Further, for realizing better the utility model, above described filtering cabin, be provided with dosing mouth.
Further, for realizing better the utility model, described elastomeric element is selected spring, and described spring is initially in relaxed state.
Further, for realizing better the utility model, on described filtering cabin outer wall, be provided with liquid level gauge.
Further, for realizing better the utility model, on described outlet pipe, be connected with pump.
The utility model compared with prior art, has following beneficial effect:
(1) the utility model project organization is simple, when can effectively realizing sewage water filtration, utilizes sewage self pressure to realize sewage water filtration, and has backwash function, can realize recycling of equipment, saves the energy;
(2) the utility model, by dosing mouth is set, can directly carry out dosing to sewage in sewage disposal process, eliminates the part harmful substance in sewage;
(3) the utility model, can be in the position of automatic reduction filter membrane after sewage permeation filter membrane by adopting spring as elastomeric element, is convenient to continue to use, and is also convenient to filter membrane to carry out backwash;
(4) the utility model, by outlet pipe, pump being set, can adopt pump to inhale the inner filtered sewage of filtering cabin when needed, accelerates sewage water filtration speed and efficiency.
