Detergents are emerging contaminants in water that require immediate attention due to their widespread use industrially and domestically. However, review articles on detergent treatment methods are not readily available in the literature as this topic is often overlooked. Various oxidation techniques have been applied to eliminate surfactants from the effluents completely. The photocatalytic treatment method is one of the most promising environmental-friendly oxidation technologies to degrade organic pollutants. Photocatalysis using TiO2 as a catalyst shows outstanding properties, including excellent thermal and chemical stability, nontoxicity, and high photocatalytic degradation ability towards most of the organic compounds present in the wastewater. This paper reviews the research on photocatalytic degradation of detergent contaminated wastewater and the parameters that affect the semiconductor’s photocatalytic activity. Lastly, critical remarks are also presented on the photodegradation treatment of laundry detergent wastewater, the economic feasibility of photodegradation treatment on an industrial scale, and suggestions for future work.

洗涤剂污染废水的光催化处理:当前进展简述

洗涤剂是水中的新兴污染物,由于其在工业和家庭中的广泛使用,需要立即引起注意。然而,关于洗涤剂处理方法的评论文章在文献中并不容易获得,因为这个话题经常被忽视。已经应用了各种氧化技术来完全消除流出物中的表面活性剂。光催化处理方法是最有前途的环保氧化技术之一,可降解有机污染物。使用 TiO 2的光催化作为催化剂,它具有出色的性能,包括出色的热稳定性和化学稳定性、无毒以及对废水中存在的大多数有机化合物的高光催化降解能力。本文综述了洗涤剂污染废水的光催化降解研究以及影响半导体光催化活性的参数。最后,还就洗衣液废水的光降解处理、工业规模光降解处理的经济可行性以及对未来工作的建议提出了批评意见。
