Community rainwater utilization system based on secondary split-flow of rainwater and sewage

Abstract

The invention provides a community rainwater utilization system based on secondary split-flow of rainwater and sewage. The community rainwater utilization system based on the secondary split-flow of the rainwater and the sewage at least comprises a rainwater and sewage diffluent split-flow pipe network which is arranged below the earth surface, a water quality monitoring, control and split-flow device, a rainwater flow discardingdevice, a rain collection device, a sedimentation tank and a pelelith treating pond. The rainwater and sewage diffluent split-flow pipe network comprises a rainwater collection pipe, a rainwater confluence pipe, a sewage discharging pipe and a sewage confluence pipe. An available rainwater inlet pipe is connected with the rain collection device. The rain collection device at least comprises a rain collection pond and a sand blocking board. A water outlet of the sedimentation tank is communicated with the pelelith treating pond. The pelelith treating pond is filled with pelelith filter materials. A water outlet of the pelelith treating pond leads to the water quality monitoring, control and split-flow device. The community rainwater utilization system based on the secondary split-flow of the rainwater and the sewage can carry out split-flow on rainwater and the sewage in a community, concentratedly collects the rainwater to carry out a second split-flow, and then carries out treatment on the rainwater. The community rainwater utilization system based on the secondary split-flow of the rainwater and the sewage monitors the water quality which is treated and discharges water in a split-flow mode, and the water is recycled. The community rainwater utilization system based on the secondary split-flow of the rainwater and the sewage is simple in structure and easy to operate.The invention provides a community rainwater utilization system based on secondary split-flow of rainwater and sewage.

Description

technical field [0001] The invention relates to a residential rainwater utilization system based on the secondary diversion of rain and sewage, in particular to a system capable of diverting rain and sewage, collecting, treating, monitoring and diverting discharge at the same time. Background technique [0002] With the increasing scarcity of water resources, the recycling of water resources has attracted more and more attention. Because natural rainwater has the advantages of low hardness and less pollutants, it is increasingly becoming an important topic in reducing urban rainwater hazards and developing water sources. For example, roof and ground rainwater in residential areas, building groups, etc., after collection and certain treatment, can be used for landscape environment, greening, car wash water, road washing, cooling water replenishment, toilet flushing and some other non-domestic water uses. Crop irrigation and groundwater recharge. However, due to the existenc...

Problems solved by technology

[0003] By summarizing the previous community rainwater utilization systems, it is found that there are three main deficiencies: First, the collection and treatment of community rainwater is simply discharged into the urban rainwater pipe through the downpipe, and then flows into the sewage treatment plant together with domestic sewage for treatment
