玄武岩纤维填料应用于两种混合生长反应器的评价
|
摘要
采用单丝直径微米级的伞状玄武岩纤维(BF)作为填料,将其引入序批式反应器(SBR)和后置缺氧反硝化SBR外聚合物(EPS)含量和扫描电子显微镜形貌图,考察了两种SHBR的污水处理效果。试验结果表明:基于SBR的SHBR的出水COD、氨氮、总氮去除率分别为83.2%、89.9%、86.8%;基于后置缺氧反硝化SBR的SHBR优良,而基于后置缺氧反硝化SBR的SHBR的脱氮效果得到进一步的优化和提升。两种SHBR的BF填料中EPS含量分析结果显示:在好氧环境下,蛋白质(PN)的含量高于多糖(PS)的含量;在缺氧条件下,PS的含量明显高于PN的含量。
Umbrella-shaped basalt fiber(BF) with micron diameter as carrier was introduced into sequencing batch reactor(SBR) and post anoxic denitrification SBR to form two kinds of sequencing hybrid biological reactors(SHBRs). By analyzing the effluent quality of two kinds of SHBRs, the content of extracellular polymer substances(EPS) and the morphology, the affection of treating simulated municipal wastewater of two kinds of SHBRs was investigated. The results showed that the removal rates of COD, ammonia nitrogen and total nitrogen of SHBR based on SBR were 83.2%, 89.9% and 86.8%, respectively. The removal rates of COD, the ammonia nitrogen and total nitrogen of SHBR based on post anoxic denitrification were 87.6%,96.7% and 94.5%, respectively. The treatment effect of SHBR based on SBR was excellent, while the denitrification effect of SHBR based on post anoxic denitrification SBR was further optimized and improved.The results of EPS analysis of two kinds of SHBRs showed that the content of protein(PN) was higher than that of polysaccharide(PS) in aerobic environment, and the content of PS was obviously higher than that of PN in anoxic condition.
