臭氧催化高级氧化技术在污水处理厂尾水处理中的应用研究

Treatment of Advanced Denitrification Effluent by Ozone Catalytic Advanced Oxidation Technology

依据臭氧催化高级氧化的机理,通过中试试验,探究不同臭氧投加量对出水水质指标的影响,并依据实际运行情况,测算出运行成本。在臭氧投加量为15~30 mg/L的情况下,臭氧对COD表现出较好的去除效果,平均去除率可达大约55%,同时有较好的杀菌、消毒效果,生产电单耗为7.88元/m^(3)。

Based on the mechanism of ozone-catalyzed advanced oxidation,this paper explores the influence of different ozone dosages on the effluent quality indicators through pilot tests,and calculates the operating cost based on actual operating conditions.The results show that when the dosage of ozone is 15~30 mg/L,the removal effect of ozone oxidation on COD is better,and the average removal rate can reach about 55%.Meanwhile it has good sterilization and disinfection effects on the fecal coliforms,and the consumption of produced electricity bills is 7.88 yuan/m^(3).
