Description
Technical field:
The invention belongs to sewage disposal, environmental protection technical field, be specifically related to a kind of reactor for hydrolysis and acidification.
Background technology:
At present in sewage disposal technology, general acidication technology is UASB and various improved form thereof, and it is even to ensure water distribution that it all needs to lay complicated water distribution system, fully the contacting of sewage and mud.In the practical engineering application, the water distribution line clogging easily takes place in the water distribution system complexity of traditional hydrolysis acidification technique, produces short stream and channel, thereby causes treatment efficiency to descend.
Summary of the invention:
The present invention is directed to the deficiency that general reactor for hydrolysis and acidification exists, design a kind of peripherally-distributed water deflection composite reactor for hydrolysis and acidification, adopt the peripherally-distributed water system, guaranteed the homogeneity of water distribution; Prolong streamline by traverse baffle is set, and adopt the acidication bacterium to suspend and contact growth phase bonded composite system and improved reactor for treatment usefulness, the minimizing occupation of land.
Technical scheme of the present invention is as follows:
This reactor comprises pond body, filler, water inlet pipe and rising pipe etc., and this reactor is made up of three grades of concentric(al) circless, is divided into outer shroud reaction zone, interior ring reaction zone and central reaction district.Wherein: the outer shroud reaction zone is provided with cowling panel in the outer part, the commutating zone and the inboard flow lifting type reaction zone that the outer shroud reaction zone are divided into the outside, be that outer shroud reaction zone periphery has a circle distributing trough above commutating zone, water inlet pipe inserts distributing trough, the distributing trough bottom land is communicated with the commutating zone of below, and the cowling panel bottom is communicated with the flow lifting type reaction zone; Between outer shroud reaction zone, interior ring reaction zone and central reaction district, traverse baffle is set, make water successively baffling enter in the ring and the central reaction district; On top, central reaction district spout is set, connects rising pipe; All be furnished with the suspended sludge bed in outer shroud reaction zone, interior ring reaction zone and bottom, central reaction district, divide into bucket and shore pipe, the middle part is provided with the medium-soft combined stuffing.
Treating processes: sewage is introduced into the distributing trough of outer shroud reaction zone periphery, the water distributing pore of evenly offering by its bottom land, make sewage evenly flow into the commutating zone of bottom, after the rectification energy dissipating, flow into reaction zone, baffling is by outer shroud, interior ring and central reaction district successively, after after the going out chute and collect of top, central section, by rising pipe water is discharged.The flow lifting type reaction zone has the characteristics of UASB and AF simultaneously, sewage enters from reactor bottom, the suspended sludge layer of the Sludge Bed of at first upwards flowing through, then, the reaction zone middle part of flowing through and being provided with semi soft packing, under the condition of no special stirring facility, further enhancement microbiological contacts with matrix, and prolonged reaction process by the baffling mode, strengthen to greatest extent hold back, absorption and microbial metabolism effect, be micromolecular organism with macromolecular hydrolysis of organic matter and organic pollutant in the sewage carried out to a certain degree degraded.
In addition, each reaction zone bottom is provided with bucket storage mud, and regularly opens the mud valve spoil disposal.
Above-mentioned reactor compared with prior art has following characteristics:
1. peripherally-distributed water is uniform and stable, does not stop up
This reactor adopts the water distribution mode of circumferential water feed, loop reactor periphery cloth tank outside, make water distribution more even, pass through rectification energy dissipating in commutating zone again, water distributing pore by the cowling panel bottom flows out, need not complicated pipeline water distribution system like this, also do not have the sorrow of water distribution system obstruction, make water distribution system more stable.
2. the current baffling is popular, has increased reaction process
Traverse baffle is set in reactor, and sewage baffling successively passes outer shroud, interior ring and central reaction district, has prolonged streamline, the interior current of each ring are tending towards mixing fully in the reactor, and integral body is tending towards the plug-flow fluidised form, has improved capacity utilization, has improved the treatment efficiency of system.
3. make up microorganism composite growth system, improved treatment efficiency and capacity of resisting impact load
The combined type system that is made up of suspended sludge bed and semi soft packing is set in each reaction zone, having strengthened mud contacts with matrix, make and keeping higher suspended sludge concentration in the reactor, further increase microbial biomass in the system, improved reactor for treatment usefulness and capacity of resisting impact load.
4. low, convenient management is taken up an area of less, invested to technology
This treatment facility utilizes reactor wall altogether with becoming one of technique unit treatment facilities such as acidication, mud decrement, precipitations, has significantly reduced one-time investment and occupation of land.The Inlet and outlet water Continuous Flow has the characteristics of convenient operation and management.
