Share successful cases of using "activated carbon"

Case 1: Treating white water turbidity with "Good Morning Health"

There is a 40-mu crab pond in Tuanjiewei, Gaochun City, Jiangsu Province, where the density of captive crabs (local seedlings) is 700/mu, and the green shrimp seedlings 1 1 kg/mu. The purse seine in Bantian is mainly planted with Elodea and Lycopodium, which grow well and the water level is 30 ~ 40 cm. The ditch is 5 ~ 6 meters wide, Elodea nuttallii grows well on both sides of the ditch, and the water level in the ditch is 1 ~ 1.2 meters. In the early stage, vegetable cake, compound fertilizer and pig manure were the main fertilizers. Last year, some snails remained at the bottom of the pond. At the beginning of this year, two cars of snails were put into the ditch, about 1. 1 ten thousand Jin.

After the rain on May 8, the pond was turbid, the water was white, and the transparency was insufficient 10 cm. This situation has not improved for seven days.

15 May, at 2: 00 pm, the technical service personnel of Liyang Pharmacy tested the water quality (bottom water), and the pH value was 8.0, ammonia nitrogen was 0.25mg/L, nitrite was 0. 12mg/L, and dissolved oxygen was 4.0mg/L. 14 night, there were.

May 16, sunny, morning 10 cm or so water (exogenous water is better). Use 3 barrels of "activated carbon" and "algae ansheng" in the morning.

May 18, sunny. In the morning, the color of water is yellow-green, the phenomenon of white water disappears, and the phenomenon of muddy water is obviously improved, with a transparency of about 40 cm.

May 19, it rained.

It was cloudy in the morning of May 20, and I went to Tangkou at 9 o'clock to observe that the water color was basically the same as that on 18, and there was no "water bloom" phenomenon.

Situation 2: It is difficult to fertilize after the treated water is removed.

Penaeus vannamei is cultured in Gaotang (cement slope protection+membrane bottom) in Danchangyuan Village, Sigeng Town, Dongfang City, Hainan Province, with an area of 2.5 mu. 13 In the afternoon of February, 650,000 shrimps and four 1.5kW water wheel aerators were put into operation, with an average water depth of 1.3 m (beside 1 m).

March 3-4, cloudy.

March 5, cloudy. At noon, I found that the water in the pond was "clear" and faintly bottomed out. Then I detoxified and put 5 Jin of amino acid fertilizer, but the water still didn't improve.

March 6-7, sunny. After adding 5 kg of amino acid fertilizer, diatom mud and live bacteria king, there is still no improvement.

March 8, sunny. According to the test of Shangliyang pharmacy, the pH value is 8.2, and there is no ammonia nitrogen and nitrite, only a very small amount of green algae. After returning, the customer injected about 3 cm of fresh water, and then made 1 bottle of "activated carbon" +2 packages of "tricyclic active source (fertilizer water type)". After 1 hour, the water quality improved and the transparency reached 50 cm in the afternoon.

March 9, sunny. After using 1 bottle of "activated carbon" and 2 packs of "tricyclic active source (fat water type)", the transparency dropped to 35 cm in the afternoon.

1 is used in combination with "Liyunduo Ⅱ", and the water conservation effect is outstanding.

There is a 7-mu soil pond in Bailing Village, Dongli Town, Leizhou City, Zhanjiang City, Guangdong Province, with a water depth of 1.2 m, where Penaeus vannamei is cultured. Seedlings were released in April 13, because it is a earthen pond that has been cultivated for many years, and the bottom of the pond is rich in organic matter and fertile, and the transparency is about 50 cm from the beginning. On April/0/5, KLOC used "activated carbon"+"Zao An Sheng"+"Lijunduo Ⅱ" to fertilize the water, and the water became thicker, with a pH of 8.6 in the morning and a transparency of about 30 cm. In May, the temperature rose, algae grew vigorously, many ponds were filled with water, and shrimp ate slowly. However, due to the long-term adherence to the use of "activated carbon" and "Lijun Duo No.2", the water quality of this pond has been very refreshing, and the transparency has been maintained at around 30 cm. Shrimp has been eaten very well, and the effect of water retention and stability is outstanding.

