江苏省灌河流域污染特征及污染控制对策

基于2008年江苏省沿海地区灌河流域各城市污染源统计及调查数据,分析灌河流域主要污染物来源构成和污染特征,对污染物入河量进行计算及修正.结果表明:灌河的CODMn入河总量为36944.2 t/a,氨氮入河总量为4366.5 t/a,总氮和总磷入河总量分别为6507.4 t/a、444.6 t/a,各污染源均主要来源于农业污染.同时,针对灌河流域的污染特征,明确各类污染源的治理重点,提出了污染控制对策,为有效保护灌河水环境质量,支撑灌河口和灌河沿线的开发提供依据.

Characteristics of pollutant sources and control measures in Guanhe River Basin, Jiangsu Province

Based on municipal pollutant sources data of Jiangsu coastal area in 2008, the main pollutant source composition and pollution characteristics of Guanhe River, the total amount of pollutants into the river was calculated and corrected. Results showed that the total input amount of chemical oxygen demand, ammonia nitrogen, total nitrogen and total phosphorus to Guanhe River was 36944.2, 4366.5, 6507.4 and 444.6 t/a, respectively, all of which were mostly originated from agricultural pollution. According to the pollution characteristics of Guanhe River, various pollution sources were clarified. Therefore we put forward countermeasures to control the pollution, which provide a foundation for effectively protecting the Guanhe River water quality and supporting the development of the region.
