长江经济带典型污水收集系统提质增效量化研究

Quantification of Quality and Efficiency Improvement of Typical Urban Sewage Collection System in Yangtze River Economic Belt

提质增效是城市污水收集系统查漏补缺、提高污水处理厂进水COD浓度、改善运行效能的重要举措。为此,基于城市水系统模型(MIKE+)形成了一套构建城市污水收集系统水动力、水质量化模拟分析的技术方法,并以长江经济带典型污水收集系统为例,建立污水收集系统模型,量化模拟分析了污水提质增效措施对污水处理厂进水COD浓度的改善效果。实践表明,该技术方法具备可复制推广性。

Improving quality and efficiency is an important measure to fill up the gaps of urban sewage collection system, increase the influent COD of sewage treatment plant and improve the operational efficiency. This paper proposed a set of technical methods for establishing quantitative models of hydrodynamics and water quality of urban sewage collection system based on the urban water system model MIKE+. The model of a typical sewage collection system in the Yangtze River economic belt was established, and the improvement effect of sewage quality and efficiency improving measures on influent COD of the sewage treatment plant was quantitatively simulated and analyzed. The practice showed that the method had application potential.
