The invention provides a
sewage treatment deodorization device, and relates to the technical field of
sewage treatment, the
sewage treatment deodorization device comprises an underneath channel, the rear end of the underneath channel is fixedly provided with a
tail seat, the front end of the underneath channel is fixedly provided with a head seat, and a spiral
propeller is rotatably arranged in the
tail seat and the head seat; a first motor is fixedly arranged outside the head seat and is in transmission connection with the spiral
propeller; a middle bin is fixedly arranged at the top of the lower channel in a sealed mode. An upper channel is fixedly arranged at the top of the middle bin. The device is provided with a strip-shaped frame, a synchronous driving function of conveying sewage and adding a
deodorant and a flocculating agent is provided, the strip-shaped frame can convey the sewage and can also make contact with a trigger piece in the backward moving process, a control
piston is extruded, and a liquid material in the control
piston penetrates through a one-way valve B to be input into an upper channel for filling; meanwhile, the
powder feeder is driven to move back and forth to automatically supplement
powder, so that automatic deodorization,
flocculation and conveying are realized, and the problem that an existing deodorization device is inconvenient to automatically add
powder in equal proportion is solved.
