Method and system for comprehensively treating typical agricultural non-point source pollution

Abstract

The invention provides a method and system for comprehensively treating typical agricultural non-point source pollution. The method for comprehensively treating the typical agricultural non-point source pollution comprises the steps of controlling an agricultural non-point source pollution source so that initial pollutants form a first treatment substance; ecologically intercepting the first treatment substance to form a second treatment substance; and carrying out ecological remediation on the second treatment substance to form emissions. The system for comprehensively treating the typical agricultural non-point source pollution comprises a pollution source control sub system, an ecological intercepting sub system and an ecological remediation sub system which are arranged in sequence according to the flowing direction of the initial pollutants. According to the method and system provided by the invention, the pollutants are treated with an ecological intercepting method after the agricultural non-point source pollution source is controlled; and finally, end-of-pipe treatment is carried out on the treated pollutants with an ecological remediation method to form integrated organictreatment and comprehensive treatment. The method and system for comprehensively treating the typical agricultural non-point source pollution, provided by the invention, have the advantages that a resource-saving, environmentally-friendly and ecosystem conservation type sustainable agricultural production mode can be established, so that the agricultural non-point source pollution is effectively monitored and treated.

Description

technical field [0001] The invention relates to the technical field of pollution control, in particular to a method and system for comprehensively controlling typical agricultural non-point source pollution. Background technique [0002] Agricultural non-point source pollution refers to dissolved or solid pollutants in agricultural production and life, such as soil particles in farmland, nitrogen, phosphorus, pesticides and heavy metals, rural poultry manure and domestic waste, etc. In a specific area, under the action of precipitation and runoff, a large amount of pollutants enter rivers, lakes, reservoirs, bays and other receiving water bodies through methods such as farmland surface runoff, farmland drainage and underground seepage. [0003] The main manifestations of agricultural non-point source pollution are: farmland non-point source pollution, livestock and poultry breeding pollution, villagers' domestic sewage pollution, surface runoff wastewater pollution, etc. Am...
