Direct municipal wastewater effluent discharge from treatment plants has been identified as the major source of endocrine-disrupting chemicals (EDC) in freshwaters. Consequently, efficient elimination of EDC in wastewater is significant to good water quality. However, conventional wastewater treatment approaches have been deficient in the complete removal of these contaminants. Hence, the exploration of new and more efficient methods for elimination of EDC in wastewater is imperative. Enzymatic treatment approach has been suggested as a suitable option. Nonetheless, ligninolytic enzymes seem to be the most promising group of enzymes for EDC elimination, perhaps, owing to their unique catalytic properties and characteristic high redox potentials for oxidation of a wide spectrum of organic compounds. Therefore, this paper discusses the potential of some ligninolytic enzymes (laccase, manganese peroxidase, and versatile peroxidase) in the elimination of EDC in wastewater and proposes a new scheme of wastewater treatment process for EDC removal.
直接将城市污水处理厂的污水排放到淡水中已被确定为内分泌干扰化学物质（EDC）的主要来源。因此，有效去除废水中的 EDC 对水质至关重要。然而，传统的废水处理方法在去除这些污染物方面存在不足。因此，探索去除废水中 EDC 的新的、更有效的方法势在必行。酶处理方法已被认为是一种合适的选择。然而，木质素降解酶似乎是最有前途的一类用于去除 EDC 的酶，这可能是因为它们独特的催化特性和高氧化还原电位，可氧化广泛的有机化合物。因此，本文讨论了一些木质素降解酶（漆酶、锰过氧化物酶和多功能过氧化物酶）在去除废水中 EDC 方面的潜力，并提出了一种去除废水中 EDC 的新型废水处理工艺方案。
