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.
