Description
Technical field
The present invention relates to a kind of production method of adsorbent, especially a kind of production method of novel sorbents.
Background technology
Adsorbent is the solid matter that effectively can adsorb wherein some composition from gas or liquid.Adsorbent generally has following characteristics: large specific surface, suitable pore structure and surface texture; Strong adsorption capacity is had to adsorbate; General not with adsorbate and medium generation chemical reaction; Easily manufactured, regenerating easily; There is good mechanical strength etc.Adsorbent can by classification such as pore size, grain shape, chemical composition, surface polarities, as gross porosity and pore adsorbent, powdery, granular, strip adsorbent, carbonaceous and oxide adsorbent, polarity and non-polar adsorbent etc., industrial conventional adsorbent has: silica gel, activated alumina, active carbon, molecular sieve etc.
But the production cost of traditional adsorbent is higher, and more biochemical sewage treatment plant, it is all activated sludge in mud, can burning disposal be carried out, need to consume a lot of energy, waste a lot of resource, but wholesome effect can not be brought, still there is residue to retain after process, just the impact of environment is reduced, but fundamentally can not solve the problem that waste residuum pollutes.
Summary of the invention
The object of the invention is to, a kind of novel sorbents production method utilizing the activated sludge of sewage treatment plant to make adsorbent is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of production method of novel sorbents, and its production method is as follows:
The first step: by wood sawdust 20-30 weight portion, clay 5-10 weight portion, the activated sludge 40-50 weight portion three of municipal sewage plant fully mixes;
Second step: the mixture first step obtained through belt filter press, plate and frame filter press or centrifuge dewatering, then entered sludge dryer, is reduced to 40%-50% by the moisture content of three's mixture;
3rd step: mixed with weight 4:1 with flyash by mixture after second step process, drops into temperature in incinerator and controls between 230-260 degree, burn and come out of the stove after 3-5 days, be cooled to room temperature, then through the flotation of screen cloth particle diameter.
The further setting of the present invention is: in the first step, and by wood sawdust 30 weight portion, clay 10 weight portion, activated sludge 50 weight portion of municipal sewage plant fully mixes.
The further setting of the present invention is: the mixture moisture content obtained in second step is 40%.
The further setting of the present invention is: in the 3rd step, incineration temperature is 260 degree, and the burning time is 3 days.
Said method can produce the adsorbent made new advances, said method burns after make use of the mud of sewage treatment plant and wood sawdust and clay mixed processing, define the adsorbent based on carbon, the sludge waste of sewage treatment plant re-uses by the present invention, be made into new commodity, reduce cost, also in a disguised form reduce pollution, can also turn waste into wealth simultaneously, improve energy utilization rate.
Detailed description of the invention
The production method of a kind of novel sorbents of the present invention, its production method is as follows:
The first step: by wood sawdust 30 weight portion, clay 10 weight portion, the activated sludge 50 weight portion three of municipal sewage plant fully mixes;
Second step: the mixture first step obtained through belt filter press, plate and frame filter press or centrifuge dewatering, then entered sludge dryer, is reduced to 40% by the moisture content of three's mixture;
3rd step: mixed with weight 4:1 with flyash by mixture after second step process, drops into temperature in incinerator and control between 260 degree, burn and come out of the stove after 3 days, be cooled to room temperature, then through the flotation of screen cloth particle diameter, then packaging becomes finished product adsorbent.
The raw material adopted in the present invention, cost is all very low, and adopts mud to be primary raw material, not only turns waste into wealth, and greatly reduces production cost.
A kind of preferred plan disclosed in the present embodiment, certain wood sawdust 20-30 weight portion, clay 5-10 weight portion, can proportioning arbitrarily within the scope of it between the activated sludge 40-50 weight portion three of municipal sewage plant, there is not restriction.
And in the present invention, reduce the moisture content of mixture, also can be the arbitrary numerical value between 40-50%, but more close to lower limit, better.
And the incineration temperature of incinerator can arbitrary temperature between 230-260 degree, burn time 3-5 days, 3-5 days arbitrary time, certainly, time usual incineration temperature is high, the time needed for burning is few, on the contrary then the burning time many.
The present invention utilizes wood sawdust, flyash carries out burning can obtain carbonizable substance, because clay is little containing the grains of sand, moisture is not easy to pass therethrough, clay plasticly comprises kaolin, halloysite, (<2 μm) aluminium silicate salt that particle is very little, except aluminium, clay also comprises a small amount of magnesium, iron, sodium, potassium and calcium, and containing abundant organic matter in activated sludge, after burning together, carbon is activated, form active carbon, product after burning has the electric polarity on larger apparent surface and its surface and abundant gap structure, directly can use as adsorbent.
Obviously, above-described embodiment is only used to done citing is clearly described, and the restriction not to embodiment.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still in protection scope of the present invention.
