Rotary pressurization algae-reduction sewage treatment device

Abstract

A rotary pressurization algae-reduction sewage treatment device belongs to the technical field of an environmental protection device and comprises a bottom tank, a top cover plate and an algae-reduction tank. The bottom tank is provided with a bottom baffle plate; the top cover plate is provided with a top baffle plate and equipped with a first stirring mechanism, a second stirring mechanism and athird stirring mechanism in sequence; the bottom tank communicates with the algae-reduction tank through a middle outlet; a first filter body is arranged at the middle outlet; and the algae-reductiontank is internally provided with a second filter body. The device is novel in structure and clear in working principle. The first filter body arranged at the middle outlet and the second filter bodyarranged in the algae-reduction tank are used for pressurization precipitation. Compared with a traditional sewage stirring apparatus, the apparatus can fast mix sewage with a drug agent, can filter sewage impurities, improves the stirring efficiency and dehydration effect, and provides powerful guarantee for further sewage operation.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment and relates to a sewage treatment device, in particular to a rotary pressurization and algae reduction type sewage treatment device. Background technique [0002] At present, the sewage treatment process is to first add the raw mud with a high moisture content to the conditioning tank, then add the medicament to the conditioning tank, and then stir it with a mixer. After the treatment is completed, a dry mud with a low moisture content is obtained. Then proceed to the next step. The existing sewage dosing system is as follows: the solution tank, the metering pump, and the pipe and valve parts are made into an integral chassis type, and placed in a dosing room. Due to the limitation of space, the solution tank cannot be made too large. In a system with a large amount of dosing, another liquid medicine storage tank must be installed; if the dosing device is arranged at a ...
