Sewage treatment environmental protection device

Abstract

The invention is suitable for the technical field of sewage treatment, and provides a sewage treatment environmental protection device which comprises: a shell, the upper end of which is provided witha water inlet and the lower end of which is provided with a water outlet; a first filtering plate which is rotatably mounted in the shell and is provided with filter holes and is fixedly connected with a first grooved pulley mechanism; a discharging plate which is rotatably mounted below the first filtering plate in the shell and is fixedly connected with a second grooved pulley mechanism; and adredging plate which is arranged above the first filtering plate in the shell, wherein a dredging rod is mounted at the lower end, and the upper end is fixedly connected with the rack; a discharge port is formed in the position, close to the discharge plate, of the shell; the dredging rod corresponds to the filtering holes in the first filtering plate in position, and the size of the dredging rodis equal to or smaller than that of the filtering holes; a fixing groove is formed in the rack and is meshed with the gear; the gear is driven by a power piece fixedly installed in the shell. According to the embodiment of the invention, the filter screen can be prevented from being blocked, and precipitated substances in sewage can be conveniently collected.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an environmental protection device for sewage treatment. Background technique [0002] Sewage refers to the polluted discharge water from domestic and production, which can be divided into industrial wastewater, domestic sewage, commercial sewage, etc. With the improvement of living standards and productivity, human beings discharge more and more sewage into the environment. The sewage will damage the environment and destroy the ecology, so it is necessary to treat the discharged sewage. [0003] At present, when the existing sewage treatment equipment treats sewage, because of the large amount of sewage to be treated, the sediment in the sewage often blocks the filter screen, which greatly affects the efficiency of sewage treatment, and the sewage inside The sediment is not easy to collect, which cannot meet people's demand for sewage treatment.
