Factory ecological breeding circulating water circulation purification and recovery system and process

Abstract

The invention provides a circulating purification and recovery system and process for factory ecological breeding circulating water, an ecological breeding barrel is communicated with an element balance barrel, the element balance barrel is communicated with a nanometer microfilter, the nanometer microfilter is communicated with a four-stage biological fluidized bed purification degassing sterilization assembly, and the four-stage biological fluidized bed purification degassing sterilization assembly is communicated with a four-stage biological fluidized bed purification degassing sterilization assembly. The four-stage biological fluidized bed purification, degassing and disinfection assembly is communicated with the microorganism culture pond, the microorganism culture pond is communicated with the culture barrel, the pollution discharge end of the four-stage biological fluidized bed purification, degassing and disinfection assembly is communicated with an inlet of the biological dry-wet separation mechanism, and the pollution discharge end of the biological dry-wet separation mechanism is communicated with an inlet of the biological fertilizer pond; the biological dry-wet separation mechanism is communicated with the microorganism culture pond; solid impurities in aquaculture tail water such as fish and shrimp excreta and feed residues in the aquaculture barrel can be filtered and separated, purified water and bio-fertilizer are obtained through multiple filtering, purification and sterilization, the purified water can be used as aquaculture water again, the bio-fertilizer can be used for farmland fertilization, and waste water can be fully utilized.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a recycling system and process for industrialized ecological breeding circulating water circulation purification and recycling. Background technique [0002] Factory ecological farming is a new farming model, which can better achieve high-density farming. Compared with traditional farming methods, it is more profitable. In the factory farming of aquatic products, the water in the breeding tank needs to be changed frequently, which will cause It consumes a lot of water, and at the same time, the discharged waste water often contains fish and shrimp excrement, feed residue, etc., which cannot be fully utilized, resulting in a waste of resources. [0003] Therefore, there is an urgent need for a circulating water purification and recovery system and process for industrialized ecological aquaculture, which can solve the problems of large water consumption and insufficient utiliza...
