Reactor.
【Background technology】
The waste water that MSW Incineration Plant landfill leachate is generated essentially from precipitation and the fermentation of dumping process.
Such waste water organic composition is complicated, concentration is higher, and the rubbish for burning banks up fresh diafiltration caused by 3~7d in storage hole
Liquid does not contain a large amount of polycyclic aromatic hydrocarbon, phenols and amino benzenes compounds etc. still wherein by prolonged anaerobic fermentation process
Hardly degraded organic substance.Some researches show that analyze Components of Organic Pollutants in landfill leachate, detect garbage filter altogether
Main 63 kinds of organic pollution in liquid, confidence level have 34 kinds 60% or more.Wherein, 6 kinds of alkane alkene, 19 kinds of carboxylic acids, ester
5 kinds of class, 10 kinds of alcohol, phenols, 10 kinds of aldehyde, ketone, 7 kinds of amides, a kind of aromatic hydrocarbons, other 5 kinds.
Upflow anaerobic sludge blanket process-filtering layer reactor have higher treatment effeciency, operation energy consumption is low, surplus sludge volume is small
The advantages that, it is commonly applied to landfill leachate treatment.Due to needing certain upflow velocity in anaerobic reactor, usually by following outside
Loopback stream stir or is stirred agitation to the liquid in reactor using the blender being placed in immediately below in reactor, makes
Liquid maintains preferable motion state in reactor.But since the calcium ions and magnesium ions concentration contained in percolate is high, using outer
Circulating reflux is stirred, circulation pipe Louis fouling, it is difficult to clean；It is carried out under liquid using the blender immediately below in reactor
Blender stirs, and the easy fouling such as internal guide rod, mixing part is taken out repair and is more troublesome, and the normal fortune of processing system is affected
Row, is unfavorable for the continuous operation and steady production of anaerobic reactor.
In view of this, by improving or improveing, enable to that mixing effect is good, stabilization of equipment performance is good and is easy to obtain
The anaerobic reactor of maintaining mixing part, be practitioner institute urgently desirably.
【Utility model content】
The technical problem to be solved by the utility model is to provide a kind of anaerobic reactors of side-feeding type stirring, can be compared with
Biochemical dead angle is reduced in big degree so that Biochemical Treatment is more excellent, and stabilization of equipment performance is good, is easy to blender
Structure carries out maintaining.
The utility model is to solve above-mentioned technical problem by the following technical programs：A kind of anaerobism of side-feeding type stirring is anti-
Device, including the reacting tank body of an anaerobic reactor and a rabbling mechanism are answered, one is equipped with successively from top to bottom in the reacting tank body
Settling section, a packing area and a sludge reaction area, and the water inlet of the reacting tank body is set to the bottom end in sludge reaction area；It is described
Rabbling mechanism include an impeller, one with water inlet direction agitating shaft disposed in parallel and a motor, the impeller and reacting tank body
Water inlet is oppositely arranged, and the impeller is fixedly installed on one end of agitating shaft, and the agitating shaft is arranged in sludge reaction area
Bottom end and by a sealing element and sludge reaction area sealed set, the other end of the agitating shaft is connect with motor.
Further, the motor is variable-frequency motor.
Further, the motor is installed in a base carrier.
A kind of advantageous effect of the anaerobic reactor of side-feeding type stirring of the utility model is：
By the specific setting of rabbling mechanism, biochemical dead angle can be largely reduced, that is, there is preferably stirring to imitate
Fruit so that Biochemical Treatment is more excellent, and stabilization of equipment performance is good, is easy to carry out maintaining to rabbling mechanism, from
And effectively save cost.
【Description of the drawings】
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is a kind of schematic diagram of the anaerobic reactor of side-feeding type stirring of the utility model.
【Specific implementation mode】
Referring to Fig. 1, a kind of anaerobic reactor 100 of side-feeding type stirring of the utility model, including an anaerobic reactor 100
Reacting tank body 1 and a rabbling mechanism 2, be equipped with a settling section 3,4 and of a packing area in the reacting tank body 1 successively from top to bottom
One sludge reaction area 5, and the water inlet 11 of the reacting tank body 1 is set to the bottom end in sludge reaction area 5.
The rabbling mechanism 2 includes an impeller 21, one and water inlet direction 22 and one motor 23 of agitating shaft disposed in parallel, institute
It states impeller 21 and the water inlet 11 of reacting tank body 1 is oppositely arranged, and the impeller 21 is fixedly installed on one end of agitating shaft 22, institute
It states agitating shaft 22 and is arranged in the bottom end in sludge reaction area 5 and by a sealing element 24 and 5 sealed set of sludge reaction area, wherein
Sealing element 24 use mechanical seal, it can be ensured that good sealing effect and service life, the other end of the agitating shaft 22 with
Motor 23 connects.
Wherein, motor 23 selects variable-frequency motor, is capable of providing stable stirring power, and subtract by the frequency conversion of motor 23
Speed controls speed of agitator；And motor 23 is installed in a base carrier 25, and stable support is provided for equipment.
When the utility model operation, landfill leachate enters via water inlet 11 in reacting tank body 1, while starting motor
23, motor 23 is rotated via 22 impeller 21 of agitating shaft, thus by landfill leachate and sludge suspension floor in sludge reaction area 5
It is inside sufficiently stirred, and because of the specific installation settings of impeller 21, biochemical dead angle can be reduced, under upflow velocity, sludge reaction
Anaerobic grain sludge can be formed on 5 bottom of area, due to the anaerobic effect of anaerobe, produce biogas, biogas carry mud and
Water enters packing area 4, and the sludge in water body obtains effectively catching in packing area 4, and mud can be adsorbed on the filler surface of packing area 4,
Biomembrane, further organics removal are formed, the biomembrane to fall off is deposited to the discharge of 1 bottom of reacting tank body, and water body is then through filling out
Expect the separation of the realization water, gas, mud of the settling section 3 of 4 top of area；Since most of structure of rabbling mechanism 2 is all in retort
The outside of body 1, this makes it possible to not empty percolate in reacting tank body 1 or rabbling mechanism 2 be not transferred out of reaction
Rabbling mechanism 2 is repaired or replaced in the case of tank body 1, decreases influence of the high rigidity percolate to component fouling,
Effectively save use cost or maintenance cost.
In summary, the utility model, can be largely less biochemical dead by the specific setting of rabbling mechanism 2
Angle has better mixing effect so that Biochemical Treatment is more excellent, and stabilization of equipment performance is good, is easy to stirring
It mixes mechanism 2 and carries out maintaining, to effectively save cost.
