摘要

水分配网络由回用、再生和废水处理3个相互作用的子系统构成。设计水分配网络需考虑质量负荷固定和流量固定两类用水操作模型。目前，兼顾两类用水操作的图形方法对水分配网络的研究局限于一个或两个子系统的设计，而缺少一种能同时处理3个子系统的方法。本文用新的方法合成了反映用水网络水源盈亏情况的总组合曲线，并由此得到最小废水量和新鲜水量。为考虑废水再生情况，提出通过用再生水线和废水线合成废水排放线的方法求解再生情况下的最小新鲜水量。同时，根据总组合曲线得到了废水组合曲线，求得最小废水处理量。实例表明，本文所提方法可在具体网络设计前，在同一浓度-质量负荷图中确定单杂质水分配网络的各目标参数，且简便易行。

Abstract

This paper presents a new approach to targeting minimum freshwater and minimum effluent treatment flow rates of a water allocation network.A grand composite curve based on the concept of Wang and Smith’s limiting composite curve was constructed firstly to determine the waste water line with minimum flow rate.Then

the waste water line was modified for the case of regeneration-reuse.The minimum treatment target was obtained through a waste water composite curve

which was generated from the grand composite curve.The proposed approach could be applied to the fixed flow rate as well as the fixed contaminant load problems with a single contaminant.Finally

the reuse

regeneration-reuse and waste water treatment problems could be solved in a single concentration versus contaminant load diagram.
