Support plate for elements of flat membrane bioreactor

Abstract

The invention discloses a support plate for elements of a flat membrane bioreactor. Water collecting flow channels are arranged on the surface of the support plate; the water collecting flow channels are connected to a water outlet; and the collecting flow channels are radial water collecting flow channels taking the water outlet as an emission point and arced water collecting flow channels, and arranged into a fan shaped. The support plate is capable of shortening the length of the water collecting flow channels, reducing the linear loss and improving the balance of negative pressure of the surface of the membrane; and therefore, the separation efficiency and the anti-fouling performance of the membrane are greatly improved; and the flat membrane bioreactor is capable of stably operating for a long time.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a support plate for a flat membrane bioreactor element. Background technique [0002] Membrane-bioreactor (MBR for short) is a world-recognized advanced sewage treatment and sewage resource technology. It is a biological reaction between ultrafiltration, microfiltration or nanofiltration membrane components in membrane separation technology and sewage biological treatment. A new type of processing system formed by the combination of processors. This integrated combined new process integrates the biodegradation of the bioreactor and the high-efficiency separation technology of the membrane. The membrane-bioreactor can deeply degrade municipal, domestic and industrial wastewater, and the treated effluent can be reused to realize the resource utilization of sewage. Membrane-bioreactors can be divided into external and submerged. Among them, the submerged membrane bioreactor can be...

AI Technical Summary

Problems solved by technology

At present, the internal flow channel structure of the support plate on the market is generally a structure connected vertically and horizontally. Such a design inevitably has some local pressure loss caused by right-angled turns. At the same time, the length of the water collection flow channel is too long, and the depth and width It is also relatively small, so the pressure loss in the work is very large, which seriously affects the separation efficiency and selectivity of the filter membrane.
