The principle of the utility model embodiment is：
The technical terms that the utility model is related to includes adsorbent and coagulant, and the concept of the two is respectively：Adsorbent
It is some pollutants effectively to be adsorbed from sewage so that the material that sewage is purified；Coagulant is in water treatment procedure
In colloidal particles in water can mutually be bonded and the material that flocks together.The process of coagulation is exactly the mistake in water process
Coagulant is added in journey, pollutant is produced cohesion, the process of flocculation.Larger coarse grain suspension can utilize nature in sewage
Precipitation removes, but more small suspension, and even some harmful chemical ions, particularly colloidal particle settles very
Slowly, or even scattered suspended state can be kept for a long time in water and can not be sunk naturally, it is difficult to the method for natural sedimentation from water
In be separated off；The action principle of coagulant is to destroy the stability of these fine particles, contacts with each other it and condenses upon one
Rise, form floccule, and separation of sinking.
Element circular and its decontamination principle are as follows：
1st, ferrikinetics：Iron is constantly ground in ball mill, is difficult to form stable oxidation film on its surface, is made it
It can fully be contacted with the external world and various chemical reactions occur.Iron (makes iron get rusty mainly in malaria or dissolved with air
Oxygen in air) water in, easily oxidation form iron oxide (di-iron trioxide)；Iron oxide can form molysite with acid reaction
(such as iron chloride, ferric sulfate, ferrous sulfate, being common coagulant).In malaria, steel surface has adsorbed one layer thin
Thin moisture film, contain a small amount of H in this layer of moisture film+And OH-, oxygen has also been dissolved, has as a result formd one layer of electrolysis in steel surface
Matter solution, it forms countless small galvanic cells (because steel is impure) just with the iron in steel and a small amount of carbon；It is former at these
In battery, iron is negative pole, and carbon is positive pole, and iron loses electronics and is oxidized：
Negative pole：2Fe-4e-=2Fe2+(ferrous ion, is reducing agent, and frerrous chloride has exclusive decoloring ability)
Positive pole：2H2O+O2+4e-=4OH-
Continue to react after this：
Fe2++2OH-=Fe (OH)2(ferrous hydroxide, being adsorbent, coagulant)
4Fe(OH)2+O2+2H2O=4Fe (OH)3(iron hydroxide, is conventional coagulant, the iron hydroxide of gelatinous precipitate
Also there is stronger absorption property to pollutant)
Under anaerobic condition, Zero-valent Iron can act on degradable organic pollutant by light electrolysis：
Fe+2H2O=Fe2++H2+2OH-
With many components in sewage redox can occur for H2 and Fe2+, destroy the chromophore or auxochromes of dyestuff,
It is allowed to be broken, reaches decolouring purpose；They can also make macromolecular substances resolve into small molecule intermediates, make some difficult biochemical drops
The chemical substance of solution becomes the material of easy biochemical treatment, improves the biodegradability of sewage.
Zero-valent Iron can also degrade organohalogen compounds, and dechlorination process is all in the progress of the surface of iron；In the incipient stage of reaction,
Reality is based on suction-operated, and with the progress of reaction, after iron surface reaches adsorption equilibrium, rate of reduction gradually reduces；Iron
Particle it is thinner, its specific surface area is bigger, and adsorption capacity and chemical reactivity are stronger.
The pollutant of iron compound and its retention in mud eventually enters into mud cake, is sent into incinerator and burns, iron compound
It is changed into iron oxide, organic pollution burning mistake, forms clinker, clinker enters ball mill, through wet-milling, iron oxide and organic acid reaction
Molysite is generated, completes ferrikinetics.
