Sewage collecting tank with automatic pumping drainage starting and stopping function

Abstract

The invention disclosed belongs to the technical field of sewage collection tanks, and is specifically a sewage collection tank with an automatic start-stop pumping function, including a primary sedimentation tank, a tertiary treatment tank, a secondary sedimentation tank and a tertiary sedimentation tank. The first pumping pipe is installed on the right side of the first-level settling tank, the top of the three-level treatment tank is equipped with a second-level treatment tank, and the top of the second-level treatment tank is equipped with a first-level treatment tank. The present invention uses the traditional three The treatment tank is changed to a gradient potential treatment tank, which not only saves the floor area, but also facilitates the circulation of sewage through sufficient water pressure, and through the treatment tank with increasing volume, it is convenient for a part of the sediment to settle in the bottom of the three tanks driven by the water flow In the first-level treatment tank, and by installing a float switch in the sedimentation tank, it is convenient to automatically start and stop the pumping function to prevent the long-term operation of the pump, and to increase the mud discharge effect of the sedimentation tank by installing a rotating disc and a mud scraper. Prevent clogging.

Description

technical field [0001] The invention relates to the technical field of sewage collection pools, in particular to sewage collection pools with automatic start-stop pumping and drainage functions. Background technique [0002] When the special treatment liquid for printed circuit boards is produced, a large amount of chemical wastewater will be produced, which cannot meet the needs of sewage discharge. Therefore, these chemical wastewater need to be preliminarily filtered before being discharged to a special sewage treatment plant. However, the current After preliminary sedimentation, three additional sets of treatment agent addition pools are required, which requires a large area. Therefore, it is necessary to reduce the floor space while retaining the role of treatment agent for treatment in separate processes, and the existing sewage collection pools are passed Manual control of the water in and out is prone to overflow due to excessive water intake or low water level causi...
