摘　　要：从工艺与技术性能方面对多介质过滤、中空纤维膜超滤及旋转平板膜超滤这3种目前在我国农村集中式供水饮用水净化得到广泛使用的净水技术进行了介绍与比较。总体而言,多介质过滤工艺属于传统技术,受前期经济技术水平限制,出水水质远低于另外两种超滤膜净水工艺;旋转式平板膜超滤工艺与中空纤维膜超滤工艺相比,两者出水水质接近,都能在去除大部分有害物质同时保留人体需要的元素,但旋转式平板膜超滤工艺具有后发技术优势,对水源要求低,抗污堵能力强,膜使用寿命更长,综合技术经济指标明显占优,适用于农村集中供水,该项技术也适用于城镇水厂水质提升改造。Multi-media filtration, hollow fiber membrane ultrafiltration and rotating flat membrane ultrafiltration are widely adopted for rural central drinking water purification and supply system. These three kinds of water purification technology were compared in respects of technique and performance. Multi-media filtration is generally traditional technique and limited by former technical and economic level, which leads to the worst water quality. The rest two technologies render similar water quality, capable of removing most harmful substance while keeping the elements required by human body. With the technical advantages of low water source requirements, strong ability of resisting pollution and plugging, long service life of membrane, rotating flat membrane ultrafihration technology is superior in aspects of comprehensive technical and economic indexes, and is suitable for rural central water supply and water quality upgrade of township water plant.
