| 摘 要： | 用抗污染超滤膜聚偏氟乙烯(PVDF)合金膜、高压纳滤膜(聚芳香酰胺膜)处理含Cr6+,Ni2+,Cu2+重金属离子的电镀废水.抗污染PVDF合金超滤膜在经过三次电镀废水处理后,膜通量由4.2 L/h降为3.6 L/h,透过液的透光率大于96.3%,可去除大部分有机物.超滤透过液经过纳滤处理后,纳滤透过量由1.8 L/h降低为1.7 L/h,并且在1.5 h后基本保持不变,对Cr6+,Ni2+,Cu2+的去除率达97%以上.电镀废水经抗污染超滤膜-高压纳滤组合工艺处理,可达电镀清洗水标准,回用率达到85%.

| Abstract: | PVDF-PES ultrafiltration membrane and high pressure nanofiltration membrane(aromatic polyamides membrane) with good antifouling property were used to treat electroplating wastewater containing Cr~(6+),Ni~(2+) and Cu~(2+).The permeate flux of PVDF membrane decreased from 4.2 L/h to 3.6 L/h after the membrane was used for three times and the transparence at 600 nm of permeate was higher than 96.3%,which indicated that most of organic substances have been removed by PVDF membrane.After that,the ultrafiltration... |
