Background technology
In sewage treatment industry, anaerobic reactor is the treating plant of using always, but has certain problem the user at present, and promptly structure is comparatively complicated, the cost height, and floor space is big, has increased the burden of enterprise.
Summary of the invention
The purpose of this utility model is exactly to take up an area of problems such as big in order to solve present anaerobic reactor cost height, provide a kind of have simple in structure, easy to use, the treatment efficiency height has dwindled the volume of reactor, reduce construction investment, saved the anaerobic reactor of advantages such as floor space.
For achieving the above object, the utility model adopts following technical scheme:

Described tank body lower side is provided with manhole; Inner tank wall at anaerobic zone I and anaerobic zone II is respectively equipped with interior cat ladder; Tank wall at anaerobic zone II is provided with stopple coupon, and the gas-water separation pipe; Tank wall at anaerobic zone I is provided with temperature tube.
The aspect ratio of described tank body is 4-8.
The characteristics of HE-IC anaerobic reactor structure of the present utility model are to have very big aspect ratio, generally can reach 4-8, and the height of reactor reaches about 20m.Whole reactor is formed by stacking by anaerobic zone I and anaerobic zone II.A gas, solid, liquid triphase separator are respectively established in the top of each anaerobic zone.First step triphase separator mainly separates the natural pond G﹠W, main separated sludge of second stage triphase separator and water, and water inlet and returned sluge mix at anaerobic zone I.Anaerobic zone I has the organic ability of very big removal, and the waste water that enters anaerobic zone II can be proceeded to handle, and to remove the residual organic substances in the waste water, improves effluent quality.
It is 5 districts that the HE-IC anaerobic reactor from bottom to top is divided into: mixing zone, anaerobic zone I, anaerobic zone II, settling region and gas-liquid separation zone.
The mixing zone: the mud mixture that reactor bottom water inlet, granule sludge and gas-liquid separation zone reflux mixes in this district effectively.
Anaerobic zone I: the mud mixture that the mixing zone forms enters this district, and under the high concentration sludge effect, most of organism is converted into biogas.The violent disturbance of mixed solution upwelling and biogas makes the interior mud of this reaction zone be expansion and fluidized state, has strengthened the contact of muddy water surface, and a part of mud mixture is by the gas-liquid separation zone of biogas-lift to the top.
Gas-liquid separation zone: the biogas in the mixture that is raised is in this and mud-water separation and derive treatment system, mud mixture then turns back to bottom mixing zone along return line, with the mud and the water inlet thorough mixing of reactor bottom, realized the internal recycling of mixed solution.
Anaerobic zone II: the waste water after anaerobic zone I handles, except that a part by the biogas-lift, remaining all enters anaerobic zone II by triphase separator.This district's sludge concentration is lower, and most of organism is degraded at anaerobic zone I in the waste water, so the biogas generation is less.Biogas imports gas-liquid separation zone by the biogas pipe, and very little to the disturbance of anaerobic zone II, this stop for mud provides favourable condition.
The settling region: the mud mixture of anaerobic zone II carries out solid-liquid separation in the settling region, supernatant liquor is drained by rising pipe, and sedimentary granule sludge returns anaerobic zone II Sludge Bed.
From HE-IC anaerobic reactor principle of work, as seen, realize SRT by 2 layers of triphase separator〉HRT, obtain high sludge concentration; Violent disturbance by a large amount of biogas and internal recycle fully contacts muddy water, obtains good mass transfer effect.
Working process:
Water inlet is through water distributor, input reactor, after mud that comes with the downtake circulation and water outlet are evenly mixed, enters in two anaerobic zones.There, most COD is degraded to biogas, and the biogas that produces at two anaerobic zones is collected by triphase separator and separated, and the generation gas lift.When gas is raised, driving water and mud moves upward, reach the gas-liquid separation zone that is positioned at the tank body top, here biogas separates from water and mud, and water and mud is mixed directly to be slipped to reactor bottom through concentric downcomer and to form internal recycling stream.By advanced treatment, remaining there biodegradable COD is removed in subordinate phase underload post processing zone in the water outlet of gas-liquid separation zone, and the biogas that produces at gas-liquid separation zone is admitted to degassing vessel, realizes that biogas separates and collection.Simultaneously, water outlet is left reactor gravity flow through effluent weir and is entered in the subsequent disposal.
The beneficial effects of the utility model: the structure of HE-IC anaerobic reactor and principle of work thereof have determined it having more advantage than other reactor aspect control anaerobic treatment influence factor.
(1) volumetric loading height: sludge concentration height in the HE-IC reactor, microbial biomass is big, and has internal recycle, and mass transfer effect is good, and the water inlet organic loading can surpass (the 15-25kgCODcr/m more than 3 times of common anaerobic reactor
3/ d).
(2) reduce investment outlay and floor space: HE-IC reactor volume rate of load condensate exceeds about 3 times of common UASB reactors, and its volume is equivalent to about 1/4～1/3 of common response device, greatly reduces the initial cost of reactor.And IC reactor aspect ratio very big (being generally 4～8), so floor space is economized especially, be fit to very much the industrial and mining enterprises of land used anxiety.
(3) capacity of resisting impact load is strong: (during COD=2000～3000mg/L), reactor internal recycle flow can reach 2～3 times of flooding quantity to handle low concentration wastewater; (during COD=10000～15000mg/L), the internal recycle flow can reach 10～20 times of flooding quantity to handle high-concentration waste water.A large amount of recirculated water and water inlet thorough mixing are fully diluted the objectionable impurities in the former water, greatly reduce the influence of poisonous substance to anaerobic digestion process.
(4) anti-low temperature ability is strong: temperature mainly is influence to digestion rate to the influence of anaerobic digestion.The IC reactor is owing to contain a large amount of microorganisms, and temperature becomes no longer significantly with serious to the influence of anaerobic digestion.Usually the anaerobic digestion of IC reactor can be carried out under normal temperature condition (20～25 ℃), has reduced the difficulty of digestion insulation like this, has saved energy.
(5) have the ability of buffer pH: the internal recycle flow is equivalent to the effluent recycling of the 1st anaerobic zone, and the basicity that can utilize COD to transform plays shock absorption to pH, makes that pH keeps optimum regime in the reactor, also can reduce the throwing alkali number of water inlet simultaneously.
(6) inner automated cycle, needn't additionaling power: the backflow of common anaerobic reactor realizes by external pressurized, and the IC reactor is realized the mixed solution internal recycle with the biogas that self produces as the power that promotes, and needn't establish the pump pump circulation, has saved power consumption.
(7) stable water outlet is good: utilize secondary UASB series connection classification anaerobic treatment, can compensate the high disadvantageous effect that produces of Ks in the anaerobic process.
(8) start-up period is short: sludge activity height in the HE-IC reactor, biological propagation is fast, provides favourable condition for reactor starts fast.The IC reactor start-up cycle is generally 1～2 month, and common UASB start-up period reaches 4～6 months.
(9) biogas utilization is worth high: the biogas purity height that reactor produces, and CH4 is 70%～80%, and CO2 is 20%～30%, and other organism is 1%～5%, can be used as fuel and is used.
