DesignIdeas for Separation of Inlet and Outlet Water and Tail Water Treatment in Continuous Aquaculture Ponds
Pond aquaculture plays a crucial role in China's aquaculture industry,ensuring the supply of high-quality animal protein,promoting agricultural efficiency,and increasing farmers'income.With the rapid develop-ment of the social economy,the traditional and extensive pond aquaculture model has highlighted a series of prob-lems,posing requirements and challenges for the improvement and upgrading of the industry.This paper takes a concentrated and contiguous 2050 acre aquaculture pond in Hubei Province as an example to sort out the design i-deas of inlet and outlet separation transformation and tail water treatment.Through the construction of new dit-ches and functional division,the inlet and outlet separation in the project area is achieved,which solves the pollu-tion of upstream tail water discharge on downstream pond water,reduces the risk of fish infection and disasters in aquaculture ponds.At the same time,ecological ditches and lotus pond wetlands are used as the main purification units.After treatment,the CODMn,total nitrogen,and total phosphorus indicators of the aquaculture wastewater steadily meet the second level standards of the Freshwater Pond Aquaculture Water Discharge Requirements(SC/T 9101-2007),greatly avoiding the impact of aquaculture wastewater on the water quality and water environment of the Han River.At the same time,this paper looks forward to the future design and construction direction of the separation of inlet and outlet water and tail water treatment of such ponds,and proposes a tail water treatment model suitable for the characteristics of aquaculture in Hubei Province,in order to provide new references for the design and construction of similar projects.
