摘　　要：研究了二氧化氯、活性炭组合法处理印染废水,确定了二氧化氯处理印染废水的最佳反应时间、pH、温度及氧化剂用量对脱色率的影响。二氧化氯使印染废水脱色率达到73%,后期用活性炭对印染废水进行吸附脱色。最终使印染废水脱色率达到92.44%,处理后的废水指标符合国家排放标准。Based on the possibility study of dying wastewater treatment, the combination of chorine dioxide and activated carbon used to select the relevant optimal influential factors for decoloration rate,such as reaction time,pH,temperature and dosage of oxidant. The decoloration rate of dying wastewater could reach about 73% by using chlorine dioxide. At last the decoloration rate of dying wastewater reach about 92.44% and indexes of treated wastewater met state standards for discharge of wastewater drainage when adsorbent discolouration of dying wastewater is carried out with active charcoal.
