【摘要】 水中的卤化物具有致癌和致突变性,一般不存在于天然水体,是人为污染的标志。美国环保局提出的129种优先污染物中,有机卤化物约占60%,以 AOX(Absorbable Organic Halogens)表征的有机卤化物已成为一项国际性水质指标。纺织品的染整加工是环境污染的一个重要污染源,且具有水量大、水质复杂的特点。常见的羊毛脱脂剂、杀虫剂、干洗剂、漂白剂等均属有机卤化物。然而在我国的印染废水排放标准中,化学需氧量(COD)为主要考核指标,AOX 的问题并未被引起重视。本文系统地介绍了 AOX 的定义及其由来,详细地列举了纺织染整加工过程中的 AOX 源,文章最后还简要介绍了 AOX 的治理。更多还原

【Abstract】 The aquatic halogenide is an artificial polluting mark and generally nonexistent in natural water, which is provided with carcinogenesis and mutagenicity.The organic halogenide accounts for 60% of 129 kinds of initiative pollutant in the American Environmental Protection Bureau’s list. The organic halogenide of AOX(the Halogens of the Absorbable Organic) has become an international water quality index.The dyeing and finishing process of textile is an important pollutant source to the environment,which has the characteristic of consuming great deal of water and complicated factors in water quality.The familiar wool degreases,insecticide, dry cleaning,bleach..etc, all belong to organic halogenide.In China, Chemical Oxygen Demand (COD) is the mainly investigate index in the exhaustion standard of water pollutants for dyeing and finishing process of textile industry, nevertheless,the problem of AOX has not been pay attention to.This text introduced AOX definition and origin systematically, and enumerated the AOX source in the dyeing and finishing process.This article also briefly introduced the treatment of AOX.更多还原
