摘要
采用O_(3)/H_(2)O_(2)氧化预处理抗生素制药废水,系统考察pH、温度、固体催化剂对污染物去除效果的影响,并研究氧化预处理对厌氧生化工艺的影响,通过气相色谱-质谱分析氧化前后有机物的变化.结果表明,提高温度和降低pH对O_(3)/H_(2)O_(2)氧化有利,添加MnO2增强了催化氧化效果,而添加活性炭反而不利.氧化预处理降低了难生物降解有机物的浓度,使得厌氧生化工艺对COD去除效果由70.4%提高到81.9%.
Wastewater from antibiotic production is pre-treated by O_(3)/H_(2)O_(2) oxidation process.The influence of pH,temperature and solid catalyst on removal effect to COD pollutants is examined carefully and systemically.Meanwhile,the impact of O_(3)/H_(2)O_(2) oxidation pretreatment on anaerobic biochemical process is also studied,and GC/MS is utilized to characterize organic pollutants before and after the pretreatment.Results show that both higher temperature and lower pH are beneficial to the oxidation by O_(3)/H_(2)O_(2).For the catalyst,the addition of MnO_(2) can enhance the oxidation process while the addition of activated carbon weakens it. O_(3)/H_(2)O_(2) oxidation pretreatment drops the concentration of refractory pollutants,which helps anaerobic biochemical process to increase the removal efficiency of COD from 70.4% to 81.9%.
