摘　　要：高负荷活性污泥法具有矿化率低、初级污泥产量大且产甲烷潜势高等优点,在实现污水厂碳中和、能源自给方面展现出巨大的潜力,引发了对该"过时"工艺的再思考、再探索。在总结高负荷活性污泥法在碳源回收方面的研究基础上,介绍了两种高负荷活性污泥法(传统高负荷活性污泥法、高负荷接触稳定法)的工艺流程及其特点;分析了碳源改向的两种途径--生物絮凝和细胞贮存;总结了泥龄、水力停留时间、溶解氧和污泥浓度等工艺参数对碳源回收率的影响;讨论了高负荷活性污泥法数学模型。提出了尚需解决的问题和发展态势,以期为高负荷活性污泥法的研究、设计、运行和优化等提供参考。High-loaded activated sludge(HRAS) process has advantages of low mineralization efficiency and high primary sludge production with high biochemical methane potential. HRAS exhibits excellent potential for realizing carbon neutrality and energy self-sufficiency in wastewater treatment plants. It is motivated the rethinking and re-exploration of this "old" process. Based on previous works about HRAS, the paper introduced two process types of carbon recovery, which named conventional high-rated activated sludge process(HRCAS) and high-rated contact and stabilization process(HRCS). This paper analyzed two approaches of carbon redirection, bioflocculation and intracellular storage, summarized parameter influences on carbon recovery such as sludge retention time, hydraulic retention time, dissolved oxygen and sludge concentration. It also discussed HRAS mathematical model. It proposed remaining challenges and trends of HRAS for research, design, operating and optimization in future.
