- Abstract:
- Since its promulgation, the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) has effectively promoted the construction and operation of wastewater treatment facilities, playing a significant role in improving water environment quality. However, during the implementation of the standard, issues have arisen, including the failure of its graded standards due to “one-size-fits-all” enforcement, deviations in sampling and evaluation practices, and hidden risks such as increased carbon emissions and hazardous disinfection byproducts caused by excessively stringent requirements. This paper focuses on how to scientifically leverage the role of the standard. It proposes enhancing its scientific implementation in four key aspects: strengthening the graded discharge standard system, relaxing emission limits for microbial indicators, clarifying the sampling and evaluation system, and embedding carbon emission accounting alongside resource-oriented approaches. These improvements aim to better align with the practical needs of China’s water environment management and promote the high-quality development of the urban drainage sector.
