Treatment device for high-salinity coking sewage

Abstract

The invention belongs to the technical field of sewage treatment equipment, and particularly relates to a treatment device for high-salinity coking sewage. The high-salinity coking sewage treatment device comprises a sewage treatment assembly and a water pumping mechanism, the water pumping mechanism comprises a shell, a water outlet pipeline, water inlet filter plates and water inlet units, the shell and the two adjacent water inlet filter plates define water filtering cavities, and one water inlet unit is arranged in each water filtering cavity in a one-to-one correspondence mode; the water inlet unit is provided with a water inlet and a water outlet, the water inlet extends out of the shell to allow sewage to enter, the water outlet is communicated with the water filtering cavity, the size of the water inlet is adjustable, and when the included angle between every two adjacent water inlet filter plates is increased, the water inlet is shrunk or closed. When the sewage treatment device is used, the blocked water inlet filter plate can be automatically cleaned by virtue of the pressure difference generated in the two adjacent water filtering chambers, so that the water pumping mechanism is not easy to block, and the working efficiency of the sewage treatment device is improved.
