BALANCE KEEPING TYPE DECANTER FOR WASTEWATER TREATMENT

摘要

A balance keeping type decanter for wastewater treatment which allows a lateral wall of the catchment tank to maintain a predetermined slope irrespective of a water level of a wastewater tank and causes overflow to be performed to a predetermined water level through front and rear sides of the catchment tank simultaneously by freely rotating a catchment tank itself according to rotation of a catchment pipe is provided. In a rotary decanter type catchment equipment for wastewater treatment comprising: a rotary pipe(362) installed on a lower part of a wastewater tank; a catchment pipe(361) connected to the rotary pipe and an actuator(370) and axially rotated around the center of the rotary pipe; and a decanter formed on an upper part of the catchment pipe, a balance keeping type decanter for wastewater treatment is characterized in that: the decanter is formed as a rectangular catchment tank(100) of which an upper part is opened, and which has a central groove(110) formed on a lower central part thereof; the catchment pipe is formed as a "T" type branch pipe having a balance keeping pipe(120) formed on an upper part thereof; and through holes are formed in both sidewalls of the central groove, and both ends of the balance keeping pipe are respectively coupled to the through holes such that the catchment tank is freely rotated around the center of the balance keeping pipe as an axis.
