Elaborate a lot of details in the following description in order to fully understand the present invention, but, the present invention also may be used
To be implemented different from other modes described here using other, therefore, protection scope of the present invention is not described below
Specific embodiment restriction.
The present invention adopts up-flow anaerobic sludge blanket (UASB, upflow anaerobic sludge blanket) to react
Device processing kitchen garbage, waste-water, effective fermented organic, kitchen garbage, waste-water enters reactor, reactor bottom from bottom to top
There are high concentration, highly active Sludge Bed, in waste water, most of Organic substance here is degraded to methane and titanium dioxide through anaerobic fermentation
Carbon, gas is discharged from top, and the liquid after process is also discharged from top.
As shown in figure 8, first aspect present invention provides a kind of kitchen garbage, waste-water processing method, comprise the steps：
S101 injects described kitchen garbage, waste-water in first order upflow anaerobic sludge blanket reactor and is reacted, and maintains
Temperature, between 50～55 degrees Celsius, such as can maintain temperature on 50,51,52,53,54,55 degrees Celsius, or any of the above-described
Between between two temperature, produce the first biogas slurry.Described first order upflow anaerobic sludge blanket reactor hydraulic detention time is
30d (30 days).Every 24 hours to the described first order upflow anaerobic sludge blanket reactor charging and discharging once.
S102 described first biogas slurry is injected in the upflow anaerobic sludge blanket reactor of the second level and is reacted, and remains anti-
Answer temperature between 50～55 degrees Celsius, such as temperature can be maintained on 50,51,52,53,54,55 degrees Celsius, or arbitrarily on
Between stating between two temperature, the hydraulic detention time that arranges described second level upflow anaerobic sludge blanket reactor is 10～
20d.Test result indicate that second level UASB reactor COD (chemical oxygen demand, COD, represent with
Chemical method measures the amount needing oxidized reducing substanceses in water sample) clearance reaches 15.5%-65% so that total COD goes
Except rate brings up to 91%-95% by the 85% about of one-level UASB；First order UASB daily output tolerance is 81.5L/d-330.0L/d,
The daily output tolerance of second level UASB is 35.8L/d-102.7L/d.Therefore, two-stage tandem UASB reactor more fully digests
Organic substance in kitchen garbage, waste-water, can reduce for subsequent treatment and process load.During the second stage reactor HRT=20d, COD goes
Except rate highest, treatment effect is best；During HRT=15d, produce tolerance highest daily.
The embodiment of the present invention adopts two-stage series connection UASB reactor, and reactor rolls two-layer using steel plate and is welded, single
Total effective volume 200L of individual device, high × upper diameter × lower diameter：1950mm × 600mm × 300mm, the high 1500mm of cylinder, outward
Bag 3cm insulation material, device divides into thermostat water bath, and reactor opens up 4 equidistant sample taps.There are feed pipe, outlet pipe, aerofluxuss
Pipe, water-bath overflow pipe and water-bath blow-down pipe.Two identicals are normal start after middle moderate temperature UASB reactor, using semicontinuous
Formula feeding manner, feeds with discharging once for every 24 hours.Test is extracted enough first from changing food waste process for producing line
Waste water, is maintained the temperature at 35 DEG C about, is squeezed in first order UASB reactor by peristaltic pump and carry out coagulation, this order reaction
Device remains that hydraulic detention time (HRT) is that 30d is constant, and temperature control is in (52 ± 2) DEG C.By the above-mentioned first order after process
The reacted outlet water biogas liquid of UASB, as the charging of second level UASB, is passed through second level UASB reactor and is reacted, and temperature is same
Sample controls in (52 ± 2) DEG C, i.e. series connection becomes two grades of UASB handling process.Pass through again to change second level UASB reactor
HRT (respectively 20d, 15d, 10d), research treatment effect to kitchen garbage, waste-water through two-stage tandem UASB anaerobic digestion,
And the difference impact to second level UASB anaerobic digestion for the HRT.
Tested according to the method for the present invention, result is as follows.
