摘　　要：　就浓水排放方式和进水水质对EDI膜堆运行的影响、膜堆的强制再生以及连续运行的稳定性等进行了详细研究。结果表明,浓水排放方式及进水水质对产水水质无影响,但采用浓水循环的方式可降低能耗;在要求的进水水质范围内,膜堆能顺利完成再生过程;膜堆运行稳定,产水电阻率一直在15MΩ·cm以上。Study was made on the effect of concentrated water discharge mode and influent quality on EDI membrane stack operation,the forced regeneration of membrane stack,and stability in continuous operation.The result shows that concentrated water discharge mode and influent quality have no effect on effluent quality.However,use of concentrated water recycle can result in the reduction of energy consumption.In the case of influent meeting the requirement,membrane stack can achieve successfully the regeneration process,with steady operation and resistivity of effluent over 15 MΩ·cm.
