8. aerobic biochemical reaction member water outlet use annular interception net, interception net three dimensional designs, overall homogeneous solid perforate,
Effectively it can prevent filler from blocking.
9. High-rate sedimentation unit is located at circular processor center, if with sludge settling plate, water leg, distribution channel, mud-collecting slot,
Compact to design, it is ensured that to go out that aqueous suspension is lower, water outlet is more uniform.
10.MBBR techniques have the advantage of both conventional fluidization bed and biological contact oxidation process concurrently, by the exposure in aeration tank
The castering action of gas and current makes carrier be in fluidized state, and then forms the life of the activated sludge and apposition growth of suspension growth
Thing film, this allows for moving-bed biofilm and has used whole space reactor, gives full play to both attachment phase and suspended phase biology
Superiority.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
