Pretreatment device for efficient sewage treatment

Abstract

The invention discloses a pretreatment device for efficient sewage treatment, which comprises a device body; the device body is mainly composed of a base, a box body, a water inlet, a water outlet, a filtering cavity and a stirring cavity; the filtering cavity and the stirring cavity It is separated by a rotating plate, and the rotating plate is rotatably connected with the inner wall of the box; a fixed plate is arranged in the filter cavity, and the fixed plate and the rotating plate are fixedly connected by a filter element, the top of the box is fixedly connected with the first motor, and the bottom of the box Both sides are fixedly connected with vibration motors, the vibration motors are electrically connected with the power supply outside the device body, the bottom of the box is fixedly connected with telescopic devices, the ends of the telescopic devices are fixedly connected with magnets, and the surface of the base is fixedly connected with magnets. The device avoids the local overload of the filter element and the clogging of the filter element, improves the filtration efficiency of the sludge, improves the stirring range of the sewage, and uniformly distributes the microorganisms, greatly improves the anaerobic treatment effect of the sewage, and facilitates the depth of the sewage in the later stage. deal with.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a pretreatment device for efficient sewage treatment. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, the discharge of sewage in our country is also gradually increasing. Before discharge, sewage needs to be treated, and it can only be discharged after the treatment reaches the standard. [0003] The sewage treatment process is complicated. Before the sewage is treated, it needs to be pretreated to facilitate the advanced treatment of the sewage in the later stage and to improve the treatment efficiency of the sewage. [0004] There are many methods of sewage pretreatment, such as biological aerobic treatment, biological anaerobic treatment, etc. The biological anaerobic treatment mainly uses microorganisms to degrade the pollutants in the sewage under anaerobic conditions inside the sewa...

Problems solved by technology

[0004] There are many methods of sewage pretreatment, such as biological aerobic treatment, biological anaerobic treatment, etc. The biological anaerobic treatment mainly uses microorganisms to degrade the pollutants in the sewage under anaerobic conditions inside the sewage. Before the biological anaerobic treatment, it is necessary to Sludge filtration for sewage is convenient for the advanced treatment of sewage in the later stage. However, in the process of filtering sludge in sewage, the filter element is relatively large, and it is prone to clogging, which brings inconvenience to sewage treatment.
