Ganzhou developed aquaculture water body decontamination agent

"Lao Shui" and "Old Pond" are engaged in aquaculture, and many of them are affected by water pollution and even cause illness. Today, the problem that has plagued farmers for many years has been solved. Not long ago, the “Technology Study on Ammonia-nitrogen Degradation Culture Pond Ammonia Nitrogen and Nitrite Technology” carried out by the scientific and technical personnel of Quzhou City passed the expert appraisal organized by the Hebei Science and Technology Achievement Transformation Service Center.

China is a big country for aquaculture, but under the breeding mode that focuses on feeding, aquaculture water bodies are eutrophic, and ammonia nitrogen and nitrite are seriously exceeded. Traditional methods of chemical drug treatment will not only cause drug residues, cause pathogens to produce drug resistance, but also pollute the water environment, kill beneficial bacteria in the water, cause imbalances in the aquaculture ecological environment, lead to frequent occurrence of fish and shrimp disease and continuous decrease in yield. The utilization rate of “Old Water” and “Old Pool” that have caused years of decline has dropped and even become obsolete.

The project "Technology for Study on the Degradation of Ammonia Nitrogen and Nitrite in the Aquaculture Net of Yishuisu and Nitrosulfide" is an unscheduled science and technology project in Hebei Province and was included in the Ganzhou Municipal Science and Technology Plan, and was independently implemented by the Bozhou State Institute of Material Technology. Field trips and repeated experiments have finally led to the development of microbiological preparations capable of “eaten” pollution, i.e. water and nitrosozide, and 21.5 million mu of different water quality and cultured species in more than 20 provinces and cities including Yunnan and Shandong. Different types of ponds have been practically applied, and the test data have proved that the 72-hour degradation rate of ammonia nitrogen and nitrite by Yishuixin and nitrosamine reaches more than 98%.

Experts believe that this project has advanced technology, outstanding results, and strong practicality. The liquid-solid-state automatic fermentation technology and equipment created by the project is the first in China, and the overall level of the project ranks first in China.