In being reacted by Fig. 1, Fig. 2 secondary anaerobic, COD concentration and COD clearance change curve can be seen that first order UASB
Reactor inlet COD concentration is 70000mg/l～80000mg/l, controls HRT=30d, after reaction, water outlet COD is basically stable at
8000mg/l～12000mg/l, COD clearance does not have larger fluctuation, and more stable maintains 86% about.Immediately
Reacted for first order water outlet is passed directly in the UASB reactor of the second level, as second level UASB reactor HRT=20d,
Effluent COD concentration substantially remains between 3600mg/l～40000mg/l, and COD clearance is also more stable, it is maintained at 57%～
So that secondary response total COD clearance reaches 94%～96% between 65%.Maintaining first order UASB reactor HRT=30d not
In the case of change, increase second level UASB reactor feed amount so that during HRT=15d, second level UASB water outlet COD was at first 4 days
Increased, up to 6065mg/l, decrease afterwards and gradually tend towards stability, be maintained at 4200mg/l, COD removes
Rise after the fall that takes the lead in and finally stable 57% about, total COD clearance is stably 94% about.Continue to increase inlet amount and make the
Two grades of UASB reactor HRT=10d, system water outlet COD and the fluctuation of COD clearance are larger, and water outlet COD falls after rising, the 5th
It is increased to 10450mg/l, has declined afterwards, finally stablize in 6500mg/l about, COD rises, the 5th after removing the fall that takes the lead in
It falls below minimum 15.52%, has risen and stablized 38% about afterwards, compared with decline during HRT=20d and HRT=15d
Larger, total COD clearance is finally stablized 91% about.The reason this problem is probably the stop of the second stage reactor
Time is too short, result in residual organic substances and remains insufficiently digested degraded and stop in the reactor, causes effluent COD concentration
Increase.If not taking certain measure to be processed it is likely that a large amount of accumulation of organic acid in reactor can be led to, destroy
The internal balance environment of system.
In being reacted by Fig. 3 secondary anaerobic, the change curve of gas production can be seen that B grade anaerobic fermentation first order reaction and produces
What tolerance was more stable is maintained at 281.5L/d～330.0L/d, and the amplitude changing is little.But with kitchen rubbish high temperature
UASB anaerobic fermentation is compared, and gas production is less, and factor of created gase is relatively low.And after second level UASB reactor is using anaerobic digestion gas production
Biogas slurry carry out anaerobic digestion gas production reaction again, still can obtain higher gas production.When secondary response HRT=20d, produce
Tolerance is basically stable at 55.3L/d～77.0L/d；After minimizing HRT makes HRT=15d, gas production occurs in that small size increase, reaches
To 64.6L/d～102.7L/d.When continuing to reduce HRT to 10d, gas production presents and first reduces the trend increasing afterwards and generally
Compare and be declined slightly during HRT=15d, be reduced to 35.8L/d always from 92.8L/d within first 6 days of reaction, from the 7th day start by
Gradually go up and finally stablize in 73.0L/d about.Its reason is probably that inlet amount is excessive, the volatility producing after Organic substance acidifying
Organic acid cannot sufficiently convert and accumulate in systems, change methanogen and utilize organic acid synthesizing methane gas
Suitable environment, inhibits the activity of methanogen to a certain extent, decreases gas production.Generally speaking, through first order UASB
Kitchen garbage, waste-water after reactor anaerobic reaction still has higher gas production utilization rate, is processed by two-stage tandem UASB
Kitchen garbage, waste-water, sufficiently can utilize Organic substance therein, obtain more biogas.