2. Cooperate with "Lijun Duo II" to stabilize the pH value.

A high pond (cement slope protection+membrane bottom) for cultivating Penaeus vannamei on the continental slope of Sigeng Town, Dongfang City, Hainan Province, covering an area of 3.2 mu. On the afternoon of March 18, 700,000 seedlings were released, and 1.5kW+2 0.75kW water wheel aerators (fully opened in the daytime and 4 in the evening) were used, with an average water depth of 1.4 m (pool edge 1. 1 m).

Fat water in the morning of March 16.

March 18 Go to the store to measure water at noon. The results are as follows: under the microscope, the algae phase is mainly diatom, with pH 9.2 and no ammonia nitrogen and nitrite. On the same day, 1 bottle of "activated carbon" and 3 bottles of "Lijun Duo II" were used.

On the morning of March 19, it was used again according to the method of the previous day, and the pH value dropped to 8.7 at noon.

3. Cooperate with "Carp Duo Ⅱ" to restore the pond water color.

Case 1: A shrimp pond in Qinzhou, Guangxi, released its seedlings on March 26th.

On April 24, the water was turbid and there were many dead algae bubbles.

On April 25th, I used a bottle of "activated carbon" and a bottle of "Lijunduo II".

Use it again on April 26th.

On April 27th, all the dead algae bubbles disappeared, and the water quality was much fresher.

Case 2: A high pond (cement slope protection+membrane bottom) for cultivating Penaeus vannamei in Danchangyuan Village, Sigeng Town, Dongfang City, Hainan Province, with an area of 3.2 mu. On the afternoon of April 3rd, 700,000 seedlings were released, and 6 1.5kW waterwheel aerators were installed, with an average water depth of 1.4m (pool edge 1.2m).

On April 4th, I shot a bottle of EM bacteria and photosynthetic bacteria respectively, and I haven't made up for it since.

April 9, sunny. At noon, many dead algae bubbles were found on the water.

April 10, sunny. In the morning, use 1 bottle of "activated carbon" +2 bottles of "Lijunduo II". At noon, the foam of dead algae on the water surface decreased obviously.

1, treatment of cyanobacteria water

Case 1: Penaeus vannamei pond in Qinzhou, Guangxi, with an area of 6 mu and an average water depth of 1.2 m. After the seedlings were released in 14 days, there were many obvious cyanobacteria floating on the surface of the water body in downward flow, and a large number of Microcystis could be seen under the microscope, and the pH value was 10. 1.

Use 1 bottle of "activated carbon" and 2 bottles of "Lijunduo II" for 2 consecutive days.

Three days later, a yellow oil film appeared in the downward flow of the pond. Microscopic examination showed that Microcystis was obviously reduced, accompanied by cracked dead algae, and the pH value dropped to 8.6, reminding customers to pay attention to detoxification.

After four days, the color of the water body improved obviously.

Case 2: There is a pond in Shabian Village, Haiyan Town, Taishan City, Guangdong Province, with a mixed culture mode of fish and shrimp, with an area of 7 mu and a water depth of about 1m, equipped with three impeller aerators (1.5 kW/ set), and 300,000 hybrid larvae of Penaeus vannamei were released on July 28, 2005.

On August 25th, the feeding of prawns was a little slow. It is found that the water color is blue-green, the transparency is about 10 cm, and cyanobacteria blooms have appeared in downward flow. The water quality test results show that there is no ammonia nitrogen and nitrite, and the pH value in the morning is 9.0. At noon, 1 bottle of "activated carbon" and 2 bottles of "Lijun Duo II" spilled out.

On August 27th, we used 1 bottle of "activated carbon" and 2 bottles of "Lijunduo Ⅱ" again.

On August 28, the number of cyanobacteria decreased, the water color improved slightly, and the feeding situation did not improve.

I ate a little faster on August 29th, and used 1 bottle of "activated carbon" and 2 bottles of "Lijunduo No.2".

On August 3 1 day, cyanobacteria were no longer visible on the water surface, and the water color was much fresher. The feeding of prawns returned to normal, and the pH value was 8.6 in the morning.

2. Treatment of Chlorella water

Case 1:20 15 On March 25th, a membrane pond with rhinoceros feet covering an area of 3 mu in Qinzhou City, Guangxi, was used for stocking Penaeus vannamei larvae. After 10 days, the water turned yellow and the water quality was not refreshing. Chlorella was mainly examined under the microscope. On April 6th and 7th, we used "Activated Carbon+Lijunduo Ⅱ" twice, 3 mu/ per group. On April 8, the water color gradually turned green, and green algae dominated under the microscope.

