摘　　要：通过对反渗透后接电去离子过程的实验研究,考察了原水电导率、膜堆电流等因素对EDI产水水质的影响,结果表明:降低原水电导率和浓水流量,适当提高EDI原水的温度和膜堆的操作电流,都可以提高产水水质.By combining electrodeionization with reverse osmosis, the experimental study has been done for the process of EDI. The influence of the raw water conductivity and the electric current on the EDI stack etc. were investigated. The optimal operating conditions of EDI stack were discussed. Decreasing the conductivity of raw water and flow velocity and increasing the raw water temperature, and the electric current of the EDI stack are helpful to improve the product water quality.
