Abstract
The invention provides a rainwater regulating and storing system for sponge city construction. The system comprises an initial rainwater regulating and storing pond part, an ecological soil purifying system part and a rainwater utilization regulating and storing pond part, wherein the ecological soil purifying system is arranged between an initial rainwater regulating and storing pond and a rainwater utilization regulating and storing pond. The initial rainwater regulating and storing pond part comprises the initial rainwater regulating and storing pond, a water inlet pipe, a secondary residue blocking layer, a retention wall, a bottom water passing hole, a rainwater elevating pump, a first liquid level switch, a clearing manhole, a first equipment access hole and a first blow-down pipe. The ecological soil purifying system part comprises a planting soil layer, an ecological filter layer, a soil purifying layer, a thick gravel filtering layer, a clay-bentonite layer, and an HDPE seepage-proofing layer, which are arranged from top to bottom successfully. The rainwater utilization regulating and storing pond part comprises the rainwater utilization regulating and storing pond, a rainwater reuse water pump, a second liquid level switch, a second blow-down pipe, a rainwater reuse pipe, a second equipment access hole, a water meter, an overflow pipe, a second check valve and a second valve. The system is small in occupation area and great in water-holding capacity.
Description
technical field [0001] The invention relates to a rainwater regulation and storage system for sponge city construction, which belongs to the field of water treatment applications. Background technique [0002] Rainwater storage and reuse in the construction of sponge cities belongs to the field of water treatment technology. Rainwater storage and utilization are important links in the construction of sponge cities. It is an important embodiment of the transformation of "combining discharge and storage, focusing on storage". Direct use of rainwater can collect rainwater runoff, and then be used for users after appropriate treatment according to the water quality requirements of users; indirect use of rainwater can take various measures to strengthen rainwater infiltration and replenish groundwater. [0003] Increasing income and reducing expenditure is an effective way to alleviate the shortage of water resources. Rainwater is an important water resource. After rainwater is ...
