  • 摘要: 分别采用2种相同孔径不同材质的膜材料(39 μm尼龙,39 μm涤纶)进行死端过滤与错流过滤实验,以考察微网材质对动态膜(DM)形成的影响。死端过滤实验结果表明,尼龙和涤纶微网均可获得超过99.7%的悬浮物(SS)截留率,而涤纶微网比尼龙微网更容易形成致密的动态膜;错流过滤实验结果表明,尼龙和涤纶微网最终出水浊度均小于20 NTU,同时发现,涤纶网在动态膜形成过程中,压力上升较慢,但动态膜更致密,因此,出水效果更好。
    Abstract: In order to investigate the effects of mesh material on dynamic membrane formation, the performance of two kinds of meshes (39 μm-nylon and 39 μm-dacron) was studied in dead-end filtration and cross-flow filtration test. According to dead-end filtration test, it was found that more than 99.7% of the suspended solids (SS) were retained by two kinds of dynamic membrane (DM). Compared with nylon mesh, dacron mesh could be conducive to form more thick and compact DM layer. However, cross-flow filtration test shows that the final effluent turbidity of both dacron mesh and nylon mesh DM was less than 20 NTU. Meanwhile, it was found that during the formation of DM layer, the transmembrane pressure increase rate of DM of dacron mesh is less than that of nylon mesh, while the formation of more compact DM layer by dacron mesh results in higher effluent quality.
