Description
Technical field
The present invention relates to the improvement of the agglutinant of dirty water of purifying treatment or polluted water, for example, toward industrial waste handle drop into agglutinant in dirty water that the place takes place or the polluted water after, the fouling product or the pollutent that contain in aggegation dirt water or the polluted water purify water.Particularly make it form solid floating matters (block) such as fouling product at short notice, make it the sedimentary while, make heavy metal class in the processed water and halogen, metalloid dvielement no longer stripping to moisture.
Background technology
Generally, be divided into organic agglutinant and inorganic agglutinant by the agglutinant that purifies water that becomes the solid floating matter to carry out to the fouling product aggegation in the processed waters such as dirty water or polluted water.Wherein, organic agglutinant is to be host (referring to patent documentation 1) with the organic polymer, because of leaving over down a large amount of organism in the processed water after handling, if the discharging of the draining after the processing is easy to form new pollution by oxidation.If the problem that also exists is exactly the draining that discharging contains large amount of organic simultaneously, natural microbial environment can be damaged, and also can become serious obstruction is decomposed this natural cleaning action of removing mud by microorganism reason.
In addition, organic agglutinant when handling dirty water or polluted water, in order significantly to change the pH value in these processed waters, aspect treatment process, just must be provided with by medicine in the neutralizing well of pH value.Therefore the problem that exists is when needing more treatment time along with increasing the purifying treatment operation, particularly will make pH value reach the middle considerable time of sexual needs by adding medicine.Also having a problem in addition is exactly could discharge after draining after the purifying treatment must fully be placed in neutralizing well, so just can not successive discharge processing processed water.
Moreover, because use the moisture after organic agglutinant purifies, the viscosity of solid floating matter that the tendency that uprises is all arranged, moisture is difficult for taking off dried, even if later on by various dehydration procedures, the solid floating matter fully can not be dewatered and subtract appearance, to such an extent as to there is the problem of the solid sludge quantity that finally can not reduce recovery.
On the other hand, inorganic agglutinant mainly is the cohesive force (referring to patent documentation 2) that utilizes the carbonium of aluminum ion or iron ion, compares the tendency that has a little less than the cohesive force with organic agglutinant.Therefore, in the various dehydration procedures of back, it is destroyed to have the solid floating matter, sneaks into the problem of the suspended matter of corpusculed in the water after the processing.In addition, inorganic agglutinant is usually owing to reduce the pH value of processed water, still exist because of the problem of a large amount of time that neutralizing well need spend be set the same with organic agglutinant.
Particularly no matter be organic or inorganic, though agglutinant has in the past improved cohesive force, but because the solid floating matter that produces by aggegation can not separate fully with moisture, in the dehydration engineering afterwards, after must concentrating engineering through mud, dehydration is finally reclaimed dirty composition as dewatered solid mud once more.That is to say, must use costliness and complicated dewatering system, need expensive and cost in the time of a large amount of time, processed also needs the time.
And, agglutinant in the past is no matter be organic or inorganic, agglutinant self can not be removed oil content, mercury, cadmium, lead, sexavalent chrome fully, heavy metal classes such as arsenic, the fluorine of halogen element, between metal and nonmetal between the boron etc. of metalloid of neutral element, just must be in order to remove these oil contents, heavy metal class by various medicaments, treatment process by means of other.

[effect of invention]
The present invention because use inorganic natural mineral such as Tai-Ace S 150, calcium sulfate, yellow soda ash to be main raw material, can not leave over organism in the waste water after therefore handling as mentioned above, can the destroy microorganisms environment even be discharged into nature yet, realized environment protection.Stand facing each other mutually with the current potential of Tai-Ace S 150 because of the significantly potential difference that calcium sulfate and yellow soda ash are arranged simultaneously, by by alkali, acid or have the be separated by condensation effect that produces of conflicting each other of material of current potential very far away of numerical value and form firm cohesive force, can effectively aggegations such as fouling product be got up.In addition, just can effectively handle processed waters such as dirty water, the actual benefit that can reduce cost is arranged because only need drop into a spot of agglutinant.
The present invention as mentioned above, because added the cause of pH regulator agent such as cement, the pH value of the processed water that reduces because of Tai-Ace S 150 can neutralize mainly, in front and back with the agglutinant purifying treatment, need not in other neutralizing well with medicament and carry out neutralizing treatment, not only cut down cost and engineering and can carry out simple operation, also saved in and the storage period of processed water in neutralizing well, the actual benefit that can handle dirty water or polluted water continuously and effectively purify is arranged.
