Abstract

The invention relates to a high efficient complex enzyme sewage treatment process which is carried out according to the following steps: (1) massive grains such as suspended substances in sewage are removed through a grid, and then the sewage enters a regulating reservoir; (2) the sewage in the regulating reservoir enters a high efficient complex enzyme catalyzing-membrane bioreactor device; (3) the sewage passes through a membrane module of the high efficient complex enzyme catalyzing-membrane bioreactor device, and clear water penetrates through the membrane module and flows out; (4) a concentrated solution which cannot penetrates through the membrane module enters a biological processing part again so as to be further catalyzed and deteriorated; and (5) the steps are repeated till the processed water reaches the reuse water discharging standard. The invention also relates to a high efficient complex enzyme sewage treatment device. The process and the device makes up the detects of the current MBR process, such as membrane pollution, high expense, and the like, and can rapidly deteriorate pollutants, rapidly and high efficiently purify the sewage, achieve good treatment effect and greatly lower the running cost for sewage treatment.

Description

technical field

[0001] The invention relates to a high-efficiency compound enzyme sewage treatment process and device, which belongs to the field of biochemical engineering and environmental science, and in particular to a process and device for sewage treatment using a high-efficiency compound enzyme catalysis-membrane bioreactor. Background technique

[0002] Membrane bioreactor process, that is, MBR process is a new type of wastewater biological treatment technology that combines modern membrane separation technology and biotechnology, also known as membrane separation activated sludge method. It uses a membrane separation device to effectively intercept the activated sludge and macromolecular organic substances in the biochemical reaction tank, replacing the secondary settling tank, so that the concentration of activated sludge in the biochemical reaction tank, that is, the biomass is greatly increased; the refractory macromolecules The organic substances are trapped in ...
