Rainwater Comprehensive Utilization System and Utilization Method in Sponge Community

Abstract

The rainwater comprehensive utilization system of the sponge community of the present invention includes a siphon type roof rainwater collection system, a main rainwater pipe network, an initial rainwater storage tank, a rain storage pool and a pumping water pump, and is characterized in that an initial rainwater storage tank and an initial rainwater storage tank are respectively arranged above and below the ground In the underground regulating tank, under the action of the rainwater flow adjustment mechanism, the initial rainwater flowing in from the water collecting pipe can flow into the initial rainwater storage tank, and the later rainwater is discharged into the rain storage tank through the outlet pipe. The rainwater utilization method of the present invention includes: a). Initial rainwater collection on the roof; b). Initial rainwater collection on the ground; c). Initial rainwater diversion and purification; d). Initial rainwater settlement; e). Rainwater overflow; f) . Utilization of initial rainwater; g). Reuse of rainwater in rain storage tanks; h). Collection of green land seepage. In the rainwater comprehensive utilization system and method of the present invention, when the initial rainwater storage tank is full of water, the later rainwater directly flows into the underground rain storage tank, realizing the separation, diversion, treatment and utilization of the initial rainwater and the later rainwater, with significant beneficial effects and easy popularization and application.

Description

technical field [0001] The present invention relates to a rainwater comprehensive utilization system and utilization method of a sponge community, and more specifically, to a rainwater comprehensive utilization system and utilization method of a sponge community which can separately treat initial rainwater and late rainwater. Background technique [0002] Water is the source of life. Driven by people's pursuit of economic growth and comfortable life, the consumption of water resources (especially fresh water resources) on the earth is increasing day by day. Fresh water resources are non-renewable resources. Saving and rational use of water resources is not only related to The country's sustainable economic development and social stability are closely related, and are closely related to the daily life of every citizen. The rational use and conservation of water resources not only rely on the macro policy guidelines formulated by the state to realize the rational distribution ...

Problems solved by technology

Although there are devices for collecting rainwater on the roof, none of them have treated the initial rainwater. The concentration of pollutants and particulate matter in the initial rainwater is high, which is close to domestic sewage. It cannot be directly recycled as reclaimed water, nor can it be directly used for flushing. Toilets, pavement sprinkling
