Examples of water pollution (hurry! ! ! ! ! ! ! ! ! ! ! ! )

What kind of example do you want? See China Environmental Bulletin for the overall situation. Let me give you some examples.

1. The Huaihe River water pollution incident shocked China and foreign countries. 1In July, 1994, the floodgates in the upper reaches of Huaihe River were opened for flood discharge due to sudden rainstorm, and 200 million cubic meters of accumulated water in the upper reaches of Huaihe River was put down. Where the water passes, the river is turbid, the foam on the river surface is dense, and the fish and shrimp suddenly lose. Residents in some places downstream have symptoms such as nausea, diarrhea and vomiting after drinking the river water treated with tap water but not up to the drinking standard. After sampling inspection, it was confirmed that the water quality of the upstream water deteriorated, and the waterworks along the Yangtze River were forced to stop water for 54 days, and millions of people in Huaihe River were in a hurry to drink water.

Two? In 2004, the "3.02" catastrophic water pollution accident in Tuojiang, Sichuan was named after four rivers in China. Rich water resources have created Sichuan, a land of abundance. However, from February to March, 2004, Tuojiang River, one of the four major rivers, brought an unprecedented ecological disaster to the land of abundance. At that time, due to a large amount of high-concentration industrial wastewater flowing into Tuojiang River, nearly one million people in five urban areas of Sichuan suddenly fell into the predicament of no water available, and the direct economic loss was as high as 2190,000 yuan.

Three? Beijiang River, a cadmium pollution accident in 2005, is one of the three tributaries of the Pearl River and an important drinking water source for cities in Guangdong. In June 5438+February 65438+May 2005, serious cadmium pollution occurred in Shaoguan section of Beijiang River, and the cadmium concentration in Gao Qiao section exceeded 12 times. Shaoguan is located in the upper reaches of Beijiang River. Once pollution occurs, it will directly affect the drinking water safety of tens of millions of people in downstream cities. Through investigation, it was found that the cadmium pollution accident in Shaoguan section of Beijiang River was caused by excessive discharge of cadmium-containing wastewater by Shaoguan Smelter during equipment maintenance, which was a serious environmental pollution accident caused by illegal and excessive discharge by enterprises.

In 2005, the Qihe River in Chongqing stopped supplying water because the water intake point was polluted. From June 5, 2005 to1October 3, 2005, nearly 30,000 residents in Daoqiaohe area of Gu 'nan Street in Qijiang, Chongqing had no running water for two consecutive days.

After investigation by the health and environmental protection departments, the river was polluted by the wastewater discharged by Chongqing Huaqiang Chemical Fertilizer Co., Ltd., and the relevant departments of Qijiang County immediately opened floodgates in the upper and lower reaches of He Qiao to speed up the dilution of polluted water, and instructed the sulfuric acid plant of Huaqiang Chemical Fertilizer Co., Ltd. to stop production and rectify. ?

Verb (abbreviation of verb) 2005 Songhua River major water pollution incident June 2005165438+1October 65438+March 3, an explosion accident occurred in the aniline workshop of Shuangbenzene Factory of China Petroleum Jilin Petrochemical Company. About 100 tons of organic pollutants such as benzene, aniline and nitrobenzene produced by the accident flowed into Songhua River. As a result, a major water pollution incident occurred in Songhua River. The Harbin Municipal Government immediately decided to close the water intake of the Songhua River in Harbin 165438 from 0: 00 on October 23rd, and stop supplying water to the urban area. The whole city of Harbin was cut off for four days, and all supermarkets in Harbin snapped up drinking water without exception.

In the circular issued on February 2, 65438, the General Office of the Central Committee and the General Office of the State Council stated that after the serious water pollution incident in Songhua River, the State Environmental Protection Administration, as the competent department of environmental protection, paid insufficient attention to the incident, underestimated the possible serious consequences and was responsible for the losses caused by the incident. Therefore, Xie Zhenhua applied to the CPC Central Committee and the State Council to resign as the director of the State Environmental Protection Administration, and this request was approved by the CPC Central Committee and the State Council. ?

Six? In February and March of 2006, a large number of fish died in Baiyangdian, the largest freshwater lake in North China, which is known as the "Pearl of North China".

The investigation results show that serious water pollution and low dissolved oxygen in water are the main reasons for fish suffocation. This incident caused 96,000 mu of water in Renqiu City to be completely polluted, and the water was black and smelly. All the fish cultured in cages died, a large number of dead wild fish floated in the lake, and some aquatic plants died black.

Seven? On September 8, 2006, a water pollution incident occurred in Xinqiang River, a drinking water source in Yueyang County, Hunan Province. Arsenic exceeds the standard by about 10 times, and the drinking water safety of 80 thousand residents is threatened and affected.

Finally, after verification, it was found that the pollution was caused by the daily discharge of industrial sewage from three chemical plants in the upper reaches of the river, which led to a large number of high-concentration arsenic-containing wastewater flowing into Xinqiang River.

The water pollution incident in Taihu Lake in 2007 began on May 29th, 2007. The tap water quality of a large number of citizens in Wuxi city, Jiangsu province suddenly changed, accompanied by unpleasant smell, which made it impossible to drink normally. The drinking water source of Wuxi citizens comes from Taihu Lake.

The reason for this sudden change in water quality is that since the summer, the water level in Taihu Lake in Wuxi City is the lowest in 50 years, and the weather continues to be hot and rainy, which leads to serious eutrophication of Taihu Lake, leading to the early outbreak of cyanobacteria and affecting the water quality of tap water sources. Wuxi citizens have rushed to buy pure water in supermarkets, and the price of bottled pure water in street retail has also fluctuated greatly.

Water Pollution in Shuyang, Jiangsu Province in 2007 At 3: 00 p.m. on July 2, 2007, the monitoring of the surface water plant in Shuyang County, Jiangsu Province found that the water intake of the waterworks located in Huaishuhe River was invaded by short-term and large-flow sewage, and the water source of urban domestic water supply was seriously polluted, and the water flow showed obvious odor.

After water quality testing, the ammonia nitrogen content in the water at the water intake is about 28 mg per liter, far exceeding the national water quality standard for water intake. Because the treated water quality can not meet the drinking water standard, the urban water supply system was forced to close, and the draft and water use of 200 thousand people in the urban area were affected to varying degrees. Until the morning of July 4, the water intake of the waterworks closed due to drinking water pollution was reopened, the normal water supply in Shuyang City was fully restored, and the water supply in Shuyang County was stopped for more than 40 hours.

Ten? Water Pollution Event in Yancheng, Jiangsu Province in 2009

On the morning of February 20, 2009, the raw water of Chengxi Waterworks in Yancheng City, Jiangsu Province was polluted by phenolic compounds, resulting in a large area of water shortage in the urban area. Due to water pollution, the drinking water of more than 200,000 residents in urban areas stopped for 66 hours and 40 minutes, causing huge losses.

Yancheng public security department has filed an investigation into the suspected major environmental pollution accident of Shibiao New Chemical Co., Ltd., and Hu Wenbiao, the legal representative of the company, and Ding, the production supervisor, have been criminally detained according to law. For the first time, China sentenced Hu Wenbiao and Ding 1 1 year and 6 years respectively for poisoning.

Previously, when China investigated the criminal responsibility of similar pollution incidents, it investigated the criminal suspects for the crime of pollution caused by major environmental accidents. Legal scholars believe that China courts have begun to investigate the criminal responsibility of those who pollute the environment with new charges, which are heavier and longer in prison, indicating that China has further intensified its efforts to crack down on serious environmental pollution incidents.
