Description
Technical field
A kind of anaerobic reactor is the utility model is related to, is specifically that one kind is thoroughly mixed type pulling flow type anaerobic reactor.
Background technology
At present, most of waste water of the industry such as food, biology, chemical industry discharge belongs to high concentrated organic wastewater, and anaerobism is anti-
Answer device to be used gradually as a kind of efficient biological membrane processing method, it mainly using microorganism with it is organic in waste water
Thing Contact-sorption decomposing organic matter, has achieveed the purpose that effectively to handle organic wastewater, discarded object.
The anaerobic reactor of wastewater treatment is mainly used for the organic pollution that will contain in waste water, passes through the effect of microorganism
Pollutant is decomposed and forms biogas, sludge etc., so as to achieve the purpose that purification.It is commonly used in the anaerobic reaction of wastewater treatment
Device mainly has：Common anaerobic reactor, full-mixing type anaerobic reactor, pulling flow type anaerobic reactor, up-flow anaerobic sludge blanket are anti-
Answer device, internal-circulation anaerobic reactor, upflow solids reactor, baffled reactor etc..Wherein, with up-flow anaerobic sludge blanket
Reactor is most widely used, it be characterized in being formed in reactor sedimentation function it is good, it is based on methane backeria
Granule sludge, it is thus possible to retain higher sludge concentration in reactor, thus reactor efficiency is higher.But actually make
With but being had the following disadvantages in engineering：First, three phase separator design is considerably complicated, and electrification easily occurs in gas-water interface
Corrosion is learned, therefore makes three phase separator to use resistant material, thus the cost of manufacture of three phase separator is higher, such as
The three phase separator made with stainless steel material, though only 10 years or so its service life, account for whole capital cost of reactor 40% is left
It is right so that the investment of upflow anaerobic sludge blanket reactor is higher.Second, the activated sludge that settling zone settles down is leaned on from gravity
Returning reactor, and waste water is then to flow from bottom to top, and effect of increasing will necessarily be produced to the sedimentation of activated sludge, thus in the past
Gas-solid-liquid separate mode is stated there are the halfway inherent shortcoming of separation of solid and liquid, so as to influence the efficiency of reactor.Third, in order to do
To uniform water distribution, the design requirement of water distribution system must be higher, and otherwise, water distribution is uneven to cause occur dead band in reactor,
It is unfavorable for the raising of reactor load.
And pulling flow type anaerobic reactor has the advantages that simple in structure, energy consumption is low, stability is high, and in recent years using getting over
Carry out more anaerobic reactors.But, in practice, it also has the following disadvantages：Solids is easily deposited in bottom of pond, shadow
The effective volume of reactor is rung, reduces HRT and SRT, efficiency reduces；The reflux of solid and microorganism is needed as inoculum；
Reactor areas/volume is bigger, and the temperature being consistent is difficult in reactor；The crust of thickness is also easy to produce in equipment.
The content of the invention
The utility model is precisely in order to solve above-mentioned technical problem, there is provided one kind is thoroughly mixed type pulling flow type anaerobic reaction
Device, it reinforces the contact between useless Organic substance in water and microorganism, enhances mass transfer effect, and the biochemistry for improving reactor is anti-
Speed is answered, so as to substantially increase the treatment efficiency of reactor, available for SS contents are high and the waste water and high concentration of difficult degradation
Treatment of Organic Wastewater, and fermentate is uniformly mixed, and is not likely to produce crust.
The utility model is achieved through the following technical solutions：
One kind is thoroughly mixed type pulling flow type anaerobic reactor, it is characterised in that including water inlet mixed zone, hydrolysis area, acidifying
Area, the sour methanogenic zone of production, mud-water separating area, each area are separated using hydraulic barrier, are set respectively in hydrolysis area and the sour methanogenic zone of production
Impeller is equipped with, water inlet mixed zone is provided with water entry, and mud-water separating area is provided with EXIT POINT.
The hydraulic barrier is selected from arch hydraulic barrier or disk-and-doughnut shape hydraulic barrier.
The acidification region is provided with spare water entry.
The water entry, EXIT POINT, spare water entry are both provided with valve.
The type pulling flow type anaerobic reactor that is thoroughly mixed is back-shaped arrangement.
The type pulling flow type anaerobic reactor that is thoroughly mixed highly is 5-10 meters.
The utility model has the advantage that as follows relative to the prior art：
1st, organic loading is high, strong shock resistance；
2nd, the residence time is short, and organic loading is higher, therefore, handles the organic wastewater of same scale, required volume
Far less than common anaerobic reactor；
3rd, form stable, which coexists using anaerobic grain sludge and floc sludge, sludge
Sinking speed be more than the rate of climb of sewage, and be equipped with mud-water separating area, therefore the anaerobic reactor can seldom run mud, run
Stablize；
4th, resistance to high load capacity, the unexpected increase of influent concentration or the suddenly change of inflow, can all cause anaerobic reactor
Load impact；Effect of circulation in it, after the waste water of the high concentration of moment enters reactor, big interior circulation can be by high concentration
Waste water rapidly dilutes, so as to reduce impact of the organic loading change to reactor；
5th, multipoint water feeding can be used, further mitigates the impact load of water inlet end；
6th, impeller and hydraulic barrier are employed, fermentate is uniformly mixed, and can efficiently reduce encrustation phenomena.
Brief description of the drawings
Fig. 1 is the structure diagram that the utility model is thoroughly mixed type pulling flow type anaerobic reactor.
Wherein：1- is intake mixed zone, 2- hydrolysis areas, 3- acidification regions, the sour methanogenic zone of 4- productions, 5- mud-water separating areas, 6- into
Water spot, 7- EXIT POINTs, the spare water entries of 8-, 9- impellers, 10- hydraulic barriers.
