Chromaticity of cigarette industry wastewater increase when treating by aerobic due to large quantities of lignin, nicotine and carbohydrate. Ozone and advance oxidation are proposed for degradation and decoloration of cigarette wastewater that processed by aerobic. The result shows that ozone process has its advantage of high decoloration rate, simple operation and low operation cost. Optimum parameters of ozone process are ozone dosage of 37.65mg/L, reaction time of 15min, reaction pH of 7.0-9.0. The COD removal rate is 38.3% when the decoloration rate is 57.5%. Operation cost of ozone process is 0.4 yuan/m3.
