摘　　要：为保障饮用水安全,探究了浸没柱式中空纤维超滤膜在高于常规运行压力(-0.02 MPa)条件下对大肠杆菌的截留性能。实验选用天津膜天膜科技股份有限公司的溶液纺丝法膜组件和同质增强型复合膜组件,分别于-0.04 MPa和-0.06 MPa的运行压力条件下进行大肠杆菌截留实验,结果表明,津膜科技溶液纺丝法膜组件SF-635和同质增强型复合膜组件ST-635在高于常规运行压力条件下运行,对大肠杆菌的截留性能良好,膜产水中未检出总大肠菌群,在高运行压力条件下仍能可靠保障饮用水的安全。In order to guarantee safe drinking water and research the retention characteristics of submerged hollow fiber ultrafiltration membrane under higher conventional pressure(-0.02 MPa),in this study,melting spinning method mem-brane(SF-635)and composite membrane(ST-635) of Tianjin Motimo Membrane Technology CO.,LTD.will operate under-0.04 MPa and-0.06 MPa to filtration. The results show that the membrane could withstand high pressure and intercept bacterial performance was good. Membrane can still guarantee the safety of drinking water under high pressure.
