多孔超滤膜深度处理黄河水的研究

考察了Filcore七孔超滤膜深度处理黄河水的效能。结果表明,经过3个月的中试,膜组件运行稳定,在产水量为4.2 m3/h、进水浊度约为4 NTU的条件下,七孔超滤膜的出水浊度基本在0.2 NTU以下,出水SDI值基本在1.2以下,跨膜压差保持在0.02 MPa左右,膜通量为84 L/(m2.h),产水率达91.7%以上,且电耗和药耗都较低(电耗仅为0.103 kW.h/m3),膜组件未出现气泡、断丝等现象。由此可知,Filcore七孔超滤膜具有良好的抗污染性和透水性,且膜丝的机械强度较高,出水水质满足反渗透的进水要求,用于黄河水的深度处理是可行的。

Advanced Treatment of Yellow River Water by Porous Ultrafiltration Membrane

The advanced treatment efficiency of Yellow River water by Filcore porous uhrafihration membrane was investigated.During the three months experiment, the membrane works well.When the water production is 4.2 m~3/h, and the influent turbidity is 4 NTU, the effluent turbidity of Fileore mem-brane is below 0.2 NTU, the effluent SDI is below 1.2, the TMP is about 0.02 Mpa, the flux is 84 L/ The Filcore membrane is proved to have good anti-fouling, permeability and high mechanical strength performance.The outflow quality meets the inflow requirement of the reverse osmosis.It is feasible for Fileore membrane in advanced treatment of Yellow River water.
