摘要
水环境容量的确定是实行区域水环境管理的基础及水污染物总量控制的依据。本文以氨氮和COD为指标,测算了江西五大水系的水环境容量,并与根据定额法预测的指标排放量比较,分析了其水污染总量控制情况。结果为:①总体上目前五大水系的水质良好,大部分河段存在剩余水环境容量;②个别河段水污染严重,氨氮容量值为0,需加强该区段的污染控制力度;③随着人口增长及社会经济的发展,将来在总量上需要实行严格的污染物(尤其对COD)削减计划。
It is the foundation to identify regional Water Environmental Capacity（WEC） Sor implementing regional water environmental management and the basis of total water pollution control. So, the WEC of the five water systems in Jiangxi was computed by using the two indicators of NH3-N and COD. Then, we compared it with the acceptable prediction indicators and analyzed its total control situation of water pollution. The results are： firstly, the current water quality of the five water systems was good in general, most of the rivers＇ sections have residual WEC, sec- ondly, only individual river＇s sections have the serious water pollution and its capacity of NH3-N is 0, so it is necessary to strengthen the pollution control of this section and lastly, with the pop- ulation growth and socio-economic development, it is necessary for the five water systems to carry out strick total pollution reduction plans （especially for COD） in future.
