[0002] The suspended filler pool is a kind of equipment applied to sewage treatment, mainly including biochemical pool, anaerobic tank and aerobic tank etc..Its application is very extensive, and is applied in industrial, medical, sewage treatment industry such as life. Suspended filler pool is by putting suspended filler in water, biological membrane is formed on the surface of filler, these biological membrane can adsorb and degrade organic matter and pollutants in water. Double-layer design of filler makes microorganism more easily attach and grow, and its high porosity and strong hydrophilicity help to improve biological treatment efficiency. In the application of suspended filler pool, filler keeps suspended state under aeration and mechanical stirring condition, in order to prevent filler from flowing away with sewage through water outlet, intercepting screen is installed at the water outlet of filler pool to intercept filler. The existing suspended filler pool outlet intercepting screen is mostly vertically arranged flat plate type, due to the principle of floating object flowing with fluid, sludge and filler are easy to gather and block mesh at screen, on the one hand, it affects water discharge efficiency, on the other hand, filler gathers at intercepting screen, cannot contact with sewage well, also can reduce biofilm formation speed, so as to cause less biological attachment, which is not conducive to the growth of bacterial strains. Therefore, it is very inconvenient to disassemble and clean intercepting screen frequently.

[0003] Therefore, the Chinese utility model patent with authorization announcement No. CN208055009U discloses a device for cleaning filler accumulated on the net screen at the water outlet of aerobic tank. Although it can drive the scraper assembly to move up and down by the electric lifting mechanism to clean the net screen device. However, due to the need of electric lifting mechanism and scraper assembly, the structure is complex, not only high in cost, but also needs frequent maintenance, which is inconvenient to use.

[0011] Working principle and process:

[0012] In use, the utility model is fixedly connected to the inner side wall of the filler pool wall body through the mounting frame, so that the screen mesh is located at the upstream end of the water outlet, and when sewage flows out through the water outlet, since the screen mesh is inclined, the impact force of the sewage on the screen mesh has a downward component force, so that the sludge gathered at the screen mesh is separated from the screen mesh and moves downward along the inclined surface of the screen mesh and returns to the filler pool, effectively preventing the sludge from blocking the screen mesh and achieving the self-cleaning function.

[0013] Compared with the prior art, the utility model has the beneficial effects that:

[0014] The suspended filler pool outlet intercepting screen effectively prevents the sludge from blocking the screen mesh, increases the durability of the screen mesh, reduces the cleaning frequency of the screen mesh, and saves manpower.

[0015] The suspended filler pool outlet intercepting screen has the advantages of simple and stable structure, low manufacturing cost and good application effect. DRAWINGS
