Textile industry wastewater (TIWW) is considered as one of the worst polluters of our precious water and soil ecologies. It causes carcinogenic, mutagenic, genotoxic, cytotoxic and allergenic threats to living organisms. TIWW contains a variety of persistent coloring pollutants (dyes), formaldehyde, phthalates, phenols, surfactants, perfluorooctanoic acid (PFOA), pentachlorophenol and different heavy metals like lead (Pb), cadmium (Cd), arsenic (As), chromium (Cr), zinc (Zn) and nickel (Ni) etc. TIWW is characterized by high dye content, high pH, chemical oxygen demand (COD), biochemical oxygen demand (BOD), total dissolved solids (TDS), total suspended solids (TSS), total organic carbon (TOC), chlorides and sulphates. Thus, requires adequate treatment before its final discharge into the water bodies to protect public health and environment. The treatment of TIWW is a major challenge as there is no particular economically feasible treatment method capable to adequately treat TIWW. Therefore, there is a need to develop a novel, cost-effective and eco-friendly technology for the effective treatment of TIWW. This review paper emphasizes on the different textile industry processes, wastewater generation, its nature and chemical composition, environmental impacts and health hazards and treatment approaches available for TIWW treatment. It also presents various analytical techniques used to detect and characterize TIWW pollutants and their metabolites, challenges, key issues and future prospectives.

纺织工业废水中持久性着色污染物的生态毒理和健康问题及环境安全处理方法

纺织工业废水(TIWW)被认为是我们宝贵的水和土壤生态系统中最严重的污染源之一。它对活生物体造成致癌,诱变,遗传毒性,细胞毒性和变应原性威胁。TIWW包含多种持久性着色污染物(染料),甲醛,邻苯二甲酸盐,酚,表面活性剂,全氟辛酸(PFOA),五氯苯酚和不同重金属,如铅(Pb),镉(Cd),砷(As),铬(Cr ),锌(Zn)和镍(Ni)等。TIWW的特点是染料含量高,pH高,化学需氧量(COD),生化需氧量(BOD),总溶解固体(TDS),总悬浮固体(TSS) ),总有机碳(TOC),氯化物和硫酸盐。因此,在将其最终排入水体之前需要进行适当的处​​理,以保护公共健康和环境。TIWW的治疗是一项重大挑战,因为没有一种能够充分治疗TIWW的经济上可行的治疗方法。因此,需要开发一种新颖的,具有成本效益的和生态友好的技术来有效治疗TIWW。这篇综述文章重点介绍了不同的纺织工业流程,废水的产生,废水的性质和化学成分,环境影响和健康危害以及可用于TIWW处理的处理方法。它还介绍了用于检测和表征TIWW污染物及其代谢物,挑战,关键问题和未来前景的各种分析技术。具有成本效益的环保技术,可有效治疗TIWW。这篇综述文章强调了不同的纺织工业过程,废水的产生,废水的性质和化学成分,环境影响和健康危害以及可用于TIWW处理的处理方法。它还提供了用于检测和表征TIWW污染物及其代谢物,挑战,关键问题和未来前景的各种分析技术。具有成本效益的环保技术,可有效治疗TIWW。这篇综述文章重点介绍了不同的纺织工业流程,废水的产生,废水的性质和化学成分,环境影响和健康危害以及可用于TIWW处理的处理方法。它还介绍了用于检测和表征TIWW污染物及其代谢物,挑战,关键问题和未来前景的各种分析技术。
