臭氧-活性炭技术对膜生物反应器膜污染减缓研究
Research on the influences of ozonation-activated carbon technology on membrane fouling mitigation in membrane bioreactor
摘要
Abstract
This study was aiming at investigating the effects of ozonation-activated carbon technology on membrane fouling mitigation in membrane bioreactor (MBR). The results from the short-term experiment showed that power activated carbon (PAC) would improve the efficiency of ozone. When the ozone dosage was more than 0.25 mg/(gSS), the filterability of mixed liquor would deteriorate. Analysis of residual ozone in the effluent indicated that PAC would benefit to maintain the constant ozone concentration in the bulk solution. The introduction of ozonation-activated carbon technology into the MBR system would be beneficial to the system because membrane fouling could be controlled in long-term experiment. The microbial activity was somewhat inhibited, however, the effluent quality of the system was affected at a minimal level. Ozonation-activated carbon could reduce the protein and carbohydrate fractions in the soluble microbial products (SMP). The amount of loosely bound extracellular polymeric substances (LB) and the protein fractions in extracellular polymeric substances (EPS) were also decreased obviously by ozonation-activated carbon technology. These findings indicated the feasibility of using ozonation-activated carbon technology to control MBR membrane fouling.关键词
