水环境容量计算在污水系统规划中的应用

在污水系统规划中,扩大规模需要考虑纳污河流的环境承载力。利用一维水环境模型,计算了DQ县两纳污河流的水环境容量。结果表明,当前的环境剩余容量无法满足污水系统中远期规划的要求,上游来水断面的污染物浓度是提高剩余环境容量的重要约束条件。污水系统规模的扩大需要在改善现有水环境的条件下进行。

Application of Water Environmental Capacity Calculation to Sewage System Planning

In expanding planning of sewage system,the environmental capacity of related river should be taken into consideration.The water environmental capacity of the two rivers in DQ County was calculated using 1-D water quality model.The results indicated that the current surplus environmental capacity could not meet the requirement of the long-term sewage planning.The pollutant concentration in upstream water was an important constraint for increasing the surplus environmental capacity.The current water environment should be improved to expand the capacity of sewage system.
