| 摘 要： | 在优势菌生物除铬系统中悬挂表面磁场分别为0～6 mT和0～20 mT的磁片,分别控制磁片之间的磁场强度介于0～4.5 mT和0～14 mT,以未加磁场的对照系统作为参照,考察试验污泥活性的变化.试验结果表明,反应器中磁场强度为0～4.5 mT时,对厌氧活性污泥活性的促进效果较好,最大产甲烷速率(Umax.CH4)达64.3 mL CH4/g VSS·d,比非磁场系统提高20.6%,消耗单位COD产甲烷量为0.140 mL CH4/mg COD,比系统非磁场系统提高70.7%.同时发现了磁场的引入,提高了试验污泥利用COD物质生成甲烷的效率,对于低有机负荷重金属废水的生物净化尤其意义重大.

| Abstract: | By setting magnetic pieces in the Cr removal sludge system containing effective strains, magnetic field of 0~4.5 mT and 0~14 mT between pieces could obtained, and the verities of the given anaerobic sludge activity were studied, compared with the control. The results showed that the magnetic field intensity of 0~4.5 mT improved the activity of given sludge more effectively, both Umax.CH4 and methane producing volume per COD reached 64.3 mL CH4/g VSS·d and 0.140 mL CH4/mg COD, compared with the control, which increased by 20.6% and 70.7%, respectively. Meanwhile,it was found that magnetic field increased the efficiency of anaerobic sludge activity on transferring COD of wastewater to methane. The results were significant for the bio-treatment of the low organic load wastewater containing heavy metals. |
