Abstract

In this study, effects of variation of flow and accumulation of suspended solids (SS) on the performance of anaerobic/aerobic biofilm system were investigated through the laboratory test using synthetic wastewater and the field test using grey water. Effects of flow variation scarcely appeared on the time change of effluent quality in both cases where daily average hydraulic retention time (HRT) in anaerobic filter was 20h and that of aerobic filter was 6.7h. In the field test, however, removal rate of organic substances was lower (20-30%) than that of the laboratory test (90%), since SS content in grey water accumulated in the anaerobic filter which led dissolution of organic substances from accumulated SS, blocking, and short-circuit flow. Moreover, it was confirmed by the batch test that constituent of grey water has lower resolution for microorganisms and is more difficult to nitrate than synthetic waste water. 24 refs., 11 figs., 4 tabs.
