摘　　要：本文对纺织染整企业废水的AOX进行了实地取样检测,结果表明纺织染整生产废水中AOX浓度较低,7家企业中有5家处理后出水可满足新的国家标准要求。2家企业超标主要是因为污水处理过程中过量投加含氯脱色剂导致出水AOX浓度升高。纺织染整行业中AOX有三方面来源:纤维种植过程中使用的农药;纺织品加工过程中使用的染料和助剂;废水处理过程中投加的含氯脱色剂。避免使用含有卤素的染料、助剂以及水处理化学药剂,寻求其替代产品是避免AOX污染的最佳方法。This paper was based on the work of sampling and monitoring wastewater from textile enterprises.The results showed that the concentration of AOX in the effl uent was low,and wastewater from five of the seven selected enterprises could meet the requirement of national standard.The main reason why two else enterprises failed was the excessive use of chlorine decolorants.The AOX pollutant came from pesticide used in fiber plant process,dyes and auxiliaries used in dyeing and finishing process and chlorine decolorizing agent used in wastewater treatment.The optimal method to avoid AOX pollution was using dyes,additives and decolorants without halogen and seeking for substitutions.
