Its technical scheme does, the air film bio-reactor that exposes oneself, comprise hollow from biological runner of aeration and MBR membrane module, the MBR membrane module is fixed on the inside from aeration biology runner.In the present technique scheme, the MBR membrane module is fixed on from the biological runner of aeration inner, and forms membrane bioreactor from inner cooperation of the biological runner of aeration, compact construction, saving space.
Saidly fixedly form by a plurality of blodiscs are range upon range of from the biological runner of aeration, blodisc stacked together is vertically through the fixed link connection.Through fixed link be fixedly connected from the biological runner of aeration, sound construction, blodisc is difficult for loosening, equipment life is longer.
Two ends from the biological runner of aeration are fixed with diaphragm side clamping plate, are fixed with driving chain wheel on the clamping plate of an end, and hollow axle connects together the clamping plate at two ends.Adopt the driving chain wheel structure, the driving of convenient biological runner driven device.
Outside surface from the biological runner of aeration is fixed with the mud scraping blade.Adopt the mud scraping blade can in time remove the mud that is deposited in biological wheel surface, keep biological runner and run well.
The MBR membrane module is tubular fibre formula/board-like/tubular membrane component.Adopt different membrane modules as required, better adapt, improve processing efficiency with biological runner volume inside.
A plurality of MBR membrane modules are fixed on the hollow axle of the biological runner of aeration through support.Adopt support that the MBR membrane module is fixedly connected, and the MBR membrane module is fixed on from the biological runner of aeration inside, guarantee that membrane module does not move with biological runner, prevent rocking of membrane module, keep the stable of membrane bioreactor.
Said MBR membrane module also is connected with rising pipe, and rising pipe penetrates hollow axle, and is extended by hollow axle, realizes biological runner center water outlet.
The utlity model has following beneficial effect: (1) from the built-in membrane module of the biological runner of aeration, inside forms membrane bioreactor, has improved the compactedness of structure, saves the space, and floor space is little; (2) from the biological runner of aeration sewage is carried out the early stage processing subsequent and just get into membrane bioreactor, alleviated pollution, saved working cost film; (3) be that membrane bioreactor provides oxygen from the biological runner of aeration, do not establish special-purpose aerator, reduce cost of equipment and running cost; (4) do not establish the backwash device, realize energy-conservation effect, further reduce cost of equipment and running cost.
