| 中文摘要: |
| 介绍了采用厌氧酸化-序批式活性污泥法处理甲醛废水。在反应期缺氧段，
采用中高温生物催化酸化，对季戊四醇、甲醛废水进行初级降解；在反应好氧段，进一步降解上一阶段的水解产物。运行结果表明，BOD5负荷0.04～0.08kgBOD5/
kgMLSS.d，甲醛负荷0.011～0.022kg/kgMLSS.d.当反应期缺氧段为20h，好氧段为
11h，甲醛去除率可以达到98％，CODcr去除率90％以上。 |
| 英文摘要: |
| Anaerobic acidification -SBR process (the combination of anaerobic phase with aerobic phase) was used to treat formaldehyde wastewater.In anaerobic phase, C 5H 8(OH) 4 and formaldehyde wastewater were degraded primarily by middle-high temperature biological acidification, and then the hydrolytic products of the above phase were degraded further in anaerobic phase. The results show that when anaerobic time is 16 hours, aerobic time 11 hours and while BOD5 load rang is from 0 04 to 0.08 kgBOD5/kgmlss.d, formaldehyde load rang from 0.01 to 0 02 kg/kgmlss.d, 98% removal of formaldehyde and more than 90% removal of CODcr are obtained . |
