The invention relates to a kind of manufacturing installation (claim 8) of deodorised drinking-water, feature is to have to make rivers and lakes water and contain pore surface and adsorb the treatment unit of decompose odor composition for the treatment agent of amorphousness porous ceramics contacts.According to the deodorised drinking-water manufacturing installation (claim 9) of claim 8 record, feature is the treatment unit with flocculation sediment treatment unit and absorption decompose odor composition.According to claim 10), feature is filtration treatment device, flocculation sediment treatment unit that has rivers and lakes water successively and the treatment unit that adsorbs the decompose odor composition.Deodorised drinking-water manufacturing installation (claim 11) according to each record among the claim 8-10, feature is that the treatment unit of absorption decompose odor composition is by splendid attire rivers and lakes water and contains the treatment agent that the pore surface is the amorphousness porous ceramics, top is open, and the open aeration tank of retention of being carried out aeration by the bottom is constituted.
Manufacture method as deodorised drinking-water of the present invention, be to make rivers and lakes water and contain pore surface and contact for the treatment agent of amorphousness porous ceramics, the treatment process of the foul smell composition in the water of rivers and lakes is decomposed in absorption, but this there is not particular restriction, and as deodorised drinking-water manufacturing installation of the present invention, be to be used to make rivers and lakes water and to contain the pore surface contacted for the treatment agent of amorphousness porous ceramics, have the device of treatment unit of the absorption decompose odor composition of the above-mentioned treatment agent of splendid attire, this is not had particular restriction yet.Said herein " the pore surface is an amorphousness " is meant that the surface at the inner continuous pore that forms of pottery has simultaneously with the water glass surface of the amorphousness and the crystallines such as water glass and calcium oxide (crystallinity particle) that are principal constituent.Crystalline (crystallinity particle) part becomes to grade with foul smell and reacts, but the amorphousness part can not reacted.
Utilize the radio scanning electronic microscope S-4200 type of Hitachi Co., Ltd's system to observe [acceleration voltage 10KV (secondary electron image) and 20KV (reflection electronic picture, under the condition of 3000 times of multiplying powers of photography] during the continuous pore surface that in porous ceramics, forms, can think, on the pore surface is not in the old type porous ceramic of amorphousness, as shown in Figure 1, not only the ceramic particle surface 1, and the most surfaces of continuous pore 2 is covered by crystallinity particle 3, foul smell becomes to grade on the logistics 4 arrival ceramic particles, promptly enable by in the continuous pore 2, but resistance is very big, foul smell becomes to grade fully to flow into and is impregnated in the pore 2, to the favourable surface that only limits to ceramic particle 1 of reaction that becomes to grade with foul smell, in contrast, in the present invention in the surperficial amorphousness porous ceramics of Shi Yonging, as shown in Figure 2, on the surface of continuous pore 2, there is level and smooth amorphousness part 5, when the logistics 4 that foul smell becomes to grade arrives ceramic particle, resistance by in the continuous pore 2 time is very little, foul smell becomes to grade to flow into fully and is impregnated in the pore 2, like this, the surface 1 of ceramic particle not only, and the crystallinity particle 3 that exists in pore 2 can become to grade and react with foul smell, and the result acquires the treatment effect that good foul smell one-tenth grades.
As the present invention adsorb use in the disaggregating treatment contain the treatment agent of pore surface as the amorphousness porous ceramics, be amorphous porous ceramics if contain the pore surface that to adsorb foul smell composition in the water of the tedious rivers and lakes of disaggregating treatment, this there is not particular restriction, as the pore surface is amorphous porous ceramics, as mentioned above, also can be to resemble to exist level and smooth amorphousness part such on the continuous pore surface that in porous ceramics, forms, this pore surface is amorphous porous ceramics, for example can modulate as follows, promptly, with clay, pore forms material and water mixes, after being processed into suitable shape, drying, for this drying and moulding body finished product temperature, can form the spontaneous ignition temperature of material according to pore in the formed body, be set in 5～15 hours, be warmed up to 600～800 ℃ from normal temperature, after keeping 3-7 hour under 600～800 ℃, be warmed up to 1200～1500 ℃, after burning till 4-8 hour under 1200～1500 ℃, carry out break process.
As making surperficial " clay " of pore for using in the amorphousness porous ceramics, be when adding moisture, to present binding property and plasticity-, character with exsiccation and hardening, its major part is made of the clay mineral that with the silicate minerals is principal constituent, though this is not had special formulation, can contain other inorganic components such as calcium, magnesium, sodium, potassium yet.
As make the pore surface for " the pore formation material " that use in the amorphousness porous ceramics from plant, sawdust, wood chip, rice husk, straw, wheat bran, bark (wooden skin), also can use plastics bits, granular absorptivity polymer, sodium bicarbonate etc., as long as by adding thermogenesis gas, the sort of can the use, but sawdust, wood chip can not produce violent gas at self-combustible stage, with regard to stablizing formation pore surface is the structure this point of amorphousness porous ceramics, is good.
