摘要
研究了厌氧折流板反应器(ABR)分别与跌水曝气和曝气生物滤池组合工艺对农村生活污水中COD_(Cr)和氨氮的去除效果,并对两种组合工艺去除效果进行了比较。结果表明:采用ABR—好氧组合工艺处理生活污水,COD_(Cr)的平均去除率基本上稳定在84.2%左右,这说明生活污水经过ABR厌氧反应器和好氧处理后,能有效去除污水中的有机物;在后续好氧段,采用跌水曝气作为后处理,COD_(Cr)去除率比单独采用ABR提高了9.5%,采用曝气生物滤池作为后处理,COD_(Cr)去除率提高了24.9%,与ABR—跌水曝气相比,采用ABR—曝气生物滤池去除COD_(Cr)的效果较好;ABR—好氧组合工艺对氨氮的去除效果较差,达不到理想的去除效果。
It studied that removal efficiencies of COD_(Cr) and ammonia nitrogen of domestic sewage from countryside using ABR combined with waterfall aeration or aeration biological filtration.I compared the removal efficiencies of the two combined processes,and give the conclusion that:the removal rate of COD_(Cr) basically is around 84.2%at an average using ABR combined with aerobic process in treatment of domestic sewage.It illustrates that we can remove the organic matter in water effectively using ABR combined with aerobic process.In the follow-up aerobic stage,the removal rate of COD_(Cr) is increased by 9.5%using waterfall aeration than using the ABR alone.The removal rate of COD_(Cr) is increased by 24.9%using aeration biological filtration than using the ABR alone.It is better using aeration biological filtration compared with using hydralic drop aeration in COD_(Cr) removal effect.The removal effect of ammonia nitrogen can not achieve the desired result using ABR combined with aerobic process.
