Water is when flowing through the gap between film protection device 2 and filter membrane 11, and because the gap between the rwo is smaller, its flow velocity is not
It can decline to a great extent, the pollutant in waste water is difficult to be deposited at this moment on the lateral wall of filter membrane 11, when waste water flow to film
During gap between protection device 2 and putamina 5, because gap is larger, the pollutant that waste water flow velocity occurs in rapid drawdown, waste water sinks
In waste water chamber of the product between the lateral wall of film protection device 2, i.e. film protection device 2 and putamina 5.In this way, avoiding filter membrane
11 lateral walls are contaminated, and effectively extend the service life of membrane component.Gap between film protection device 2 and putamina 5 can be with
It is convenient that the membrane component with film protection device 2 is taken out from putamina 5.In one preferred embodiment, film protection device 2

Outside the fluid export film protection device 2 of the outlet outflow of runner.In some scenarios, film protection device 2 needs to have necessarily strong
Degree is to bear higher pressure, so film protection device 2 needs to be made up of rigid material.It is provided with after cylinder, waste water is from mistake
During the raw water runner exit of filter membrane 11 to the opening 21 by cylinder, cylinder has certain control to the flow velocity of waste water
Effect.After raw water runner exit outflow of the waste water from filter membrane 11, due to the opening 21 of cylinder, so that waste water is in mistake
The flow velocity on the surface of filter membrane 11 is in more slow downward trend.In this way, the pollutant in waste water can less be deposited on filtering
The raw water runner exit of film 11 and the surface of filter membrane 11.When waste water passes through the opening 21 on cylinder (i.e. film protection device 2)
Export to outside film protection device 2, now because the space outside film protection device 2 becomes big suddenly, rapid drawdown occurs for the flow velocity of waste water.
Now because water velocity is greatly reduced, therefore pollutant in waste water can be remained in outside film protection device 2.In this way, can be with
The contaminated degree in exit of the raw water runner of filter membrane 11 is effectively reduced, meanwhile, the contaminated film protection device 2 in outer surface
It is set in outside filter membrane 11, the impurity outside residual film protection device will not have a direct impact to filter membrane 11, can so have
The service life of effect extension membrane component.

Spacing between the lateral wall of film 11 is the thickness of grid.The grid being arranged in raw water runner enables to film in filter membrane 11
There is certain interval between film, can so facilitate raw water to be flowed in filter membrane 11.When the madial wall and filter membrane of cylinder
When spacing between 11 lateral wall is the thickness of grid, waste water is from after the outlet outflow of raw water runner, and waste water is in cylinder and mistake
Between the lateral wall of filter membrane 11, waste water can not only flow between the lateral wall of cylinder and filter membrane 11, while can keep
Precipitation and then contaminated filter film 11 will not occur on the lateral wall of filter membrane 11 for the pollutant in faster flowing velocity, waste water,
So reach the purpose of protection filter membrane 11.At present using grid between 0.254mm to 1.016mm, but it is not excluded for it

To be controlled, because cylinder is made up of rigid material, after the size of opening 21 obtains control, flowed out from opening 21
The flow of water is further to be controlled.When 21 very little of opening, the pressure born at opening 21 is very big, due to cylinder
Body is rigid material, and 21 sizes of opening will not can so be always ensured that the opening 21 of a very little because pressure is big and occurs to become big,
And then ensure the stabilization of the flow for the waste water that raw water runner flows out from opening 21, i.e., the wastewater flow flowed out from the outlet of raw water runner
It is stable.For membrane component, the timing of water one of raw water tunnel inlets, if the wastewater flow of the outlet of raw water runner diminishes,
The stream of pure water quantitative change flowed out from pure water runner is big, in this way, the size for being opened in opening 21 thereon by control can be controlled effectively
Entirely the ratio between the flow for the waste water that membrane component flows out from raw water runner and the flow of pure water from the outflow of pure water runner, or perhaps certainly
The ratio between flow and the flow of raw water that is flowed into from raw water runner of the waste water of raw water runner outflow.That is, adjusting the opening 21
