摘　　要：为了改善印染废水的色泽,降低印染废水对环境的污染,文章采用双氧水加助剂的方法研究了印染废水的脱色工艺。采用L9(34)正交试验,确定硅酸钠、尿素、柠檬酸钠了三种漂白助剂的最佳用量:硅酸钠用量为0.1%,尿素用量为0.4%,柠檬酸钠用量为0.1%,在此脱色工艺下的产品的脱色率达到98.83%。In order to get finer color, The H202 was utilized to decolor the printed wastewater by adding composite additives. The L9（34） orthogonal experiment were used in the study, with Na2SiO3, H2NCONH2, C6H5Na307. Then the data gotten were analyzed to choose the best treatment. Results show that the best dosage formulation are 0. 1% of Na2SiO3, 0.4 % of H2NCONH2, 0.1% of C6HsNa3OT. The printed wastewater decoloration ratio is 98.83 %.
