Drainage system with rainwater treatment function

Abstract

The invention relates to a drainage system with a rainwater treatment function. The drainage system comprises a first rainwater treatment pond and a second rainwater treatment pond, the first rainwater treatment pond communicates with the second rainwater treatment pond, a rainwater collector is arranged on one side of the first rainwater treatment pond, the rainwater collector communicates with the first rainwater treatment pond, a cutting device is arranged on the first rainwater treatment pond, a sludge digging device is arranged on the second rainwater treatment pond, a reservoir is arranged on one side of the second rainwater treatment pond, the reservoir communicates with the second rainwater treatment pond, an excrement flushing pipe is arranged on one side of the reservoir, the excrement flushing pipe communicates with the reservoir, the other end communicates with a household closestool, and the closestool communicates with an urban sewage pipe. According to the drainage system with the rainwater treatment function, silt, impurities and other solid particles in rainwater are advantageously separated from the rainwater, then the rainwater after separation is completed is used for flushing the closestool, on one hand, pollution of the impurities and silt in the rainwater to river water can be reduced, and on the other hand, the effect of saving water resources can be achieved.

Description

technical field [0001] The present application relates to the technical field of drainage, in particular to a drainage system with rainwater treatment. Background technique [0002] At present, the drainage system mainly includes diversion system, confluence system and mixed flow system, and its main purpose is to realize the collection, transportation and treatment of water bodies. The system that treats different types of wastewater in different ways is called the diversion system, which generally has two drainage systems. One can be called a rainwater system, which is used to collect rainwater and industrial wastewater with a very low pollution level that is directly discharged into the water body without treatment, and its pipeline is called a rainwater pipeline. The other can be called a sewage system, which collects domestic sewage and industrial wastewater that needs to be treated before it can be discharged, and its pipeline is called a sewage pipeline.
