【摘要】 本研究对辽宁省大伙房水源保护区氮、磷污染的现状及氮、磷污染物的来源进行了分析。研究发现,工农业生产以及库区居民生活所带来的点源、面源污染,是氮、磷污染物的主要来源;此外,燃煤及机动车尾气氮氧化合物的排放,水库底泥中氮、磷化合物对水体的二次污染,是水库水体中氮、磷指标偏高的重要影响因素。研究总结了氮、磷污染物防治的法规建设,提出了点源、面源污染和间接污染的防治措施以及水体修复的措施,为辽宁大伙房水库的保护和水源地建设提供了参考。更多还原

【Abstract】 This research is conducted to analyze the current situation of nitrogen and phosphorus pollution in Dahuofang water conservation district of Liaoning Province. In this study, it is found that the point source and non-point source pollution from industrial and agricultural production and residents’ life in reservoir area is the main source of nitrogen and phosphorus pollution.In addition, coal combustion and vehicle exhaust NOx emissions, nitrogen and phosphorus compounds in the reservoir sediment to water secondary pollution are important factors that cause a higher index of nitrogen and phosphorus of reservoir water. Studying the prevention of nitrogen and phosphorus, presenting prevention and water resumptive measures of the point source, non-point source and indirect pollution, provide a reference for Liaoning Dahuofang reservoir protection and water source construction.更多还原
