Below respectively each district is introduced.
Cloth pool: cloth pool is comprised of water distribution system 9, return line 10, water inlet pipe 15, time mud water inlet pipe 16, the strengthening water inlet of cloth pool is redistributed with time mud, guarantee in water inlet, backflow mixed liquor and reactor that mud fully mixes, uniform stirring, guarantee reaction effect.

Working process of the present utility model is: water inlet enters reaction chamber I by bottom and mixes with granule sludge, most of organism is degraded at this, produce a large amount of biogas, biogas is collected by lower floor's triphase separator, a large amount of biogas is carried mixed solution secretly and is entered top layer air water separator by upcast, at this most of biogas, departing from mixed solution arranges outward, it is large that the density of mixed stream becomes, under action of gravity, by return line, get back to the bottom of reaction chamber I, mix with waste water, the granule sludge of reaction chamber I, thereby realized the circulation of fluid at inside reactor.Internal recycle increases the liquid phase upflow velocity of reaction chamber I greatly, adds water distributor eddy flow and impact, and a large amount of gas and ascending current acting in conjunction fully mix gas, solid, liquid three-phase in reactor; The liquid phase upflow velocity of reaction chamber II is less than reaction chamber I, this region is except proceeding biological respinse, due to the reduction of upflow velocity, also serve as the breeze way between reaction chamber I and settling region, to solve running mud, guarantee to precipitate rear effluent quality and play an important role.
The utlity model has following advantage.
1.the utility model water inlet pH wide accommodation, saves and adds alkali number, for enterprise reduces working cost.
If adopt common anaerobic reactor, need add alkali is adjusted to water inlet pH value between 6.5-7.5, and the utlity model has powerful internal recycling system, pH is played to shock absorption, make the pH in reactor keep stable, water inlet need not regulate pH to meet the demands, therefore for other traditional IC and UASB, EGSB anaerobic reactor, can reduce the throwing alkali number of water inlet, thereby save dosing, reduce working cost.
2.water distribution is even, without stopping up.
The stirring action of water inlet distributor is a huge energy derive in anaerobic reactor, when but the upflow velocity producing when the stirring action of water distributor does not reach certain speed, the biogas producing in reactor is easily accumulated in granule sludge layer, gas production rate is inhomogeneous, cause internal recycle unstable, form certain vicious cycle.
The water distribution system that the utility model adopts is through strict design calculation, and in conjunction with similar waste water actual treatment experience, original point type water distribution is transformed into existing whirlwind-type water distribution manner, guarantee to be uniformly distributed at reactor bottom into the mixed solution of water and backflow on the one hand, assurance reactor is efficient, steady running, on the other hand, granule sludge is better mixed with waste water energy, make the higher upflow velocity of maintenance in anaerobic reactor, higher upflow velocity discharges the methane energy producing in anaerobic sludge rapidly, in granule sludge, do not stop, metastable running environment can be grown mud rapidly and uniformly, guarantee the outlet effect of anaerobic reactor.
3.shock-resistant loadby force.
Because the utility model is provided with internal circulation system, the ability of internal circulation system is mainly provided by the biogas producing in reactor, and when COD load increases, the generation of biogas increases thereupon, and the air lift of internal recycle increases thus.When processing high-concentration waste water, the flow of internal recycle can reach 10~20 times of flooding velocity, and Coal Gas Washing Cycling Water and objectionable impurities are fully diluted, and greatly reduces harmful degree, thereby has improved the anti impulsion load ability of reactor; When COD load is lower, biogas output is also low, thereby forms lower internal recycle flow.Therefore, internal recycle is actual has played the effect of self-poise COD impact load for reactor.
And only rely on outer circulation or not possess the EGSB of the recycle system and UASB reactor to very poor of the load variations adaptability of waste water, easily cause the disintegration of mud, cause and run mud phenomenon, and most factory effluent all has the feature of production instantaneity, in the short period of time, change of water quality is very large for waste water, if there is no the good recycle system, can cause anaerobic reactor operation very poor, have a strong impact on effluent quality.
4.toxicity suppresses tolerancepower.
Bacterial classification in general anaerobic reactor adopts, and to be that mud bacterial classification is inner form singlely, and bacterial classification quantity and flora bacterial classification are less, very simple of structure, so the growth that the lower toxicity of waste water can anti-bacteria is even lethal by bacterial classification.Granule sludge bacterial classification of the present utility model is different, is necessarily to count by counting, so that the complicated ecosystem that forms of more than one hundred million different floras, thereby the waste water that can adapt to different water quality conditions and contain toxicant.
5.debugging timeshort.
The utility model initial start-up initial failure period is about 10~15 days, the restarting time is about 7~10 days, and the first initial failure period of UASB and EGSB is respectively 60~180 days and 50 days, the restarting time is respectively 30~60 days and 30 days, and longer initial failure period makes within the production cycle most of the time waste water can not qualified discharge severe contamination surrounding enviroment.
The utility model completes in equipment, pipelining, possesses after debugging condition, within 15 days, can make water outlet reach design loading, and effluent quality reaches design water quality requirement, COD crclearance reaches more than 90%.
6.bacterial classification is more mature and stable.
The stability of anaerobic technique and high efficiency depend on that generation has the mud of good settling property and high methane activity to a great extent, especially particulate state mud, the granule sludge fast growth producing in the utility model, mud even particle size distribution, activity is higher, and the adaptive temperature of granule sludge is at 30-37 ℃, subject range is wider, and impact resistance is stronger.
The utility model adopts two-layer triphase separator, mud, water, gas can better be separated, and granule sludge is trapped in reactor, prevent that system for anaerobic treatment from running the generation of mud phenomenon, guarantee longer solid retention time, make reactor efficiently operation under higher biological concentration state.
And bacterial classification mud in domestic traditional anaerobic reactor exists mainly with loose flocculence body, adaptability is poor, and mud easily disintegrates, and easily occurs that mud floating runs off, and makes traditional anaerobic reactor can not steady running under higher load.
7. operationsituation is better, and effluent quality is more stable.
Fluidised form in general anaerobic reactor is quite complicated, fluidised form in reaction zone and gas production rate and reaction zone height correlation, in general, in the sludge blanket of bottom, reaction zone, result due to aerogenesis, the tolerance that part section passes through is more, forms the air-flow of one rising, drives part mixed solution (referring to mud and water) to move upward.Meanwhile, this strand of gas, current medium around move downward, and cause backmixing, and this fluidised form causes the short stream of water.In the place away from this strand of rising gas, current, easily form dead angle.Intrasystem this dead angle and short stream mode make waste water can not obtain processing fully thoroughly, and effluent quality is unstable.The utility model arranges external circulating system, upper strata muddy water mixed solution can be back to water distribution system, the reliability of enhancing reactor.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
