Problems solved by technology

However, the biofilm on the surface of the filler is greatly affected by the aeration system, and a good biofilm cannot be guaranteed. At the same time, the influence of the mixed liquid sludge must be taken into account. The actual operation stability is poor, and a good treatment effect cannot be guaranteed.

Abstract

The invention relates to a film separating biology reactor to realize film pollution problem. The solid and liquid separating film component and the first non-bubble aeration biology film component are set in biochemical reaction vertically. The solid and liquid separating film component and the first non-bubble aeration biology film component are paralleling. The separating film component connects to water outlet pipeline, and the suction pump connects to water outlet pipeline in series. The invention is placed with solid liquid separating film alternating. The aerator pipe and distributing pipe are set between two films. It is benefit to fully mix organic pollutant and active sludge. It could effectively solve the film pollution problem.

Description

technical field [0001] The present invention relates to a membrane bioreactor. Background technique [0002] Membrane bioreactor (MBR) is a new and efficient sewage treatment technology that combines membrane separation technology and traditional biological treatment process. Using ultrafiltration membrane or microfiltration membrane to replace the traditional secondary sedimentation tank for solid-liquid separation can realize the separation of sludge retention time (SRT) and hydraulic retention time, and allow a longer SRT, which is suitable for the treatment of high-concentration refractory organic waste water. [0003] Membrane fouling has always been an important factor restricting the development of membrane bioreactors. Membrane bioreactors need to maintain a high mixed liquid suspended solids concentration (MLSS), but a higher sludge concentration will increase the fouling speed of membrane bioreactors. , Many studies have adopted the method of placing fillers in t...
