Analysis of the Effectiveness of the 'Three Pools and Two Dams' Model for Managing Aquaculture Wastewater in Different Pond Farming Areas
Abstract：Pond intensive farming is the main model of aquaculture in Chongqing. It plays an important role in providing high-quality animal protein, enhancing agricultural efficiency, and increasing farmers' income. However, pond farming wastewater contains organic matter such as leftover feed and feces, as well as pollutants such as nitrogen and phosphorus. If directly discharged into rivers, it can cause serious harm to the aquatic ecological environment. To address the problem of water pollution caused by direct discharge of aquaculture wastewater, Chongqing has issued the 'Aquaculture Wastewater Discharge Standard' (DB 50/1544-2023) to reduce the negative impact of wastewater on the environment. How to efficiently treat pond aquaculture wastewater and improve the farming environment, the authors implemented the 'Three Pools and Two Dams' model for managing aquaculture wastewater in concentrated pond farming areas in Kaizhou District and Yongchuan District of Chongqing, according to local conditions, and explored the effectiveness of this model under different scenarios, forming a replicable and scalable typical demonstration model.
