Resistant pollutants like oil, grease, pharmaceuticals, pesticides, and plastics in wastewater are difficult to be degraded by traditional activated sludge methods. These pollutants are prevalent, posing a great threat to aquatic environments and organisms since they are toxic, resistant to natural biodegradation, and create other serious problems. As a high-efficiency biocatalyst, enzymes are proposed for the treatment of these resistant pollutants. This review focused on the roles and applications of enzymes in wastewater treatment. It discusses the influence of enzyme types and their sources, enzymatic processes in resistant pollutants remediation, identification and ecotoxicity assay of enzymatic transformation products, and typically employed enzymatic wastewater treatment systems. Perspectives on the major challenges and feasible future research directions of enzyme-based wastewater treatment are also proposed.
废水中的油性物质、油脂、药品、农药和塑料等难降解污染物，很难通过传统的活性污泥法进行降解。这些污染物普遍存在，对水生环境和生物构成巨大威胁，因为它们具有毒性、难以自然生物降解，并会造成其他严重问题。酶作为一种高效的生物催化剂，被提议用于处理这些难降解污染物。本综述重点讨论了酶在废水处理中的作用和应用。文中探讨了酶的类型及其来源、酶在难降解污染物修复中的作用过程、酶转化产物的鉴定和生态毒性检测，以及典型的酶法废水处理系统。还提出了基于酶的废水处理所面临的主要挑战和可行的未来研究方向的观点。
