【摘要】 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。更多还原

【Abstract】 Cangzhou locates in the eastern plain of Hebei and near the bohai sea.The quality of rural drinking water in the region seriously exceeds standard by the brackish shallow groundwater and high-fluoride deep groundwater.To change the situation,electrodialysis(ED)and Reverse Osmosis(RO)techniques are adopted for dual water supply,to improve the quality of people’s drinking water.In this paper,through application examples of the reducing fluoride and desalting technology,the effects of water quality treatment by ED and RO techniques are compared and analyzed,which may provide technical reference for further popularization and application.更多还原
