摘要
在对北京怀沙河的水质进行调查的基础上提出相应的防治对策。结果表明:怀沙河水质已重度富营养化,主要污染物为总氮、总磷,大部分河段总氮质量浓度严重超过Ⅴ类水环境标准,总磷质量浓度超过Ⅲ类水环境标准,综合评价整个流域,水环境为劣Ⅴ类,水资源质量属重富营型,远未达到规划要求的Ⅱ类水环境标准。提出的相应治理对策有:继续加大水环境保护及治理措施;加大清洁小流域建设力度;对潜在的污染因素及早发现,及早治理;采取严格的管理措施;加大水环境保护法规的宣传,提高群众环境保护意识;加大执法力度,提高违法成本,对违法水案件进行严查;加强水质监测和管护工作。该成果对建设清洁型小流域具有参考意义。
The water quality in Huaisha River was investigated and corresponding countermeasures were proposed.Results showed that the water of Huaisha River has been severely eutrophicated.The main pollutants are TN and TP.In most sections,TN is much higher than grade Ⅴ standard of water environment,and TP is higher than Ⅲ class standard.Water environment of the river basin on the whole is evaluated as Ⅴ standard,and the quality of water resources is severely eutrophicated,far from reaching the second class standard of water environment planning requirements.The corresponding countermeasures are put forward：to continue the environment protection and control measures; to increase the construction of clean small watersheds; to detect in time the potential factors of pollution; to take strict management measures; to increase publicity of water environment protection laws and regulations,raising public awareness of environmental protection; to strengthen law enforcement efforts,increasing the cost of law breaking; and to strengthen water quality monitoring and protection work.The result has significant value of reference to the construction of small clean watersheds.
