Abstract

The invention discloses a sewage pretreatment multi-effect purification device, which comprises a casing, wherein a support plate is fixedly connected onto the left side of the top of the casing; thebottom of a movable plate is glidingly connected with the top of the casing; the top and the bottom of the right side of the movable plate are fixedly connected with connection springs; the right sideof the connection springs is fixedly connected with the top of the casing through a support rod; the sewage pretreatment multi-effect purification device relates to the technical field of sewage treatment purification. The sewage pretreatment multi-effect purification device is characterized in that the support plate is fixedly connected onto the left side of the top of the casing; the viscosityof the water in a barrel can be judged according to the detected sewage weight; then, the rotating speed of a rotating rod is regulated according to different viscosities, so that a filtering barrel can be driven to rotate at the optimal rotating speed to filter the sewage; therefore, the sewage purification efficiency is improved; the power consumption is reduced; great convenience is brought tothe use by people. The problem that the existing sewage pretreatment multi-effect purification device cannot realize the optimal purification on the sewage according to the viscosity of the sewage.

Description

technical field

[0001] The invention relates to the technical field of sewage treatment and purification, in particular to a sewage pretreatment multi-effect purification device. Background technique

[0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage include pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants, etc. According to the point of view of sewage sources, sewage can be defined as groundwater and surface water discharged from residential, institutional, commercial or industrial areas , blizzard, etc. mixed liquid or water carrying waste. There are many types of sewage, and correspondingly there are many technologies and processes to reduce the impact of sewage on the environment. According to the source of sewage, sewage can be divided into these four categories. The fi...
