Large sewage treatment device capable of easily cleaning impurities

Abstract

The invention discloses a large sewage treatment device capable of easily cleaning impurities. The device comprises a wastewater filtering box and a control box, a cleaning assembly and an ultravioletsterilization lamp are arranged on the upper side of the interior of the wastewater filtering box; a first liquid inlet penetrates through the upper side of the wastewater filtering box; a sealing pipe is rotationally connected with a filter screen through a bearing; a conveying belt penetrates through the lower side of the interior of the wastewater filtering box, the sealing pipe is communicated with a centrifugal machine through a first wastewater pipe, a pressurizing pump is arranged on a second wastewater pipe, and the rear sides of the first wastewater pipe and the second wastewater pipe are both communicated with a waste liquid evaporation and concentration assembly through connecting pipes. By arranging the sealing pipe, the filter screen and the conveying belt, wastewater filtered by the filter screen is stored in the sealing pipe, the filter screen rotates under the impact of the wastewater, in this way, circulating filtration can be conducted, and a small part of wastewaterin the impurities can be filtered again under the action of holes in the conveying belt.

Description

technical field [0001] The invention relates to the technical field of sewage, in particular to a large-scale sewage treatment device that can easily remove impurities. Background technique [0002] Sewage refers to the polluted discharge water from domestic and production. According to the source of sewage, sewage can be defined as mixed with groundwater, surface water, snowstorms, etc. liquid or water. There are many types of sewage, and correspondingly there are many technologies and processes to reduce the impact of sewage on the environment. [0003] The existing sewage treatment device is not convenient for fast separation and treatment after filtering the impurities in the sewage, which is time-consuming and laborious, and the general impurities are not crushed and dried after treatment, and the sewage is prone to dripping when the impurities are transported. Cause the second pollution. At the same time, after the general sewage is filtered, it is directly sterilize...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a large-scale sewage treatment device that is easy to remove impurities, so as to solve the problem that the existing sewage treatment device proposed in the above background technology is not convenient for rapid separation and treatment after filtering the impurities in the sewage, and the general Impurities are not crushed and dried after treatment, and if the amount of heavy metals, pathogens or toxic organic substances contained in the mud exceeds the relevant standards, it will endanger the health of the soil and human beings.
