Abstract
The invention discloses a modifying method of modified mineralized rubbish, which comprises the following steps of: 1, crushing the mineralized rubbish and then screening to obtain powdery mineralized rubbish with a particle size of less than 60mu; 2, adding an alkylphenol polyoxyethylene ether solution in the powdery mineralized rubbish for modifying the powdery mineralized rubbish, wherein the modifying temperature is 30-90 DEG C, the modifying time is 20-150min, the pH value is 7-10, the mass concentration of the alkylphenol polyoxyethylene ether solution is 0.5-4 percent, the mass ratio of the powdery mineralized rubbish to the alkylphenol polyoxyethylene ether solution is 100:0.51-100:4; and 3, standing and then drying, then repeatedly washing with distilled water until foam disappears, and drying to obtain the modified mineralized rubbish. The modified mineralized rubbish obtained in the invention has excellent absorption property which is 2.31 times of that of the common mineralized rubbish; and the remarkable effect is obtained.
Description
Technical field
The present invention relates to a kind of modification mineralized waste and preparation method thereof.
Background technology
Active carbon has obtained extensive use in the fields such as processing of atmosphere absorption, difficult for biological degradation, poisonous and harmful waste water and micro polluted source as a kind of good adsorbent.But because its cost an arm and a leg (generally at 5000 ~ 12000 yuan/ton), processing cost is higher, has therefore limited its application greatly.
On the other hand, mineralized waste is meant that landfill reaches stabilisation for many years substantially in landfill yard, can exploit the rubbish of utilization.Compare with general soil, mineralized waste has that unit weight is less, porosity is high, the content of organic matter is high, cation exchange capacity (CEC) is big, absorption and the strong characteristics of exchange capacity, therefore is used as sorbing material.Yet though existing mineralized waste price comparison is cheap, its adsorbance is more limited, in being applied to industrialized sewage disposal, needs frequent desorb or replacing, has increased financial cost to enterprise.
Therefore, develop that a kind of absorption property is good, cheap, the novel absorption material of wide material sources, for environmental improvement contributes.
Summary of the invention
The object of the invention provides a kind of modification mineralized waste and preparation method thereof, to obtain the sorbing material of cheap and excellent adsorption.
For achieving the above object, the technical solution used in the present invention is: a kind of preparation method of modification mineralized waste comprises the steps:
(1), obtains less than 60 purpose powdery mineralized wastes with the mineralized waste grinding and sieving;
(2) add APES solution in above-mentioned powdery mineralized waste and carry out modification, modification temperature is 30 ~ 90 ℃, and modification time is 20 ~ 150min, and the pH value is 7 ~ 10, and the mass concentration of APES solution is 0.5 ~ 4%; The mass ratio of powdery mineralized waste and APES is 100:0.5 ~ 100:4;
(3) leave standstill the back filter and do, use the distilled water cyclic washing until lather collapse then, oven dry can obtain described modification mineralized waste;
Described modification mineralized waste Pyrogentisinic Acid's adsorption capacity is more than or equal to 1.0 mg/g.
Above, described APES solution is meant the aqueous solution of APES, and described APES is called for short op-10, and CAS number is 9016-45-9.
The adsorption capacity of described modification mineralized waste is meant to mass concentration to be the absorption property of the phenol solution of 45mg/L.
Optimized technical scheme, in the described step (2), modification temperature is 55 ~ 65 ℃, and modification time is 20 ~ 120min, and the pH value is 8, and the mass concentration of APES solution is 1 ~ 2.5%.
The present invention asks for protection the modification mineralized waste that above-mentioned preparation method obtains simultaneously.
Operation principle of the present invention is: utilize APES to form organic layer on the mineralized waste surface, thereby improve the absorption property of mineralized waste to polluting.
Because the technique scheme utilization, the advantage that the present invention compared with prior art has is:
1, the present invention has developed a kind of preparation method of new mineralized waste, and the modification mineralized waste that obtains has excellent absorption property, and its absorption property is 2.31 times of common mineralized waste; Under equal conditions, modification mineralized waste Pyrogentisinic Acid's absorption property and active carbon are suitable; Obtained significant effect.
, modification mineralized waste cost of the present invention is lower, has only about 1/5 of active carbon price, be suitable for applying.
, preparation method of the present invention is simple, production cost is low, the modification mineralized waste that obtains has excellent application value to the processing of atmosphere absorption, difficult for biological degradation, poisonous and harmful waste water and micro polluted source.
The specific embodiment
Below in conjunction with embodiment the present invention is further described:
Embodiment one
A kind of preparation method of modification mineralized waste comprises the steps:
(1), obtains less than 60 purpose powdery mineralized wastes with the mineralized waste grinding and sieving;
(2) in above-mentioned powdery mineralized waste, add APES solution and carry out modification (stirring 120min with agitator under the normal temperature), modification temperature is 60 ℃, modification time is 120min, and the pH value is 8, and the mass concentration of APES solution is 2%; The mass ratio of powdery mineralized waste and APES is 100:2;
(3) leave standstill after 1 hour with the vacuum filtration machine filter and do, then with distilled water washing 2 ~ 3 times until lather collapse, in baking oven,, can obtain described modification mineralized waste in 105 ℃ of oven dry.
Then under equal adsorption conditions, be that the phenol solution of 45mg/L is adsorbed to concentration, and compare that the result is as follows with active carbon, common mineralized waste:
Material | Common mineralized waste | The mineralized waste of embodiment one | Active carbon |
Adsorption capacity | 0.45mg/g | 1.04mg/g | 1.3mg/g |
From last table as seen, the modification mineralized waste that the present invention obtains has absorption property preferably, and is close with active carbon, and will exceed much than the adsorption capacity of common mineralized waste (being unmodified mineralized waste).
