摘　　要：在对纺织染整企业集聚、环境位置敏感的两个典型区域调研的基础上,通过类似重金属标准和毒性类比、排污治理情况及水体底泥中锑含量的分析、水环境承载力和允许排放浓度计算等技术论证,提出环境敏感地区纺织染整工业锑的排放限值按不同排放情形可分别设定为0.1 mg/L和0.05 mg/L。工程实例表明,采用基于聚合硫酸铁混凝沉淀法的高低浓度废水分质处理技术可满足排放限值要求,且经济成本可接受。Based on the investigation of two typical regions that textile dyeing and finishing enterprises gathered and environmentally sensitive,heavy metal standards and toxicity analogy,sewage treatment situation,analysis of antimony content in sediment,calculation of water environment carrying capacity and allowable emission concentration,etc,the emission limits of antimony in textile dyeing and finishing industry in environmentally sensitive area were set as 0.1 mg/L and 0.05 mg/L,respectively,according to different emission situations.The engineering case showed that separated technologies of treatment for high or low concentration of wastewater could meet the requirements of emission limits by using PFS(polymerized ferric sulfate)coagulative precipitation,and the economic cost was acceptable.
