UASB 和微生物固定化反应器降解含聚废水组合工艺
Degradation of HPAM-containing wastewater with integrated process of UASB and immobilized microorganism reactor
摘要
Abstract
Polymer flooding technique has become an important method of enhanced oil recovery. But the application of partially hydrolyzed polyacrylamide (HPAM) in oilfield meets many environmental problems. Based on water analysis and biodegradability analysis of HPAM-containing wastewater, improved biodegradability of wastewater was achieved. Laboratory simulation treatment of wastewater was performed by the “flotation-up-flow anaerobic sludge bed (UASB)-hydrolysis acidification-immobilized microorganism reactor” integrated process. There were two parts in simulation experiment,one was static,and the other was dynamic. After 2 d static biochemical treatment,the degradation ratio of HPAM in wastewater was up to 89.7%. And in dynamic simulation experiment, after 2 d treatment,the degradation ratio of HPAM was up to 88.65%,that of oil was 99.40%,that of COD was 93.40%. HPAM degradation products were analyzed by scanning electron microscopy (SEM) and infrared spectroscopy. The results showed that HPAM was transformed from bigger molecules into smaller molecules and acylamino group in HPAM was transformed into carboxyl group.关键词
