Industrial sewage treatment device

The utility model relates to an industrial sewage treatment device which comprises a filtering mechanism (2), a precipitation bin (4) and a water pump (3), a stirring mechanism is arranged in the precipitation bin (4), a cleaning mechanism (7) is arranged at the bottom of the stirring mechanism, and the bottom of the cleaning mechanism (7) is slidably connected with the lower inner wall of the precipitation bin (4); and a blow-off pipe (17) and a medicine barrel (8) are arranged on the outer side of the precipitation bin (4). According to the sewage treatment device, impurities in sewage can be pre-filtered through the filtering mechanism, catalytic agents can be conveniently added into the filtered sewage through the arrangement of a medicine cylinder, solid particles in the sewage are rapidly coagulated and rapidly precipitated under the mixing effect of the stirring mechanism, the time needed by precipitation is shortened, and the working efficiency is improved; meanwhile, the cleaning mechanism and the bl