The present invention as mentioned above, because added cement, cement can be strengthened the solid floating matter itself that produces because of aggegation, therefore after dehydration procedure in the solid floating matter can not be damaged and once again be blended into moisture, when improving aggegation efficient, cement constitutes the core of solid floating matter, accelerates the sinking velocity of the solid floating matter that the high specific gravity by cement self causes, and then the solid floating matter is separated fully with moisture.Therefore need not to concentrate engineering by mud in addition again and just can dewater the actual benefit that has treatment project of making or treatment facility significantly to oversimplify fully.
The present invention as mentioned above, because mixed magnetic materials such as ferrite, when carrying out aggegation by the crosslinked action of aluminium polyvalent ion, the countless magnetic powder of drawing over to one's side in the solid floating matter after the crosslinked action involves mutually by faint magnetic force (the faint magnetic force of ferrite powder self), when can form bigger solid floating matter, because the high specific gravity that magnetic materials such as ferrite are had can improve the proportion of solid floating matter integral body significantly, therefore need not also can accelerate the sinking velocity of the solid floating matter after the aggegation, further promoted separating of solid floating matter and moisture by the attraction of magnetic force.
And, the present invention as mentioned above, because use inorganic natural mineral as main raw material, different with organic agglutinant, can not improve the viscosity of solid floating matter, the very low solid floating matter of good water ratio that can obtain dewatering only needs simple processing just mud fully can be subtracted appearance when significantly shortening dewatering time, particularly sinking to mutually combining with above-mentioned quickening to obtain very high dehydrating effect.
In addition, the present invention as mentioned above, because further sneaked into by iron, Sulfothiorine, chitin, the chelating promotor that the powder of citric acid constitutes, chitin and iron powder absorption oil content by oil content contained in the processed water or metallic element there being very high adsorptive power or make metallic element and citric acid reacts and adsorbs, because of Sulfothiorine can promote detoxification, removing oil content, the heavy metal dvielement, the part halogen, in the time of the metalloid dvielement, metallic element that becomes oxide compound etc. further becomes basic oxide again, have ionic stronger covalent linkage and settle out, because covered these elements, these elements are stripping once more not, therefore the oil content that the agglutinant before can not be handled, heavy metal, the fluorine of halogen element, or the boron of metalloid element etc., only need aggegation to handle now and just can remove.
Embodiment
Below describe embodiment of the present invention in detail.The present invention is the agglutinant that is used for dirty water of purifying treatment or polluted water, and pH regulator agent in the host that is made of Tai-Ace S 150, calcium sulfate, yellow soda ash, proportion dose, chelating promotor are made after mixing.
The host that is made of Tai-Ace S 150, calcium sulfate, yellow soda ash is the fouling product in the aggegation processed water is removed fouling product then from processed water center composition; because be inorganic natural mineral; can not leave over organism in the waste water after the processing, waste water is released to nature can the destroy microorganisms environment yet, be suitable for realizing environment protection most.
In addition, different with organic agglutinant, because can not improve the viscosity of the solid floating matter after the processing, can obtain the lower solid floating matter of water ratio, therefore significantly shorten dewatering time, simultaneously, only needed simple processing just mud fully can be subtracted appearance.
This occasion, it is because there is the significantly potential difference of calcium sulfate and yellow soda ash relative with the current potential of Tai-Ace S 150 that Tai-Ace S 150, calcium sulfate, yellow soda ash are used as host, by by alkali, acid or have the numerical value condensation effect that the very far material conflict each other of current potential produces of being separated by and can form firm cohesive force.Therefore, this more weak weakness of cohesive force of inorganic agglutinant before also having overcome in the very high feature of environmental protection that inorganic agglutinant had before keeping, like this, in effective aggegation fouling product, only need to drop into a spot of agglutinant and just can effectively handle processed waters such as dirty water, and then reduce cost.
The pH regulator agent is that be used for neutralizing Tai-Ace S 150 because of the host composition has the pH value of the processed water that reduces tendency, and concrete can use cement.This occasion, though the original pH value of pH regulator agent in can left and right sides processed water is to adjust its composition or the shared ratios (with respect to the weight ratio of agglutinant integral body) of composition with the pH value stabilization of processed water at the neutral region 4.0～9.0 that nature is not being had influence.
By this pH regulator agent, when handling, aggegation the pH value of processed water can be adjusted to neutral region, therefore using agglutinant to carry out the front and back of purifying treatment, need not to make with medicament carry out neutralizing treatment by other neutralizing well, not only cut down cost and operation and can carry out simple operation, and needn't processed water be detained for a long time in order to neutralize, can handle dirty water or polluted water and effectively purification continuously.That is to say, when the present invention is a kind of very high feature of environmental protection that not only can keep that former inorganic agglutinant has but also the pH value of the agglutinant (no matter being inorganic agglutinant or organic agglutinant) before having solved change the agglutinant of the weakness of (reduction).
