供水管网水质模型中余氯在主体水中的衰减情况分析

摘要

在供水管网中,影响余氯消耗的因素有很多,本文主要研究影响余氯在主体水中衰减的因素.通过研究发现,主体水中pH的变化对余氯衰减速率常数( kb )的影响不大,而随着温度( t)、初始氯质量浓度( C0 )以及有机物质量浓度( TOC)的变化,kb 均有显著变化,这些变化可以用一级反应动力学模型模拟出来,并建立主体水余氯衰减水质模型.将模型应用于实际管网中,可增强模型的实用性.%Consumption of residual chlorine in water supply network under the influence of many factors, this paper studies the main body of affect residual chlorine water attenuation factor. Through the study found that the main body of water residual chlorine decay rate constant( kb) , temperature( t) , initial chloride mass concentrations( C0) and organic compound concentration( TOC) have significant changes, these changes can be simulated using the first order reaction kinetics model, and establish the main body of water residual chlorine decay water quality model. The model is applied to the actual network, can enhance the practicability of the model.
