Does residual chlorine belong to the pollutant control project of urban sewage treatment plants? Residual chlorine means that after chlorine is put into water, in addition to consuming part of the chlorine by the action of bacteria, microorganisms, organic substances, and inorganic substances in the water, there is still a part of chlorine remaining, which is called residual chlorine. Chlorine-containing disinfectants generally refer to disinfectants that dissolve in water to produce hypochlorous acid with microbicidal activity. Drainage units increase the use of chlorine-containing disinfectants, which may lead to higher residual chlorine content in the influent water of urban sewage treatment plants. If urban sewage treatment plants do not take corresponding measures to reduce chlorine, the corresponding residual chlorine content in the effluent will be relatively high. Then, will the high residual chlorine be recognized by the ecological and environmental authorities as the effluent water quality exceeding the standard? 'Pollutant Discharge Standards for Urban Sewage Treatment Plants' (GB 18918-2002) stipulates: According to the source and nature of pollutants, pollutant control items are divided into basic control items (must be implemented, mainly including the impact on water environment and urban sewage treatment General pollutants that can be removed by the general treatment process of the plant, as well as some first-class pollutants, a total of 19 items) and selected control items (by the local environmental protection administrative department according to the category of industrial pollutants accepted by the sewage treatment plant and the water environment quality requirements Selective control, including pollutants with long-term impact on the environment or high toxicity, a total of 43 items). Residual chlorine is not included in the pollutant control items of the above standards. It can be seen that since residual chlorine has not yet been included in the pollutant control items of effluent water quality of urban sewage treatment plants, high residual chlorine content in effluent water from urban sewage treatment plants will not be judged by the ecological environment law enforcement department as effluent water quality exceeding the standard. However, it should be noted that excessive residual chlorine may affect the water quality and ecological environment of the receiving water body effluent from urban sewage treatment plants, and may also lead to liability for environmental pollution damages.
