摘要
采用高级氧化+生化组合工艺处理炼油污水处理过程中的反渗透浓水。抽取1个月的运行数据进行分析,结果表明:反硝化滤池对总氮的去除率平均为68.42%,生物滤池+臭氧接触池对COD的去除率平均为51.75%,对总磷的去除率平均为51.41%,该工艺有较强的抗冲击能力,出水能达到排放标准。
The advanced oxidation + biochemical combination process is used to treat the reverse osmosis concentrated water in the refinery wastewater treatment process. The results from one month's operation data showed that the removal rate of total nitrogen by denitrification filter was 68.42% on average, and the removal rate of COD by biofilter + ozone contact pool was 51.75% on average. The average removal rate of TP is 51.41%. The process has strong impact resistance, and the effluent can meet the discharge standard.