1, supplement the nutrition of aquatic plants and enhance the vitality of aquatic plants.

Case 1: There is a crab pond in the south of Heqiao, Yixing City, Jiangsu Province, with an area of 40 mu. Since the beginning of June last year, aquatic plants have been supplemented with "activated carbon" every 10 day. After using it twice, I obviously felt that the stems of the grass were thicker than before, and the leaves of the grass were green and fresh, full of vitality. Grass floats about half a month later than most people, only in some areas, and there are many white roots in the grass. Boss Zhu was very satisfied and used it regularly until the end of August, which provided a guarantee for the last two molts of the river crab.

2, high temperature weather, floating grass to keep fresh

Case 1: The water depth of the purse seine in Tonggushan, Taihu Lake, Jiangsu Province (more than 2.5m). Every year, aquatic plants are difficult to grow or start floating early, and floating grass is easy to sink and rot in high temperature weather. In late June of 20 14, after the aquatic plants in a crab pond floated up, they sprinkled "activated carbon" on the floating plants. After use, it was found that the color of aquatic plants turned green, so it continued to be sprayed several times in small quantities, and the speed of sinking and rotting of aquatic plants was obviously slowed down. At this time, the aquatic plants in other nearby ponds are seriously rotted.

3. Cooperate with "multi-bacteria" to divert water and protect grass.

Case 1: There is a 7-mu pond in Xinjian Town, Yixing City, Jiangsu Province. On 20 1900, 65438 crabs were released per mu, and Elodea was planted, with an average water depth of 50 ~ 70 cm.

On June 2, it was observed that the water was white and turbid, and a large amount of organic matter was hung on the leaves of aquatic plants. After being fished out of the water, the part hung with organic matter fell off, and the aquatic plants in serious areas began to grow moss (Cladosporium), and the aquatic plants were weak and had fewer white roots.

On June 3rd, the weather was fine, so it was suggested to use bleaching powder to control the proliferation of moss, and the dosage was 2kg/mu.

On June 4th, a sunny day, we used 1 bottle of "activated carbon" and 2 bottles of "+Lijunduo Ⅱ" to divert water and protect grass.

On June 5, it was cloudy and the water color began to clear up.

From June 6 to 7, it turned cloudy to light rain.

On June 8, the aquatic plants improved obviously, the dirt hanging on the grass decreased obviously, buds began to grow, and the water color turned clear.

On June 12, the aquatic plants returned to normal, basically not dirty, the buds grew well, the new white roots increased obviously, and the water color was slightly white with light green.

Case 2: A crab culture pond in Zhaishu Village, Rulin Town, Jintan District, Changzhou City, Jiangsu Province, with an area of 3 mu and stocking density of 1.600/ mu. Elodea nuttallii is planted in the whole pond, and the water depth is 60 ~ 65,438+000 cm. It is equipped with a water jet aerator.

20 13,12 On June 2nd, Elodea was found to be in poor growth and pale water color. At 10 in the morning, half a bottle of "activated carbon" and "Lijunduo II" were used, and the aerator was turned on for 3 hours.

On June 16, I went to the pond to observe that the aquatic plants are growing well, the water quality is refreshing, and there are many white roots in the aquatic plants.

4. Cooperate with "more bacteria" to promote the growth of aquatic plants.

Case 1: There is a 13 mu crab pond in Tunwan Village, dongshan town, Wuzhong District, Suzhou City, Jiangsu Province, with an average water depth of 70cm. A new species of Elodea nuttallii 20 14. At the beginning of April, a large number of "herbivores" appeared, and the aquatic plants grew slowly and turned black. On April 29, I went to Tangkou to serve food, and found that most of the grass leaves were eaten up. The water plants were hard and rough, and there were no buds, so "eating grass insects" decreased. The water quality test found that nitrite was 0. 1.5mg/L, ammonia nitrogen was 0.5mg/L, and the water quality index exceeded the standard.

On April 30th, I used two bottles of "activated carbon" and two bottles of "Lijunduo II".

On May 6th, the water plants sprouted buds and white roots. The water quality test results show that nitrite is 0.05mg/L and ammonia nitrogen is 0.1mg/L. ..
