Aquaculture tail water treatment system

Abstract

The invention provides an aquaculture tail water treatment system and aims to solve the technical problems that a great deal of tail water generated in conventional industrial aquaculture needs to betreated and discharged, and the like. The system comprises an aquaculture tail water collection pond, wherein the aquaculture tail water collection pond is connected with a submersible sewage pump; the submersible sewage pump is connected with a filtering bag; the filtering bag is connected with a water seepage pond; the water seepage pond is connected with a clean water well; the clean water wellis connected with a clean water storage pond; the clean water storage pond is connected with a first water pump; the first water pump is connected with a wetland treatment zone; the first water pumpis connected with an ultraviolet sterilization tank; the ultraviolet sterilization tank is connected with a water replenishing tank; the water replenishing tank is connected with an aquaculture system; the clean water storage pond is connected with a second water pump; the second water pump is connected with a sand filtering tank; the sand filtering tank is connected with an ozone purification device; the ozone purification device is connected with the clean water storage pond; a polymer water tank is connected with a first agent injection pump; the first agent injection pump is connected withthe filtering bag; a phosphoric acid removal agent tank is connected with a second agent injection pump; and the second agent injection pump is connected with the filtering bag. The aquaculture tailwater treatment system can be widely applied to the technical field of aquaculture.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aquaculture tail water treatment system. Background technique [0002] Aquaculture is an important part of agricultural production, plays an important role in the national economy, and has developed rapidly in the past fifty years. However, with the continuous expansion of the breeding scale, the accompanying problems such as frequent disease and low product quality have become increasingly prominent. Due to the occupation and consumption of a large amount of resources, ecological imbalance and environmental deterioration have been caused, coupled with the limitations of technology and resources. restrict its development. In this context, it is imperative for the aquaculture industry to develop into a factory. [0003] In the process of aquaculture industrialization, not only a large amount of toxic and harmful organic substances such as residual bait and excrement will ...

AI Technical Summary

Problems solved by technology

Although the pollution level of aquaculture tail water is far lower than that of industrial wastewater, it is very easy to cause water eutrophication, which will cause large-scale pollution to the external water environment and seriously damage the natural environment over time.
