Problems solved by technology

In high-density aquaculture, due to the high density of aquatic organisms, a large amount of toxic and harmful substances will be produced. In most cases, these toxic and harmful substances are simply discharged through drains, which will cause relatively large pollution. A small number of farms A water purification system will be added to purify the tail water of the aquaculture pond. However, the current water purification system is not specially designed for the conditions of high-density aquaculture. Water purification requirements for farming

Embodiment Construction

[0017] refer to figure 1 , a zero-emission circulating water system suitable for high-density aquaculture, including a culture pond 10, a microfilter 20, a biochemical device 30 and an aeration device 40 connected end to end through a main pipeline 91 to form a main circulation loop, The sewage outlets of the culture pond 10 , the microfilter 20 and the biochemical device 30 are connected to a sewage treatment device through a sewage pipe 92 , and the water outlet of the sewage treatment device is connected to the biochemical device 30 through a first return pipe 93 . The microfilter 20 and the biochemical device 30 can filter, decompose and purify the toxic and harmful substances in the tail water discharged from the culture pond 10, and these tail waters are then returned to the culture pond 10 after being aerated by the aeration device 40, which can effectively improve the quality of the culture. The amount of dissolved oxygen in the pond 10, the sewage filtered out by the ...

Abstract

The invention discloses a zero-emission circulating water system suitable for high-intensity aquaculture. The zero-emission circulating water system comprises a breeding pool, a microstrainer, a biochemical device and an oxygen aeration which are sequentially connected through a main pipe in an end-to-end mode to form a main circulation loop. A sewage draining opening of the breeding pool, a sewage draining opening of the microstrainer and a sewage draining opening of the biochemical device are connected with a sewage treatment device through a sewage draining pipe, and a water outlet of the sewage treatment device is connected with the biochemical device through a first backflow pipe. By means of the zero-emission circulating water system, the requirements for high-intensity aquaculture can be met, the water quality and the amount of dissolved oxygen in the breeding pool can be guaranteed, zero-emission of tail water is achieved, the ecological environment is effectively protected, the external environment cannot be polluted, the breeding cost is lowered, energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a water purification treatment system in high-density aquaculture. Background technique [0002] High-density aquaculture technology will play an important role in the future aquaculture industry, and the use of lakes, stacks, river ditches, fish ponds, etc. to develop high-density aquaculture has great potential. In high-density aquaculture, due to the high density of aquatic organisms, a large amount of toxic and harmful substances will be produced. In most cases, these toxic and harmful substances are simply discharged through drains, which will cause relatively large pollution. A small number of farms A water purification system will be added to purify the tail water of the aquaculture pond. However, the current water purification system is not specially designed for the conditions of high-density aquaculture. Clean water requirements for farming. Contents of the invention ...
