Description
One, technical field
This patent is a kind of anaerobic reactor for the high concentration organic sewage processing, belongs to sewage disposal, environment protection, energy-conserving and emission-cutting technology field.
Two, background technology
Because energy-conservation, running cost is low, can produce biogas characteristics such as (energy outputs) that Anaerobic treatment technique has, thus it is generally acknowledged to process for high concentrated organic wastewater and should adopt first anaerobic technique, and then the employing aerobic process is for further processing.
At present, the main technique of anerobic sowage processing has: anaerobic filter (AF), anaerobic fluidized bed reactor (AFB), upflow anaerobic sludge blanket reactor (UASB), expanded granular sludge bed reactor reactor (EGSB), anaerobic internal circulation reactor (IC), anaerobic baffled reactor (ABR) etc.
Anaerobic biofilter (AF) is that an inside is filled with the anaerobic reactor for the filler of microorganic adhesion.Filler is immersed in the water, and microorganic adhesion also has partial suspended between the hole of filler on filler.Sewage flows into anaerobic biofilter, contact with the microorganism of filter material surface, the organic pollutant in the sewage by microorganism hold back, Adsorption and decomposition, to reach the purpose of purification.For the hc effluent of complicated component, filtrate stops up easily.
Filling the carrier that particle diameter is little, specific surface area is large in anaerobic fluidized bed (AFB) reactor, the microbial film that anaerobion forms is grown at carrier surface, and carrier is in fluidized state, has good mass transfer condition, and microorganism easily fully contacts with waste water.For the hc effluent of complicated component, there is the risk that filtrate runs off, filtrate lumps.
The main part of UASB reactor is a packless empty receptacle, is divided into reaction zone and negative area two portions.When reactor moved, waste water entered reactor with certain flow rate from the bottom water distribution system, upwards flowed by Sludge Bed, and feed liquid fully contacts with microorganism in the mud and carries out biological degradation, forms methane, and biogas is constantly emitted with the form of micro-bubble.Micro-bubble holds up mud in uphill process, makes Sludge Bed that obvious expansion be arranged.Along with gas production rate increases, this mixing acts on reinforcement, causes that the Sludge Bed surface slightly is the boiling fluidized state.The mud granule that sedimentation function is not so good or flco form suspended sludge layer in reactor top under the stirring of gas.Gas, water, mud mixed solution rise in the triphase separator, and biogas is run into reflector and is subjected to deviation in uphill process, pass water layer and enter air chamber, discharge reactor by conduit.Mixed solution after degassed enters the settling region that leave standstill on top, under action of gravity, further carries out solid, liquid and separates, and the mud under the sedimentation is back in the reaction zone by skew wall, makes a large amount of microorganisms of accumulation in the reaction zone, and the processing water of clarification is discharged from the settling region overflow.For the hc effluent of complicated component, the obstruction of water distributor is the problem of often meeting, because the fluctuation of water quality causes the loss of mud also can affect the efficient of reactor.
Expanded granular sludge bed reactor technique (EGSB), waste water enters reactor by the water distributor of bottom, by strengthening Sludge Bed current upflow velocity, strengthen and mix and mass transfer process, improve processing efficiency, obtain higher volumetric loading, have bottom water distribution fault, go out the high risk of water suspension.
The IC reactor is the series operation of two UASB reactors quite up and down, below a reactor have very high organic loading rate, play the bulk processing effect, above the load of a reactor low, play the precision processing effect.IC inside reactor complex structure, design and construction require high.The reactor aspect ratio is large, has increased on the one hand the power consumption of intake pump, has improved working cost; Accelerate on the other hand the current lift velocity, made in the water outlet fine particulates more than UASB, increased the weight of the burden of subsequent disposal.The rising of muddy water mixed solution produces latch up phenomenon easily in its internal recycle, makes the internal recycle paralysis, process result degrades.
The ABR reactor is divided into some compartments by some groups of vertical baffling plates, when processing high-concentration sewage, the compartment of front is take the hydrolysis bacterium as main, and the compartment of back is take methanogen as main, the condition of each compartment is different, for microorganism not of the same race has been created suitable living longevity environment.Because the fluctuation of water quality, when the selectivity accumulation in different compartments of zymophyte, acid-producing bacteria and methanogen was not occured, treatment effect will be greatly affected.
This patent, simple in structure, without stopping up, muddy water mixes fully, and it is extremely low to go out water suspension, for the processing of high-concentration waste water provides a brand-new problem settling mode.

Concrete summary of the invention is as follows: recycle pump 5 is installed on outside the main tank body 1, the mixture that accumulates in the mud of main tank body 1 bottom and sewage enters the entrance of recycle pump 5 by the circulation tube 6 of main tank body 1 bottom, by the top that arrives main tank body 1 after recycle pump 5 pressurizations through circulation tube 6.Intake pump 7 is delivered to raw water pump in the circulation tube 6, and former water, mud, treated sewage obtain mixing in circulation tube 6, and the former water of high density obtains inoculation and dilution, is conducive to the steady running of anaerobic reaction.
In water conservancy diversion reaction tubes 2, in the process that mud and sewage flow downward, because the difference of density compares with sewage, mud will move to the bottom with speed faster, and this velocity contrast will promote contacting of mud and sewage.Owing in the process that the gas that anaerobic reaction produces rises, will produce the mixing effect that continues to mud and sewage, and make both contacts more abundant.
Mud from water conservancy diversion reaction tubes 2 bottoms out after, again accumulate in the bottom of main tank body 1, will again arrive the top of reactors by recycle pump 5.
Sewage from the first reaction chamber 16 bottoms out after, enter formed the second reaction chamber 17 in space between water conservancy diversion reaction tubes 2 outer walls and main tank body 1 inwall, the single step reaction of going forward side by side from bottom to top flows.Because the rising of water is flowed and the rising of the gas that anaerobic reaction produces is overflowed, make the mud in the second reaction chamber 17 be in swelling state, what be conducive to react further carries out.Because sewage upflow velocity and this zone aerogenesis quantitative limitation, the sludge bulking in the second reaction chamber 17 highly obtains restriction, and the concentration of suspension at this top, zone significantly reduces.The top of the second reaction chamber 17 arranges triphase separator 3 and overflow groove 4, triphase separator 3 make gas, water, solid three-phase advance a part from, isolated mud will precipitate downwards, and gas enters the collection chamber 9 at main tank body 1 top, and water outlet enters overflow groove 4 and discharges reactor.
Reactor need not to arrange in vivo water distribution pipe or equipment and reaches water distribution uniformity, and is inner without any pipeline and electrical equipment, avoids chronically maintenance.
The mud of the first reaction chamber 16 is in compulsory suspended state, has guaranteed efficiently finishing of principal reaction, has improved the whole efficiency of reactor.
For processing the high organic sewage of Pollutant levels, the less upflow velocity of the second reaction chamber 17 makes mud-water separation more thorough, effectively guarantees the sludge concentration in effluent quality and the reactor.
