A split solid waste separation culture pond

Abstract

The invention relates to a branched solid waste separation culture pond. The branched solid waste separation culture pond is characterized in that a culture pond excrement separator is composed of an upper way and a lower way for sewage discharge, a sewage discharge vertical pipe is connected with a transverse pipe, and a culture pond upper portion sewage discharge channel is formed; a bottom sewage discharge chamber is connected with the transverse pipe, and a culture pond lower portion sewage discharge channel is formed; a branched sewage discharge pipeline can increase suction force of the sewage discharge pipe and can also avoid the phenomenon that excrement floating on the upper layer of the water surface continues to float in the sewage discharge vertical pipe; meanwhile, a vertical pipe sleeve can be rotated to adjust the position according to the height of water and surface excrement distribution phenomenon in the actual culture process so that the height of a sewage draining exit can be proper, and the best excrement and foam separation effect is achieved. The branched solid waste separation culture pond is simple and novel in structure, can effectively discharge residual feed excrement inside the culture pond, and effectively solves the problem that the aquatic water is degraded due to the fact that ammonia nitrogen accumulation and harmful germ breeding are caused by residual feed excrement deposition.

Description

technical field [0001] The invention relates to a culture pond in aquaculture, and more specifically relates to a culture pond which can separate solid waste by way. Background technique [0002] As a big aquaculture country, my country ranks first in the world in terms of total aquaculture products. According to the survey of the China Fishery Statistical Yearbook, the total amount of aquatic product farming in my country reached 49.379 million tons in 2015, accounting for about 73.70% of the total domestic aquatic product production. But at present, water resources have become the most important resource for survival and competition in the world. The rapid development of aquaculture industry has brought heavy pressure on China's water resources. At the same time, with the increasing scarcity of land resources and environmental pollution, The pressure of high-efficiency and environmentally friendly recirculating aquaculture has gradually become a trend. But at present, do...

This not only causes a waste of water, but also increases the amount of labor

However, if solid waste such as feces in the breeding water is not discharged in time, the feces will be broken due to reasons such as swimming and aeration of the cultured objects, making it more difficult to discharge, increasing the cost of other wastes such as biofilters, etc. At the same time, it will have a certain negative impact on the water environment and endanger the growth of the breeding objects.
