Microbial flora mother liquor incubator and sewage treatment method thereof

Abstract

The invention relates to a microbial flora mother liquor incubator. The microbial flora mother liquor incubator comprises an outer box, a water tank, an oxygen supply device, a water supply device, a sewage discharging device and a biological filler layer, wherein the biological filler layer comprises a sunken biological filler layer, a suspended biological filler layer and a floating biological filler layer; each of the sunken biological filler layer, the suspended biological filler layer and the floating biological filler layer comprises a plurality of biological fillers; the sunken biological filler layer, the suspended biological filler layer and the floating biological filler layer are sequentially arranged in a biological filler bin from bottom to top. The biological filler layer is provided with the sunken biological filler layer, the suspended biological filler layer and the floating biological filler layer, the biological fillers in each layer float up and down in the layer in the corresponding static pressure range, a relatively-stable breeding and growing environment can be created for all microorganisms, the microbial flora mother liquor incubator is suitable for breeding and growing of all the microorganisms, the cultivation efficiency of the microorganisms is greatly improved, the sewage treatment effect is greatly improved, and the structure is quite simple.

Description

technical field [0001] The invention relates to a microorganism cultivating device, in particular to a microbial flora mother liquid incubator for sewage treatment and a sewage treatment method thereof. Background technique [0002] Water resources are the most important resources for human life, but the massive discharge of domestic sewage, industrial sewage and livestock wastewater has caused more serious damage to water resources and the water environment, so it is becoming more and more difficult to manage and restore water resources. Big. [0003] At present, the use of microorganisms for sewage treatment has become an important sewage treatment method. The equipment used is a microbial flora mother liquor incubator, which generally includes an outer box, a water tank, an oxygen supply device, a water supply device, a sewage discharge device and a biological filler layer. The water tank is arranged on the side wall of the outer box, and the oxygen supply device, the wa...

AI Technical Summary

Problems solved by technology

However, the height and position of the above-mentioned biological fillers in the box are constantly changing, which cannot create a relatively stable breeding and growth environment for various microorganisms, resulting in low microbial culture efficiency, making it difficult to efficiently treat sewage, and undoubtedly increasing sewage pollution. processing cost

For example, if a certain type of microorganism hangs a film at a relatively deep position for a period of time, when it is impacted by water and air and rises to a higher position, this type of microorganism cannot reproduce and grow slowly or even die due to the difficulty in adapting to the lower static pressure. One type of microorganism re-hangs the film, but soon after, the biological filler falls to a deeper position, and the problem of slow reproduction and growth, or even death occurs. Repeatedly, the cultivation efficiency of the microbial flora is low, and it is difficult to efficiently treat the sewage treatment