As making " water " of pore surface for using in the amorphousness porous ceramics, though can use common tap water, the alkali composition also can use seawater seldom the time in other clay minerals.Forming as the clay of other raw materials, pore when containing moisture in the material, also can substitute with these moisture.As the tackiness agent that makes in the water, also can add 0.5%～2.0% polyethylene, polypropylene, EVA resin, metha crylic resin, polymkeric substance (polyacetal, cellulose-based) and other plants starch powders etc. of (weight %, below identical) with ehter bond.
On the pore surface is in the manufacture method of amorphousness porous ceramics, and clay, pore form " mixing " of material and water, be with this with suitable order, mix with mullers such as cement plaster blenders, up to evenly.The ratio of mixture of these compositions, as long as the pore surface that can obtain to use among the present invention is the amorphousness porous ceramics, can with any ratio, even so, but, for example forming material 6～7: water 1～3: when the ratio of clay 2 (weight part, following identical) mixes, make moisture fully be immersed in pore and form in the material with pore in order on the continuous pore surface, to form more amorphousness part, then add powdered clay, mix.Subsequently, in order to be easy to burn till, can be processed into brick shape, suitable shape such as discoid.
On the pore surface is in the manufacture method of amorphousness porous ceramics, and " drying " after the moulding is static depositing under common room temperature, makes water ratio reach 40%, also can use roasting kiln etc., by air seasoning etc., implement, be not limited in above-mentioned standing and drying.
Be " intensification " and " burning till " in the manufacture method of crystalloid porous ceramics on the pore surface, electric furnace, kiln that is built into refractory brick or kiln etc. are as long as can heat above-mentioned dried formed body, burn till, any can use, but from going out the consideration of uniform ceramic aspect, preferably kiln or kiln by a mass production.
On the pore surface is in the manufacture method of amorphousness porous ceramics, and the formed body after burning till though it directly can be used as the strainer of monoblock shape or tubular, preferably carries out fragmentation (pulverizing) and handles.By carrying out can being obtained particulate state by broken processing, the powder of finely powdered expands into the very thin film that burns till on the particulate state surface, by utilize the current potential that generates on porous matter section and wall, can more effectively carry out deodorization and handle.In this break process, can use known pulverizers such as roll-type, extrusion pressing type, as roll-type crusher, specifically can enumerate the roll-type crusher that the slit between roller and the roller partly is adjusted into 10～30mm, as pulverizers such as extrusion pressing types, specifically can enumerate the extrusion pressing type crusher that can on formed body, form 2cm four directions trellis ditch.
Below be elaborated for most important " intensification " in the amorphousness porous ceramics and " burning till " operation to making the pore surface.
At first, the formed body temperature of articles of moulding after drying slowly is raised to 600～800 ℃ from normal temperature, best 800 ℃, by adopting this slow temperature-rise period, ceramic proterties behind the sintering is kept and roughly the same shape during the formed body manufacturing, form on one side sufficient continuous pore, form and handled thing have the part of abundant reaction on one side.On the other hand, when not adopting this slow temperature-rise period, and use electric furnace etc., when adopting the temperature-rising method of temperature-rise period rapidly, the combination of pottery behind the sintering between crystallised component is inadequate, simultaneously, the pore surface that forms in pottery is most of to be covered by crystalline, in the time of in foul smell becomes to grade by pore, it is very big that resistance becomes, and forms to have foul smell and become to grade and can not fully be impregnated into the pottery of this character, proterties in the pore, using it for when removing foul smell and becoming to grade, it removes inevitable insufficient, also can not get the goods of anti-life-time service.
This needed time of intensification that is warmed up to 600～800 ℃ lentamente from normal temperature according to the size and the quantity of forming composition, is generally about 5-15 hour, roughly carry out 10 hours best.Though controlling this intensification can heat by the heating of regulating electric furnace, kiln and kiln and implement, when pore forms material and is inflammable substance such as sawdust, preferably by an angle point combustion with the drying and moulding body, for example with burner etc., make flammable pores such as sawdust in the formed body form material self burning (spontaneous combustion) and carry out.The control method of utilizing this spontaneous combustion to form products temperature is, with regard to accent is equipped with the porous ceramics aspect, the method that present inventors find first with picture significance of times, and confirmed by adopting this method, can obtain the pore surface and be amorphous ceramic.
Like this, at time spent 5-15 hour, the products temperature of drying and moulding body is being reached in 600～800 ℃ of stages the complete ashing of combustiblematerialss such as the sawdust in the formed body.In this stage, continue to keep burning etc., 600～800 ℃ temperature were kept 3-7 hour, preferably kept 5 hours.Just make the pore surface and say that for the amorphousness porous ceramics this operation is very important operation, by adopting this operation, the slowly stripping of alkaline components in the clay, as a result, the continuous pore of porous ceramics surface forms amorphousness, has increased the intensity of porous ceramics behind the sintering.If do not adopt this operation, still undertaken by method in the past, once when normal temperature was warmed up to 1200～1500 ℃, the ceramic mass after burning till not only produced deviation, and it is also undesirable to remove the performance that foul smell becomes to grade.
