Device for removing iron and manganese in underground water through manganese sand fluidized bed-ultrafiltration and ultraviolet disinfection

The invention relates to a device for removing iron and manganese from underground water through manganese sand fluidized bed-ultrafiltration and ultraviolet disinfection. The device for removing the iron and manganese from the underground water through the manganese sand fluidized bed-ultrafiltration and ultraviolet disinfection comprises a control chamber, a manganese sand fluidized bed-ultrafiltration chamber and an ultraviolet disinfection chamber, a water inlet pipe is arranged in the manganese sand fluidized bed-ultrafiltration chamber, a rotary membrane turntable and a stirring device are arranged in the manganese sand fluidized bed-ultrafiltration chamber, manganese sand in the manganese sand fluidized bed-ultrafiltration chamber is fluidized under the stirring action of the rotary membrane turntable and the stirring device, oxides formed by oxidizing iron and manganese ions in the underground water are intercepted by the rotary membrane turntable, suspended-state ferromanganese oxides and manganese sand are separated due to different sedimentation performances, and ultrafiltration water coming out from the manganese sand fluidized bed-ultrafiltration chamber is disinfected by the ultraviolet disinfection chamber. The integrated device is simple in structure and easy to operate, backwashing does not need to be carried out, manganese sand utilization rate is high, water treatment cost is low, iron and manganese can be removed at the same time, removal efficiency is high, and effluent quality can stably reach the drinking water standard for a long time.
