Mineral recovery and zero discharge process for high-salt high-organic matter wastewater

The invention discloses a mineral recovery and zero discharge process for high-salt high-organic matter wastewater. According to the mineral recovery and zero discharge process, an adjusting tank is adopted to stabilize water quantity; suspended matter in wastewater is precipitated by adopting a coagulative precipitation tank; organic matter in the wastewater is oxidized by adopting a Fenton reaction tank; membrane distillation inlet water is pretreated by adopting an ultrafiltration unit; most of pollutants in the wastewater are removed by adopting a membrane distillation process, so that aneffluent reaches the recycling or discharging standard; and minerals in concentrated water are separated out by adopting a cooling crystallization process to achieve the purpose of mineral recovery. No pollutants are discharged in the process, and the purpose of mineral recovery is achieved through a cooling crystallization process. Through the process provided by the invention, the problems of mineral recovery and zero e
