Waste water is a major environmental impediment for the growth of the textile industry besides the other minor issues like solid waste and resource waste management. Textile industry uses many kinds of synthetic dyes and discharge large amounts of highly colored wastewater as the uptake of these dyes by fabrics is very poor. This highly colored textile wastewater severely affects photosynthetic function in plant. It also has an impact on aquatic life due to low light penetration and oxygen consumption. It may also be lethal to certain forms of marine life due to the occurrence of component metals and chlorine present in the synthetic dyes. So, this textile wastewater must be treated before their discharge. In this article, different treatment methods to treat the textile wastewater have been presented along with cost per unit volume of treated water. Treatment methods discussed in this paper involve oxidation methods (cavitation, photocatalytic oxidation, ozone, H2O2, fentons process), physical methods (adsorption and filtration), biological methods (fungi, algae, bacteria, microbial fuel cell). This review article will also recommend the possible remedial measures to treat different types of effluent generated from each textile operation.
除了固体废弃物和资源浪费管理等其他小问题外,废水是纺织工业发展的主要环境障碍。纺织工业使用多种合成染料,由于织物对这些染料的吸收率很低,会排放大量高色度废水。这种高色度的纺织废水严重影响植物的光合功能。由于光穿透率低和耗氧量,它也会对水生生物产生影响。由于合成染料中存在的成分金属和氯,它对某些海洋生物形式也可能是致命的。因此,这种纺织废水在排放前必须进行处理。在本文中,介绍了处理纺织废水的不同处理方法以及单位处理水量的成本。本文讨论的处理方法包括氧化法(空化、光催化氧化、臭氧、过氧化氢、芬顿法)、物理法(吸附和过滤)、生物法(真菌、藻类、细菌、微生物燃料电池)。这篇综述文章还将推荐可能的补救措施,以处理各纺织工序产生的不同类型废水。
