- 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.
