Problems solved by technology

[0002] At present, aquaculture is mainly at the cost of consuming a large amount of resources and sacrificing environmental interests. During the breeding process, a large amount of bait needs to be put into the water. The bait cannot be completely eaten. A considerable part of the bait exists in the water

Example Embodiment

[0027] Such as figure 1 As shown, the farming sewage recovery and treatment system according to the embodiment of the present invention includes a three-stage sedimentation filter, a microbial treatment tank 2, a plant treatment tank 4, an adsorption tank 6, and an algae treatment tank 7. The sewage generated during the breeding process passes through a The first-stage sedimentation filter 1, the microorganism treatment tank 2, the second-stage sedimentation filter 3, the plant treatment tank 4, the third-stage sedimentation filter 5, the adsorption tank 6, and the algae treatment tank 7 are processed, and the treated water is reused for breeding.

[0028] The sewage treatment process in the system is:

[0029] (1) The aquaculture sewage first enters the primary sedimentation filter 1 to remove bait, feces and particulate matter in the water;

[0030] (2) The effluent of step (1) enters the microbial treatment tank 2, and air is introduced into the microbial treatment tank 2, under ...

Abstract

A recovery and treatment system for culture waste water is disclosed. The system includes three staged precipitative filters, a microbe treatment tank, a plant treatment tank, an adsorption tank and an alga treatment tank. The culture waste water generated in a culture process flows through the first-stage precipitative filter, the microbe treatment tank, the second-stage precipitative filter, the plant treatment tank, the third-stage precipitative filter, the adsorption tank and the alga treatment tank in order and is treated. The treated water is reused for culture. The system is suitable for a factory-like aquaculture mode. The waste water generated in the culture process is subjected to biological and biochemical treatment and can reach water quality requirements on water used for culture, thus increasing the utilization rate of water and reducing the emission amount of the waste water.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a system for recycling and treating aquaculture sewage. Background technique [0002] At present, aquaculture is mainly at the cost of consuming a large amount of resources and sacrificing environmental interests. During the breeding process, a large amount of bait needs to be put into the water. The bait cannot be completely eaten. A considerable part of the bait exists in the water in the form of suspended solids or colloids. Feces will be discharged. In order to meet the growth needs of aquatic organisms, it is necessary to fill in clean water and discharge part of the sewage. If this part of sewage is not properly treated, it will pollute the river and cause damage to the ecosystem. [0003] If the aquaculture sewage can be reused after treatment, it can reduce the consumption of fresh water and the discharge of sewage to the environment, which is of great eco...
