Single-stage non-contact membrane distillation wastewater treatment device and method

Abstract

The invention discloses a single-stage non-contact membrane distillation wastewater treatment device and method. The single-stage non-contact membrane distillation wastewater treatment device comprises an evaporation tower, a membrane distillation assembly, a fan, an evaporation heat exchange assembly, a temperature and humidity adjusting assembly, a cyclone water segregator and a heating assembly, the evaporation tower, the fan, the evaporation heat exchange assembly, the temperature and humidity adjusting assembly and the cyclone water segregator are sequentially connected, and the cyclone water segregator is further connected to the membrane distillation assembly. The membrane distillation assembly is arranged in the evaporation tower and located at the top of the evaporation tower, and the heating assembly is connected to the evaporation tower and used for heating radioactive wastewater in the evaporation tower. The device is used for high volume reduction and deep purification treatment of radioactive wastewater generated by nuclear power station operation and maintenance, nuclear accident emergency, spent fuel reprocessing plant production, hospital radiotherapy and the like.
