Abstract

Activated sludge has a high diversity of infectious agents. However, many of these microorganisms contribute greatly to the biological treatment process due to the enzyme production and capability for degrading a wide range of organic compounds in wastewater. The present review discusses the potential of aerobic granular sludge as a bio-startup (AGS-BS-up) for new wastewater treatment plants. The complex microbial community in activated sludge was investigated using 16S metagenomic analysis. The potential of aerobic granular sludge prepared from activated sludge to be used as a bio-starting medium for food wastewater treatment plants (FWWTP) was discussed. AGS-BS-up appears to have high applicability to enhance the biological treatment of food wastewater (FWW). The hypothesis behind using aerobic granular sludge as a bio-startup for FWWTP lies in the high microbial biodiversity in the aerobic granular sludge, which contributes effectively to the biological treatment of food wastewater. Based on the previous studies, the AGS-BS-up is efficient in improving the quality of FWW to meet international standards required for safe disposal into the environment.

好氧颗粒污泥中复杂微生物群落作为下一代污水处理生物启动方法的潜力

活性污泥中的感染物种类繁多。然而，这些微生物中有许多都能产生酶，并具有降解废水中多种有机化合物的能力，因而对生物处理过程做出了巨大贡献。本综述讨论了好氧颗粒污泥作为新污水处理厂生物启动器（AGS-BS-up）的潜力。采用 16S 元基因组分析法研究了活性污泥中复杂的微生物群落。讨论了从活性污泥制备的好氧颗粒污泥用作食品污水处理厂（FWWTP）生物启动介质的潜力。AGS-BS-up似乎在加强食品废水（FWW）的生物处理方面具有很高的适用性。将好氧颗粒污泥用作食品废水处理厂生物启动介质的理论依据在于好氧颗粒污泥中微生物的生物多样性很高，可有效促进食品废水的生物处理。根据之前的研究，AGS-BS-up 能有效改善食品污水的质量，使其达到安全处置到环境中的国际标准。
