摘　　要：初步研究了用聚二甲基二烯丙基氯化铵（PDMDAAC）改性凹凸棒石和Fenton试剂联合对印染废水脱色和去除CODer的影响因素．结果表明：在改性凹凸棒石投加量为1．5g／L、25℃、pH=8～10、吸附时间15min条件下，印染废水色度去除率可达99．4％，CODer去除率可达85．4％，出水水质符合国家I级排放标准．The effects of decolorization and CODer degradation in treating dyeing wastewater are studied by a combined process of Fenton reagent plus modified attapulgite with polydimethy Idiallyl ammonium ehloride（PDMDAAC）. The results showed that the decolorization rate can meet 99.4% and CODer degradation rate can meet 85.4% under the best conditions of 1.5g/L of the PDMDAAC-attapulgite ,temperature 25℃ ,pH value 8 to 10 and 15 rain of adsorption time. The discharge is up to the first grade standard of china.
