摘　　要：采用高效厌氧氨化池+组合脱氮池+气浮池组合工艺处理氨纶废水,处理规模为500 m^3/d,对COD和NH_3-N的平均去除率分别为97.9%和92.4%,出水水质达到设计出水要求,满足《污水综合排放标准》(GB 8978—1996)一级标准;采用砂滤+炭滤+袋式过滤器+反渗透+折点加氯处理中水并回用,每吨中水可节省0.6元。因此,该氨纶废水处理工艺具有较好的环境效益和经济效益。The combined process of high efficient anaerobic ammoniation, complex nitrogen re- moval, air flotation was used to treat spandex wastewater. The treatment capacity was 500 m3/d. The av- erage removal rate of COD and NH3 - N was 97.9% and 92.4% respectively. The effluent quality met the first grade of Integrated Wastewater Discharge Standard（ GB 8978 - 1996） as designed. Then the ef- fluent was further reclaimed by combined process of sand filter ＋ carbon filter ＋ bag filter ＋ reverse osmo- sis ＋ breakpoint chlorination, and the economic benefit of 0.6 CNY/m3 for reuse water could be genera- ted. Therefore, this process showed good environmental and economic benefits for treating spandex wastewater.
