Abstract: It studies the degradation of reactive black dye by using engineering photocatalytic reactors coated with nanoscale TiC2 under different experiment conditions to gain the optimal parameters for the real pr~ect．Results indicate that the combined mode of UV／Nicke1．Net／TiC，has the highest degradation efficiencv for reactive black dye，and that the percent age of decolorization may achieve 94．76 ％ in 240 min．With the increase of the initial concentration of the dye，the percent age of decolorization will decline obviously．When the initia1 concentration is 20 mg／L，decolorization percent is more than 98．35％ after 240 min reaction period． Better degradation effect could be got under the condition of pH value equal to 5．reaching 94．2％ ．The degradation process can also be controlled by adding H2 O2，and when the content of H2 02 is l g／L，decolorization percentage can reach up to 98． 6 ％ after 1 50
mins’treatment．
