Purification tank for sewage in breeding industry

Abstract

The invention discloses a purification tank for sewage in breeding industry. The purification tank comprises a sewage tank, at least one grid plate arranged in the sewage tank, and a plurality of light source parts arranged on one side of the grid plate; the purification tank is characterized in that the grid plate is vertically arranged in the sewage tank, when a plurality of grid plates are arranged, the plurality of grid plates are distributed at intervals, at least one reaction zone is arranged on one side of the grid plate along the longitude and latitude directions, and any two reactionzones are distributed in a crossed manner; and at least part of light sources emitted by the light source parts can illuminate on the reaction zones, the surfaces of the reaction zones form an overlapregion with the light sources and a catalysant, and a photocatalytic reaction can be performed in the overlap region.

Description

technical field [0001] The invention relates to a purification pond, in particular to a breeding sewage purification pond. Background technique [0002] With the increasingly tense water resources, sewage treatment, purification and reuse have become an indispensable and important development direction in economic and social development. Farm sewage mainly includes urine, some feces and flushing water, and the content of suspended solids and ammonia nitrogen is large. After a kind of untreated sewage enters the natural water body, it will increase the content of suspended solids, organic matter and microorganisms in the water, change the physical, chemical and biological community composition of the water body, and deteriorate the water quality. [0003] In order to achieve the organic combination of economic benefits, social benefits and environmental benefits, the sewage must be effectively treated. With the rapid development of the livestock and poultry breeding industry,...

AI Technical Summary

Problems solved by technology

[0003] In order to achieve the organic combination of economic benefits, social benefits and environmental benefits, the sewage must be effectively treated. With the rapid development of the livestock and poultry breeding industry, the pollution of farm sewage is becoming more and more serious. Due to the variety of farm sewage , the composition is complex, the treatment is difficult, the existing sewage treatment equipment is huge, the structure is complex, the treatment cost is high, and some existing small sewage treatment equipment has the problems of poor effect and poor effluent quality
