Abstract

The invention relates to a multi-pipe internal pressure mechanical circulation forced cross current solid-liquid separation dynamic membrane system and a device thereof; wherein the dynamic membrane comprises a tubular shape internal pressure supporting body with plural number of large aperture nets, an upper orifice plate and a lower orifice plate, a shell, an upper cover and a lower cover; the upper orifice plate and the lower orifice plate are respectively provided with plural number of jack sockets, the tubular shape internal pressure supporting body is connected with the jack sockets; the shell is connected with the upper orifice plate and the lower orifice plate to form a water purification chamber; the upper cover and the upper orifice plate are connected to form a cross current backflow chamber, and the upper cover is provided with an water outlet for the cross current backflow water; the lower cover and the lower orifice plate are connected to form a water inlet chamber and the lower cover is provided with a raw water inlet thereupon. The dynamic membrane device of the invention has the advantages of no water power dead angle, short pre-coating time, convenient back wash, continuous work, improved dynamic membrane flux, stable water yield and long work period.

Description

technical field [0001] The invention relates to water supply / sewage treatment technology, in particular to a multi-pipe internal pressure mechanical circulation forced cross-flow solid-liquid separation dynamic membrane system and device capable of reducing hydraulic dead angles. 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) ...