At 600～800 ℃ of formed bodys that heat 3-7 hour down, be warmed up to 1200～1500 ℃ with 4 hours again.As 1200～1500 ℃, its firing temperature has certain amplitude, and its reason is that the amount of silicon-dioxide in the clay and alkaline components is controlled, as burning till the result, can obtain different active surfaces, that is, the alkaline components in the clay is many, when sintering is easy, can adopt 1200 ℃, when the silicon composition is many, when being difficult to sintering, can adopt 1500 ℃ sintering.If the finished product temperature of formed body was burnt till under this temperature 4～8 hours when reaching 1200～1500 ℃, preferably burnt till 6 hours.When the firing time under this temperature was 1 hour, the amorphous materialization on the continuous pore surface of formation was insufficient, can not get the abundant sintering strength with ambient particles, and the result can only obtain having the pottery of fragile shortcoming.
As the present invention adsorb use in the disaggregating treatment contain the treatment agent of pore surface as the amorphousness porous ceramics, be the mixture of pore surface for amorphous porous ceramics and gac, for example 30～70: 70～30 mixture, preferably 50: 50 mixture.As this " gac ", if charcoal, coconut husk, coal, raw materials such as other animal bone and blood are made through abundant charing, can be any, if having bigger serface, and high adsorption capacity.By the material that porous carbon forms, be not limited in that existing market sells.
Can use the treatment unit of absorption decompose odor composition in the absorption disaggregating treatment in deodorised drinking-water manufacture method of the present invention, as the absorption disaggregating treatment of using this foul smell composition absorption decomposing processor, can make rivers and lakes water and contain pore surface and under aeration, contact for the treatment agent of amorphousness porous ceramics, preferably use the open aeration tank of retention, splendid attire rivers and lakes, the inside water is the treatment agent of amorphousness porous ceramics with containing the pore surface, top is open, carries out aeration from the bottom.As this " the open aeration tank of retention ", it can be any normally used opening aeration tank, for example there is top to be open, the bottom connects air leading-in conduit, the air that utilizes air compressor machine or gas blower to import, be dispersed in the pond by orifice plate that is located at the pond inner bottom part or scatterer, carry out aeration.The best retention of processed liquid is in the pond in the aeration, aeration speed, per 1 minute 1m
3, from 50L to 200L, preferably about 100L.When surpassing 200L/ minute m
3The time, can excite ceramic moving in the water, because the collision each other between the pottery can make the wearing and tearing aggravation, when being lower than 50L/ minute m
3The time, processed water by same place, makes the porous ceramics of input can not give full play to its function easily.
Remove the above-mentioned treatment agent of exhausted in the foul smell composition in absorption, for example,, can regenerate being the treatment agent that the mixture of amorphousness porous ceramics and gac forms by the pore surface.As renovation process, there is not particular determination, can adopt the mode of counter flow washing, for example, close the relief outlet of the open aeration tank of retention, make washing water overflow to 30～100cm above the treatment agent layer, best 50cm, maximum increases the air import volume in the aeration, carries out counter flow washing.
In deodorised drinking-water manufacture method of the present invention, as the operation before the absorption disaggregating treatment foul smell composition, preferably use the flocculation sediment treatment unit, the trickle outstanding absurd creature in the water of rivers and lakes is carried out flocculation sediment handle.As " flocculation agent " that use in this flocculation sediment processing, as long as the cohesion of the trickle outstanding absurd creature (SS) in the draining can be formed the just passable of block (glomeration), this there is not particular determination, for example can use iron(ic) chloride (FeCl simultaneously
3), inorganic flocculating agent such as Tai-Ace S 150, calcium hydroxide and the macromolecule organic flocculating agent that forms by tensio-active agent or high score flocculation agent.For example, processed water is modulated to acid PH3.5 with ferric chloride Solution, behind the placement certain hour, returns near neutral PH 7.0 with sodium hydroxide solution again, (can confirm at this moment to have produced tiny cohesion) then adds polymeric flocculant and forms big block.Return to neutrality with sodium hydroxide, when Fan Dewaershi power reduces once more, utilize polymeric flocculant to form bigger stronger block, can greatly avoid the SS composition to stop up continuous pore ceramic in the subsequent processing, thus but the function of long term maintenance pottery.As above-mentioned flocculation sediment treatment unit, concrete example is flocculation jar and the flocculation sedimentation tank with reagent solution buckets such as injecting ferric chloride Solution and polymeric flocculant.
In odorless drinking water preparation method of the present invention,, preferably use the filtration treatment device of rivers and lakes water, the solid sundries in the water of filtration treatment rivers and lakes as the last procedure that above-mentioned flocculation sediment is handled.As this filtration treatment device, can use the filtration unit that uses in the common water treatment with sand filter bed etc., this there is not particular determination, the filtration unit of for example concrete available maintenance 60～70cm thick sand bed that forms by the sand of particle diameter 0.3～2.0mm.
