Sewage treatment reaction tank and sewage treatment method

Abstract

The invention discloses a sewage treatment reaction tank and a sewage treatment method. The sewage treatment reaction tank comprises a reaction tank body, a stirring unit, a power unit, a precipitatedischarge unit, a sludge dewatering agent storage unit, a disinfectant adding unit and a sludge separation unit, wherein a tank cover is arranged at the top of the reaction tank body, the interior ofthe reaction tank body is divided into a precipitation cavity, an anaerobic cavity and a disinfection cavity from left to right through a first partition plate and a second partition plate, at least three branch pipes are arranged on the left side of the reaction tank body in a penetrating mode and connected with the side face of a water conveying pipe, and a first water valve is arranged at the end of the water conveying pipe. According to the invention, only one power mechanism needs to be adopted for stirring and injecting a sludge dewatering agent, so that electric power is saved, injecting and stirring can be conducted at the same time, precipitated sludge is convenient to collect and take out, subsequent sludge precipitation is not affected, the use efficiency is high, anaerobic treatment can be rapidly achieved, a disinfectant can be added subsequently, and the sewage treatment effect is good.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment reaction tank and a sewage treatment method. Background technique [0002] In the current ordinary sewage treatment, the reaction tank is usually used for sludge sedimentation and anaerobic treatment, and then discharged, but for sludge sedimentation, two power devices, stirring and adding sludge dehydration agent, are usually required, and The settled sludge is also inconvenient to collect, thus affecting the subsequent sludge precipitation, and the anaerobic treatment efficiency is low. Contents of the invention [0003] The technical problem to be solved in the present invention is to overcome the existing defects, provide a sewage treatment reaction tank and a sewage treatment method, only need to use one power mechanism for stirring and filling the sludge dehydration agent, save power, and can stir while filling, The settled sludge is easy to c...
