Pharmaceuticals and personal care products (PPCPs) are of emerging concerns because of their large usage, persistent nature which promised their continuous disposal into the environment, as these pollutants are stable enough to pass through wastewater treatment plants causing hazardous effects on all the organisms through bioaccumulation, biomagnification, and bioconcentration. The available technologies are not capable of eliminating all the PPCPs along with their degraded products but phycoremediation has the advantage over these technologies by biodegrading the pollutants without developing resistant genes. Even though phycoremediation has many advantages, industries have found difficulty in adapting this technology as a single-stage treatment process. To overcome these drawbacks recent research studies have focused on developing technology that integrated phycoremediation with the commonly employed treatment processes that are in operation for treating the PPCPs effectively. This review paper focuses on such research approaches that focused on integrating phycoremediation with other technologies such as activated sludge process (ASP), advanced oxidation process (AOP), Up-flow anaerobic sludge blanket reactor (UASBR), UV irradiation, and constructed wetland (CW) with the advantages and limitations of each integration processes. Furthermore, augmenting phycoremediation by co-metabolic mechanism with the addition of sodium chloride, sodium acetate, and glucose for the removal of PPCPs has been highlighted in this review paper.
药品和个人护理产品（PPCPs）是新兴的关注点，因为它们的使用量大，性质持久，承诺将其持续排放到环境中，因为这些污染物足够稳定，可以通过废水处理厂，对所有生物造成危险影响，通过生物积累、生物放大和生物浓缩。现有的技术无法消除所有 PPCPs 及其降解产物，但藻修复技术具有优于这些技术的优势，因为它可以在不产生抗性基因的情况下生物降解污染物。尽管藻修复技术有许多优点，但工业界发现难以将其作为单一阶段的处理工艺进行应用。为了克服这些缺点，最近的研究集中在开发将藻修复技术与通常使用的处理工艺相结合的技术上，以有效地处理 PPCPs。本文综述了将藻修复技术与其他技术（如活性污泥法（ASP）、高级氧化法（AOP）、上流式厌氧污泥床反应器（UASBR）、紫外线照射和人工湿地（CW））集成的研究方法，以及每种集成方法的优缺点。此外，本文还强调了通过共代谢机制增强藻修复技术的作用，通过添加氯化钠、乙酸钠和葡萄糖来去除 PPCPs。
