In the last years, a lot of emerging contaminants, such as, endocrine disruptors compounds (EDCs), pharmaceuticals, and personal care products (PPCPs) have been detected in wastewater. Because of their toxicity and possible adverse effects on the environment and humans, their release from urban wastewater treatment plants (UWWTPs) effluents should be minimized, particularly when a wastewater reuse for crops irrigation is expected. Many processes have been investigated for advanced treatment of UWWTP effluents as well as for emerging contaminant degradation; among these, adsorption process was successfully used to remove EDCs and PPCPs from wastewater. This article shortly reviews EDCs and PPCPs removal from UWWTP effluents by adsorption process using conventional and non-conventional adsorbents. The fate of EDCs and PPCPs in UWWTPs and the implications for agricultural wastewater reuse has been addressed too. In spite of the adsorption process looking to be a valuable alternative to other advanced technologies for the removal of emerging contaminants from wastewater, some gaps still remain to evaluate the actual feasibility at full scale. However, according to a few studies available in scientific literature on the use of both powdered activated carbon and granular activated carbon at full scale, adsorption process by activated carbon is a promising, potentially effective, and economically feasible solution for producing safe wastewater for agricultural reuse.
在过去的几年中,许多新兴污染物,如内分泌干扰化合物(EDCs)、药品和个人护理产品(PPCPs),已在废水中被检测到。由于它们的毒性以及对环境和人类可能产生的负面影响,应尽量减少它们从城市废水处理厂(UWWTP)废水中的释放,特别是当预期将废水再用于灌溉作物时。许多工艺已被用于 UWWTP 废水的深度处理和新兴污染物的降解;其中,吸附工艺已成功用于从废水中去除 EDCs 和 PPCPs。本文简要回顾了使用常规和非常规吸附剂通过吸附工艺从 UWWTP 废水中去除 EDCs 和 PPCPs 的情况。还讨论了 EDCs 和 PPCPs 在 UWWTP 中的归宿以及对农业废水再利用的影响。尽管吸附工艺似乎是一种有价值的替代其他先进技术的方法,可用于从废水中去除新兴污染物,但仍存在一些差距需要在全面评估实际可行性。然而,根据科学文献中关于在全规模使用粉末活性炭和颗粒活性炭的少数研究,活性炭吸附工艺是一种有前途、潜在有效的、经济可行的解决方案,可生产用于农业再利用的安全废水。
