Multi-stage precipitation and filtration aquaculture tail water treatment system

Abstract

The invention belongs to the technical field of water treatment, and provides a multi-stage precipitation and filtration aquaculture tail water treatment system which comprises a biological brush aeration tank, a placement frame and a biological brush taking and placing device, wherein the placement frame comprises a plurality of horizontally-arranged and mutually-parallel cross beams, a plurality of hanging rods used for hanging biological brushes are arranged between every two adjacent cross beams at intervals, the two ends of the hanging rod are each provided with a chuck, and the biological brush taking and placing device comprises a grabbing device used for grabbing the chucks, a lifting device used for driving the grabbing device to do lifting motion, a transverse moving device used for driving the lifting device to move in the horizontal plane in the direction parallel to the cross beam, and a longitudinal moving device used for driving the lifting device to move in the horizontal plane in the direction perpendicular to the cross beam. According to the invention, the biological brush taking and placing operation convenience is improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a multi-stage sedimentation filtration 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 s...

AI Technical Summary

Problems solved by technology

At present, the operation of placing the hanging rod with the biological brush on the steel frame and removing it from the steel frame is performed by workers entering the biological brush aeration tank to complete the relevant operations. On the one hand, the operation is inconvenient. On the other hand, the labor intensity of workers is high
