| 摘 要： | 采用臭氧-曝气生物滤池工艺对广东某港口化学品废水进行处理。针对此类废水COD高、水质变化大、成分复杂的特点,探讨了废水的初始pH、臭氧投加量和催化剂等因素对臭氧氧化的影响,臭氧对废水可生化性的改善情况、不同曝气生物滤池停留时间对废水COD去除率的影响。试验结果表明:进水化学需氧量(COD)约1700mg/L,在臭氧投加量538～716mg/L,BAF水力停留时间30h的情况下,经组合工艺处理后出水COD低于250mg/L,处理后废水达到排放城市污水处理厂的废水接纳标准。

| Abstract: | Ozonizing-biological aerated filter(BAF)process was used to treat port chemicals cabin washing wastewater.Based on properties of port chemicals cabin washing wastewater with high COD,variable quality and complicated composition,initial pH,dosage of ozone and catalyzer on COD removal efficiency,biodegradation ability of wastewater and effect of hydraulic retention time(HRT)of BAF were investigated.Results showed that under the conditions of influent COD about 1,700mg/L,dosage of ozone 538～716mg/L and HRT of BAF 30h,effluent COD was less than 250mg/L,with the treated wastewater satisfactory to the receiving standard of urban wastewater treatment plant. |
