Abstract: Urban wastewater treatment plants can be a potential source of resource, energy, and water. How to maximize the realization of resource and energy recovery, water recycling and being environment-friendly, has become the leading development direction of urban wastewater treatment. In order to promote the practices of wastewater resources and energy utilization, and improve its technical level, China Urban Water Association released the Technical Specification for Resource and Energy Recovery from Municipal Wastewater in July 2023. The technical specification, for the first time in China, put forward the technical route, parameters, and operation and management points in wastewater resources and energy recovery, which can provide guidance for the selection of treatment technology or process, engineering design, and operation optimization. The implementation of this technical specification is of positive significance for realizing the transformation of wastewater treatment plants into resource and energy plants and promoting the green, low-carbon, and high-quality development of urban wastewater treatment in China.
