摘要
采用A O生物接触氧化法处理化妆品废水的试验研究结果表明 :该工艺处理效果良好 ,在厌氧段和好氧段水力停留时间分别为 15h和 13h、有机负荷为 2 .85KgCOD m3·d时 ,不需任何预处理或后续深度处理 ,废水CODcr值可从 1780g L降至15 0mg L以下 ,去除率达到 93 .5 %以上。
The result of experiment study of cosmetics sewage treatment by biological contact oxidation indicates that the process is good. The bydraulic stay times are 15 h and 13 h separately for anaerobic and aerobic sections under organic load of 2.85 kg COD/m 3·d, and any pretreatment or conseguent deep treatment is unnessary, while CODcr value of sewage can be reduced from 1 780 mg/L to less than 150 mg/L with removal rate more than 93.5%.
