Multi-section combined sewage treatment system

Abstract

The invention provides a multi-section combined sewage treatment system. The multi-section combined sewage treatment system comprises a main body; a water inlet pipe is fixedly mounted at the top of the main body, a driving part is mounted in the water inlet pipe, a partition plate is fixedly mounted in the main body, a limiting part is mounted at the bottom of the partition plate, a cleaning part is fixedly mounted at the top of the partition plate, and a fixing block and a controller are fixedly mounted on the bottom side in the main body; a flow guide part is mounted on the main body; a pushing part is mounted in the main body; a filtering part is mounted at the top of the main body, and a drainage part is mounted on the right side of the filtering part; and a backflow part is arranged inside the main body. The sewage treatment quality is improved; when a water quality detector detects that sewage in a drainage pipe meets the discharge requirement, the controller opens an electromagnetic valve and closes a water suction pump at the same time, the filtering quality of the sewage is guaranteed, water discharged by the drainage pipe meets the discharge requirement, intelligence is high, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and more specifically relates to a multi-stage combined sewage treatment system. Background technique [0002] The sewage contains more impurities and sediment, and it can be used after being treated by sewage treatment equipment. [0003] Based on the above, the inventors have found that the current sewage treatment device is prone to clogging of the filter when it is in use, thereby reducing the efficiency of sewage treatment, and the current sewage treatment device, when cleaning the internal sediment, the staff can only stop and clean. The sediment in the sewage cannot be discharged when the device is in use, and the current sewage treatment device cannot guarantee that the treated sewage meets the discharge requirements, which is easy to cause pollution to the environment and is not easy to use. The existing sewage treatment device cannot meet the contemporary requirements. Usage r...
