Detailed description of the invention
It should be understood that to those skilled in the art, content below is only of the present utility model exemplary
The description of embodiment, is not the restriction to this utility model widely protection domain, this utility model widely content
To be embodied by claims.
" sewage disposal system " mentioned by this utility model refers to, for making sewage reach a certain water body of draining or again
The process that it is purified by the water quality requirement used.In prior art, it includes but not limited to biomembrance process, activated sludge
Method, de-single dephosphorization process, A2O technique, oxidation ditch process, two-stage method technique, SBR technique and make on these Process ba-sis
Improvement or fusion.
Micro-nano bubble refers to diameter bubble between 50 μm to tens nanometer when bubble occurs, and this bubble is between micro-
Between rice bubble and nano bubble, there is the physical characteristic not available for conventional bubble.And the outstanding spy relevant to sludge treatment
Property includes:
1. self supercharging is dissolved
Bubble surrounding in water has a gas-liquid interface, and the existence of gas-liquid interface makes the bubble can be by the surface tension of water
Effect.For having the bubble of globular interface, the gas in capillary energy compression bubble, so that in more bubble
Gas is dissolved in water.According to Young-Laplace equation, Δ P=2 σ/r, the numerical value that Δ P representative pressure rises, σ represents surface
Tension force, r represents bubble radius.Diameter can be ignored the bubble pressure of more than 0.1mm is the least, and diameter 10 μm is small
Bubble can be by the pressure of 0.3 atmospheric pressure, and the bubble of diameter 1 μm can be by the pressure of up to 3 atmospheric pressure.Micro-nano bubble
Dissolving in water is a diminishing process of bubble, and the rising of pressure can increase the dissolution velocity of gas, along with than
The increase of surface area, it is increasingly faster that the speed that bubble reduces can become, thus is finally dissolved in water, and bubble will disappear in theory
The pressure missed the season is infinity.
2. the rate of climb is slow
According to Stokes' law, square being directly proportional of the rate of climb that gas ducks in drink and bubble diameter.Bubble diameter
The rate of climb of the least then bubble is the slowest.Knowable to the bobble rise velocity graph of a relation with bubble diameter, the gas of bubble diameter 1mm
The speed risen of ducking in drink is 6m/min, and the rate of climb that the gas of diameter 10 μm ducks in drink is 3mm/min, before the latter is
The 1/2000 of person.If it is considered that the increase of specific surface area, the solvability of micro-nano bubble increases by 200,000 times than general air.
3. gas solubility is high
Micro-nano bubble progressively dwindles into nanoscale in uphill process slowly, finally cuts down to bury in oblivion and dissolves in water, from
And the gas (air, oxygen, ozone, carbon dioxide etc.) dissolubility in water can be greatly improved.For common blister, gas
Dissolubility often affected by ambient pressure and restriction exists saturation solubility.Under standard environment, the dissolubility of gas is very
Difficulty reaches more than saturation solubility.And micro-nano bubble is owing to its internal pressure is higher than ambient pressure so that with atmospheric pressure be
Assuming that the gas supersaturation dissolution conditions that condition calculates is broken.
4. produce a large amount of free radicals
Microbubbles rupture moment, the acute variation disappeared due to gas-liquid interface, the high concentration ion that interface is gathered will be long-pending
The chemical energy stored discharges quickly, now can excite the substantial amounts of hydroxyl radical free radical of generation.Hydroxyl radical free radical has superelevation
Oxidation-reduction potential, is difficult to the pollutant such as benzene of oxidation Decomposition under normal condition in its superpower Oxidation degradable water produced
Phenol etc..Meanwhile,
5. mass-transfer efficiency improves
Ozone direct oxidation: O3+ pollutant → product
Ozone indirect oxidation: OH+ pollutant → product
In the prior art, the difficult problem that ozonation technology runs into derives from two aspects, on the one hand, because can be fast with ozone
The compound concentration of speed reaction is high, so mass transfer is the rate-limiting step of ozone oxidation；On the other hand, because water existing substantial amounts of
The inhibitor of ozone decomposed and the trapping agent of hydroxyl radical free radical, terminate and remove depollution with indirect reaction process for main path
The ozone oxidation reaction of thing so that those are difficult to can not be by the method for ozone indirect oxidation by the pollutant of ozone direct oxidation
Remove (when the concentration with ozone rapid-action compound constantly reduces, so that ozone oxidation reaction system becomes body at a slow speed
System, the most just belongs to this situation).
