Description
Technical field
The present invention relates to active carbon preparation technical fields, and in particular to a kind of sewage dephosphorization CharcoAid and its preparation work
Skill.
Background technique
It is poor in the prevalence of active carbon stability, absorption property is irregular not at present in the research of active carbon dephosphorization
Together, the too long problem of adsorption time.In order to improve active carbon to the absorption property of phosphorus, the side of modification is generallyd use both at home and abroad
The pore structure, surface functional group and raising energy of phosphorus agent are inhaled in formula, such as adjustment, are increased with generating the component of precipitated product with phosphorus
Inhale phosphate capacity.By taking rice hull active carbon adsorbent as an example, specific surface area 886.3m2/ g, the maximum saturation adsorbance to phosphorus are
6.93mg/g.Therefore, utilize the physical absorption of active carbon to be used for sewage dephosphorization merely, absorption property is lower and time of equilibrium adsorption
It is longer, lead to that the sewage treatment time is long, production efficiency is low.
Summary of the invention
The object of the present invention is to provide a kind of sewage dephosphorization CharcoAid and its preparation processes, to improve sewage dephosphorization effect
Fruit.
In order to solve the above-mentioned technical problems, the present invention provides a kind of dephosphorization CharcoAids, comprising: active carbon particle and
Calcic powder；And the active carbon particle is suitable for the absorption carrier of calcic powder.
Further, the calcic powder includes: porous calcium carbonate；And the covalent bond that the porous calcium carbonate contains is suitable for
It is reconfigured with the high energy covalent bond inside active carbon particle.
Another aspect, the present invention also provides a kind of preparation process of dephosphorization CharcoAid, using active carbon particle as
The absorption carrier of calcic powder, so that the two is uniformly mixed.
Further, described using active carbon particle as the method for the absorption carrier of calcic powder includes: by active carbon particle
It mixes, roast with calcic powder；It is passed through vapor in roasting process, is 60-80% to keep roasting humidity.
Further, the maturing temperature is 100-250 DEG C；Calcining time is 1-3h.
The invention has the advantages that dephosphorization CharcoAid of the invention passes through using active carbon particle as calcic powder
Absorption carrier, both make to be uniformly mixed；Calcic powder can be by the carrier function of active carbon particle, and expansion connects with sewage
Contacting surface, a large amount of calcium ions formed after autolysis can be reacted with the phosphate radical in sewage, generate the phosphoric acid with micro dissolution
Ca-deposit, to reach sewage dephosphorization purpose；Meanwhile active carbon particle may also speed up diffusion speed of the calcic powder in sewage
Degree avoids calcic powder from precipitating or be deposited in sewage bottom, improves the efficiency of sewage dephosphorization.
Specific embodiment
Embodiment 1
The present embodiment 1 provides a kind of dephosphorization CharcoAid, comprising: active carbon particle and calcic powder；And the activity
Charcoal particle is suitable for the absorption carrier of calcic powder.
Optionally, the calcic powder includes but is not limited to: porous calcium carbonate；And being total to of containing of the porous calcium carbonate
Valence link is suitable for reconfiguring with the high energy covalent bond inside active carbon particle.Porous calcium carbonate and common calcium carbonate difference
It is that porous calcium carbonate is easier to be adsorbed by active carbon particle, and penetrates into inside active carbon particle (in macropore, mesoporous or micropore),
And the high energy covalent bond inside active carbon particle can with the covalent bond of porous calcium carbonate the same constant entropy energy the case where group again
It closes, it is not easy to separate, reach long-term sewage dephosphorization effect, without being dissolved in the short time, to lose phosphor-removing effect.
Optionally, the active carbon particle is such as, but not limited to wood activated charcoal, coaly activated carbon, rice hull active carbon or coconut palm
Various cavernous structures are distributed in shell active carbon etc., surface, such as surface macropore, transition mesoporous, internal capillary.In the present embodiment 1
In by the way that active carbon particle is roasted together with calcic powder, so that calcic powder is transitioned into mesoporous from macropore, be finally sufficient filling with
Or be adsorbed in micropore, the adsorbance of calcic powder is higher by 3-4 than being adsorbed on the adsorbance of active carbon particle outer surface merely
Four times.
Since activated carbon density is smaller, the density of general particle column-shaped active carbon is 0.45g-0.65g/cm3, powder activity
The density of charcoal is 0.38g-0.45g/cm3, and the specific gravity of water is 1g/cm3.Therefore, calcic powder can exist by active carbon particle
Buoyancy in sewage is diffused, and calcic powder is avoided to precipitate or be deposited in containing in sewage bottom, especially mesoporous or micropore
Calcium powder material can be not only diffused, but also can improve phosphor-removing effect to avoid the problem of water fails immediately is met.
The dephosphorization CharcoAid of the present embodiment 1 is by making two using active carbon particle as the absorption carrier of calcic powder
Person is uniformly mixed；Calcic powder can expand the contact surface with sewage, after autolysis by the carrier function of active carbon particle
The a large amount of calcium ions formed can be reacted with the phosphate radical in sewage, the calcium phosphate precipitation object with micro dissolution be generated, to reach
Sewage dephosphorization purpose；Meanwhile active carbon particle may also speed up diffusion velocity of the calcic powder in sewage, avoid calcic powder
Sewage bottom is precipitated or be deposited in, the efficiency of sewage dephosphorization is improved.In addition, porous calcium carbonate is easier to be inhaled by active carbon particle
It is attached, and penetrate into high energy covalent bond inside active carbon particle and inside active carbon particle and can be total to porous calcium carbonate
Valence link is reconfigured in the case where same constant entropy energy, it is not easy to be separated, to reach long-term sewage dephosphorization effect.
Embodiment 2
On the basis of embodiment 1, the present embodiment 2 provides a kind of preparation process of dephosphorization CharcoAid, by active carbon
Absorption carrier of the grain as calcic powder, so that the two is uniformly mixed.
Optionally, the calcic powder includes but is not limited to calcium carbonate, especially porous calcium carbonate.
Constituent content and specific implementation process about dephosphorization CharcoAid are discussed referring to the correlation of embodiment 1, herein
It repeats no more.
Further, described using active carbon particle as the method for the absorption carrier of calcic powder includes: by active carbon particle
It mixes, roast with calcic powder；It is passed through vapor in roasting process, is 60-80% to keep roasting humidity, preferably humidity is
70%。
Optionally, the maturing temperature is 100-250 DEG C, preferably 150 DEG C, 200 DEG C；Calcining time is 1-3h, preferably
For 1.5h, 2h.Porous calcium carbonate powder with active carbon particle during roasting, by adjusting maturing temperature, humidity and roasting
The time is burnt, porous calcium carbonate powder can be made to be adsorbed by active carbon particle, and is penetrated into inside active carbon particle and active carbon
High energy covalent bond inside particle can be reconfigured with the covalent bond of porous calcium carbonate in the case where same constant entropy energy, it is not easy to point
From to achieve the effect that long-term sustained release dephosphorization.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
