中文摘要:
      构建一种新型膜污染控制技术­­——含氯水反冲洗工艺,以超滤膜分离技术为理论基础,考察加氯水反冲洗工艺对超滤膜压力变化情况,研究含氯水反冲洗对超滤膜污染的去除效能。结果表明:经过40个小时的运行超滤膜跨膜压差由初始时的39kPa增加至56kPa,增加了近80%。随着周期加氯反冲洗跨膜压差以及运行通量逐渐得到恢复,表明低浓度含氯水反冲洗对腐殖酸造成的膜污染具有明显的清洗效果
英文摘要:
      Building a new type of membrane pollution control technology is chlorinated backwash water craft, its theoretical foundation is ultrafiltration membrane separation technology. Study of chlorinated water backwash process on ultrafiltration pressure changes, Research on chlorinated backwash water ultrafiltration pollution removal efficiency. The results show that 40 hours of operation of the ultrafiltration, membrane transmembrane pressure increased from the initial time 39kPa to 56kPa. With the backwash cycle chlorination transmembrane pressure and running flux gradually recovered, indicating low consistency chlorine water backwash on membrane fouling caused by humic obvious cleaning effect.
