摘　　要：针对活性染料染色废水排放量大、色度深、环境污染严重的问题,以C.I.活性红218模拟废水为研究对象,使用处理液吸光度值为评价指标,探究废水处理工艺参数对色度的影响规律。结果表明,助剂CR用于处理模拟废水时,适宜的温度、时间和浓度分别为80℃、30min和3%。相同条件下,助剂浓度和处理温度越高,废水色度降低越显著,所需处理时间越短。当处理时间超过15min后,酸性条件所对应的吸光度值最小,碱性次之,中性最大,pH=3时吸光度变化趋势与纯染液(pH=5)最为接近。废液中,NaCl浓度仅影响废水色度去除效率,但添加Na_(2)CO_(3)后会减弱废水色度去除效果。In order to solve the problems of large discharge,deep chromaticity and serious environmental pollution of reactive dye dyeing wastewater,C.I.Reactive Red 218 wastewater was used as the research object.The influence of wastewater treatment process on wastewater chromaticity was studied by measuring the absorbance.The results showed that when CR was used to treat the wastewater of CI.Reactive Red 218,the appropriate temperature,time and CR concentration were 80℃,30 min and 3%,respectively.The higher the CR concentration and temperature,the more significant the reduction of wastewater absorbance and the shorter the treatment time.When the treatment time exceeded 15 min,the absorbance corresponding to acidic conditions was the smallest,alkaline was the second,and neutral was the largest.The absorbance change trend of pH=3 was closest to that of dye solution(pH=5).NaCl concentration only affected the color removal fficiency of wastewater,but Na_(2)CO_(3)can slow down the color removal effect of wastewater.
