Municipal sewage treatment device based on regeneration and recovery and treatment process of device

Abstract

The invention discloses a municipal sewage treatment process based on regeneration and recovery, and belongs to the technical field of sewage treatment equipment. A municipal sewage treatment device based on regeneration and recovery comprises a first shell, a second shell is arranged on the lower side of the first shell, an annularly arranged first water-soluble film is fixedly connected betweenthe first shell and the second shell, and a second water-soluble film is fixedly connected between the second shell and the second shell. A partition plate is fixedly connected into the second shell,an inner ball is fixedly connected to the circle center of the upper side wall of the partition plate and penetrates through the partition plate, a through hole is dug in the second shell and locatedunder the inner ball, an elastic sealing film is fixedly connected into the through hole, an ejector pin is inserted into the lower side wall of the inner ball, and a pressing plate is fixedly connected to the bottom end of the ejector pin, and the pressing plate is fixedly connected with the elastic sealing film. The sewage treatment device has the advantages that sewage can be effectively flocculated, oil stains on the surface of the sewage can be adsorbed and collected, the operation is simpler and more convenient, the device can be recycled while the adsorption net is recycled, and the useis more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, more specifically, to a municipal sewage treatment device based on regeneration and recovery and its treatment process. Background technique [0002] Municipal sewage, including domestic sewage, industrial wastewater and runoff sewage, is collected by the urban drainage pipe network and transported to the sewage treatment plant for treatment. The urban sewage treatment process should adopt various forms according to local conditions. Considering the natural purification of water bodies and the purification effect of sewage in the process of utilization, determine the degree of wastewater treatment and the corresponding treatment process. The treated sewage, whether used for industry, agriculture or discharged, should meet the national standards. The treated municipal sewage contains a large amount of water-insoluble debris, which will cause huge damage to the ecological environ...

Problems solved by technology

[0003] However, the existing sewage is mixed with a large amount of oil, which is very troublesome to deal with. It is necessary to separate the oil on the water surface by discharging the water through the oil-water separation box, and then carry out the next step of treatment on the sewage after separation. This method is troublesome to operate and reduces the efficiency of sewage treatment
