Purification device for aquaculture tail water

Abstract

The invention provides a purification device for aquaculture tail water. The purification device comprises foam float pieces, steel pipes and a nylon net, wherein the foam float pieces are tied to thesteel pipes, and a square is defined by the four steel pipes tied with the foam float pieces floats on the water surface; the nylon net extends upwards out of the water surface and goes deep downwards into the water, and the parts, extending upwards out of the water surface, of the nylon net are tied to the steel pipes through ropes; a floating plant control-culture fence is defined by the square, defined by the four steel pipes tied with the foam float pieces, and the nylon net tied to the steel pipes; the lower end of the nylon net is weighed down by a stone cage filled with stone. The purification device for the aquaculture tail water can realize purification of the aquaculture tail water, occupies little space and is low in cost, simple to maintain and high in purification efficiency.

Description

technical field [0001] The invention relates to the field of environmental protection water body purification, in particular to an aquaculture tail water purification device. Background technique [0002] Pond aquaculture is the most important part of freshwater aquaculture in China, about 71.2% of the production comes from pond aquaculture; aquaculture production accounts for 71% of the world's total aquaculture production and 74% of the country's total aquatic production. Affected by congenital factors such as lack of water resources and land area, poor breeding infrastructure, heavy environmental pollution, and declining productivity, especially with the rapid development of intensive aquaculture models, the deterioration of water quality and wastewater discharge have directly restricted the aquaculture industry. of sustainable development. During the breeding process, the discharge of bait, the decomposition of residual bait, the production of excrement, and the use of ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art of aquaculture tail water purification treatment, the discharged aquaculture tail water needs to be settled and purified in each pond first; the aquaculture tail water purification pond accounts for 5%-10% of the entire aquaculture pond area, occupying aquaculture land, and building the pond requires manpower More material resources and higher cost; each pool needs to be maintained and cleaned every once in a while, which also requires manpower and material resources, which increases the cost of purification; and each pool needs to stay for a period of time to purify the tail water, which takes a long time to purify. low efficiency