Research finds, has the compound (such as aromatic rings, unsaturated hydrocarbon etc.) of some particular functional group very
Easily and ozone reaction, some other compound (such as saturated hydrocarbon, alcohols, aldehydes etc.) and the more difficult reaction of ozone
(or reactivity is poor).Now, mass transfer step has just become the rate-limiting step of whole process, ozone distribution device to be to affect ozone
The principal element of oxidation rate.
Research shows, gas-liquid mass transfer speed and efficiency are inversely proportional to bubble diameter, and microbubble diameter is minimum, in mass transport process
Middle have clear superiority than traditional bubble.When bubble diameter is less, the surface tension at micro-nano bubble interface is to internal gas
Body creates compression so that microbubble constantly shrinks in uphill process and shows self pressurized effect so that more
Gas be dissolved in water through bubble interface.And along with the capillary action effect of the reduction of bubble diameter is more and more brighter
Aobvious, final internal pressure reaches certain ultimate value and causes bubble interface to rupture disappearance.Therefore, microbubble is in contraction process
Self supercharging performance this, can make mass-transfer efficiency at gas-liquid interface persistently be strengthened, and this characteristic makes microbubble i.e.
When making that gas content reaches supersaturated condition in water body, may continue to carry out the mass transport process of gas and keep efficient mass transfer
Efficiency.
This utility model is by utilizing the physicochemical properties of ozone, and the physical property of microbubble is simultaneously, further
Improve the mass-transfer efficiency of microbubble during sludge treatment, thus further utilize the oxidation activity of ozone.
Traditional handicraft or in the lab, the mode used by people is to be continually fed into ozone gas in sludge liquid.This
The mode of kind, ozone gas discharges the most from bottom to top, so that the utilization rate of ozone is the lowest, the ozone of about 80%
Gas is directly released in air after by liquid, causes the energy to waste greatly.In this utility model embodiment, to described
Mud adds Ca (OH)2Or NaOH, after pH value is adjusted to pH=9-11, by ozone with the form of micro-nano ozone bubbles from
Bottom release, evenly spreads in described mud.On the one hand, the form of micro-nano ozone bubbles, greatly increase ozone and liquid
Time of contact between body.On the other hand, by adjusting pH value, ozone can be further speeded up with the response speed of catalysis ozone
Consumption so that substantially there is no the abnormal smells from the patient of ozone processing scene.
Ozone discharges from bottom with the form of micro-nano ozone bubbles, greatly saves the usage amount of ozone, its compared to
Method of the prior art can realize lower energy resource consumption.
Total dissolved solidss (English: Total dissolved solids, abridge TDS), also known as dissolvability solid amount, survey
Amount unit is mg/litre (mg/L), and it shows in 1 liter of water dissolved with how many milligrams of soluble solids.TDS value is the highest, represents in water
The solute contained is the most.Total dissolved solidss refer to the total amount of whole solutes in water, including inorganic matter and the content of Organic substance.
Urban wastewater treatment firm is in sewage disposal process (sewage disposal system), and the mud of generation is typically to be mixed in water
Together, it is necessary to add flocculant postprecipitation, more just obtained the mud of moisture content about 80% by dehydration.It is appreciated that
, before adding flocculant, the mixture TDS of mud and sewage reaches dissolution equilibrium, and COD (COD) and TDS must
So there is certain relation, this is because sewage needs oxidized reducing substances be dissolved in water, i.e. the one of TDS
Part.A purpose of the present utility model is the decrement realizing mud, by by ozone with the form of micro-nano ozone bubbles from
Discharge bottom mud, evenly spread in mud.On the one hand, ozone resolves into through a series of chain reactions and has high reaction activity
Hydroxyl radical free radical, pollutant (unsaturated olefin, ammonia nitrogen, mercaptan, hydrogen sulfide etc.) are carried out non-selective oxidation degraded.Another
Aspect, mud, in rising rupture process, is broken up by micro-nano bubble.Specifically, the fibre composition in mud is interrupted, by dirt
In mud, soluble ingredient discharges.Without being limited by theory, it is also believed that, in ozone and the effect of microbubbles rupture energy
Under, the microbial cell in mud will be broken, and discharge moisture therein and Organic substance；Worm's ovum in mud can also be broken
Bad.Each reaction all will make the TDS in sewage increase further above.