In addition, use the occasion of cement as the pH regulator agent, cement can be strengthened the solid floating matter that produces because of aggegation, therefore after the dehydration engineering in can not be damaged once again the moisture of sneaking into of solid floating matter, when improving aggegation efficient, cement constitutes the core of solid floating matter, accelerates the sinking velocity of the solid floating matter that the high specific gravity by cement self causes, and then the solid floating matter is separated fully with moisture.That is to say, cement not only has the effect of the pH regulator agent (neutralizing agent) of the pH value decline that prevents processed water, also have the effect of proportion dose as described below, the dual function of reinforcement because of aggegation solid floating matter that produces and the sinking velocity of accelerating the solid floating matter promptly arranged simultaneously.
The proportion dose can promote to become thick because of the solid floating matter that aggegation produces, and accelerates the sinking velocity of solid floating matter, promotes separating of moisture and solid floating matter, specifically uses magnetic materials such as ferrite.Ferrite is when carrying out aggegation by the crosslinked action of aluminium polyvalent ion, the countless magnetic powder of drawing over to one's side in the solid floating matter after the crosslinked action involves mutually by faint magnetic force (the faint magnetic force of ferrite powder self), when can form bigger solid floating matter, because the high specific gravity (exceeding the solid floating matter) that magnetic materials such as ferrite are had can significantly improve the proportion of solid floating matter integral body, therefore need not also can significantly accelerate the sinking velocity of the solid floating matter after the aggegation, further promoted separating of solid floating matter and moisture by the attraction of magnetic force.
Because by proportion dose separate solid floating matter and moisture fully, the back need not to concentrate engineering by other mud again and just can dewater fully, the mud that is carried out after aggegation concentrated and dehydration procedure in the past, only need dehydration procedure just can guarantee volume reduction rate now, significantly simplified treatment process and treatment facility.
In addition,, be not limited in ferrite,, also can use other magneticsubstance as long as can bring into play same cohesion if make the proportion dose with magneticsubstance.In addition, cement as described above both can also can use as the proportion dose with magneticsubstance separately as the proportion dose.
It is to be made of iron, Sulfothiorine, chitin, citric acid that huge legendary turtle is closed promotor, can remove oil content and metallic element and close reaction by huge legendary turtle, prevent these compositions once more stripping can remove the composition in these processed waters that former agglutinant can not remove to moisture.
Specifically, this chelating promotor by oil content contained in the processed water or metallic element there being very high adsorptive power chitin and iron powder absorption oil content or make metallic element and citric acid reacts and adsorbs, promote detoxification by Sulfothiorine, removing oil content, the heavy metal dvielement, the part halogen, in the time of the metalloid dvielement, metallic element that becomes oxide compound etc. further becomes basic oxide again, settle out with ionic stronger covalent linkage, because covered these elements, these elements are stripping once more not, therefore the oil content that the agglutinant before can not be handled, heavy metal, the fluorine of halogen element, the boron of metalloid element etc. only need aggegation to handle now and just can remove.
In sum, agglutinant of the present invention is to add cement flour, ferrite powder in the host that is made of Tai-Ace S 150, calcium sulfate, yellow soda ash and closed by the huge legendary turtle that iron, Sulfothiorine, chitin, citric acid powder constitute to make after promotor is mixed, and this is the optimal morphology that carries out an invention.
Next, the preferred proportion of these compositions once is described, the Tai-Ace S 150 of 20～50 weight parts is (with respect to the weight part of agglutinant integral body, among the present invention everywhere all with), the host made after mixing of the calcium sulfate of 10～40 weight parts, 5～20 weight parts of sodium carbonate, to the magnetic material powders such as ferrite powder of the cement flour that wherein adds 5～20 weight parts, 5～10 weight parts, the iron powder of 5～20 weight parts, the Sulfothiorine of 5～20 weight parts, the chitin of 1～10 weight part, the citric acid of 5～20 weight parts, make after the mixing.
This occasion, particularly, why account for above-mentioned allotment ratio about playing the center composition Tai-Ace S 150 of agglutination, if be because the verified amount of Tai-Ace S 150 of getting below 20 weight parts, cohesive force can reduce, and can make the processed water gonorrhoea that becomes and get words more than 50 weight parts.
