The occurrence and removal mechanisms of bisphenol A (BPA) and its analogues in municipal WWTPs were critically reviewed in this article. BPA appeared to be the dominant bisphenol, and the removal efficiency of bisphenols was in the order of bisphenol AP>bisphenol P>bisphenol F>bisphenol Z>bisphenol C>bisphenol S>bisphenol B>BPA>bisphenol E>bisphenol AF. It was also found that BPA removal showed linear relationships to those of its analogues, which have been proven by BPA vs BPS or BPF. BPA removal performances in different treatment processes ranked from low to high are primary treatment, lagoon process, biological aerated filter, and activated sludge. Lab-scale studies showed that >50% BPA can be removed by sewage sludge estimated with the BPA solid water distribution coefficients, which showed that sludge adsorption played an important role on BPA removal. The theoretically predicted removal of BPA in municipal WWTP showed that it is readily biodegradable, which deviate from its on-site investigations. Existence of BPA conjugates in raw municipal wastewater as well as newly produced BPA degraded or migrated from microplastic materials are possible two main reasons.
本文对市政污水处理厂中双酚 A（BPA）及其类似物的产生和去除机制进行了批判性的回顾。BPA 似乎是占主导地位的双酚，双酚类物质的去除效率顺序为双酚 AP>双酚 P>双酚 F>双酚 Z>双酚 C>双酚 S>双酚 B>BPA>双酚 E>双酚 AF。研究还发现，BPA 的去除与已被证实的 BPA 与 BPS 或 BPF 之间存在线性关系。不同处理工艺中 BPA 的去除性能从低到高依次为一级处理、塘处理、生物曝气滤池和活性污泥。实验室规模的研究表明，用 BPA 固-水分配系数估算，超过 50%的 BPA 可以被污水污泥去除，这表明污泥吸附对 BPA 的去除起着重要作用。市政污水处理厂中 BPA 的理论预测去除表明其易生物降解，这与现场调查结果不符。原城市废水中 BPA 结合物的存在以及新产生的 BPA 从微塑料材料中降解或迁移，可能是两个主要原因。
