摘要

通过实验考察了活性炭膜填料接触氧化法处理尼龙66化工废水的效果。结果表明，活性炭膜填料表面生物膜形成速度较快，处理效果稳定。当HRT为22 h时，COD和nh3 - n去除率分别达到88.9%和46.00%，进水COD浓度为1036.6mg/L, NH3-N88.7mg/L。当进水COD和NH3-N浓度分别增加到1915.4mg/L和123.6mg/L时，COD去除率可达89.7%，NH3-N去除率可降至21.4%。同时，填料的适度摆动有利于提高处理效率，防止污泥堆积。

Study on Treatment of Nylon 66 Chemical Wastewater by Active Carbon Film Filler Contact Oxidation Process

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.
