The phase of putting terminates to be a cycle of operation.Without sludge recirculation system in SBR technique, reactor volume is little, saved floor space and
Operating cost, in same cycle of operation, reactor is affected little by influent quality water yield change, therefore the anti impulsion load of technique
Ability is strong, but because of its intermittent water inflow and water outlet, in system, SEA LEVEL VARIATION is relatively big, and pool volume utilization rate is low, the utilization of system oxygen
Rate is low.Additionally SBR complex operation is higher to automaticity and operation management personnel's competency profiling.
In biomembrance process processing system, in reactor, it is filled with a number of filler or carrier, can be that microorganism provides
Space is perched in bigger existence, and growth of microorganism is attached to filler or carrier surface forms membranaceous activated sludge.Running
Cheng Zhong, biomembrane constantly increases, updates, comes off, and quantity and the kind of microorganism are more, and sludge concentration is high, therefore reactor
There is the features such as volumetric loading is big, anti impulsion load ability is strong, reaction tank occupation of land is little.But for avoiding the aging activity come off dirty
Mud blocking filler, needs regular backwash, easily causes sludge loss；Be not suitable for the waste water that concentration for the treatment of is high, by arranging mixed liquor
Backflow can dilute water inlet, but limited use；The mud periodically discharged need to realize mud-water separation by the sedimentation tank separately set, and needs to increase
Structures.
Therefore, for solving above-mentioned technical problem, the reaction precipitation integrated aerobic fluidisation of a kind of innovation of necessary offer
Bed, to overcome described defect of the prior art.
[utility model content]
For solving the problems referred to above, the purpose of this utility model be to provide a kind of take up an area little, operational management convenient, impact resistance
