Volume part more than the orifice plate that the mixed flow chamber is comprised of circular outer cylinder and orifice plate, this regional liquid forms the up and down mixed flow under the promotion of passing the orifice plate gas that rises and the waste water that pumps into from reactor head;
2. the standing separation dividing plate is arranged on the position of urceolus top water outlet, by stopping and filteration of this dividing plate, makes the water quality clarification;
3. circular up-flow cylinder bottom has the identical circular pod apertures of several diameters evenly to distribute along a circle, enters the passage of up-flow chamber from circular up-flow cylinder bottom as falling stream chamber fluid;
4. 1/3rd zones, circular shunt cylinder top have the identical circular pod apertures of several diameters evenly to distribute along a circle, and circular shunt cylinder bottom section also has the identical circular pod apertures of several diameters evenly to distribute along a circle;
5. described complex carrier is respectively suspension ball and granulated carrier.
Above-mentioned granulated carrier is to choose any one kind of them in quartz sand, coal ash, gac and polyurethane particles or several.
Different wastewater treatment patterns can be moved in three Room of above-mentioned biological fluidized-bed reactor, can adapt to the processing requirements of different waste water:
When 1. opening air pump, the up-flow chamber is the oxygen consumption tupe with falling the stream chamber, and the mixed flow chamber is anaerobism or anaerobic treatment;
When 2. turning off air pump, the up-flow chamber is the anaerobic treatment pattern with falling the stream chamber, and the mixed flow chamber is anaerobism or anaerobic treatment.
Compare with traditional fluidized-bed reactor, the present invention has following apparent characteristics and advantage:
