摘　　要：根据消毒剂种类及位置的选择,介绍了水厂一级消毒工艺的优化情况,从安全性和效果方面研究了次氯酸钠和硫酸铵替代液氯、液氨的可行性。考虑城镇化的发展和供水管网的扩张,阐述了管网二级消毒工艺的必要性和运行情况。基于郊区集约化供水系统的特点,提出终端消毒的设想,并建议在区域供水规划和设计之初,着眼于水厂、管网和用户组成的整个供水系统,引入多级消毒的理念。According to the types of disinfectants and their dosing position, the optimization of one-stage disinfection process in waterworks was introduced. The feasibility of dosing sodium hypoehlorite and ammonium sulfate instead of liquid chlorine and liquid ammonia was studied for safety and efficacy. Considering the development of urbanization and the expansion of water supply network, the necessity and operation of network two-stage disinfection process were expounded. Based on the characteristic of intensive water supply system, the idea of terminal disinfection was proposed, and it was suggested that the concept of multi-stage disinfection could be used at the beginning of regional water supply planning and design, focusing on the whole water supply system composed of waterworks, network and users.
