Pharmaceutical active compound (PhAC) residues are considered an emerging micropollutant that enters the aquatic environment and causes harmful ecotoxicity. The significant sources of PhACs in the environment include the pharmaceutical industry, hospital streams, and agricultural wastes (animal husbandry). Recent investigations demonstrated that wastewater treatment plants (WWTPs) are an important source of PhACs discharging ecosystems. Several commonly reported that PhACs are detected in a range level from ng L to μg L concentration in WWTP effluents. These compounds can have acute and chronic adverse impacts on natural wildlife, including flora and fauna. The approaches for PhAC removals in WWTPs include bioremediation, adsorption (e.g., biochar, chitosan, and graphene), and advanced oxidation processes (AOPs). Overall, adsorption and AOPs can effectively remove PhACs from wastewater aided by oxidizing radicals. Heterogeneous photocatalysis has also proved to be a sustainable solution. Bioremediation approaches such as membrane bioreactors (MBRs), constructed wetlands (CWs), and microalgal-based systems were applied to minimize pharmaceutical pollution. Noteworthy, applying MBRs has illustrated high removal efficiencies of up to 99%, promising prospective future. However, WWTPs should be combined with advanced solutions, e.g., AOPs/photodegradation, microalgae-bacteria consortia, etc., to treat and minimize their accumulation. More effective and novel technologies (e.g., new generation bioremediation) for PhAC degradation must be investigated and specially designed for a low-cost and full-scale. Investigating green and eco-friendly PhACs with advantages, e.g., low persistence, no bioaccumulation, less or non-toxicity, and environmentally friendly, is also necessary.
药物活性化合物(PhAC)残留被认为是一种新兴的微量污染物,会进入水生环境并造成有害的生态毒性。PhAC 在环境中的重要来源包括制药工业、医院污水和农业废物(畜牧业)。最近的调查表明,废水处理厂(WWTP)是 PhAC 排放到生态系统中的一个重要来源。有几项研究报告表明,在 WWTP 废水中,PhAC 以 ng L 到 μg L 的浓度范围被检测到。这些化合物会对自然野生动物,包括植物和动物,产生急性和慢性的不利影响。在 WWTP 中去除 PhAC 的方法包括生物修复、吸附(如生物炭、壳聚糖和石墨烯)和高级氧化工艺(AOPs)。总的来说,吸附和 AOPs 可以有效地去除废水中的 PhAC,同时借助氧化自由基。多相光催化也被证明是一种可持续的解决方案。生物修复方法,如膜生物反应器(MBR)、人工湿地(CW)和基于微藻的系统,被应用于最大限度地减少药物污染。值得注意的是,应用 MBR 已经显示出高达 99%的高去除效率,具有广阔的未来前景。然而,WWTP 应该与高级解决方案相结合,例如 AOPs/光降解、微藻-细菌共生体等,以进行处理并最小化其积累。必须研究和专门设计更有效和新颖的 PhAC 降解技术(例如新一代生物修复),以实现低成本和全面应用。还需要研究具有优势的绿色环保型 PhAC,例如低持久性、无生物累积性、低毒性或无毒性,以及环境友好性。
