Embodiment Construction

[0013] In order to make the technical means, creative features, objectives and effects of the invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.

[0014] A preferred embodiment of the present invention is to provide a multi-stage high-efficiency MABR membrane sewage treatment device. Energy consumption; in MABR biofilm, oxygen, organic matter and nutrients in water are mass-transferred, so MABR biofilm is actually a nitrifying biofilm, that is, heterotrophic bacteria and autotrophic bacteria will not conflict, which is easier Nitrification is better carried out on the entire biofilm interface, while denitrification is carried out in the external mixed solution to realize simultaneous nitrification and denitrification in the same reaction tank; the combination of multi-stage biochemical tanks and aerobic tanks is used to realize the biofilm system and realize a single The microorganisms in the reactor...

Abstract

The invention discloses a multistage efficient MABR membrane sewage treatment device. The device comprises a tank body, a biological membrane purging fan, an aeration fan, an oxygen permeation fan, awater feeding pipe, a water discharging pipe and a return pipe. First, second, third and fourth partition plates are sequentially installed in the tank body to sequentially divide the interior of thetank body into a first-stage MABR tank accommodating a first MABR membrane assembly, a second-stage MABR tank accommodating a second MABR membrane assembly, a third-stage MABR tank accommodating a third MABR membrane assembly, an aerobic tank accommodating an aeration disc and a secondary sedimentation tank. The bottoms of the first, second and third MABR membrane assemblies are provided with purging aeration pipes. Each purging aeration pipe is communicated with the biological membrane purging fan. The tops of the first, second and third MABR membrane assemblies are communicated with the oxygen permeation fan.

Description

technical field [0001] The invention relates to the technical field of sewage treatment devices, in particular to a multi-stage high-efficiency MABR membrane sewage treatment device. Background technique [0002] Although most of the existing sewage treatment equipment can meet the requirements of sewage treatment, the traditional process also has the advantages of fast construction period, mature technology, and low comprehensive investment cost, but there are complex maintenance, large fluctuations in effluent water quality, and long-term operation energy consumption. High, comprehensive operating costs remain high. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a multi-stage high-efficiency MABR membrane sewage treatment device, which can effectively increase the oxygen transfer efficiency, improve the oxygen utilization rate, and the aeration membrane per unit volume is large, reducing the energy consumption...