For the effect of suitable above-mentioned each composition of performance, wish the uniform dispersing and mixing of above-mentioned each composition.In addition when actual fabrication,, also can mix the back to all compositions simultaneously and generate though after can earlier Tai-Ace S 150, calcium sulfate, yellow soda ash being generated host, add cement flour, ferrite powder, huge legendary turtle again and close the agglutinant that promotor is mixed the after-cost invention.
The following describes several embodiment for the function of confirming the various compositions that the present invention is contained.Specifically be set at 4 kinds of agglutinants, these 4 kinds of agglutinants are got the silt solution (processed water) that 20ppm adds 1 liter of 1000ppm to respectively after, confirmed the agglutination of solid floating matter.Embodiments of the invention have been set respectively and in order to confirm the comparative example of agglutinant effect at these agglutinants.It specifically is the agglutinant (A agent) of having set comparative example 1 by the independent generation of Tai-Ace S 150, agglutinant (the B agent: host promptly of the present invention) by Tai-Ace S 150, calcium sulfate, yellow soda ash mixing back generation of comparative example 2, embodiments of the invention 1 add the agglutinant (C agent) that cement flour generates with above-mentioned B agent (host of the present invention) lining, the agglutinant (D agent) that embodiments of the invention 2 generate the ferrite powder that adds magneticsubstance in the above-mentioned C agent
This occasion, the D agent of embodiment 2 are to generate after the uniform dispersing and mixing of ferrite powder by the cement flour of the calcium sulfate of the Tai-Ace S 150 of 40 weight parts, 30 weight parts, 10 weight parts of sodium carbonate, 10 weight parts, 10 weight parts.
Then, this 4 example is added in the above-mentioned processed water, the state (diameter) of the solid floating matter that aggegation produces and the clarity of the top primary water after the aggegation are confirmed.Its result is as shown in table 1.
The relation (inanimate matter) of the clarity of solid floating matter and top primary water
| The solid floating matter | Clarity | |
| The A agent | × | × |
| The B agent | △ | △ |
| The C agent | ○ | ○ |
| The D agent | ◎ | ◎ |
◎ very good zero good △ is somewhat bad * and bad
1. only contain Tai-Ace S 150 ... ... ... the .A agent
2. Tai-Ace S 150+calcium sulfate+yellow soda ash ... ... the B agent
3. mixing+cement flour 2. ... ... the ..C agent
4. the agglutinant that generates by the present invention ... ... the ..D agent
Learn that by table 1 by the agglutinant (A agent) that Tai-Ace S 150 generates, though the aggegation effect is arranged, the solid floating matter that generates is very tiny, confirms that it can not make the sufficient gigantism of solid floating matter.It is floating that Shang Mian primary water partly has micropartical in addition, confirms that it does not have very fast sinking velocity and firm cohesive force.
This respect, the solid floating matter is compared in the B agent (being equivalent to host of the present invention) that has added the comparative example 2 of calcium sulfate and yellow soda ash in the A of comparative example 1 agent with the A agent diameter is very big, illustrates that its cohesive force is very high.Also therefore confirmed just can improve cohesive force by adding calcium sulfate and yellow soda ash in Tai-Ace S 150.This is because there is the significantly potential difference of calcium sulfate and yellow soda ash relative with the current potential of Tai-Ace S 150, by by alkali, acid or have numerical value and be separated by very far that the condensation effect that produces of conflicting each other of the material of current potential can form firm cohesive force.But because top primary water partly has some buoyant microparticals, illustrate that the proportion of the solid floating matter that the B agent by comparative example 2 produces is little, do not obtaining good effect aspect the speed of sinking.
Have a look the C agent of embodiment 1 below again, compare with the B agent solid floating matter state and above primary water part all very good.This is because cement forms the core of solid floating matter, has improved the proportion of solid floating matter in the time of the strong solid floating matter, has accelerated sinking velocity.This explanation can double as be the proportion dose also as the cement flour of pH regulator agent, is not the proportion dose that must increase other magneticsubstances.In the B agent, only add cement flour and just obtained the effect of making us being satisfied in the main with pH regulator agent and proportion dose dual-use function.
Next, the experimental result of having added in the C agent as the D agent of the embodiment 2 of the magneticsubstance ferrite powder of proportion dose proves, it is big that the solid floating matter becomes fully, further improved the proportion of solid floating matter when making solid floating matter gigantism by firm cohesive force, top primary water part has also had significant raising than C agent, has obtained very good effect.This explanation can obtain enough cohesive forces and sinking velocity by the present invention.Particularly the D agent of embodiment 2 has not only improved cohesive force and sinking velocity can also be as best embodiment.
