Abstract

The invention provides a wastewater treatment system for breeding brood shrimps. The system comprises a sewage treatment tank, and a first partition plate is arranged in the sewage treatment tank. The first partition plate divides the sewage treatment tank into a first cavity and a second cavity, a sewage treatment cavity is formed in the other side of a second partition plate, guide plates and convex blocks are sequentially and symmetrically arranged on the inner wall of the first cavity from top to bottom, and the guide plates and the convex blocks divide the first cavity into a vertical part, a rotating part and a deposition part. A rotating piece is arranged in the rotating part, the rotating piece is connected with a rotating driving mechanism, a second partition plate with a notch in the bottom is arranged in the second cavity, a water conveying channel is formed between the second partition plate and the first partition plate, a sewage treatment device is arranged in the sewage treatment cavity, and a water guide pipe is arranged on the vertical part. The water guide pipe communicates with the water conveying channel, a pump core impeller is arranged at the end of the water guide pipe, and an impeller control device used for controlling the pump core impeller is arranged in the second partition plate.

Description

Technical field

[0001] The present invention relates to the field of wastewater treatment, in particular, to a wastewater treatment system for breeding shrimps. Background technique

[0002] During the rectification process of shrimp breeding, all of the breasts are emptied and injected into the new water, so the raw shrimps contain a large amount of sand and shrimps, dead shrimp and feed residue, and their ingredients The concentration of contaminants such as organics and nitrogen and phosphorus is high, and the biochemical properties are better. These high concentrations of organic wastewater will cause emitting eutrophication in water, so that dissolved oxygen in the water is consumed, so that the surrounding water body The stinky is black, which not only causes a serious hazard near the water near the shrimp farm, but also hinders the sustainable development of the breeding industry. If the wastewater is treated, the wastewater contains a large amount of sand is not easy to s...
