A critical review on advances in the practices and perspectives for the treatment of dye industry wastewater

Rapid industrialization has provided comforts to mankind but has also impacted the environment harmfully. There has been severe increase in the pollution due to several industries, in particular due to dye industry, which generate huge quantities of wastewater containing hazardous chemicals. Although tremendous developments have taken place for the treatment and management of such wastewater through chemical or biological processes, there is an emerging shift in the approach, with focus shifting on resource recovery from such wastewater and also their management in sustainable manner. This review article aims to present and discuss the most advanced and state-of-art technical and scientific developments about the treatment of dye industry wastewater, which include advanced oxidation process, membrane filtration technique, microbial technologies, bio-electrochemical degradation, photocatalytic degradation, etc. Among these technologies, microbial degradation seems highly promising for resource recovery and sustainability and has been discussed in detail as a promising approach. This paper also covers the challenges and future perspectives in this field.

快速工业化在为人类带来生活福祉的同时，也对生态环境造成了显著负面影响。诸多工业活动引发的污染问题急剧加剧，其中印染工业产生的含有危险化学物质的大量废水尤为突出。尽管当前已通过化学法与生物法实现了此类废水处理与管控的诸多突破性进展，但行业研究思路正出现新兴转向：重心逐渐转向从废水中回收资源，并以可持续方式开展废水治理。本综述旨在阐述并探讨印染工业废水处理领域当前最前沿的技术与科研进展，涵盖高级氧化法（Advanced Oxidation Process）、膜过滤技术、微生物技术、生物电化学降解、光催化降解等多种技术路径。在各类技术中，微生物降解在资源回收与可持续发展方面展现出极高的应用潜力，本文亦将其作为极具前景的技术路径展开详细论述。本文同时涵盖了该领域当前面临的挑战与未来发展展望。
