1超滤运行过程中膜表面亲水性的变化特征显示文摘为了研究膜亲水性在超滤运行过程中的变化规律,采用小试装置,研究了在不同运行状况下的膜接触角变化。结果表明,在长期的运行过程中,膜接触角均不同程度地下降。单独水反冲洗和化学加强反洗对接触角的影响较小。膜接触角在过滤周期内先升高再降低。随着通量的增加,膜接触角逐渐降低。与沉后水相比,活性炭过滤出水更易引起膜接触角下降。随着pH升高,膜接触角会上升。化学清洗使膜接触角增加,当用NaOH清洗时,接触角变化不大;而用HCl和NaClO清洗时,接触角明显增加。总之,膜表面亲水性在运行过程中会发生一定变化,并且受到原水水质、操作参数和反冲洗方式等方面影响。乔铁军 Doris W T AU 张锡辉 2013水处理技术2013,39,6:2
2亚致死剂量UV-C辐照抑制铜绿微囊藻生长的效果显示文摘铜绿微囊藻是中国典型的水华蓝藻。该文研究亚致死剂量短波紫外线(UV-C)辐照对其生长的抑制效果。采用准平行光束仪进行定量辐照处理,用共聚焦激光扫描显微镜进行藻细胞计数,用流式细胞术识别藻细胞膜完整性,三维荧光光谱分析藻蓝蛋白及叶绿a的相对荧光水平。结果表明:对初始密度为106个/mL铜绿微囊藻,UV-C辐照能抑制藻细胞生长,亚致死剂量范围是50-100 mJ/cm^2,抑制效果可以持续7 d。陶益 毛献忠 张锡辉 袁侃 Doris W T Au 2010清华大学学报(自然科学版)2010,50,9:2
