Description
Technical field
The invention belongs to environmental technology field, relate to the drinkable water industry, in particular, is the improvement method of various fluorine-containing drinkable waters.
Background technology
In the last few years, water pollution problems was more and more serious China's change, and it is many in the rural area particularly to contain high fluorine drinkable water; Aquosity circulation migration nature dissolves that to fluoridize object plane big, and industrial fluoride pollution face is little.Fluorine is the necessary element of human body; Lacked harmful, how poisonous; So containing the First Principles that high fluorine drinkable water takes care of oneself is " staying benefit " (staying 0.5-1ppm in drinkable water) " removing the evil " (unnecessary whole removing), also will " fill a vacancy " to lacking the fluorine area (area is adjusted) this is identical with treatment principle that other drinkable water dissolves element.
The inventor did removal of fluorine from water in 1994 at red soil.Develop three model machines and 200 fluorine remover for drinking water that galvanized iron is made.Though defluorination is effective, obtain license ZL96213527.5.Yet because of the casing corrosion with the Same Way defluorination is mistaken ideas day foldings.This investigates what the neighbouring area; Benefited a great deal, therefrom accumulated " achievement of seeking advice to practice " and specifically be summarised as:
1, substantially certainly " best to eat local water " also pollutes in the drinking water terminal it simultaneously and handles, treatment agent raw material wherein to be gathering materials on the spot, and adopts the method for biological self cleaning mineral lixiviation to make with what eat with optimization process, removes the evil and stays the benefit activatory edible and healthy water of filling a vacancy.
2, three anti-processing, promptly the water source is antifouling, drinking water diseases prevention, back anti-secondary pollution.The water source is antifouling: promptly preventing edible contaminated water source, mainly is that seepage maggot, the fly of pen, lavatory, rural area pollutes not only polluted source but also contaminate environment.The inventor has designed family, rural area sealing biological treatment sanitary privy in 1999 for Ji County for this reason, and the mandate ZL00250245 that patents.
3, must allow peasant user feel effectively, reliable, convenient, economical, this is more than 300 villages and small towns that the inventor has visited 21 provinces for over ten years, through trial-production, the achievement that obtains after revising is used in experiment.
Drinking water diseases prevention: promptly eat local edible and healthy water.The few of safe edible health care water eaten in the whole nation at present; As city tap-water, because of being subjected to secondary pollution or sneaking into sewage, sterilizing agent, halide water etc. make the water supply terminal problem of aspects such as sense of smell, vision, the sense of taste often occur, and are offensive; China has 300,000,000 urban populations eating similarly tap water.For rural area, fishing, herd, the edible dangerous water problems of exploration, military camp sentry post, disaster area outlying mountain area is even more serious, Jie's water-borne infection disease that happens occasionally is as cholera, typhoid fever dysentery bacterium, hepatitis, gland, bone marrow poliomyelitis virus, merchant Di Shi protozoon and the multiple communicate illness that jeopardizes human body.Aquosity natural pollution for another example, for example fluorine, iodine, selenium, the ionic compound in water is many concerning human body, lacked and all cause skeletal fluorosis, Tiroidina Keshan disease or the like.Even if magnesium and silicon, sulfate radical and selenium the people intravital out of proportion also be one of the reason of Kaschin-Beck disease.
Summary of the invention
The purpose of this invention is to provide the improvement method of various fluorine-containing drinkable waters, the present invention adopts following technical scheme:
The improvement method of the various fluorine-containing drinkable waters of the present invention is characterized in that, it comprises the pending following plurality of processes of fluorine-containing drinkable water process:
(1) at top water filling port 1, manually inject or connect tap water through stopping valve inject former fluorine-containing drinkable water in water injecting tank 10 and aeration leak again and be good oxygen condition; Through the katalysis of manganese sand 2, quartz 3, make iron in the water, aluminium, manganese, silicon etc. form complex compound colloid, both remove some heavy metals and helped removing organism; Then through 4 carbon cottons, 5 filter bowls, filter screen 6, cross dish female 7, connect mouth 8, hose adapter 9 injects lauter tubs 13, enters anaerobic treatment stage;
(2) enter the fluorine-containing drinkable water of anaerobic treatment stage through percolation treatment agent 18; Bucket 14 in changeing upward by interior bucket 13 is fallen by outer bucket 15 again, crosses by pallet 16 sintered body supported 17, filters to flow in main bucket 11 to store;
Again through excellent filter 19, provide safety, edible health water when (3) eating by tap 20;
Treated dose of processing of wherein fluorine-containing former drinkable water flowed out by treater, and treated dose of processing of the fluorine-containing drinkable water in its Central Plains flowed out by treater, and lixiviation parameter cross section is 78cm
2, flow velocity liter/6 minute, the PH that reserves water is 7.20-7.50.The number that should guarantee bacterium in every ml water is less than 100/ml bacterium, and colibacillary number is less than 3/L intestinal bacteria in every ml water.
The content of each ion component is as follows in the drinkable water after treated dose of processing: that must remove unnecessary ion component accounts for 12%, all filtering accounts for 7%, that must augment accounts for 6%, produce metathetical and account for 10%, remaining accounts for 65%, and manganese sand of the present invention and quartzy volume are the 1/3-1/5 of water storage.Sintered compact 17 of the present invention refers generally to the sintering processes agent, for example the husky sintered compact of medical stone, slag, sulphonated coal, quartz, manganese and with the diatomite that contains the aluminosilicate structure or sintered compact or the like; Generally be with more than the raw material preheating to 100 ℃, add high density polyethylene(HDPE) and carry out hot-forming.Excellent filter mainly refers to the magnetism that 600 Gausses are housed or magnetizing apparatus is housed, and reaches the disinfectant effect.
