Air flotation degreasing device for sewage treatment

Abstract

The invention belongs to the field of sewage treatment equipment and specifically provides an air flotation degreasing device for sewage treatment. The air flotation degreasing device for the sewage treatment is characterized in that the air flotation degreasing device comprises a side plate, a No. 1 base plate, a No. 2 base plate, a mounting box, an automatic door, a controller, a cleaning unit,an air supply unit and a rotating plate; the No. 1 base plate is mounted on the No.2 base plate through the side plate; the mounting box is fixed on the left side surface of the side plate; the automatic door is arranged inside the mounting box; the air supply unit is used for providing air flow to sewage; the rotating plate is fixed above the No. 2 base plate through a No. 1 motor; a pollutant inlet is disposed on the left upper side of the side plate surface, while a rectangular opening is arranged on the left lower side of the side plate surface, and the automatic door is used for closing the rectangular opening; the cleaning unit is used for cleaning the air supply unit; the controller is used for controlling the operation of the cleaning unit and the air supply unit. The air flotationdegreasing device for the sewage treatment has the advantages of being used for the degreasing of domestic sewage, conducting deep degreasing of the domestic sewage, having small space occupation, ensuring automatic cleaning of vent holes of an air flotation pipe, and improving work efficiency.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment, in particular to an air flotation and oil removal device for sewage treatment. Background technique [0002] my country is a water-scarce country, and sewage treatment and reuse are effective measures to develop and utilize water resources. Sewage reuse is to use urban sewage for non-drinking purposes such as greening, washing, and supplementing ornamental water bodies after being treated by sewage treatment equipment. Household domestic sewage contains a lot of oil; directly discharged into the river will cause eutrophication of the water body; directly used for greening will pollute the soil, causing soil agglomeration and causing plant root rot. [0003] There are also technical solutions of air flotation and oil removal devices in the prior art. For example, a Chinese patent with application number 201521061095.4 discloses an air flotation and oil removal device, which belongs to th...

AI Technical Summary

Problems solved by technology

Although this technical solution can realize the automatic removal of oil stains, the technical solution can only deeply remove the oil stains by driving the sewage to rotate through the centrifugal wheel. The equipment occupies a large space, and the nozzle of the air flotation tube is blocked by oil stains or other impurities. There is no way to clean it; making the use of the invention limited
