- 摘要:
- 针对近年来管网消毒技术产生的消毒副产物（DBPs）日益突出进而影响饮用水水质的问题，研究了管网DBPs的生成原理、常见消毒技术的特点以及对应生成DBPs的情况，并从管材和生物膜两方面总结了管网中影响DBPs生成和迁移转化的典型因素，从源头水厂消毒、管网维护、精准补氯、改进消毒技术等方面提出了控制管网DBPs生成和转化的运行管理建议，以及构建完善的管网饮用水去除DBPs体系，以期为提高二次供水水质提供借鉴。
- Abstract:
- The disinfection by?products (DBPs) generated by the pipe network disinfection technology have become increasingly prominent in recent years, which seriously affect the quality of drinking water. To solve the above problem, the principle of generating DBPs in pipe networks, the current application status of common disinfection technologies, technical characteristics, and the corresponding situation of generating DBPs are studied. The typical factors affecting the generation and migration of DBPs in the pipe network are summarized from the aspects of pipes materials and biofilms. The control method of the generation and transformation of DBPs in the pipe network is proposed from the source water plant disinfection, pipe network maintenance, precision chlorine supplement, and improved disinfection technologies. It is recommended to build a complete pipe network to remove DBPs in drinking water management, which can provide a reference for improving the quality of secondary water supply.
