The included angle alpha between the first sewage collecting tank 5 and the horizontal direction is 75-82 degrees.
The filter screen 7 is made of a nano material which does not stick oil stains.
The filter screen 7 in the invention is made of a modified nano material which does not stick oil, and the filter screen 7 is replaced by an anti-pollution film for water with high requirement, thus realizing self-cleaning of the screen or the film. The anti-pollution membrane mainly uses a membrane prepared by modifying polyether sulfone as a membrane preparation material, and has the following beneficial effects compared with the membrane prepared from polyether sulfone:
1. the surface contact angle is small, namely the hydrophilic performance of the membrane is better. Namely, the anti-pollution effect is better;
2. the flux attenuation rate is small, namely the service cycle of the membrane is prolonged, namely the cost of the membrane is reduced;
3. the modified membrane can remove more pollutants after being back washed.
The modification process of the polyether sulfone comprises the following steps:
the method adopts gamma rays as an initiating means to carry out graft modification on the raw material polyether sulfone (PES) for membrane preparation in a homogeneous solution state.
The route of the homogeneous solution system co-irradiation grafting technology is as follows: firstly, adding a membrane material which is cleaned and purified, namely polyether sulfone (PES), into N-methyl pyrrolidone, stirring and dissolving, then adding a grafting monomer N-vinyl pyrrolidone (NVP), continuously stirring until a homogeneous phase solution is formed, then irradiating the deoxidized homogeneous phase solution by gamma rays of a radiation source, generating a plurality of active points on a polyether sulfone molecular chain through irradiation, and grafting a hydrophilic monomer NVP onto the active points to generate a branched chain. After the irradiation is finished, the grafting product is separated from the solution, the structure and the property of the grafting product are analyzed and characterized, and finally the obtained grafting product PES-g-PVP is used for preparing the membrane.
The working process of the invention is as follows: the filter element is arranged in a filter to carry out filtering work, sewage enters the filter element, the sewage enters the filter screen 7 from the outside of the filter screen 7 through the filtering of the filter screen 7, the clean water passes through the filter screen 7 through the filtering of the filter screen 7, the dirt is intercepted in the first dirt collecting groove 5 and the second dirt collecting groove 6, and under the action of water flow, the dirt in the dirt collecting grooves automatically moves to the bottom end of the filter element, so that the dirt is concentrated to the bottom end of the filter element. The filth does not need to be discharged in this way, and the filter element do not need to be disassembled, so that the convenience and the rapidness are realized.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the overall concept of the present invention, and these should also be construed as the protection scope of the present invention.
