Rainwater sewage treatment system

Abstract

The invention relates to the field of water treatment, and particularly relates to a rainwater sewage treatment system. The rainwater sewage treatment system comprises a discharge pipe, a sewage pipe and a rainwater pipe, wherein a transfer station is arranged between the discharge pipe and the sewage pipe and the rainwater pipe; one end, far away from a road surface, of the discharge pipe is fixedly connected and communicates with the transfer station; one end of the sewage pipe is fixedly connected and communicated with the transfer station, and the other end of the sewage pipe communicates with a sewage treatment plant; one end of the rainwater pipe is fixedly connected and communicates with the transfer station, and the other end of the rainwater pipe communicates with a river channel; the rainwater pipe and the sewage pipe are not opened and closed at the same time; and a conversion device for converting the opening and closing states of the rainwater pipe and the sewage pipe is arranged between the rainwater pipe and the sewage pipe. According to the rainwater sewage treatment system, the opening states of the rainwater pipe and the sewage pipe are converted, sewage and rainwater are separated, the process of purifying the rainwater by the sewage treatment plant is reduced, and the effect of reducing the power consumption waste of the sewage treatment plant is achieved.

Description

technical field [0001] The present application relates to the field of water treatment, in particular to a rainwater treatment system. Background technique [0002] The rainwater sewage treatment system is very important in urban construction. The rainwater sewage treatment system is used to discharge the domestic sewage and rainwater in the city smoothly, so as to reduce the impact of rainwater sewage on urban life. [0003] The general rainwater treatment system adopts the drainage method of combined rainwater and sewage system, uses the same drainage pipe to discharge domestic sewage and rainwater, and discharges the rainwater into the sewage treatment plant together, and the sewage treatment plant treats the rainwater and discharges it after the water quality reaches the standard into the river to reduce pollution to the river. [0004] Regarding the above-mentioned related technologies, the inventor believes that there are the following defects: rainwater can be direct...
