摘　　要：为研究布尔哈通河水质现状,该试验采用单因子指数法结合QUAL2K水质模型,针对布尔哈通河污染物主要来源进行情景模拟并提出污染治理建议。试验结果表明:布尔哈通河干流总磷(TP)和氨氮(NH_(3)-N)未超标,高锰酸盐指数(COD_(Mn))和五日生化需氧量(BOD_(5))指标超标30%,总氮(TN)指标超标70%,主要污染因子为TN,布尔哈通河下游TN污染严重,延吉市污水处理厂(简称“延吉污”)是主要污染源之一。可通过减少TN的排放和引水冲污来改善TN超标的问题,建议延吉市污水处理厂将TN去除率提高至80%,同时增加朝阳河上游水库的放流量,7月份无需增加放流量,4月份需增加放流7 m^(3)/s。结合实际污染情况,可采取减少污水排放量和增加水量的污染治理方案。该文以期为缓解布尔哈通河水质恶化和改善流域水生态环境提供科学依据。In order to study the water quality status of Buerhatong River,the experiment adopted the single factor index method combined with the QUAL2K water quality model to simulate the main sources of pollutants in Buerhatong River and put forward suggestions for pollution control.The results showed that the total phosphorus(TP)and ammonia nitrogen(NH_(3)-N)in the main stream of Buerhatong River did not exceed the standard,the permanganate index(COD_(Mn))and the five-day biochemical oxygen demand(BOD_(5))exceeded the standard by 30%,and the total nitrogen(TN)index exceeded the standard by 70%.The main pollution factor was TN,and the TN pollution in the downstream of Buerhatong River was serious.Yanji Sewage Treatment Plant(referred to as“Yanji pollution”)was one of the main pollution sources.The problem of TN exceeding the standard can be improved by reducing the discharge of TN and diverting water to flush the sewage.It is suggested that Yanji Sewage Treatment Plant should increase the TN removal rate to 80%,and at the same time increase the discharge of the upstream reservoir of Chaoyang River,and there is no need to increase the discharge in July,and 7 m^(3)/s should be increased in April.Combined with the actual pollution situation,pollution control programs that reduce the discharge of sewage and increase water volume might be adopted.This paper aims to provide scientific basis for alleviating the deterioration of water quality of the Buerhatong River and improving the water ecological environment of the basin.
