Description
Technical Field
The invention relates to the technical field of water pollution treatment, in particular to a regional water body pollution treatment method.
Background
Water body refers to a natural complex that is a segment covered by water. It not only includes water, but also includes dissolved matter, suspended matter, bottom mud, aquatic organism, etc. according to the position of water body, it can be roughly divided into three types of ground water body, underground water body and sea, etc. which 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. Because the mode of excessively exploiting underground water and using water falls behind in China, the water resource crisis is deepened continuously and the water shortage in agriculture and cities is serious due to the amazing waste of water resources and the aggravation of water pollution: the water shortage of the agriculture reaches 300 billion cubic meters every year, the drought area is about 2000 hectares, and 8000 ten thousand rural population drinking water is difficult; in cities, 154 cities had water shortage in 1979, 188 cities had water shortage in 1984, and more than 300 cities had water shortage in 1991. According to statistics, the national tap water supply capacity can only guarantee 86% of the peak water demand on average. Therefore, although water is a renewable resource, water is not inexhaustible and is available for human use, and the national industrial production is lost by hundreds of billions of yuan each year due to water shortage.
The water body pollution mainly refers to the phenomenon that pollutants discharged by human activities enter a water body to cause water quality reduction and reduction or loss of utilization value. There are two types of causes of water contamination strictly: one is caused by human factors and mainly is industrial discharged wastewater. In addition, the method also comprises domestic sewage, farmland drainage, pollutants in rainfall elution atmosphere, pollutants in the water body which is eluted by garbage accumulated on the ground through rainfall, and the like; in addition, the water body pollution caused by natural factors, such as weathering and hydrolysis of rocks, volcanic eruption, erosion of the ground by water flow and precipitation and leaching for atmospheric dust fall, also exists. The release of substances by organisms (mainly green plants) in the geochemical cycle is a source of natural pollutants. Since the water pollution caused by human factors is the majority, the water pollution is mainly the pollution caused by human factors.

Therefore, the technical scheme realizes the gradual realization of the self-purification capacity of the water body by establishing a stable water body ecological system by utilizing the food chain principle of animals and plants in the water body, but the scheme is suitable for ecological restoration of the polluted water body, and for the water body with continuous sewage discharge, the problem of the over-limit sewage purification capacity can not be realized due to the limitation of the self-purification capacity of the water body, meanwhile, as the composition and the quantity of the animals and plants in the water body ecological system have stability within a certain time period, when the pollutant components or the concentration of the sewage discharged from the water body change, the due purification capacity can not be reached according to the sewage treatment requirement, the continuous accumulation of pollution conditions can be caused, the water body ecological system is damaged again, and in the severe environment such as winter, the purification capacity of animals and plants in a water body ecological system is reduced due to seasonal influence, and if the self-purification capacity of the water body is completely depended on, the problem that pollutants in the water body are enriched due to the insufficient purification capacity of the water body is easily caused.
