Abstract
In this paper, the impact of non-point source pollution of livestock and poultry farming in mountainous areas on the water environment in mountainous areas is studied, which is in order to provide a scientific basis for the migration control of non-point source pollution and managing the water environment. Concluded as follows: (1) The main pollutants are TN and COD. What’s more, TN, COD, TP and NH4+-N in the East River are insensitive. TN and COD sensitivity of the West River and Baoxing Rriver are mildly sensitive and TP and NH4+-N is insensitive. (2) The risk sources of East River, West River and Baoxing River are explored. According to 4R control technology of non-point source pollution, source reduction, process interruption, recycling and ecological restoration should be strengthened. Therefore, this study diagnoses the main pollutants and identifies the sources of risk and provides a scientific basis for effective control measures.
