Tail water treatment and circulation system of shrimp aquaculture pond

Abstract

The invention discloses a tail water treatment and circulation system of a shrimp aquaculture pond. The tail water treatment and circulation system comprises an outdoor aquaculture water pretreatment system and an indoor aquaculture circulating water treatment system, wherein the outdoor aquaculture water pretreatment system is characterized in that tail water of the shrimp aquaculture pond is precipitated in a precipitation tank to remove solid waste; the precipitated water is subjected to aeration treatment for 2-3 hours; color-removing deodorant is added into the water after the aeration treatment; the color-removed and deodorized water is filtered through a filter screen to remove particle impurities with the particle size being larger than 100 micrometers and then enters the indoor aquaculture circulating water treatment system; the indoor aquaculture circulating water treatment system is characterized in that the filtered water is pumped into a water return pond; the water treated by the water return pond is pumped into a biological filter through a circulating pump; the water treated by the biological filter directly enters the shrimp aquaculture pond. The tail water treatment and circulation system saves water resources, reduces the waste of the water resources, improves the water utilization rate by more than 99%, reduces harmful substances in the treated water, and achieves green and harmless products.

Description

technical field [0001] The invention relates to a tail water treatment circulation system of a sea shrimp culture pond, which belongs to the technical field of water treatment. Background technique [0002] Since the last century, sea shrimp farming has become the fastest-growing species among marine animals in China. In recent years, the intensive and high-efficiency farming model has become an inevitable direction for the development of the sea shrimp industry, but the domestic sea shrimp industrialized recirculating aquaculture system is still in the initial stage of exploration, and a set of reliable sea shrimp circulation and high-efficiency aquaculture technology has not yet been formed. . Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a tail water treatment and circulation system for sea shrimp culture ponds to effectively utilize water resources. [0004] In order to s...
