Reaction environment regulatable membrane bioreaction pond for sewage treatment

Abstract

The invention discloses a reaction environment regulatable membrane bioreaction pond for sewage treatment. The reaction environment regulatable membrane bioreaction pond comprises an adjusting pond, amembrane bioreaction pond adjacent to the adjusting pond, a clean water pond adjacent to the membrane bioreaction pond and an equipment cavity adjacent to the clean water pond. Four worm wheel lead screw lifters drive an adjusting plate of the reaction pond to lift to adjust the pressure change of an inner cavity of the membrane bioreaction pond, so as to control or change the pressure of the environment in the membrane bioreaction pond, and further affect the reaction progress. Water quality can be treated by means of a water inlet slot formed in the adjusting plate of the reaction pond, a temperature control head arranged between two membrane reaction assmemblies can control the temperature in the reaction pond. In addition, a stirring motor can accelerate the reactions rate. The components are arranged above the reaction environment regulatable membrane bioreaction pond in a centralized manner, so that the reaction environment regulatable membrane bioreaction pond is compact in structure. The inner environment in the reaction pond is variable to adjust so as to meet different flora reaction demands.

Description

technical field [0001] The invention relates to the technical field of membrane bioreaction tanks, in particular to a membrane bioreaction tank with adjustable reaction environment for sewage treatment. Background technique [0002] Membrane Bioreactor (MBR) is an emerging water treatment technology, which is an organic combination of traditional sewage biological treatment process and membrane separation technology, and has been widely used in sewage treatment. The principle of membrane bioreactor is to use membrane separation technology to replace the secondary sedimentation tank in the traditional activated sludge process. Membrane bioreactors are generally composed of two parts: a membrane module and a bioreactor. According to the position of the membrane module, it can be divided into two types: separate type and integrated type. Among them, the integrated type is to install the membrane module and the bioreactor separately. The mixed solution of the bioreactor enters ...

Problems solved by technology

[0003] Most of the existing membrane bioreactors include regulating tanks, MBR reaction tanks, aeration devices, water pumps, dosing devices, disinfection devices, and control cabinets. The cooperation of the single membrane module and the aeration tube set in the membrane bioreaction tank achieves the filtering function. After the sewage enters the membrane reaction tank, it needs to be treated for a long time before the degradation of organic pollutants and the separation of mud and water can be realized. The effect is not good, the biological reaction carried out in the membrane bioreactor tank has inconsistent requirements for the environment, the nature of the sewage itself is different, and the environment entering the membrane bioreactor tank is also different, and usually the biological reaction has high requirements for the environment , the internal environment change of the membrane bioreactor designed in the prior art is relatively complicated. Even for the sewage of the same nature, if you want to change the reaction environment of the sewage reaction tank, there is no good membrane bioreactor to achieve it. Therefore, this paper The invention proposes a membrane bioreactor with an adjustable reaction environment for sewage treatment to solve the above problems
