Abstract:

An example of A²/Oprocess for treating surfactant wastewater is summarized. It is proved feasible, the key technolog y consists of a foam segregator and a UASB reactor. The COD value is degraded from above 1 200 mg/ L to below 150 mg/ L, the removal rate of COD is more than 85%. The waste water load is 80 m³/ d.

Key words: surfactant, anaerobic hydrolysis-acidification oxidization(A²/O), upf low anaerobic sludge blanket(UASB) reactor, foam separat ion, contact oxidation

摘要：

总结了A2 /O法处理表面活性剂废水的一个实例。实践证明,A2 /O法处理表面活性剂废水是可行的。其关键技术在于泡沫分离器和UASB反应器。废水经A2 /O工艺处理后,COD值从 12 0 0mg/L以上降至 15 0mg/L以下,COD去除率达 85 %以上,废水处理量为 80m³ /h。
