Dyes and other chemicals laden wastewater is a main environmental concern for increasing the textile industries in many parts of the world. Textile industries consume different kinds of manmade dyes or other chemicals and release huge extents of highly polluted water into the environment. This excessive dye laden wastewater has great impacts on photosynthetic activity in aquatic plants and animals, for example, fish. It may also affect human health due to the presence of components like heavy metals and chlorine in manmade dyes. Thus, wastewater effluent from textile industries must be treated before discharge into the water body. Treatment technologies observed in this review paper include biological treatment methods (fungi, algae, bacteria, and microbial fuel cells), chemical treatment methods (photocatalytic oxidation, ozone, and Fenton’s process), and physicochemical treatment methods (adsorption, ion exchange, coagulation, and filtration). This review also includes the hybrid treatment methods and their cost per m³ of treated wastewater analysis. There are alternative wastewater treatments systems at different steps of effluent generated from the textile operational unit recommend in this review work.

纺织工业废水处理技术

含有染料和其他化学品的废水是世界许多地区纺织业发展的主要环境问题。纺织工业消耗不同种类的人造染料或其他化学品，并向环境释放大量高度污染的水。这种含有过量染料的废水对水生植物和动物（例如鱼类）的光合作用活动有很大影响。由于人造染料中含有重金属和氯等成分，它还可能影响人类健康。因此，纺织工业的废水在排入水体之前必须经过处理。本综述论文中观察到的处理技术包括生物处理方法（真菌、藻类、细菌和微生物燃料电池）、化学处理方法（光催化氧化、臭氧、和芬顿工艺）和物理化学处理方法（吸附、离子交换、混凝和过滤）。该评论还包括混合处理方法及其每平方米的成本³处理后的废水分析。在本次审查工作中推荐的纺织运营单位产生的废水的不同步骤有替代的废水处理系统。
