Embodiment
[0017] Such as figure 1 As shown, the present invention proposes a kind of MBR dual-membrane process integrated equipment for sewage treatment, including aerobic zone 1, anaerobic zone 2, aerobic zone 3, MBR membrane zone 4, clean water tank 5, nanofiltration membrane zone 6 and equipment room. In this embodiment, an ultraviolet sterilizer 7 is connected behind the nanofiltration membrane area 6, and the outlet of the ultraviolet sterilizer 7 is connected to a drain pipe.
[0018] Among them, facultative zone 1, anaerobic zone 2 and aerobic zone 3 are three adjacent open tanks, MBR membrane zone 4 is a closed box connected behind aerobic zone 3, and facultative zone 1, anaerobic zone Oxygen zone 2, aerobic zone 3, and MBR membrane zone 4 are connected sequentially through water inlet pipes, and controllable valves are set in the water inlet pipes to adjust the water output and control the residence time of sewage in different areas. The MBR membrane area 4 is connected to th...
