Problems solved by technology

[0011] The present invention provides a negative pressure operated reverse osmosis filtration membrane system. The filtration membrane adopts a central interlocking fastening unit structure, which can be combined without a shaft column. In addition, the operating pressure of the system is low, and there is no water leakage during use. Or the risk of sewage infiltration into the system; used to solve the problem of poor watertightness and easy leakage of known flat filter units

Abstract

The invention discloses a negative pressure operation type reverse osmosis filterable membrane system which includes a reverse osmosis filterable membrane unit, a locking unit, a water tight element, a top cover and a bottom cover. The reverse osmosis filterable membrane unit has a membrane supporting plate showing sandwich structure, a first membrane and a second membrane, a chamber definite by the membrane supporting plate, the first membrane and the second membrane for water body to dialysis, and a water generating hole throughout axially and connected with the chamber. The locking unit and the reverse osmosis filterable membrane unit are interleaving telescoped mutually, the locking unit has a leading plate for clamping the reverse osmosis filterable membrane unit, then the locking unit and the reverse osmosis filterable membrane unit are kept water tight state by using the water tight unit. The top cover has an admission port connected with the water generating hole for supplying a negative pressure that water body dialyzed from the membrane is lead to system outside.

Description

technical field [0001] The invention relates to a sewage filtration system, and in particular to a negative pressure operation type reverse osmosis filtration membrane system with low power, easy membrane cleaning, and avoiding concentration polarization. Background technique [0002] At present, the wastewater recycling method using membrane separation technology is one of the common practices in the industry, especially in the advanced tertiary treatment of drinking water, which has a very good solid-liquid separation effect. Therefore, in recent years, membrane systems have been used for recycling. The technology of separation and purification has been paid more and more attention. [0003] The appearance types of membrane groups in the prior art are mainly divided into two categories, one is tubular membranes, such as spiral-wound, hollow-fiber and tubular, and the other is tubular. One is a flat-sheet membrane. Although the spiral and hollow fiber membranes use high pa...