And on the other hand, under the effect of micro-nano ozone bubbles, in sewage, the part of total dissolved solidss will necessarily be by oxygen
Change and decompose, with gas (NO2、N2、CO2Deng) release, so that TDS has declined, it is achieved the purpose of mud decrement.?
In embodiment of the present utility model, when reaction system declines at least 10%, it is believed that reaction terminates, and can stop adding in a subtle way
Nanometer ozone bubbles.
Along with industrial expansions such as oil, chemical industry, food and pharmacy, and the improving constantly of living standards of the people, city
In sanitary sewage and percolate, the content of ammonia nitrogen steeply rises.In recent years, along with expanding economy, more and more nitrogenous dirts
The arbitrarily discharge of dye thing causes harm greatly to environment.Nitrogen in waste water with organic nitrogen, ammoniacal nitrogen (NH4 +-N), nitre state
Nitrogen (NO3 --N) and nitrite nitrogen (NO2--N) etc. various ways exist, and ammoniacal nitrogen is one of topmost existence form.Dirty
Ammonia nitrogen in water refers to the nitrogen existed with free ammonia and ion ammonium form, is mainly derived from sanitary sewage or mud nitrogenous organic
The decomposition of thing.
Also, it is to be understood that, before adding flocculant, the mixture ammonia nitrogen value of mud and sewage reaches balance.And
After micro-nano ozone bubbles processes, NH4 +-N can change into NO3 --N, even N2.By enforcement of the present utility model
Example, finds to process through micro-nano ozone bubbles, and ammonia nitrogen value can be reduced to 80mg/L or following.
Sludge settling ratio (SV) refers to pour rapidly the Aeration tank active sludge intermixture of mixing in 1000ml graduated cylinder extremely
Full scale, after staticly settling 30 minutes, then precipitating sludge is sludge settling ratio (%) with the volume ratio of taken mixed liquor, also known as dirt
Mud settling volume (SV30) represents with mL/L.Because after sludge settling 30 minutes, typically can reach or close to maximal density, so
Universal using this time as the standard time of this index determining.
Sludge settling ratio is the reflection directly perceived that MLSS is quantitative.Formula: MLSS (g/L)=SV/SVI.SVI (ml/g) in formula
For sludge index, the i.e. cohesion of evaluation activated sludge, the index of sedimentation function.In stable waste water treatment process, due to SVI value
A certain stable region is substantially remained in, therefore, it is generally the case that in the case of SVI value is more stable within a period of time, dirty
Mud settling ratio (SV) and sludge concentration (MLSS) also exist certain linearly or logarithmically relation.I.e. sludge settling ratio can reflect
The concentration of mixed liquor in Aeration tank, it and sludge concentration direct proportionality.In stable sewage treatment process, due to SVI
Value substantially remains in a certain stable region within a period of time, therefore, it is generally the case that sludge settling ratio can reflect aeration
The concentration of mixed liquor in pond, it and sludge concentration direct proportionality.

Data analysis:
Table 1.pH value changes
The ozone concentration change that table 2. uses
Table 3.TDS value changes
The total values of nitrogen might of table 4. changes
Table 5.SV30 value changes
Table 6.MLSS value changes
Table 6 shows the change of MLSS in each test example, wherein, comparative example 1 and the (contrast of embodiment 13-15
Embodiment 2 and embodiment 16-18) as use condition, difference is not adjust pH value.It can be seen that do not adjusting pH
In the case of value, although the MLSS value of reaction system also has decline, but for adjusting the embodiment of pH value, contrast is implemented
The MLSS value of example reaction system declines the slowest.
Embodiment 1-3 is compared with embodiment 4-6, and in the case of the ozone amount used is identical, embodiment 1-3 uses micro-nano
After the formal layout of rice ozone bubbles, decompose the amount effect apparently higher than common ozone bubbles of MLSS.Further, from testing ground
Situation see, when using common ozone bubbles, embodiment 4-6, the testing ground of 10-12 and 16-18 are flooded with strong ozone
Abnormal smells from the patient, and the testing ground of embodiment 1-3,7-9 and 13-15 is entirely without the abnormal smells from the patient smelling ozone.This is from another angle more
Add proof, use micro-nano ozone bubbles can utilize ozone more efficiently.The ozone of same content, the form of micro-nano bubble
More mud can be processed, otherwise, the mud of same content, need the ozone of lower loading when using micro-nano bubble.Therefore,
Mud of the present invention realizes effective energy-saving effect.