Principle of work referring to Fig. 1 signal:
(1) be that water filling port 1 injects artificial or connects tap water and injects former drinkable water through stopping valve and reach aeration leak again and be good oxygen condition in water injecting tank 10 on top.Katalysis through manganese sand 2 and quartzy 3 makes iron in the water, aluminium, manganese, silicon etc. form complex compound colloid, has both removed some heavy metals and has helped removing organism.Coil mother 7, connect mouth 8 and hose adapter 9 injection lauter tubs 13, enter anaerobic treatment stage through 4 carbon cottons, 5 filter bowls and filter screen 6, mistake then.
(2) all filtrates 18 of diafiltration; By interior bucket 13, middle bucket 14 in the commentaries on classics is fallen by outer bucket 15 again, crosses the sintered compact of being made by pallet 16 17, and filter is flowed in master's bucket 11 and stored.Again through excellent filter 19, provide the safe healthcare drinkable water when edible by tap 20.
The improvement method of fluorine-containing drinkable water of the present invention further comprises:
(1) aerobic treatment: can carry out the conventional processing technology that novel material is facilitated, little aeration, coagulation, precipitation, clarification, filtration, oxygen consumption removal of microorganisms dissolved organic matter, sterilization, photosynthesis and radioactive contamination eliminating etc.Especially to the filtering of 1-100nm particulate, based on coagulation, mainly be to remove electronegative colloidal solid, the colloidal solid in the both former drinkable water is adsorbed on the flock of ferro-aluminum oxyhydroxide.The processing of fluorine-containing drinkable water is mineral, the microorganism self-purification to former drinkable water from start to finish, leaves regular hour, space, and complementation, scrubbing, repairs, stays benefit, natural effect excellent.
(2) anaerobism lixiviation place is buried: former drinkable water is from treated dose of top box, and seepage is in following " lauter tub ".By lixiviation operation and required multiple respective handling agent, fill lauter tub in the bucket.1/5 of the approximately suitable water storage of treatment agent volume.Adopt of treatment agent imitated natural mineral more, former drinkable water carried out lixiviation handle; Be the lixiviation of volcanic rock, rock, magmatic rock and metamorphosed rock, the lixiviation of katatectic strata (salt) and oxidized mineral (yellowish-brown iron ore) etc.Replace absorption, decarbonate and biochemical action with concentrated, mixing, positively charged ion simultaneously.The effect of mineral lixiviation.Mainly be to allow necessary ion component and ionic concn change when drinkable water seepage flow is crossed the mineral processing agent.This with thought in the past; Solute is detained, and the lixiviation effect of concentration step-down is distinguishing.
Wherein said treatment agent comprises: natural mineral treatment agent, weathered clay treatment agent, zwitterion treatment agent, imitative natural mineral treatment agent.For example activated alumina, lime, Tai-Ace S 150, hydroxyapatite, alumina, bone ash, composite mortar, zeolite, medical stone, gac, slag, flint clay, cement, shell or the like.
The important factor that influences absorption property is the ligand structure layer of mineral, specific surface area, ionic valence, ionic radius, acid-alkali medium, granularity, temperature and essential ionic concn.It is exactly the power of lixiviation that the oozing from the mountain of its concentration difference and water falls.Filtering velocity promptly is the head loss of water filter, and under the condition that the lixiviation parameter is determined, water level is to rise/78 flat ten thousand centimetres/6 minutes to the derivative of time.Filtering velocity is intermittently, and water intermediate ion concentration is the person's of needing instantaneous flow by increasing, and removes person's instantaneous flow by subtracting, and the improper integral of increase and decrease function curve is a saturated extent of adsorption, and the constant volume of threshold values is divided into the active adsorption amount, measures the calculating recovery time with this.The above is after treatment agent is handled former drinkable water, to the concentration or the molten amount of needed by human body element, illustrates that mineral are that main fluorine-containing drinkable water is handled in the maintenance drinkable water; Only handle 1/3rd, promptly remove the evil and stay benefit to fill a vacancy.2nd/3rd, kept the former water quality that local human body adapts.
(3) main water storage box: the main box of promptly fluorine-containing drinking water treatment system, bottom hold storage 1-2 day, the drinkable water of handling well.And can add magnetism or ultrasonic disinfection device in the depotition cock ingress.Water storage box each family terminal that supplies water---need use leading Drinking water apparatus, filtering suspended substance and protozoon etc.As the tap water terminal bury secondary pollution with the Drinking water apparatus place, the fluoride-removing can that do in a lot of villages is all discarded, finds when removing afterwards; The activated alumina of white has reddened the iron rust ball entirely.So defluorination must first deironing.Containing simultaneously hydrocarbonate, halogen, vitriol in the drinkable water of different areas exceeds standard.So drinkable water has hardship, salty, astringent taste mostly.Absorption positively charged ions such as this available sulphonated coal, montmorillonite are handled in the medical stone sintering body with the diatomite that contains the aluminosilicate structure or sintered compact adsorpting anion or with the zwitterion resin absorption.Should desalination defluorination but must keep the value of cutting off from again, but can not Ex-all.The drinkable water fluorine is handled; Defending the standard laid down by the ministries or commissions of the Central Government, to decide threshold values be 1PPM, and its treatment agent can be gathered materials on the spot, and all can with shell, activated alumina, bone ash carbon, zeolite, laterite etc.
The present invention just represents fluorine-containing drinkable water treating processes and principle emphatically; Be according to carbon face end liner as the water injecting tank of aerobic treatment, form the biological treatment of similar active sludge, fine to the organism treatment effect.Can be with 560 dust light pipes when handling high iodine.Phase body volume of the present invention is decided according to water storage, and generally day to eat the 4-5 premium on currency for each person every day, family retaining every day can guarantee running water with eating with processing for 25 liters.
