摘要采用纯水和浓盐水之间的压力延迟渗透（PRO）系统，研究了中空纤维组件的盐度发电。纯水和浓盐水由区域污水处理设施和海水淡化（海水反渗透[SWRO]）工厂提供。为了使纯水侧上膜表面附近的浓差极化的影响最小化，组件中的开放端口的数量从3个增加到4个，并且发现该修改是有效的，因为通过第四端口离开组件的非渗透性纯水通过膜从盐水侧冲洗泄漏的盐。我们的原型PRO工厂在2.5 MPa的水压差和38%的纯水渗透到盐水中时获得了最大的输出功率密度，7.7 W/m2。采用低压反渗透膜与臭氧氧化混凝沉淀相结合的方法去除纯水中的有机污染物，取得了较好的效果。喂...
Abstract Salinity power generation using hollow fiber modules was examined using the pressure-retarded osmosis (PRO) system between pure water and concentrated brine. Pure water and concentrated brine were supplied from a regional sewage treatment facility and sea water desalination (sea water reverse osmosis [SWRO]) plant. To minimize the effect of the concentration polarization near the membrane surface on the pure water side, the number of open ports in the module was increased from 3 to 4 and that modification was found to be effective because non-permeating pure water, which left the module through fourth port, flushed leaked salt from the brine side through the membrane. Our prototype PRO plant got the maximum output power density, 7.7 W/m2 at a 2.5 MPa hydraulic pressure difference and a 38% permeation of pure water into the brine. To remove the organic foulant in the pure water, a low pressure Reverse Osmosis (RO) membrane and coagulation–sedimentation method with ozonation showed good results. Ho...
