Abstract: (1367 Views)
Background: Perchloroethylene (PCE) is a chlorinated aliphatic hydrocarbon which has been widely used in some industries. Industrial wastewaters polluted with PCE must be treated because of its possible carcinogenic effects. Since an Anaerobic Migrating Blanket Reactor (AMBR) has never been used in PCE biodegradation, this study aimed to determine its ability to biodegrade PCE with higher concentrations than those previously studied. Methods: A laboratory scale AMBR, with a total volume of 10 liters and four compartments for biodegradation of PCE in synthetic substrate, was used. The reactor was seeded with anaerobic digested sewage sludge. Then, the performance of the reactor was evaluated during 4 phases through which PCE loading rate increased from 3.75 to 75 mg/L.d. Hydraulic retention time (HRT) was fixed at 32 hours. Findings: Optimum 98% COD removal efficiency through organic loading of COD was obtained as 3.1g/L.d. Optimum 99.8% PCE removal efficiency was observed at a loading rate equal to 37.5 mg/L.d. Average COD and PCE removal efficiency for the whole active period of the reactor were 91.4 and 99.5%, respectively. Conclusion: According to our results, a full-scale AMBR can be used as a simple, efficient, and reliable method for treatment of PCE in real polluted industrial wastewater.
