Sponge city construction rainwater falling water diversion, grading purification and water storage comprehensive utilization system

Abstract

The invention discloses a sponge city construction rainwater falling water diversion, graded purification and water storage comprehensive utilization system which is characterized in that a diversion filtering purification pool (22) is arranged at the lower bottom of one side of a building (18), a sewage interception anti-blocking basket (2) is arranged in a rainwater well, an anti-blocking conical stand column (24) is arranged in the sewage interception anti-blocking basket (2), a filtering purification and infiltration promotion precipitation well (4) is arranged at the lower end of a rainwater collection pipeline (3), and the rainwater collection pipeline (3) is connected with the rainwater collection pipeline (3). The primary seepage purification reservoir (7) and the secondary seepage purification reservoir (11) are arranged at the right end of the rainwater collection pipeline (3) through the purification seepage plate wall (8), the seepage well (12) is arranged at the right lower end of the secondary seepage purification reservoir (11), and water after underground water is supplemented flows into an urban sewer through the public pipe network (14). Due to the fact that urban ecological rainfall flood is subjected to collection, graded purification, storage utilization, underground water source conservation and supplement and discharged to a public pipe network, urban rainfall flood disasters are effectively reduced, the underground water descending momentum is relieved and restrained, and the utilization rate of rainfall flood resources and the urban ecological environment are improved.

Description

Technical field: [0001] The invention relates to a sponge city construction rainwater diversion, graded purification and water storage comprehensive utilization system for collecting and seeping rainwater during the flood season in cities, preventing backflow, preventing mosquitoes and flies, intercepting sewage, purifying and regulating storage, comprehensively utilizing and conserving underground water sources . Background technique: [0002] At present, the existing drainage systems of large and medium-sized cities in my country generally have the problem of poor drainage. Heavy rainstorms will cause urban waterlogging, requiring temporary pumping and drainage, which affects the normal operation of the city and also causes huge economic losses. Especially this year, the central China region of our country has brought continuous strong wind and rain on a large scale, which has caused regional waterlogging and led to waterlogging disasters. The reason is that the ecologic...

At the same time, because there is no water storage facility for a large amount of rainwater when it rains, it is not used in time, which also causes the city's groundwater level to generally drop. When it is dry, it is necessary to use a large amount of water to irrigate the green vegetation, wasting a lot of water resources in vain.
