Abstract
Experiments were conducted to examine the effects of nylon 66 chemical wastewater treatment by active carbon film filler contact oxidation process. The results showed that the formation of biofilm was relatively rapid on the surface of active carbon film filler, and the treatment efficiency was stable. The removal rate could reach 88.9% and 46.00% for COD and NH3-Nrespectively when the HRT was 22 hours, and the influent concentration of COD was 1036.6mg/L, NH3-N88.7mg/L. As the influent concentration of COD andNH3-N increased to 1915.4mg/L and 123.6mg/Lrespectively, the removal rate of COD could be up to89.7% while NH3-N reduced to 21.4%. Meanwhile moderate swing of filler was beneficial for high treatment efficiency and preventing sludge accumulation.
