摘　　要：建立了基于最大日负荷量(TMDL)的九洲江流域水污染控制模式,利用负荷历时曲线法计算了流域允许负荷。通过对流域点源和非点源污染负荷估算,明确了九洲江流域COD、氨氮和总磷的污染负荷削减比例,并提出较为具体的污染控制措施。结果表明,九洲江流域主要污染物COD、氨氮、总磷的实际负荷超出允许负荷,其负荷削减比例分别达到30.12%、29.58%和33.62%,且畜禽养殖和生活污染源是主要的污染源,须采取有效措施进行污染负荷削减。A water pollution control model based on total maximum daily load(TMDL)was developed in this paper.According to the hydrological and water quality data,load duration curve method was used to calculate the permitted load of COD,ammonia nitrogen and TP.Then,through the estimation of the present point source and non-point source pollution load,pollution reduction rate were clearly determined and pollution control measures eventually put forward.The results showed that permitted load of COD,ammonia nitrogen and TP was below the actual load.The pollution reduction rate of COD,ammonia nitrogen and TP reached up to 30.12%,29.58%and 33.62%respectively.Particularly,livestock farming and domestic pollution sources were the main sources of pollution.It is necessary effective measures for reduction of pollution load.
