Abstract
The BAF loaded with new ceramic filter material was researched to treat wastewater in comparison with the BAF loaded with biogenic ceramisite agitator. The operational parameter was optimized such as hydraulic retention time, reflux ratio, backwash cycle, etc. The result showed that when the average influent CODcr was 135.6 mg/L, NH4+-N 42.1 mg/L and TP 0.69 mg/L, the removal efficiencies of The BAF loaded with new ceramic filter material were 81.2%, 99.8%, and 68.1% respectively at the condition of the HRT=1.5h. New ceramic filter material required less water to backwash and had better effect than biogenic ceramisite agitator at the same condition because its low density and strong mechanical robustness. The optimal backwash periodicity was two days and expansion coefficient was 20%-30%. The optimal reflux ratio was 150% when two BAFs were connected in series for nitrogen remove.
