Brief description of the drawings
Fig. 1 is internal-external double circulation anaerobic reactor structural representation of the present invention.
Embodiment
Refer to Fig. 1, a kind of internal-external double circulation anaerobic reactor（Bio-TC anaerobic reactors）, it is characterised in that including：
A set of water distributor is arranged below in one sludge top 101, sludge top 101, water distribution system is constituted with the sludge top 101, to uniform
Water distribution；Three separators 102 of first layer, second layer degassing Sediment Module 103, group are sequentially provided with the reactor from top to bottom
Into the separation of inside reactor two-stage.One tedge 105, the composition internal circulation system of down-comer 106.And outer circulating tube 107 and outer
Circulating pump 108 constitutes external circulating system.
The utility model also includes a degassing tank 104, and the degassing tank 104 is arranged on reactor head；Degassing tank 104 connects
Connect riser 105 and down-comer 106, and top firedamp drainage pipe 109.
Three described separators 102, collection solid, liquid, gas three are located away from one；Described degassing Sediment Module 103, takes off
Gas separates progress with precipitation.
Described three separators 102 of first layer and second layer degassing Sediment Module 103 modularized design, by import PP materials
Material makes.
The biogas that described three separators 102 of first layer and second layer degassing Sediment Module 103 are isolated each is collected
Systematic collection.
In one embodiment of the present utility model, operation principle of the present utility model can be：
Waste water to be processed is needed to enter reactor by reactor bottom pump 110 using efficient water distribution system, via with water system
After water under unified central planning, by the water distribution uniformity of sludge top 101, uniformly mixed with the anaerobic sludge in reactor.Upwardly through sludge bed with
Anaerobic bacteria occurs after biological respinse, and promoting the circulation of qi, three separation of solid, liquid, most of biogas are entered by three separators 102 of first layer
The degassing tank 104 set to tank deck is lifted by biogas tedge 105 herein, the further separation of biogas is carried out, and taken off
Water sludge top water distribution system is flow to by down-comer 106 again, with water inlet again circulation mixes, realize the interior circulation of waste water.
The waste water after three separators 102 of first layer enters sludge suspension layer afterwards.This region belongs to top
Precision processing area, waste water is further processed, and the organic matter that sludge bed has not enough time to degraded is further degraded herein.The essence
Treatment region also has firedamp drainage pipe 111.Here the methane quantity generated is relatively fewer, the unique Sediment Module set by top
Second layer degassing Sediment Module 103 separation of solid and liquid, degassing module are removed after biogas, flow to outlet pipeline water outlet.Anaerobic reactor
One larger gas storage space is arranged at top, it is ensured that biogas more stably enters follow-up methane utilizing system.Filled in addition to reaching
The mixed effect and anti-load impact divided, is provided with circulating pump 108, effluent part is from reactor top circulating line 107 through following
Water is back into water main pipe by ring pump 108, after uniformly being mixed with raw water, then by water distribution system even into reactor,
To adjust the upflow velocity of reactor.This part Hydraulic Circulation is not module bottom by second layer degassing Sediment Module 103
Water is circulated, can keep internal muddy water be sufficiently mixed in the case of without influenceing the separating effect of degassing Sediment Module.
The stripping that the interior circulation of BIO-TC internal-external double circulation anaerobic reactors is produced by biogas, which is acted on, to be produced, without energy consumption both
Circulating effect can be carried out, and three separators 102 of first layer belong to the most part of generation biogas, therefore interior circulation is arranged on
Here.And outer circulation is carried out using circulating pump 108, circulation position is the less sludge suspension layer of sludge quantity, it is possible to use here
Water circulated, successfully manage the water inlet of high concentration, and the waste water basicity after sludge bed is relatively low, water here
Circulation can mitigate the risk of sludge calcification.
In addition, the outer circulation part of the utility model BIO-TC internal-external double circulation anaerobic reactors can be according to waste water and fortune
Row needs are switched over, if internal circulation system is preferably, influent concentration is relatively low, can save energy consumption without outer circulation;When entering
When water concentration is higher or reactor start-up initial stage and reactor activity decline interior circulation effect and be deteriorated, these situations just can be with
Using outer circulation, upflow velocity is controlled by outer circulation, inlet COD concentration is diluted, it is ensured that effective operation of reactor.
The difference of the utility model internal-external double circulation reactor also resides in first layer and the special of second layer separator sets
Meter.First layer, using three separators 102, is efficient air, three piece-rate systems of solid, liquid, and it is larger to be arranged on sludge concentration, biogas
The more bottom of yield is used as three separators 102 of first layer；And be not separated after three separators 102 of first layer
Sludge, plays the effect of further organics removal between one or two layers of separator, afterwards by second layer degassing precipitation mould
The Sediment Module separation of block 103.And second layer degassing Sediment Module 103 is different from three separators 102 of first layer, it uses heavy
Shallow lake module and the mode that separately carries out of degassing module are so smaller or floc sludge has very for reactor upper part particle
Good precipitation and separation effect, it is to avoid the situation of sludge loss.
In summary, by adopting the above-described technical solution, the utility model internal-external double circulation anaerobic reactor is solved
Interior circulation IC reactor cycles effect limitation of the prior art, three separators are to the easy race mud of floc sludge.EGSB is followed outside
Loop reactor outer circulation is single, energy consumption is big, one layer of three separator separating effect are poor, and the more low limitation of volumetric loading is asked
Topic, technology disclosed in the utility model combine internal-circulation anaerobic reactor generation interior circulation power, three be located away from one
High-efficiency type design, while dexterously flexible using outer circulation reactor outer circulation operation operation, efficiency stablizes secure, very
It is suitable for handling high concentration, the big industrial wastewater of variation water quality.
It is only preferred embodiment of the present utility model in summary, not for limiting implementation model of the present utility model
Enclose.The equivalent changes and modifications that i.e. all contents according to present utility model application the scope of the claims are made, all should be of the present utility model
Technology category.
