Integrated sewage treatment device for treating vehicle maintenance wastewater

Abstract

The invention relates to an integrated sewage treatment device for treating automobile repairing wastewater, and belongs to the technical field of biological sewage treatment devices. The integrated sewage treatment device consists of an adjusting tank, a settling pond, a biological rotating disc reaction tank and a coagulation air-floating tank. The integrated sewage treatment device is characterized in that an electric control cabinet is mounted on the right side of the coagulation air-floating tank; the electric control cabinet is electrically connected with electric control units of the adjusting tank, the settling pond, the biological rotating disc reaction tank and the coagulation air-floating tank; evacuation tubes are mounted on the adjusting tank, the settling pond, the biological rotating disc reaction tank and the coagulation air-floating tank; the biological rotating disc reaction tank and the coagulation air-floating tank are connected with a pressurizing air dissolving pump. The treatment effect of the integrated sewage treatment device is superior to that of a conventional A / O process, the treatment cost can be effectively lowered, a process effluent can meet the standard, circulation of repairing water can be achieved, the water resource can be saved, and large-scale popularization and application can be facilitated. The problems in the prior art that either automobile repairing wastewater is unqualified and cannot be recycled so that the water resource is wasted, or the treatment cost is too high and large-scale popularization and application are obstructed, can be solved.

Description

technical field [0001] The invention relates to an integrated sewage treatment device for treating automobile maintenance wastewater, belonging to the technical field of biological sewage treatment devices. Background technique [0002] With the development of the times and the progress of science and technology, cars have entered thousands of households. Especially in China, which accounts for about one-fifth of the world's population, the demand for automobiles has risen sharply in recent years, accompanied by automobile maintenance wastewater that needs to be treated urgently. There are mainly two types of methods for the existing treatment of automobile maintenance wastewater, one is the simple method of using oil separation sedimentation, coagulation and then adsorption and filtration, and the other is the biochemical treatment method using the traditional A / O process; the first type of method The advantage is that the treatment cost is low, but the effect is not ideal...

Problems solved by technology

There are mainly two types of methods for the existing treatment of automobile maintenance wastewater, one is the simple method of using oil separation sedimentation, coagulation and then adsorption filtration, and the other is the biochemical treatment method using the traditional A / O process; the first type of method The advantage is that the treatment cost is low, but the effect is not ideal, and the water quality after treatment is not up to standard, so it cannot be recycled; although the treatment effect of the second type of method is very good, the treatment cost is too expensive, and it is difficult to promote it on a large scale.
