摘要:
随着人们对高品质饮用水的迫切需求，常规水处理工艺在保障健康水质方面存在一定的局限性。采用聚醚砜中空纤维纳滤膜作为居民小区前端供水设施进行中试研究，通过分析电导率、溶解性总固体（TDS）、浊度和回收率等指标，建立纳滤系统产水周期、进水压力等最佳运行参数；采用三维荧光光谱和膜比通量分析膜污染机制；通过扫描电镜、X射线光电子能谱以及傅里叶红外光谱，分析出厂水中余氯对膜材料性能的影响。结果表明，在产水周期为60 min、进水压力为0.35 MPa条件下，电导率下降率以及纳滤膜对TDS和浊度的去除率分别达到29.8%、24.0%、71.2%，回收率高达80%~90%。经过8个月的运行，膜污染与产水周期和进水压力呈正相关性，当进水含有余氯时，虽在纳滤膜上检测出少量氯元素，但对膜的运行效能影响较小，中空纤维纳滤膜表现出优异的耐氯性。
Abstract:
With the growing demand for high?quality drinking water, conventional water treatment processes have limitations in ensuring healthy water quality. Pilot-scale studies were conducted using polyether-sulfone hollow fiber nanofiltration membranes as front-end water supply facilities in residential communities. By analyzing parameters such as conductivity, total dissolved solids (TDS), turbidity, and recovery rate, optimal operating conditions including water production cycle and feed water pressure were established. Membrane fouling mechanisms were investigated through three-dimensional fluorescence spectroscopy and membrane flux ratio analysis. The impact of residual chlorine on membrane performance was evaluated using scanning electron microscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. Results showed that under 60-minute water production cycles and 0.35 MPa feed water pressure, the nanofiltration membranes achieved removal rates of 29.8% for conductivity, 24.0% for TDS, and 71.2% for turbidity, with recovery rates reaching 80% to 90%. After eight months of operation, membrane fouling showed positive correlations with water production cycle and feed pressure. Although trace chlorine was detected on the membrane when feed water contained residual chlorine, its impact on operational efficiency remained minimal. The hollow fiber nanofiltration membranes demonstrated excellent chlorine resistance.
