Said water distributor is looping network formula water distributor.
Said micro-hole aerator is the plate-like micro-hole aerator.
Said flow deflector is inverted conical platform tubular flow deflector.
Said effluent weir is the annular overflow weir plate.
Advantage of the present utility model and beneficial effect are:
1, adopt intermittent aeration, anaerobic-aerobic alternately, can fast culture go out granule sludge, and Reaction time shorten, improve processing efficiency, and the degraded of the removal of COD, denitrogenation dephosphorizing, heavy metal adsorption, toxicant is had more significant effect, and clearance reaches more than 85%.
2, take the effluent recycling technology, liquid in reactor has higher upflow velocity, but and the concentration of effluent recycling dilute sulphuric acid salt and other hazardous and noxious substances, can fully contact between sewage and microorganism, can bear larger organic loading, effectively avoid the generation of the interior dead angle of reactor and short stream.
3, do not need whipping appts, the ascending current with effluent recycling, play abundant stirring action to water body.
4, high hydraulic load and unique water distributor can guarantee at utmost that water distribution is even, and return-flow system can be regulated the pH value at any time, control the stable of pH value, and can play stirring action to sludge blanket, make granule sludge and pollutent fully react, adsorb.
