Sewage mixing treatment device

Abstract

The invention discloses a sewage m .ing treatment device, and belongs to the technical filed of sewage treatment. The sewage mixing treatment device comprises a mixing box, a centrifugal stirring device, a pneumatic mixing device, an inner wall stirring device, a drug adding device, a sewage inlet pipe and a sewage outlet pipe; and the centrifugal stirring device is arranged in the mixing box, thepneumatic mixing device is arranged on the bottom wall of the mixing box, the inner wall stirring device is arranged on the inner wall of the mixing box, the drug adding device and the sewage inlet pipe are arranged at the top of the mixing box, and the sewage outlet pipe is arranged at the bottom of the side wall of the mixing box. According to the sewage mixing treatment device, sewage and a drug additive are stirred and mixed through centrifugal stirring, drug sedimentation and adhesion are avoided through the airflow impact and inner wall cleaning and brushing effects, by adding air and increasing the temperature, the efficiency of degrading impurities through the drug is improved, the sewage and the drug are fully mixed by adopting multiple procedures and devices for increasing the mixing degree of the sewage and the drug in the mode of drug administration at time intervals, and then the sewage purifying effect is improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and specifically refers to a mixed sewage treatment device. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. With the rapid development of economy and technology, a large amount of sewage will also be produced in people's life and work. In the sewage treatment station Chemical addition and mixing devices for sewage treatment are common equipment. By adding pharmaceutical additives to sewage, the drugs and sewage are fully mixed and react to make impurities into flocs, thereby achieving the purpose of sewage purification. However, current sewage treatment devices often appear The additives in the sewage are mixed unevenly, and the medicines are deposited and adhered to the bottom and side walls of the device, which not only affects the effect of sewage purification, but a...