On the other hand, embodiment 7-9 and 13-15 process 20 minutes in micro-nano ozone bubbles as can be seen from Table 6
After, MLSS decline more than 12%, after processing 40 minutes, MLSS decline more than 21%, after processing 60 minutes, MLSS decline 30% with
On.Above all it is believed that realize mud decrement to process (decrement more than 10%).
Table 5 shows the SV30 change of each embodiment.SV30 is the short-cut method analyzing sludge settling property.SV30 value
The least, sludge settling property is the best.SV30 value is the biggest, and settling property is the poorest.As can be seen from Table 5, pH value is not being adjusted
In the case of, although the SV30 value of comparative example 1 reaction system also has decline, but for adjusting the embodiment of pH value,
The amplitude declined is little.
Sludge settling property after embodiment 1-3,7-9 and 13-15 process substantially improves, and uses common ozone bubbles
Sludge settling property after embodiment 4-6,10-12 and 16-18, and comparative example 2 process is uneven.It is not bound by opinion
Limit, analyze the test using common ozone bubbles to process, it is believed that the reason that sludge settling property is deteriorated is ozone molecule
Aggregate in mud is broken up, but there is no oxidized consumption, therefore, during sedimentation again, need the longer time
Settle down completely.And using micro-nano ozone bubbles to process, micro-nano bubble itself can break up aggregate efficiently, the most micro-
Biological cell wall, and then make ozone and oxygen more effectively decompose oxidation organic composition therein, fundamentally reduce
The amount of mud.On the other hand, sludge settling property improves, and also implies that and reduces the flocculant that adds before sludge dewatering
Amount, the most fundamentally reduces the expense of Treatment of Sludge.
Table 4 shows the total nitrogen content change of each embodiment.From table 4, it can be seen that in the case of not adjusting pH value, though
So the total nitrogen content of comparative example 1 and 2 reaction system also has decline, but for adjusting the embodiment of pH value, declines
Amplitude little.Additionally, comparative example 1 compares with 2, comparative example 1 under the micro-nano ozone bubbles effect of 1 hour,
Total nitrogen drops to below 80mg/L, reviews the comparative example 2 using common ozone bubbles, and its total nitrogen content is still at 80mg/L
Above.Prove the efficient of micro-nano ozone bubbles again.
On the other hand, embodiment 4-6,10-12 and 16-18 are observed, when total nitrogen content is in higher level, such as embodiment 4-
6, elapse with the time of ozonization, total nitrogen content progressively declines；When total nitrogen content is at reduced levels, such as embodiment 7-12,
With ozonization time elapse total nitrogen content occur fluctuation, time and rise, time and decline.Without being limited by theory, we recognize
For, when total nitrogen content is less than 80mg/L, the minimizing degree of mud has been enter into plateau, and sludge reduction is basically completed.
Table 3 shows the TDS change of each embodiment.From table 4, it can be seen that in the case of not adjusting pH value, although right
Also there is decline than the TDS of embodiment 1 and 2 reaction system, but for adjusting the embodiment of pH value, the amplitude of decline is not
Greatly.
Calculated by simple, it can be seen that embodiment 7-9 is after micro-nano ozone bubbles effect 20 minutes, and TDS is already
Have dropped more than 10%；After acting on 60 minutes, TDS declines 25-34%.In all of the embodiments illustrated, effect is best.And work as
When improving the concentration of micro-nano ozone at identical conditions, i.e. embodiment 13-15, the amplitude that TDS declines is on the contrary than embodiment
7-9 is little.It is believed that this is because reaction system can accommodate gas concentration time limited, when the micro-nano gas of ozone
During bubble excess, the reduction to TDS the most mutually suppresses so that it is the effect to the common ozone bubbles using low concentration is similar
(i.e. embodiment 10-12).
Table 2 shows that the ozone concentration that each embodiment uses, table 1 show that the pH value before and after the reaction of each embodiment changes.
According to the result of embodiment, under the micro-nano ozone bubbles effect of 1 hour, pH value can be reduced to 7.0.It is believed that now
Sludge reduction process is complete.
Without departing under spirit and scope of the present utility model, those skilled in the art can true of the present utility model these
With other deformation or replacement.It will additionally be understood that the various aspects of embodiment can fire part mutually be replaced on the whole.And this
Skilled person should be understood that and is specifically described this utility model the most by way of example.
