摘要
采用臭氧氧化法对头孢合成废水二级出水进行深度处理,通过正交和单因素实验得出最佳反应条件为:反应时间为30 min、臭氧通量为21.54 mg/min和初始反应pH值为10.0,在此条件下COD去除率达到54.83%,COD可降到112.93 mg/L,满足《化学合成类制药行业水污染排放标准》(GB21903—2008)。反应符合一级动力学反应方程。
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.
