摘　　要：城镇供水末端普遍存在水质变差、余氯不达标等问题。在二次供水处进行加氯消毒是改善末端水质、为用户龙头水提供安全保障的有效途径。基于此,开发了智能二次供水加氯消毒系统,以银川市某小区二次供水为研究对象,分析其用水特性,并采用相应的投加模式,检测系统运行的投加和用户龙头水余氯控制效果。基于增量式PID控制算法,采用开环控制前馈投加与闭环控制反馈调节相结合的复合环控制,将整个系统离散化控制以便达到适应水质、水量的变化,实现动态调整投加,从而精准控制水中余氯浓度。There are widespread problems at the end of urban water supply,such as poor water quality and insufficient residual chlorine.Chlorination in secondary water supply is an effective way to improve the end water quality and ensure the safety of user’s tap water.This paper developed an intelligent secondary water supply chlorination system and applied it in a community in Yinchuan City.The water consumption characteristics were analyzed,and the corresponding dosing mode was adopted to investigate the operation of the dosing system and the control of residual chlorine in user’s tap water.Based on the incremental PID control algorithm,the composite loop control integrated open loop feedforward control dosing and closed loop control feedback regulation was adopted to discretize the whole system to adapt to the changes in water quality and quantity,and realized the dynamic adjustment dosing,so as to accurately control the residual chlorine concnetration in water.
