The extension raw water runner of degree.
Preferably, being equipped with water inlet grid in raw water runner, production water selvage guide is equipped with production water flow passage.By intake grid and
Produce water selvage guide and water conservancy diversion is carried out to the raw water in raw water runner and generation runner and production water respectively.
Preferably, production water flow passage only has towards the production water direction of center collector pipe, other three sides closing seam, mistake
It is equipped among the filter membrane piece back side and the corresponding production water-stop section of raw water seal section.Production water-stop section, which is set, can solve the groove
The problem of section causes membrane component production water and waste water to mix, prevent membrane element capability from failing.
Preferably, the two sides partial sealed areas adjacent with flanging of raw water runner, raw water seal section and production water
Seal section is bonded by glue.
Preferably, the position of center line cutting of filtration membrane inner surface is fluted, original is formed filled with glue in groove
Water-stop section.
Preferably, the position of production water-stop section is corresponding with the position of groove and production water-stop segment length is more than filter membrane
The length of the groove of on piece cutting.
The present invention has significant technique effect as a result of above technical scheme：
The present invention changes original runner direction, so as to increase by setting raw water seal section at the middle part of raw water runner
Raw water flow channel length, under conditions of production water back pressure is not increased, reaches and improves surface velocity and the rate of recovery.
