摘要

分布式废水处理系统集成的本质特征之一是通过最大程度减少不必要的水流混合量而降低系统的总处理量。根据这一思想

提出了一种基于启发式规则的方法设计废水处理单元有最大入口浓度限制的单杂质废水处理系统。首先依据提出的规则确定处理单元的执行顺序

并在此基础上建立初始网络结构;然后通过计算确定最终网络结构。在设计过程中

上述规则的运用和最终网络结构的确定需要与杂质负荷平衡、夹点确定等废水处理网络设计的基本概念以及入口浓度限制条件相结合。对文献实例的研究表明

结果与数学规划法的求解结果相当

但设计过程更为简单且具有明确的工程意义。

Abstract

One of the important essences of distributed wastewater treatment system integration is to reduce the total treatment flow rate by lowering unnecessary stream mixing amount as much as possible. Based on this insight

a heuristic method is presented for design of distributed wastewater treatment network (WTN) of single contaminant with maximum inlet concentration constraints. Firstly

an initial network is developed based on the precedence order of treatment units and the allocation of streams to treatment units obtained by using the heuristic rules proposed. The final design can then be obtained with mass and flow rate balances. In the design procedure

the following factors will be used simultaneously: heuristic rules proposed

mass and flow rate balances

determination of the pinch point and maximum inlet concentration constraints. The results of a few literature examples show that the designs obtained with the proposed method are comparable to that obtained with mathematical programming approach. However

the proposed method is simple and of clear engineering insight.
