Integrated breeding sewage treatment device with microbial fermentation pretreatment

Abstract

The invention discloses an integrated breeding sewage treatment device with microbial fermentation pretreatment, and relates to the technical field of sewage treatment.The integrated breeding sewage treatment device comprises a sewage treatment box, a settling chamber, an injection pipe and a fermentation chamber, a filtering chamber is fixedly installed in the sewage treatment box, and the settling chamber is fixedly installed at the bottom of the filtering chamber; and the injection pipe is fixedly connected to the side face of the settling chamber, and the fermentation chamber is fixedly mounted on the side, away from the settling chamber, of the injection pipe. Through mutual cooperation of a rotating pipe, a push block, a power motor, a moving hole and a rotating hole, the power motor is connected with a power supply, so that the rotating pipe rotates in the filtering chamber, and the rotating hole scrapes sticky substances in aquaculture sewage to accelerate flowing of the aquaculture sewage; and the problem that a filtering layer is blocked due to the fact that the concentration of sticky matter in the breeding sewage in the filtering chamber is too large is solved, flowing in the filtering chamber can be improved, and therefore the breeding sewage can be conveniently filtered through the filtering chamber.

Description

technical field [0001] The invention relates to a sewage treatment device and relates to the technical field of sewage treatment, in particular to an integrated breeding sewage treatment device with microbial fermentation pretreatment. Background technique [0002] In the treatment of aquaculture sewage, since the sewage contains a large amount of feces and other impurities, the organic components and other substances in the feces will dissolve into the sewage after being soaked in water, which will increase the concentration of pollutants in the sewage and increase the difficulty and cost of sewage treatment. , so that the way of microbial fermentation pretreatment is used to treat sewage, thereby reducing the treatment cost. There are following problems at prior art: [0003] 1. Since the integrated aquaculture sewage treatment device needs solid-liquid separation during operation, the viscosity is relatively high during solid-liquid separation, which is likely to cause b...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides an integrated aquaculture sewage treatment device with microbial fermentation pretreatment, one purpose of which is to have the function of stirring to solve the problem that the viscosity is relatively high during solid-liquid separation, which is likely to cause blockage of the filter layer, thereby It makes the device unable to carry out the problem of solid-liquid separation; another purpose is to solve the problem that the pressure inside and outside the fermentation device is different, so that when a certain amount is injected, it is easy to cause the phenomenon of reflux, so that the waste liquid cannot be fermented. Achieve the effect of increasing the pressure of the injection pipe and preventing the backflow of waste liquid