By Fig. 4 and, VFA (volatile fatty acid), the change of basicity and VFA/ basicity and pH in the reaction of Fig. 5 secondary anaerobic
It is more stable that the change curve of (hydrogen ionexponent) value can be seen that first order UASB reactor water outlet VFA, basic keeps
In 2400mg/l～2900mg/l, basicity substantially remains in 8500mg/l～9500mg/l, and the ratio of VFA/ basicity is maintained at
0.29 about.After second level UASB reaction, water outlet VFA is relatively stable in HRT=20d and HRT=15d, is maintained at
2200mg/l～2700mg/l about, basicity is also stably maintained at 8400mg/l～8900mg/l, the ratio of VFA/ basicity relatively
Value is maintained at 0.26～0.31；And in HRT=10d, the water outlet VFA of second level UASB increases to 2700mg/l～3500mg/
L, reaches peak 3502.76mg/l on the 4th day, basicity but drops to 7000mg/l～8300mg/l, and VFA/ basicity now increases
To 0.33～0.45.This is excessive mainly due to inlet amount, caused by the organic acid producing after Organic substance acidifying gradually accumulates, such as
Fruit long reaction goes down it is more likely that the accumulation of VFA can be led to excessively, and the acid-base balance environment in destruction system is finally led
Cause reactor that acidification phenomenon occurs, react unsuccessfully.
As shown in Figure 5 although the charging pH value of first order reactor is relatively low, between 3.75～4.15, but
First order UASA water outlet pH value has reached 7.52～7.85, and this scope is in the field of activity of methanogen, its main cause
It is probably containing enough basicity, the VFA producing in energy neutralization reaction in reactor, effectively prevent the decline of pH value.Through
After the UASB reactor of the second level, water outlet pH value range is also maintained at 7.52～7.85, and does not have to occur bright because of the change of HRT
Aobvious change.This is mainly relevant with the value of VFA/ basicity.Although in HRT=10d, VFA increased for second level UASB water outlet,
Basicity has reduced, but the ratio of VFA/ basicity, still between 0.33～0.45, illustrates that reactor still has enough delaying
Rush ability, so the pH value in this stage does not substantially reduce.
In being reacted by Fig. 6 secondary anaerobic, the change of ammonia nitrogen can be seen that in first order anaerobic reactor influent ammonium concentration
700mg/L about in the case of, first order water outlet ammonia nitrogen is up to 2300mg/L, and this is anti-with kitchen rubbish high temperature anaerobic digestion
Should after water outlet ammonia nitrogen concentration 1700.0mg/L about compare and increased.Its reason is probably that mesophilic bacteria utilizes protein, ammonia
During the degraded of the itrogenous organic substances such as base acid, the ammonia nitrogen ability that produces does not have high temperature bacterium strong, thus lead to ammonia nitrogen content bigger.And warp
After crossing second level UASB reactor reaction, the concentration of water outlet ammonia nitrogen does not have the too big change of generation, not with HRT's yet
Change and too big change occurs, substantially suitable with the water outlet ammonia nitrogen of first order UASB reactor.This explanation is through the second level
After UASB reactor reaction, ammonia-nitrogen content is not effectively removed, and changes HRT pair of second level UASB reactor
The change impact of water outlet ammonia nitrogen is inconspicuous.
In being reacted by Fig. 7 secondary anaerobic, the change of TS (total solid) can be seen that in secondary anaerobic system TS mainly the
Remove in one-level anaerobism, TS has been reduced to averagely by average 45.4g/l when intaking after first order UASB reactor reaction
19.3g/l, clearance reached 57.5%.And the TS after the UASB reactor reaction of the second level is by average again
19.3g/l drops to 15.7g/l, and clearance only has 18.7% about, and changes the HRT of second level UASB reactor to going out
The change impact of water TS is inconspicuous.The removal of changing food waste anaerobic reaction TS mainly in the first order reaction, the second order reaction pair
The removal effect of TS is inconspicuous, and this is primarily due to degradable large particulate matter in changing food waste and is easy under anaerobic
It is degraded, and the large particulate matter of difficult degradation is also difficult to degrade even across second level anaerobic reaction.
Result shows that second level UASB reactor COD clearance reaches 15.5%-65% so that total COD clearance is by one-level
The 85% about of UASB brings up to 91%-95%；First order UASB daily output tolerance is 81.5L/d-330.0L/d, second level UASB
Daily output tolerance be 35.8L/d-102.7L/d.Therefore, two-stage tandem UASB reactor has more fully digested changing food waste and has given up
Organic substance in water, can reduce for subsequent treatment and process load.During the second stage reactor HRT=20d, COD clearance highest, place
Reason effect is best；During HRT=15d, produce tolerance highest daily.
