  • 摘要:基于碳中和背景及污水处理可持续、低碳运行理念,分析了我国污水处理厂不同水质、工艺类型、规模等条件下的能源消耗及能源回收特点,提出了以“碳改向技术+低耗高效复合脱氮技术+污泥厌氧共消化技术+污水热能回收技术+节能降耗技术”的污水处理新模式是实现 我国能源自给型污水处理厂的关键,并提出我国污水处理厂实现碳中和应分为“完全能源自给”及“能源供应工厂”两个目标.此外,对基于此背景下建设的北京某再生水厂的理论能源自给情况进行了分析,结果表明,通过节能降耗、引入外源有机物、污水源热泵回收等措施,北京 某再生水厂能源自给率由12.2%分别提高至17.1%、21.6%、84.7%.
  • Abstract:Based on the background of carbon neutrality and the concept of sustainable development and low carbon operation of sewage treatment, a new sewage treatment mode is proposed by analyzing the characteristics of water quality, treatment process and scale of sewage treatment in China, which is "carbon redirection technology+efficient denitrification technology+sewage sludge co-digestion technology+heat recovery technology+energy saving and consumption reducing technology", otherwise, the carbon neutral of sewage treatment plant in China should be divided into two objectives:fully energy self-sufficiency and energy supply plant. As the engineering practice of this new mode, this paper explores the theoretical energy self-sufficiency of a reclaimed water plant in Beijing. After implementing energy saving and consumption reduction, exogenic organic matter recovery technology of sewage source heat pump,energy self-sufficiency rate of this reclaimed water plant in Beijing increased from 12.2% to17.1%,21.6%,84.7% respectively .
