摘要
采用A2/O-臭氧氧化-活性炭过滤的组合工艺对焦化废水进行处理,以解决其达标排放。进水COD 1267 mg/L,NH3-N 113 mg/L,SS150 mg/L左右时,工艺对COD、氨氮、SS的去除率分别达到93%、95%、95%,出水满足《污水综合排放标准》(GB8978-1996)一级标准。试验结果表明该工艺对焦化废水有很好的处理效果。
A^2/O-ozone oxidation-activated carbon filter treatment for coking wastewater was studied to solve substandard discharge. When influent COD was 1267 mg/L, influent NH3＋N was 113 mg/L, influent SS was 150 mg/L, the removal efficiency of the three were 93 %, 95 %, 95 % respectively. Effluent was up to the ＂Comprehensive sewage discharge standard＂（GB8978-1996）. Results showed that coking wastewater could be well treated using this process.
