导致河道水中氨氮和总磷超标的主要污染物成因及防治探析

Cause and control of main pollutants that lead to ammonia and total phosphorus exceeding standard in river water

目前我国河水氨氮、磷超标问题较为普及,尤其是经济欠发达的城市,水污染与畜禽养殖业等外源因素,以及氮磷物质进入水中发生富营养化等内源因素有关。如何采取有效措施防治水中氨氮、磷超标,确保水环境健康发展已成为当前水质监管等部门急需解决的问题。

At present, the problem of ammonia nitrogen and phosphorus exceeding the standard is more popular in our country, especially in the less developed cities. The cause of water pollution is related to the exogenous factors of livestock and poultry breeding, as well as the endogenous factors such as the eutrophication of nitrogen and phosphorus substances into the water. How to take effective measures to prevent and control the water quality of ammonia nitrogen and phosphorus to ensure the healthy development of water environment has become a problem urgently needed to be solved by the relevant departments of water quality supervision and control.
