Abstract

A huge rainwater-collecting system is provided. It contains rainwater-collecting pipe, groundwater storage, impounded basin, anchor gate, sand sluicing canal, receiving canal, de-silting basin, sand-extracting pump and water-extracting pump. Anchor gate is set on outer wall of impounded basin. Rainwater-collecting pipes connect with impounded basin and de-silting basin. Several short walls are set on back plane of impounded basin to divide it into some sand sluicing canals. Receiving canal is set on end of sand sluicing canal. Receiving canal connects with all sand sluicing canals and expands to de-silting basin. Pumps connects de-silting basin. The second programme, sand-extracting pump is fit on bottom of de-silting basin. Water-extracting pump is fit on the part that is higher than bottom.

Description

technical field [0001] The invention relates to a device in the technical field of water conservancy engineering, in particular to a large-scale rainwater collection and treatment system device. Background technique [0002] my country's water resources are seriously insufficient. my country's per capita water resources are less than 2,200 cubic meters, less than one-third of the world's average, and only 990 cubic meters in the northern region, less than one-eighth of the world's average. Severe water pollution has exacerbated the shortage of water resources. At present, the national water shortage in normal years is nearly 40 billion cubic meters, of which about 30 billion cubic meters are lacking in irrigation areas. An effective rainwater collection system is the need for the sustainable development of the country's economic construction. Rainwater harvesting for drinking, gardening, and other domestic purposes is now found in new urban developments. The collected rain...
