The invention relates to a near zero emission process of salt-containing waste water. The process specifically comprises the following steps of: 1) pretreatment, namely, removing part of COD (Chemical Oxygen Demand), suspended solids, hardness and the like from raw water; 2) electric absorption, namely, removing inorganic salt in pretreated partial water, wherein concentrated water generated in the process and part of oxidized waste water which is not subjected to electric adsorption treatment enter into a membrane filtering system together; 3) treatment in a membrane treatment system, wherein the membrane treatment system mainly comprises ultrafiltration, reverse osmosis and electroosmosis processes; and 4) evaporative crystallization and salty mud treatment process, namely, evaporating and crystallizing concentrated salty water generated by electroosmosis, wherein fresh water generated in the process enters into a water supply system while solids generated in the process enter into the salty mud treatment system. The comprehensive water recovery rate of the near zero emission process can reach 99.5%, so that resource and harmful treatment of the salt-containing waste water is realized.
