Dynamic membrane support body and component for realizing water supply/sewage water treatment

Abstract

The invention provides a dynamic membrane support body and component for realizing water supply / sewage water treatment. The dynamic membrane support body for realizing water supply / sewage water treatment is used for forming dynamic membranes on the two faces of the support body and treating water supply or sewage water and comprises a flatbed type support layer, a water distribution channel, an upper water outlet, a lower water outlet and a plurality of support nets, wherein the upper water outlet and the lower water outlet are respectively arranged on two sides of the water distribution channel and are used as the operation water outlets of the dynamic membrane support body for realizing water supply / sewage water treatment so as to discharge the filtered water and to be used for the pre-coat circulating reflux of the dynamic membranes. The invention can eliminate the water power dead corner inside the dynamic membrane support body for realizing water supply / sewage water treatment tothe largest extent, can reduce the pre-coat time during operation and ensure output water quality.

Description

technical field [0001] The invention relates to water supply or sewage treatment technology, in particular to a dynamic membrane support body and components capable of reducing hydraulic dead angles and realizing water supply / sewage treatment. Background technique [0002] In the 21st century, water treatment membrane separation technology has become more and more widely used. Dynamic membrane separation technology, due to its relatively low investment cost, easy control of membrane fouling, and low energy consumption, has become a hot spot in current membrane research. [0003] Dynamic membrane (Dynamic membrane) can also be called secondary membrane (second membrane), which refers to a new membrane formed on the surface of microfiltration membrane, ultrafiltration membrane or large-pore support by precoating agent or activated sludge. The formation of a dynamic membrane can slow down the clogging (Block) and membrane fouling (Fouling) of the microfiltration membrane, ultr...
