Abstract
The invention relates to a production method of an adsorbent, and especially relates to a production method of a new adsorbent. The method comprises the following steps: 1, fully mixing 20-30 parts by weight of wood sawdust, 5-10 parts by weight of clay and 40-50 parts by weight of activated sludge in a municipal sewage treatment plant; 2, dehydrating the mixture obtained in step 1 by allowing the mixture to go through a belt filter press, a plate and frame filter press or a centrifuge, and allowing the dehydrated mixture to enter a sludge dryer to reduce the water content of the mixture to 40-50%; and 3, mixing the mixture obtained in step 2 with coal ash according to a weight ratio of 4:1, adding the new mixture to a burning furnace, burning at 230-260DEG C for 3-5 days, cooling to room temperature, and carrying out particle size flotation through a screen mesh to obtain the new adsorbent. The new adsorbent produced through the method has the advantages of realization of the recycle of sludge wastes in the sewage treatment plant to make a new product, cost reduction, pollution reduction, realization of the change of wastes into valuables, and energy utilization rate improvement.
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 effectively to adsorb the wherein solid matter of some composition from gas or liquid.Adsorbent generally has following characteristics: large specific surface, suitable pore structure and surface texture; Adsorbate there is strong adsorption capacity; Generally not with adsorbate and medium generation chemical reaction; Easily manufactured, easily regeneration; Good mechanical strength etc. is arranged.Adsorbent can be 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 adsorbent commonly used 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 carry out burning disposal, need to consume a lot of energy, waste a lot of resources, but can not bring wholesome effect, still there is residue to retain after processing, just the impact of environment reduced, but can not fundamentally solve the problem that waste residuum pollutes.
Summary of the invention
The object of the invention is to, provide a kind of activated sludge that utilizes sewage treatment plant to make the novel sorbents production method of adsorbent.
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: with wooden 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 that the first step is obtained is through belt filter press, plate and frame filter press or centrifuge dewatering, then advances sludge dryer, and the moisture content of three's mixture is reduced to 40%-50%;
The 3rd step: after second step is processed, mixture mixes with weight 4:1 with flyash, and in the input incinerator, temperature is controlled between the 230-260 degree, burns and comes out of the stove after 3-5 days, is cooled to room temperature, then passes through the flotation of screen cloth particle diameter.
The further setting of the present invention is: in the first step, and with wooden sawdust 30 weight portions, clay 10 weight portions, activated sludge 50 weight portions of municipal sewage plant fully mix.
The further setting of the present invention is: the mixture moisture content that obtains 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 be produced the adsorbent that makes new advances, said method burns after having utilized the mud of sewage treatment plant and wooden sawdust and clay mixed processing, formed take carbon as main adsorbent, the present invention is with the mud waste recycling of sewage treatment plant, be made into new commodity, reduced cost, also in a disguised form reduced pollution, can also turn waste into wealth simultaneously, improve energy utilization rate.
The specific embodiment
The production method of a kind of novel sorbents of the present invention, its production method is as follows:
The first step: with wooden sawdust 30 weight portions, clay 10 weight portions, the activated sludge 50 weight portion threes of municipal sewage plant fully mix;
Second step: the mixture that the first step is obtained is through belt filter press, plate and frame filter press or centrifuge dewatering, then advances sludge dryer, and the moisture content of three's mixture is reduced to 40%;
The 3rd step: after second step is processed, mixture mixes with weight 4:1 with flyash, and in the input incinerator, temperature is controlled between 260 degree, burns and comes out of the stove after 3 days, is cooled to room temperature, then passes through the flotation of screen cloth particle diameter, and then packing becomes the finished product adsorbent.
The raw material that adopts in the present invention, cost are all very low, and to adopt mud be primary raw material, not only turn waste into wealth, and greatly reduce production cost.
The disclosed a kind of preferred plan of the present embodiment, certain wooden sawdust 20-30 weight portion, clay 5-10 weight portion, between the activated sludge 40-50 weight portion three of municipal sewage plant in its scope proportioning arbitrarily, do not have restriction.
And the moisture content of reduction mixture in the present invention can be also the arbitrary numerical value between 40-50%, but more near lower limit, better.
And the arbitrary temperature of the incineration temperature of incinerator between can the 230-260 degree all can, burned time 3-5 days, 3-5 days arbitrary time all can, certainly, when incineration temperature is high usually, burn the required time few, on the contrary the burning time many.
the present invention utilizes wooden sawdust, flyash burns and can obtain carbonizable substance, because clay contains the grains of sand seldom, moisture is not easy therefrom to pass through, clay is the plastic kaolin that comprises, halloysite, (＜2 μ m) aluminium silicate salt that particle is very little, clay also comprises a small amount of magnesium except aluminium, iron, sodium, potassium and calcium, and contain abundant organic matter in activated sludge, after burning together, carbon is activated, form active carbon, product after burning have larger apparent surface with and the electric polarity on surface and abundant gap structure, directly can be used as adsorbent uses.
Obviously, above-described embodiment be only for explanation clearly do for example, and be not restriction 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 need not also can't give all embodiments exhaustive.And the apparent variation of being extended out thus or change still are in protection scope of the present invention.
