, washing, pickling, chrome tanning, cutting evenly, neutralizing, dyeing, oiling and finishing.

Pollution sources and pollution factors:

Tannery wastewater (COD, BOD5, SS, sulfide, chloride ion, trivalent chromium, phenol, PH, chromaticity, animal and vegetable oil, etc. )

Air pollution (TSP, PM 10, SO2, NOX, NH3, H2S, odor, etc. )

Solid waste (waste wool, meat film, broken skin, scraps, leather scraps, sewage station sludge, boiler slag)

Noise (equipment noise)

In addition to boiler flue gas, tannery waste gas also includes volatile organic solvents used in production and malodorous pollutants generated in storage, production and sewage stations of hides.

The main sources of wastewater: during the production and processing of hides, a large amount of protein and fat enter into wastewater and waste residue; A large number of chemical raw materials are used, such as acid, alkali, salt, sodium sulfide, lime, chrome tanning agent, dye, etc. , has entered the waste water. Tanning wastewater mainly comes from preparation, tanning and wet processing sections, in which the wastewater discharge and pollution load of preparation section before tanning account for 70% of the total tanning wastewater; Tanning stage and wet processing stage account for about 8% and 20% of wastewater respectively;

Tannery wastewater has strong alkalinity and deep chroma, and contains inorganic substances such as protein, fat, dye, chromium, sulfide and chloride, which belongs to toxic and harmful wastewater. Among them, the chromium removal process and the sulfide in the waste liquid of lime-alkali hair removal are seriously exceeding the standard, which is the focus of wastewater treatment in leather industry.

Will the fireworks industry decline in the face of environmental pollution? Xinhuanet Beijing, February 6th, New Media Specialist (Reporter Qin Juji, Liu Shuo, Zhang Man Zi) With the introduction of regulations prohibiting and restricting the discharge of fireworks and firecrackers in more and more regions, and a series of anti-corruption measures in recent years prohibiting public funds from buying and giving fireworks and firecrackers, the traditional fireworks and firecrackers industry is facing unprecedented pressure, and the market is gradually shrinking.

The reporter interviewed some fireworks manufacturers and distributors and found that the severe market situation has made many manufacturers and distributors complain bitterly. Some small enterprises simply seek to change careers, while large enterprises with a certain scale seek product transformation and upgrading in an attempt to save the decline.

Encounter a "severe winter" under the ban and restrictions.

The 23rd of the twelfth lunar month is the date of setting off fireworks and firecrackers in Changchun in previous years. Many dealers often start stocking up a week in advance, but there are no fireworks and firecrackers distribution booths in the main city of Changchun this year. August 20 14, with the promulgation of "Regulations on Safety Management of Fireworks and Firecrackers in Changchun City", the sale and discharge of fireworks and firecrackers were prohibited in the area within the Fourth Ring Road of Changchun City throughout the year.

The reporter visited some fireworks storage, transportation and dealers before, and found that the lively wholesale scene a few years ago has been hard to see in the past two years, and the average daily sales volume has declined year after year. Some fireworks wholesale enterprises have less than half of their customers, most of whom are small and medium-sized retail investors. In order to save the market, dealers have to greatly reduce their profit margins and have a "big sale".

According to the sales staff of Panda Fireworks, due to the shorter sales time of fireworks and firecrackers in the Spring Festival of the Year of the Sheep than in previous years, the stocking volume has decreased this year. At present, the total stocking volume is 1.5 million cases, and the order volume of merchants has decreased by 20% compared with the same period of last year.

Mr. Wang, the sales manager of a large fireworks sales enterprise in Jilin Province, told reporters that the current market situation is "winter" for them. He told reporters that the previous year's sales could still be several million yuan, but it has been declining in recent years, and this year is only about half of last year's. The company's current inventory is enough to sell for several years, and a lot of money has been put into the goods. If the market continues to deteriorate, we can only consider doing something else.

20 14 12.30, Weibo @ Nanchang, the government affairs hall of Nanchang * * * Information Office, released a message saying: "Recently, there have been frequent haze weather in various places. In order to reduce pollutant emissions and maintain good air quality in Nanchang, the fireworks display in Jiang Xinzhou of Ganjiang River scheduled for 12, 3 1 night was cancelled. " Hou, deputy general manager of Jiangxi Lidu Fireworks Group Co., Ltd. said that after the introduction of the eight central regulations, many large-scale fireworks display activities were cancelled in the past two years, which was a loss for the company. For some small and medium-sized manufacturers who produce ordinary public products, life is getting more and more sad because of the sharp decline in market purchasing power.

Can environmental protection fireworks save the decline?

The reporter learned that due to the "accusation" of polluting the environment and creating smog, many fireworks and firecrackers manufacturers have turned to the research and development and production of environmentally friendly fireworks and firecrackers. Hou told reporters that at present, 70% to 80% of the products produced by Lido Group belong to environmental protection products, which can effectively reduce environmental pollution.

The reporter learned that environmental protection fireworks will have more beautiful colors and less smoke. At present, it mainly exists in combination fireworks, thread incense and children's fireworks. The person in charge of panda fireworks sales said that the environmentally-friendly fireworks developed by the company on 20 14 adopted sulfur-free emission technology, the fireworks did not contain sulfur, and the combustion gas did not contain sulfur dioxide. Reduce the cost by 6%, reduce pollution and reduce costs. This kind of environmentally friendly fireworks accounts for 70% of the total inventory of fireworks and firecrackers this year.

A person in charge of a fireworks sales enterprise in Jilin Province told reporters that the company is actively preparing to sell environmentally-friendly fireworks and firecrackers. "There will be a large number of listings starting next year. Now many manufacturers in Jiangxi and Hunan are producing, and the supply will gradually increase. " A person in charge said.

For the public, it is a question whether the price of environmental protection fireworks will be too high. In this regard, the heads of some fireworks production enterprises said that they are now in the initial stage of research and development and market of environmentally friendly fireworks, and the research and development costs are relatively high, and the market price will be higher than that of traditional products. However, with the mass production of products, prices will fall, and some enterprises actively sacrifice profits to reduce prices in order to seize the market.

Guiding transformation is the "king"

In recent years, due to the frequent accidents in the fireworks industry and the "severe winter", the management department has strictly rectified the production enterprises and tried to guide the market development by reducing the production scale. After many rectifications, the number of fireworks and firecrackers production enterprises in Jiangxi Province will drop from more than 2,000 in 20 13 years to more than 20 1000 by the end of 20 15. According to the reporter's understanding, fireworks production and sales enterprises in many places have also experienced the process of "shuffling" in the past two years.

Chen Jian, a member of the Jiangxi Provincial Political Consultative Conference, said that it may not be a long-term solution for fireworks and firecrackers to shut down and limit production. He believes that while shutting down some unqualified fireworks and firecrackers enterprises, * * * should strive to take various measures to support enterprises to transform production and guide the healthy development of the industry; At the same time, we should also support some large enterprises, strengthen investment in research and development of environmental protection products, and cultivate the consumer market of new products.

Rao Hui, chief engineer of Nanchang Environmental Monitoring Station, believes that from the perspective of protecting the environment and establishing fresh air, guiding citizens to choose environmentally-friendly products with no pollution and low energy consumption can not only reduce the environmental pressure, but also make the annual flavor more abundant, killing two birds with one stone.
