Green building rainwater collecting and discharging system

Abstract

The invention discloses a green building rainwater collecting and discharging system, and relates to the technical field of rainwater collecting devices. The green building rainwater collecting and discharging system comprises a rainwater flow channel, wherein the outlet end of the rainwater flow channel is connected with a flushing water storage pool and a primary filtering water pool; the wateroutlet end of the flushing water storage pool is positioned above the primary filtering water pool; the outlet end of the primary filtering water pool is connected with a rainwater filtering and settling pool, and a rainwater discarding device is arranged between the primary filtering water pool and the rainwater filtering and settling pool; the rainwater discarding device is further connected with the rainwater filtering and settling pool through a rainwater purifying device; and the outlet end of the rainwater filtering and settling pool is connected with a backflow pool, and a plurality ofrainwater collecting pools are arranged between the rainwater filtering and settling pool and the backflow pool. According to the green building rainwater collecting and discharging system, rainwatermetal in the initial stage of rainfall is collected and then treated through the rainwater discarding device, the cost of agent treatment is reduced, and the overall treatment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of rainwater collection devices, in particular to a rainwater collection and discharge system for green buildings. Background technique [0002] With the development of the urbanization process, the accumulation of pollutants has caused a large amount of pollutants to be held in rainwater such as roads and roofs. Studies have shown that the pollution load in the initial 30% rainwater runoff accounts for 70% of the entire rainfall pollution. Therefore, the initial rainwater The interception and treatment can effectively control the water pollution caused by runoff. At present, there are different measures for rainwater pollution treatment, some are directly collecting rainwater for reuse, and some are directly introducing initial rainwater into sewage treatment plants, ignoring the limited decontamination capacity of sewage treatment plants, and the excess sewage is directly discharged into the natural enviro...
