Background
Water resources are basic natural resources, are one of the control factors of ecological environment, and are strategic economic resources, and are a part of the comprehensive national force development of the country. However, the water resource in China faces serious problems, so that the utilization of the water resource in China is more tense nowadays. The total annual water resource of China is 28124 billions of cubic meters in years and occupies the sixth position in the world, but the water resource quantity owned by people is 2200 cubic meters and is only one fourth of the average water resource level of the world, and the water resource is listed as one of 13 water-poor countries, particularly in the northern and western regions of China, the average water resource occupancy of people is 1127 cubic meters and is only 1/3 of the average water resource occupancy of the southern people. In northern areas, river flow is cut off, underground water is seriously overstrained, and the phenomenon of large-area underground water level decline gradually becomes serious. People in many areas have the problem of difficult water use until now, most of water resources are from rivers, underground water and rainfall, and for western areas, rivers and underground water are used as doctors, and rainwater is a good water resource source, so that the daily water use problem of people can be relieved to a great extent if reasonable collection and purification can be realized.
