The presence of the hazardous microbial species in pond sewage is a serious threat to the aquatic environment and human health, and an effective purification method is urgently needed. Here, we reported the evaluation and purification effect of sewage by a custom-built air surface discharge plasma. Results show that the most sensitive bacterial flora mainly includes Cyanobium, Candidatus, and Proteobacteria, based on inactivation map by the DNA sequence. The inactivation of microbial species by plasma treatment would reach beyond 5-log reduction and the water turbidity would be effectively improved. Identification of the significance of reactive oxygen and nitrogen species with scavengers indicates that the purification effect is closely linked to the key agents ONOO⁻ and H₂O₂. This study would contribute to an in-depth insight into decontamination and provide a potential alternative for sewage purification.

定制空气表面放电等离子体对池塘污水微生物物种灭活和净化的评价

池塘污水中有害微生物种类的存在对水生环境和人类健康构成严重威胁，迫切需要一种有效的净化方法。在这里，我们报告了定制的空气表面放电等离子体对污水的评估和净化效果。结果表明，最敏感的菌群主要包括Cyanobium，暂定和变形菌，基于由所述DNA序列的失活地图。通过等离子体处理对微生物物种的灭活将达到5-log以上的减少，并且水的浊度将得到有效改善。用清除剂鉴定活性氧和氮物质的重要性表明净化效果与关键试剂 ONOO 密切相关^-和H ₂ O ₂。这项研究将有助于深入了解去污，并为污水净化提供潜在的替代方案。
