Ozone oxidation treatment of second-grade effluent of cephalosporins wastewater was investigated. By means of orthogonal experiments and single factor experiments, the optimal operating conditions for the advanced treatment by ozone oxidation were as follows: 30 min of reaction time, 21.54 mg/L of ozone flux and 10.0 of initial pH value. Under this condition, the highest COD removal were 54.83% and COD could be dropped to 112.93 mg/L, meeting for the“Chemical synthetic pharmaceutical industry water pollution discharge standard”(GB21903—2008). The reaction was conformed to the first order kinetics reaction equation.
