水污染是威胁人类文明可持续发展的严重环境问题之一。许多酚类化合物是危险的、有毒的、内分泌干扰的、致突变的、致畸的和/或致癌的。它们还对海洋生态系统造成严重破坏。因此，在污染废水排放到环境中之前将其从污染废水中去除是一项强制性任务。已经提出了几种处理苯酚污染的沃茨的方法。在所提出的处理方法中，有酶法。因此，本文的主要目的是介绍利用过氧化物酶和漆酶修复含酚废水的最新进展。均相和非均相酶法从废水中去除不同的酚类污染物将进行审查。最近关于关键业务因素影响的研究（即，温度和pH值）。此外，酶废水处理的新趋势将得到解决。指出了酶法处理含酚废水在大规模应用中面临的障碍和挑战。更重要的是，将提供一些解决该过程局限性并提高其效率和可行性的想法。这些想法可能会成为未来研究的基础，开发一种更有效的酶法处理酚类污染物污染的废水，这是一个日益严重的全球环境问题。
Water pollution is one of the serious environmental problems threatening the sustainable development of human civilization. Many phenolic compounds are hazardous, toxic, endocrine disrupting, mutagenic, teratogenic, and/or carcinogenic. They also cause severe damages to marine ecosystem. Accordingly, their removal from polluted wastewaters prior to its discharge to the environment is a mandatory task. Several processes have been proposed for treating phenol-contaminated waters. Among the proposed treatment processes is the enzymatic method. Thus, the key objective of this review article is to present the recent progress in utilizing peroxidases and laccases for the remediation of phenolic wastewaters. Both homogenous and heterogeneous enzymatic processes to remove different phenolic pollutants from wastewaters will be reviewed. Recent studies on the effects of the key operational factors (i.e., temperature and pH) will also be presented. Additionally, emerging trends in enzymatic wastewater treatment will be addressed. The obstacles and challenges facing the large scale applications of enzymatic remediation of phenolic wastewaters will be highlighted. More importantly, several ideas for addressing the limitations of the process and improving its efficiency and viability will be provided. These ideas might form the basis for future studies on developing a more effective enzymatic process for treating wastewaters contaminated with phenolic pollutants, which is a growing environmental problem worldwide.
