Bisphenol A (BPA), an endocrine disrupting compound largely used in plastic and paper industry, ends up in aquatic systems via wastewater treatment plants (WWTPs) among other sources. The identification and quantification of BPA in wastewater (WW) and wastewater sludge (WWS) is of major interest to assess the endocrine activity of treated effluent discharged into the environment. Many treatment technologies, including various pre-treatment methods, such as hydrolysis, Fenton oxidation, peroxidation, ultrasonication and ozonation have been developed in order to degrade BPA in WW and WWS and for the production of WWS based value-added products (VAPs). WWS based VAPs, such as biopesticides, bioherbicides, biofertilizers, bioplastics and enzymes are low cost biological alternatives that can compete with chemicals or other cost intensive biological products in the current markets. However, this field application is disputable due to the presence of these organic compounds which has been discussed with a perspective of simultaneous degradation. The pre-treatment produces an impact on rheology as well as value-addition which has been reviewed in this paper. Various analytical techniques available for the detection of BPA in WW and WWS are also discussed. Presence of heavy metals and possible thermodynamical behavior of the compound in WW and WWS can have major impact on BPA removal, which is also included in the review.
双酚 A（BPA）是一种内分泌干扰化合物，广泛用于塑料和造纸行业，通过废水处理厂（WWTP）等途径进入水生系统。BPA 在废水（WW）和废水污泥（WWS）中的鉴定和定量对于评估处理后排放到环境中的废水的内分泌活性非常重要。为了降解 WW 和 WWS 中的 BPA，并生产基于 WWS 的增值产品（VAPs），已经开发了许多处理技术，包括各种预处理方法，如水解、芬顿氧化、过氧化物、超声和臭氧氧化。基于 WWS 的 VAPs，如生物农药、生物除草剂、生物肥料、生物塑料和酶，是低成本的生物替代品，可以在当前市场上与化学品或其他高成本的生物产品竞争。然而，由于这些有机化合物的存在，该领域的应用存在争议，本文从同时降解的角度对此进行了讨论。预处理会对流变学和附加值产生影响，本文对此进行了综述。还讨论了用于检测 WW 和 WWS 中 BPA 的各种分析技术。重金属的存在以及该化合物在 WW 和 WWS 中的可能热力学行为可能会对 BPA 的去除产生重大影响，这也包括在综述中。
