The tail water can also be clear!Suzhou fishery "green transformation" has a wonderful trick

The ecological transformation of the farming pond, the adopting ecological health breeding methods, and the long -term maintenance management ... a series of measures allow the pond farming to meet the standards of the tailwater, and promote the high -quality development of Suzhou fishery.

Jiangsu's "Pond Breeding Tail Water Emissions Standards" has been officially implemented from August 1 last year, and it has been one year so far. Over the past year, Suzhou has continued to focus on the construction of ecological fisheries, and has promoted the results of the discharge of the tailwater standards. By the end of this year, the city's 306,600 acres of breeding ponds will achieve full coverage of high -standard farming ponds.

Entering the Modern Fishery Industrial Park in Linhu Town, Wuzhong District, I saw that the pond water farming base of the flowing sink was clear, and the sea bass and white fish swim in the water. This is the "fish and vegetable symbiosis" ecological health breeding. To "Fat Water Do not flow outsiders fields."

"The fish manure and impurities generated during the fish farming process are regularly collected through the pipeline to collect the sedimentation of the dirty barrel. The solid fertilizer is regularly transported to make organic fertilizer, and the liquid fertilizer is transported to the vegetable greenhouse through the pipeline. Later, the clean water flowed to the crab pond again, which formed a circular and promoted cycle mode. "Zhang Xuehong, deputy general manager of Suzhou Taihu Modern Agricultural Development Co., Ltd., introduced.

Beside the fish farming base, there is a lot of lotus leaves. These clean pond water is purified by the "four ponds and three dams".

The "Four Ponds and Three Dams" consist of the sedimentation tank, microbial purification tank, artificial submarine wetland purification tank, ecological pool and overflow dam, and submarine dam. Among them, the microbial purification pool adsorbed, decomposed, and purified the tail water that was attached to the net brush to the tail water from the sedimentation tank. The microbial purification pool also has both the aeration tank.

"After the crab manure and feed residue are fermented, there will be a lot of ammonia nitrogen elements in the farming tail water. Now, through the ecological transformation of the pond and the healthy and scientific breeding methods, pollutants are greatly reduced, and pond water is cleaner." Breeding is breeding. " The household Chen Jianqing contracted 100 acres of pond farming hairy crabs, and the feed feed now changed from ice fish to feed and corn. He also invested snails in the pool to purify the pool water to reduce pollutants.

At the same time, the park is also equipped with an automatic online monitoring system for breeding tailwater to ensure the discharge and recycling of the standard of farming tail water.

Gu Xuelin, an engineer at the Agricultural and Rural Bureau of the Agricultural and Rural Bureau of Wuzhong District, introduced that five monitoring points were arranged from farming pond water and tail water purification water to water source water. It was monitored in June in the whole year that it was monitored in December, and the entire district was monitored at the end of December. A suggestion of long -term management and protection is issued, and then sent to various villages to refer to rectification.

Modern Fishery Industrial Park, Linhu Town, Wuzhong District, is only a vivid epitome of the high -quality development of Suzhou fishery. In the past year, Jiangsu ’s“ Pond Breeding Tail Water Emissions Standards ”has focused on the construction of ecological fisheries in Suzhou and continued to promote the discharge of farming tailwater through the“ four one ”work measures.

Release a "implementation opinion". Suzhou recently released the "Implementation Opinions on Accelerating the High -quality Development of Fishery", which requires comprehensively promoting the standardization and transformation of ponds and promoting the discharge of tailwater standards. The pond farming area of ​​the city of Suzhou was 306,600 mu, and the reconstruction area of ​​high standard ponds was 295,800 mu, and the coverage rate of high standard ponds was 96.46%. At the end of this year, we will strive to achieve a full coverage of high -standard transformation in the province.

Prepare a set of "technical measures". Focusing on the discharge of the tail water standard, the "five major actions" of the promotion of aquatic green health breeding technology is implemented, and 10 "ecological breeding technical specifications" of aquatic varieties are compiled, 13 ecological breeding models are integrated Emissions, high -quality shrimp and crab special industries, promote the development of aquaculture to environmental friendly, reduced income increase, and improve quality and efficiency.

Print a set of "management and protection methods". On the basis of the "Administrative Measures for the Long -Effects of Standardized Ponds" in Suzhou City, guidance has been issued one after another according to local conditions, the three -level management and control network of district and towns (street) villages is established to implement special personnel maintenance management and ensure the normal operation of tailwater treatment facilities. Wide publicity, create a good social public opinion atmosphere that promotes the discharge of tail water discharge of ponds.

Formulate a set of "monitoring schemes". The city of Suzhou has 95 water quality monitoring points to carry out daily monitoring of breeding tailwater. At the same time, this year the city's 35 key agricultural parks -related agricultural parks are included in the scope of the annual tailwater discharge monitoring. ; In the park, it is supported by the construction of an automatic online monitoring system for farming tailwater to monitor real -time monitoring to ensure the discharge or recycling of farming tail water.

Xu Yan, deputy director of Suzhou Aquatic Products Technology Promotion Station, introduced that by the end of this year, the city's 306,600 mu of breeding ponds will achieve full coverage of high -standard breeding ponds, and the long -term management and protection of the cultivation area of ​​farming water. On the basis of ensuring the benefits of breeding, we must improve the quality of aquatic products and pay more attention to the ecological environment of the aquaculture waters.
