河北东部平原靠近渤海的沧州地区,由于浅层地下水苦咸,深层地下水高氟,农村饮用水质严重不达标。为了改善饮水状况,近年来该市采用电渗析与反渗透技术进行除盐、降氟,实施农村分质供水,大大提高了人们的生活饮用水质量。通过两种除盐、降氟技术的应用实例,分析比较了两种技术设备的水质处理效果,为进一步推广应用提供技术参考。
The eastern plain of Hebei Province is near Cangzhou in the Bohai Sea. Due to the bitterness of shallow groundwater and the high fluoride in groundwater, the quality of drinking water in rural areas is not up to standard. In order to improve the status of drinking water, electrodialysis and reverse osmosis technologies have been used in the city for desalination and fluoride reduction in recent years. The implementation of water supply in rural areas has greatly improved people’s drinking water quality. Through two application examples of desalination and fluoride removal technology, the water treatment effects of two kinds of technical equipment were analyzed and compared, providing technical reference for further popularization and application.
