| 摘 要： | 研究了浓缩单细胞藻后超滤膜的几种清洗方法,探讨了物理法清洗的持续时间,比较了3种清洗剂（5.0 mL/L HCl、5.0 g/L NaOH和5.0 g/L NaClO溶液）的清洗效果,以及水温对5.0 mL/L HCl和5.0 g/LNaClO溶液清洗效果的影响。结果表明：过滤单细胞藻后,污染超滤膜的几种清洗方法的最佳清洗时间分别为,用物理法反冲洗30 min,用5.0 mL/L HCl溶液冲洗10 min,用5.0 g/L NaClO冲洗10 min。水温小于30℃时,采用5.0 g/L NaClO溶液清洗效果较好,膜恢复率为95.1%;大于30℃时,采用5.0 mL/LHCl溶液清洗效果较好,最高恢复率为95.9%。 |

| Abstract: | The cleaning methods of ultra-filtration membranes in the concentration proccsses of unicelluar algae were studied,including the effects of period of hydraulic cleaning,chemical detergent in 5.0 mL/L HCl,5.0 g/L NaOH,and 5.0 g/L NaClO solution,and temperature in 5.0 mL/L HCl and 5.0 g/L NaClO solution.The optimul periods of cleaning were found at 30 minutes in physical wash,10 minutes at 5.0 mL/L HCl solution,and 10 minutes at 5.0 g/L NaClO solution in the unicellular alga concentration process.The fouled m... |
