【摘要】 后疫情时代，新型冠状病毒（SARS-CoV-2）并未被消灭，仍会进入排水系统并带来风险。首先，结合现有研究成果，分析了污水收集系统、污水处理厂和污泥处理系统中病毒的迁移途径，并推断SARS-CoV-2将进入污泥处理系统，必须针对病毒加以应对。其次，分析了现行污泥处理处置标准无害化指标和操作方面要求。第三，分析了疫情期间现有应对措施，并针对污泥处理系统提出4个方面的应对措施建议。最后，强调污泥作为整个排水系统进入环境的最后一个环节，要关注无害化这一根本要务，必须做到处理产物无害化与处理过程无害化“两手抓，两手都要硬”。更多还原

【Abstract】 In post-pandemic, SARS-CoV-2 has not been eliminated and will still enter the drainage system with posing risks. Firstly, based on the existing research results, the migration pathways of SARS-CoV-2 in sewage collection system, sewage treatment plant and sludge disposal system were analyzed. It was considered that SARS-CoV-2 would enter the sludge treatment system, while the virus must be dealt with. Secondly, the harmless indexes and operation requirements of the current sludge treatment and disposal standard are analyzed. Thirdly, the countermeasures existing during the epidemic period were analyzed, and four suggestions were put forward for the sludge treatment system. Finally, it is emphasized that as the last link of the whole drainage system entering the environment, the fundamental task to be paid attention to is sludge harmless. In addition, it is necessary to make the treated products harmless and the treatment process harmless.更多还原
