A pond water body ectopic purification and recycling system

Abstract

The invention provides a pond water ectopic purification and recycling system, which comprises a culture pond, a sedimentation pond, an oxidation aeration pond, an ecological purification pond and a water storage pond which are sequentially connected in circulation, and a primary filter device is arranged between the cultivation pond and the sedimentation pond. The primary filtration device includes a purification tower, an upper filter cartridge, a lower filter cartridge, a water inlet pipeline, a drainage pipeline, a valve mechanism, a water barrier, a sealing ring and a lifting mechanism. The pond water ectopic purification and recycling system greatly reduces the content of nitrogen and phosphorus substances in the water body through ectopic purification of the water body in the aquaculture pond, reduces the discharge of aquaculture tail water, saves aquaculture water consumption, and improves the aquaculture environment. . The primary filter device can also clean up impurities while filtering, which improves the effective working time, realizes the preliminary filtration of the tail water, reduces the subsequent sedimentation time of the tail water in the sedimentation tank, and thus speeds up the treatment of the tail water. Purification treatment optimizes the efficiency of purification treatment.

Description

technical field [0001] The invention relates to the technical field of aquaculture water purification, in particular to a pond water body ectopic purification and recycling system. Background technique [0002] Pond aquaculture is the main aquaculture production method in my country. Due to the accumulation of aquatic excrement and the spoilage of residual bait caused by excessive feeding, the water quality of the aquaculture pond will continue to deteriorate, affecting the healthy growth of aquaculture objects, and a large amount of aquaculture pollution is discharged to The environmental impact has restricted the sustainable development of the pond aquaculture industry. [0003] At present, the regulation technology of pond aquaculture water treatment mainly adopts the methods of in-situ regulation and ex-situ treatment. The methods of in-situ regulation mainly include mechanical oxygenation, installation of biological floating beds, installation of biological brushes, etc...
