膜法水处理技术在农村饮水安全中的应用研究

膜法水处理技术已经成为西部缺水地区进行苦咸水淡化、解决生活饮用水的主要方法之一。本文讨论了在农村饮用水处理中的几种膜工艺流程,分析了农村饮水处理中8套反渗透或纳滤膜苦咸水淡化系统的工艺参数。结果表明膜法淡化高含盐量苦咸水,出水水质均可达到或优于国家生活饮用水卫生标准,可以解决缺水地区的生活饮用水问题。

Study on Application of Membrane Water Treatment Technology in Rural Drinking Water Safety

The membrane water treatment technology has become one of the major methods for desalinating brackish water and solving drinking water in western region with water deficiency. Several membrane process flows in rural drinking water treatment are discussed in the paper. The process parameters of eight sets of reverse osmosis or nano-filtration membrane brackish water desalination system in rural drinking water treatment are analyzed. The results show that membrane method can be used for desalination of brackish water with high salt content, outflow water quality can reach or exceed national drinking water standards, and domestic drinking water problems in the region with water shortage can be solved.
