The water body refers to a natural complex of the section covered by water. The water treatment device not only comprises water, but also comprises water dissolved substances, suspended matters, bottom mud, aquatic organisms and the like, and can be roughly divided into three types of ground water bodies, underground water bodies, oceans and the like according to the position of the water body, wherein the three types of water bodies can be mutually converted. Under the action of solar energy and earth surface heat energy, water is continuously circulated among different water bodies through the tri-state change of the water. The water resource crisis is continuously deepened due to the lag of the way of excessively exploiting underground water and water, the remarkable waste of water resources and the aggravation of water pollution, and the water shortage of agriculture and cities is serious: the water shortage of agriculture reaches 300 hundred million cubic meters each year, the drought area is about 2000 ten thousand hectares, and 8000 ten thousand rural people have difficulty in drinking water; in the city, 154 cities in 1979 lack water, 188 cities in 1984 lack water, and more than 300 cities in 1991 lack water. The statistics show that the national water supply capacity of tap water can only ensure 86% of the peak water demand on average. Therefore, although water is a renewable resource, it is not inexhaustible and available for human use is limited, and annual industrial production losses of several billion yuan are incurred due to lack of water.
The water pollution mainly refers to the phenomenon that pollutants discharged by human activities enter the water body to cause water quality to be reduced and utilization value to be reduced or lost. There are strictly two types of pollution causes of water: one type is caused by human factors, mainly waste water discharged by industry. In addition, the method also comprises the steps of domestic sewage, farmland drainage, leaching pollutants in the atmosphere by rainfall, leaching pollutants in the water body from garbage deposited on the ground by rainfall, and the like; in addition, water pollution caused by natural factors, such as weathering and hydrolysis of rock, volcanic eruption, water flow erosion of the ground, precipitation leaching of atmospheric dust fall. Biological (mainly green plants) release substances in the geochemical cycle all belong to the source of natural pollutants. Since water pollution caused by human factors is the majority, so-called water pollution is mainly pollution caused by human factors.
