Description
Technical field
The present invention relates to a kind of preparation method and this kind of adsorbent of new adsorbent, can as the substitute products of traditional active carbon.
Background technology
Active carbon is one of most widely used water treatment agent of current field of water treatment, be usually used in the absorption of gas, isolation andpurification, the recovery of solvent, the decolorizer of liquid glucose, grease, glycerine, medicine, the deodorant of drinking water and refrigerator, nicotine-filtering medium in breathing mask, also can be used as the carrier of catalyst or metal salt catalyst.The raw material of early stage production active carbon is timber, xylocarp shell or beast bone, mainly adopted coal afterwards, activated carbon is obtained after destructive distillation, activation process, no matter utilize which kind of method, due to the unsustainable property that the raw material such as timber is produced, therefore seek alternative, high adsorption effect, continuable new adsorbent and there is wide application market space.
Summary of the invention
Object of the present invention, is solve the unsustainable property that existing acticarbon is limited to the raw material productions such as timber, and seeks a kind of novel alternative adsorbent and preparation method thereof.
Technical scheme of the present invention is as follows:
A preparation method for new adsorbent, is characterized in that, described method step is as follows:
(1) get the mud that contamination data analysis factory utilizes aerobic method process waste water to obtain, and slough moisture, make moisture percentage in sewage sludge lower than 85%;
(2) by anatase type nano titanium oxide: nano-silica powder: attapulgite: nano-sized magnesium hydroxide: nanometer manganese sesquioxide managnic oxide: magnetic Nano γ-di-iron trioxide mixes by the mass ratio of 1.5:1:2:1:1.5:1;
(3) mixture in step (2) is mixed by the mass ratio of 1:10 with the dewatered sludge mixture in step (1);
(4) high-temperature heating under nitrogen protection, is first rapidly heated to 400 degrees Celsius, maintain 400 degrees Celsius one hour, fast heating to 650 degree Celsius again, maintains one hour, then fast heating to 850 is degree Celsius to 900 degrees Celsius, maintain two hours, rear rapid cooling;
(5) take out, obtained Novel adsorption agent material.
A new adsorbent obtained according to described method, is characterized in that:
Contained by described adsorbent, salt is based on carbonate, and form carboxylic acid, phenol effectively can adsorb antibiotic effective group;
Specific area S
bET=150-250m
2/ g, adsorption capacity reaches 200-500mg/g; PH=8.5-10.
Further, the ratio of described adsorbent micropore and mesopore is between 0.2-0.3.
Beneficial effect of the present invention is:
The present invention is by selecting the dewatered sludge produced in sewage treatment plant's last procedure of sewage disposal to be raw material, under anaerobic be heated to 650-900 degree, and add certain micro-nano metal composition, ramped heating schedule 3-4 hour, the product finally obtained has certain specific area and a large amount of active group, have strong scale effect and structure effect, for pollutant particularly organic pollution there is high-affinity and adsorptive selectivity.Infrared spectrum analysis, at 1020cm
-1there is absworption peak at place, shows to exist Si-O (AI) and Si-O tetrahedron or silicon-aluminium (Al), silicon-oxo bridge.This material has very fast adsorption equilibrium speed and higher adsorption capacity, the performance of this type of material uniqueness particularly can be utilized to reduce the bioavailability of polluter, thus reach organic pollution materials in fixing soil, reduce and enter plant and namely reduce it and enter in biological chain, there is higher economic benefit and social benefit.
Detailed description of the invention
Specific embodiment: (1) gets the mud that contamination data analysis factory utilizes aerobic method process waste water to obtain, and sloughs moisture, makes moisture percentage in sewage sludge lower than 85%;
(2) get anatase type nano titanium oxide respectively, nano-silica powder, attapulgite, nano-sized magnesium hydroxide, nanometer manganese sesquioxide managnic oxide, magnetic Nano γ-di-iron trioxide be respectively 150 grams, 100 grams, 200 grams, 100 grams, 150 grams, 100 grams and mix;
(3) mixture in step (2) is mixed by the mass ratio of 1:10 with the dewatered sludge mixture in step (1);
(4) high-temperature heating under nitrogen protection, is first rapidly heated to 400 degrees Celsius, maintain 400 degrees Celsius one hour, then fast heating to 650 degree Celsius, maintain one hour, then fast heating to 850 degree Celsius maintains two hours, rear rapid cooling;
(5) take out, obtained Novel adsorption agent material.
Adsorbent of the present invention has certain specific area and a large amount of active group, has strong scale effect and structure effect, for pollutant particularly antibiotics organic pollution there is high-affinity and adsorptive selectivity.Contained salt, based on carbonate, defines carboxylic acid, phenol etc. and effectively can adsorb antibiotic effective group
Specific area S
bET=150-250m
2/ g, adsorption capacity reaches 200-500mg/g.
Infrared spectrum analysis, at 1020cm
-1there is absworption peak at place, shows to exist Si-O (AI) and Si-O tetrahedron or silicon-aluminium (Al), silicon-oxo bridge.
This adsorbent pH=8.5-10.
This adsorbent can by physical absorption antibiotics organic pollution in nonpolar Adsorption water, main cause is that this adsorbent has abundant carbonaceous micropore.
The ratio of this adsorbent micropore and mesopore is between 0.2-0.3.
