摘要 为探索适合非点源污染河流水环境容量计算的模型,为水环境容量的合理利用提供科学依据,针对中国东部地区典型河流—曹娥江的污染情况,选其上游以非点源污染为主的支流进行了水环境容量研究。根据该河段的水流特性和水文、污染源的调查资料及水质实测资料,选用适当的数学模型,研究了该河段各月的水环境容量。结果表明这种方法简单、实用,适用于非点源情形下河流氨氮、总磷及CODcr的容量问题研究。 In order to explore math model for the water environmental capacity in nonpoint source polluted river and provide scientific basis for the rational use,the water environmental capacity in branch of Nonpoint Source Polluted River was studied,according to the pollution status of the typical river in the east of China-Cao ' e River,Based on the flow characteristics and data of hydrological and pollution sources investigating and water quality data,water environmental capacity of every month was evaluated by using appropriate math model.The results showed that this method was simple,practical and applicable to the case of nonpoint source polluted river for studying water environmental capacity of NH 4 +-N,TP and CODcr.
