- Abstract:
- During the outbreak of coronavirus pneumonia, chlorinated disinfectants have been usually overused, leading to a massive discharge of residual chlorine into surface water through the wastewater treatment plant effluent, ground wash-out and surface runoff. Residual chlorine can affect the stability of water ecosystem and bring potential risk to water quality of the drinking water resources even at low concentration level. According to the comparison of surface water quality standards and literature researches between domestic and abroad reports, it is considered that residual chlorine has a significant indicator effect on the water ecological environment. So far, monitoring methods of residual chlorine are relatively mature, which could reach the requirements of the conventional water quality monitoring. Thus, monitoring of residual chlorine in drinking water sources is highly recommended to ensure the stability of water ecosystem and the safety of water quality in the future.