2nd, aluminium circulates：Aluminium is constantly ground in ball mill, is difficult to form stable oxidation film on its surface, is made it
It can fully be contacted with the external world and various chemical reactions occur.Aluminium is active metal, the surface of the aluminium shape immediately in dry air
The dense oxidation film (aluminum oxide) that 50 angstroms of Cheng Houyue, aluminium is not further aoxidized simultaneously can be water-fast；Aluminium also can in humid air
Form one layer of oxide-film for preventing metal erosion；Aluminium is both sexes, that is, is soluble in highly basic, can also be dissolved in diluted acid.Aluminium and water it is anti-
Should be 2Al+6H2O=2Al (OH)3+3H2↑, reaction essence：Water is extremely weak electrolyte, but can ionize out in water hydrogen ion and
Hydroxide ion and reactive aluminum, generation Al (OH)3And H2, reaction condition, which can heat, to be carried out at normal temperatures, at normal temperatures its
Phenomenon is difficult to observe；It can be reacted according to the reproducibility deducibility aluminium of aluminium with water, but test and find, aluminium does not almost have with boiling water
Reacting phenomenon, therefore many people think that aluminium does not react with water.Actually this is not so, and can occurs aluminium with water vapour in a heated condition
Significant reaction, but react and prevent reaction from further carrying out with the oxygen generation dense oxidation film in water at the very start.
Aluminum oxide (Al2O3), amphoteric oxide, inorganic acid and alkaline solution can be dissolved in.
Aluminium and aluminum oxide and inorganic acid reaction generation aluminium salt (such as aluminum sulfate, aluminium chloride, being conventional coagulant).Aluminium and oxygen
Change aluminium and alkaline reaction generation aluminium hydroxide, be conventional coagulant.
The pollutant of aluminium compound and its retention in mud eventually enters into mud cake, is sent into incinerator and burns, aluminium compound
It is changed into aluminum oxide, organic pollution burning mistake, forms clinker, clinker enters ball mill, through wet-milling, aluminum oxide and alkali reaction generation
Aluminium hydroxide, complete aluminium circulation.
3rd, calcium circulates：In rubbish mud, calcium is mainly with calcium hydroxide (alkalescence, be conventional coagulant), lightweight carbonic acid
(also known as winnofil, its fine particles, surface are rougher, and specific surface area is big, therefore it adsorbs the ability of pollutant very for calcium
Form is present by force).
Calcium ion and its alkalescence can make some species precipitates：Lignin, in pH<9 or add calcium after start to precipitate；Fat, in pH<
8 or add calcium after start to precipitate；Humic acid, precipitated when adding calcium；Pectin, precipitated when adding calcium.
The pollutant of calcium compound and its retention in mud eventually enters into mud cake, is sent into incinerator and burns, calcium compound
It is changed into calcium oxide, organic pollution burning mistake, forms clinker, clinker enters ball mill, through wet-milling, calcium oxide and water reaction generation
Calcium hydroxide, complete calcium circulation.
4th, magnesium circulates：In rubbish mud, magnesium mainly exists in the form of magnesium hydroxide (alkalescence) colloid and Slurries, can
Play a part of coagulant.Magnesium Hydroxide Slurries have very big specific surface area, and adsorptivity is strong, activity is big, has very
Good mobility, suspension, non-settling, non-coherency, available for sewage adsorption bleaching, and being capable of absorption effluent very strongly
In lead, mercury, antimony, chromium, heavy metal and the harmful element such as arsenic so that sewage is purified.
Magnesium hydroxide can react with the phosphate radical in rubbish mud, ammonia nitrogen generates ammonium magnesium phosphate (guanite) precipitation,
Two kinds of pollutants of phosphide and ammonia nitrogen can be removed simultaneously.
The pollutant of magnesium compound and its retention in mud eventually enters into mud cake, is sent into incinerator and burns, magnesium hydroxide
It is changed into magnesia, ammonium magnesium phosphate is changed into magnesium pyrophosphate (ammonium therein is changed into nitrogen), organic pollution burns and lost, formation stove
Slag, clinker enter ball mill, through wet-milling, magnesia and water reaction generation magnesium hydroxide, magnesium pyrophosphate and acid reaction generation phosphoric acid
Magnesium (again can be with ammonia nitrogen reaction generation ammonium magnesium phosphate), completion magnesium and phosphorus circulation (because magnesium source and phosphorus source are all more expensive, it is achieved that
It recycles significant to reducing operating cost).
5th, mechano-chemical reation
