The utility model provides a resourceful treatment system for organic wastewater with high salt content. The resourceful treatment system comprises an adjusting tank, a high-density sedimentation tank, an electro-Fenton unit, a clarification tank, an ultrafiltration unit, a nanofiltration unit and a first evaporative crystallization unit which are connected in sequence, wherein a water outlet of the high-density sedimentation tank is communicated with a water inlet of the electro-Fenton unit, a water outlet of the clarification tank is communicated with a water inlet of the ultrafiltration unit, a high-salinity wastewater outlet of the ultrafiltration unit is communicated with a water inlet of the nanofiltration unit, and a water outlet of the nanofiltration unit is communicated with a water outlet of the nanofiltration unit. And a monovalent salt wastewater outlet of the nanofiltration unit is communicated with a water inlet of the first evaporative crystallization unit. According tothe utility model, the tr
