| 摘 要： | 通过在5组相同型号的SBBR反应器(A、B、C、D和E)内调节进水中的Ca2+含量,研究Ca2+在净水生物膜团聚体培养过程的作用影响.结果表明,进水Ca2+投加浓度为25 mg/L时驯化培养的生物膜团聚体具有较好的抗挤压能力,抗压强度达到了22 N/cm2,密度为1.059 g/cm3,活性微生物的百分含量达到了86.90%,远远高于一般污泥团聚体中的微生物含量.分析运行效果,反应器C和D的生物膜团聚体通过29 d的驯化培养就达到了一个比较好的净水效果,并能维持稳定状态,相比于一般生物膜反应器的驯化时间有所缩短.不同进水负荷条件下氮氮的去除率变化表明,反应器C和D针对不同进水负荷表现出来的适应效果明显优于其他反应器.

| Abstract: | An effective way to cultivate efficient biomembrane aggregates was researched by regulating the Ca2+ concentration of the influent in the five SBBR reactors(A,B,C,D,E).When the Ca2+ concentration of the influent was 25 mg/L,the biomembrane aggregates which were cultivated in the SBBR reactor D had the better anti-extrusion capacity.The average compressive strength of the biomembrane aggregates reached 22 N/cm2,the density was 1.059 g/cm3,and the percentage content of the active microorganisms was 86.90%.The... |
