异养硝化微生物菌剂及其好氧颗粒污泥的脱氮试验

, 2009
在3个相同的反应器(No.1、No.2、No.3)中,向活性污泥中投加异养硝化微生物菌剂,以批次试验和SBR试验的方式,研究了异养硝化微生物菌剂对模拟废水的处理效果.结果表明,该菌剂可以大幅度提高活性污泥对氨氮和COD的去除率.批次运行试验中,反应器No.1运行3d,氨氮去除率大于98.11%,COD去除率大于99%.该投加菌剂的活性污泥每克干污泥的脱氮能力为15.77mgd-1.以SBR方式运行16d的试验中,可能是由于功能菌株的流失导致3个反应器的脱氮效果有逐步降低的趋势 ...

三种戊型肝炎诊断试剂可靠性的研究

, 2004
目的 评价不同戊型肝炎诊断试剂对临床急性戊型肝炎诊断的可靠性。 方法 用273份健康人血清和525份肝炎患者血清对三种戊型肝炎诊断试剂进行比较。 结果 E2-IgM试剂用于急性戊型肝炎诊断的特异度为100.0％,显著优于GL-IgM试剂(96.7％)和GL-IgG试剂(85.4％)。E2-IgM、GL-IgG试剂用于急性戊型肝炎诊断的灵敏度(分别为97.9％、93.8％),均显著高于GL-IgM(72.9％)。在65例GL-IgM阳性而E2-IgM阴性的患者中,有58例(89.2 ...

甲苯与甲基化试剂制对二甲苯联产低碳烯烃的方法

, 2009
一种甲苯与甲基化试剂制对二甲苯联产低碳烯烃的方法，采用移动床反应工艺，在反应器顶部连续加入颗粒状催化剂，随着反应的进行，催化剂逐渐下移，最后自底部连续流出到再生器再生。原料甲苯和甲基化试剂进入汽化器混合气化后进入反应器自下而上(或自上而下)通过催化剂床层，与催化剂进行接触反应。反应后的气体混合产物经反应器顶部(或底部)流出进行分离。产物中对二甲苯在二甲苯异构体中的选择性大于99 wt％，乙烯和丙烯在C1-C5低碳烃中选择性大于90wt％。移动床催化剂活性稳定，可以连续再生 ...
