Carwash wastewater (CWW) is considered as an important source of either water pollution or water consumption. Therefore, its treatment is critical not only from the prevention of environmental contamination but also from the recycling of such high-volume water source. Unfortunately, the effective treatment of CWW is almost unknown, complex, and expensive. To overcome the former challenge, this study aimed to systematically review different technologies for CWW treatment. For this, a comprehensive literature survey was conducted and 48 research articles were found suitable to be included in the investigation. The included studies were of coagulation and adsorption (n = 5), membrane-based technologies (n = 15), and electrochemical (n = 11) and combined (n = 17) systems. This comprehensive review showed that the treatment methods of advanced filtration membrane techniques, electrical and chemical coagulation, and advanced oxidation processes can be effective in the removal of pollutants from carwash wastewater (CWW). The mining of different studies, however, showed that the combined methods are the most promising option in the remediation of such wastewater.
洗车废水（CWW）被认为是水污染或水耗的重要来源。因此，不仅要从防止环境污染的角度，还要从回收这种高用水量水源的角度来对其进行处理。不幸的是，CWW 的有效处理几乎是未知的、复杂的和昂贵的。为了克服上述挑战，本研究旨在系统地回顾 CWW 处理的不同技术。为此，进行了全面的文献调查，发现了 48 篇适合纳入调查的研究文章。所包括的研究包括混凝和吸附（n = 5）、基于膜的技术（n = 15）、电化学（n = 11）和联合（n = 17）系统。本综述表明，先进过滤膜技术、电和化学混凝以及高级氧化工艺等处理方法可以有效去除洗车废水中的污染物。然而，对不同研究的挖掘表明，联合方法是修复此类废水的最有前途的选择。
