Sponge community rainwater comprehensive utilization system and utilization method

Abstract

The invention discloses a sponge community rainwater comprehensive utilization system which comprises a hydrocone type roof rainwater collecting system, a main rainwater pipe network, an initial rainwater storage tank, a rainwater storage pool and a pumping water pump. The sponge community rainwater comprehensive utilization system is characterized in that the initial rainwater storage tank and an underground regulating pool are arranged over and under the ground respectively, and under the action that rainwater flows into a regulating mechanism, initial rainwater flowing through a water collecting pipe can flow into the initial rainwater storage tank, and later rainwater is drained into the rainwater storage pool through a water outlet pipe. A rainwater utilization method comprises the steps of collecting the initial rainwater on the roof, collecting the initial rainwater on the ground, distributing and purifying the initial rainwater, settling the initial rainwater, overflowing the rainwater, utilizing the initial rainwater, reusing the rainwater in the rainwater storage pool and collecting greenbelt seepage water. According to the rainwater comprehensive utilization system and method, when the initial rainwater storage tank is full of the water, the later rainwater directly flows into the underground rainwater storage pool, therefore, separating and distributing processing and utilizing of the initial rainwater and the later rainwater are achieved, the beneficial effect is significant, and application and popularization are convenient.

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
