Description
The present invention relates to a kind of water purification agent and manufacture method thereof, especially a kind of efficient water-purifying agent and manufacture method thereof.
In the prior art, water purification agent only contains single molysite or aluminium salt, adopts the industrial raw material manufacturing, thereby purifying water effect is relatively poor, leave residual look, production cost height; So far, also there is not a kind of water purification agent energy direct purification papermaking wastewater.
The purpose of this invention is to provide a kind of purifying water effect is good, the manufacturing is simple, with low cost efficient water-purifying agent and manufacture method thereof.
The objective of the invention is to realize by the multiple metal-salt that contains in the water purification agent.In order further to improve purifying water effect, also can contain the material of multi-cellular structure.
A kind of efficient water-purifying agent contains aluminium salt or molysite, is characterized in, also contains other metal-salts.Since contain other metal-salts, can be by the K in the water body
+, Na
+, NH
4 +Plasma displacement produces high valence ion, reduces or has eliminated colloidal solid
Current potential is in micelle and takes off steady state, and is easily coalescent, strengthened the floculation of aluminium salt or molysite greatly, improved purifying water effect.In order further to improve purifying water effect, also can contain the material of multi-cellular structure, utilize their absorption property, particulate absorption, coacervation, the precipitation in the water body, also adsorbable toxic substance plays disinfection.For the coacervation scope that makes efficient water-purifying agent is big, can contain aluminium salt and molysite simultaneously; The metal-salt of the same race that also can contain some kinds of acid groups simultaneously.
A kind of manufacture method of efficient water-purifying agent is characterized in: be raw material with the natural clay, or be raw material with granular high temperature rubbish or the natural rock mud of high temperature, add acid-respons and make.High temperature rubbish is meant those natural mineral or industrial refuse and the domestic refuse of earth after pyrotic smelting or calcining, as metal slag, coal ash, broken brick and tile etc.; This shows that the natural rock mud of also available high temperature is raw material, as: volcanics, scorched earth etc.Clay, high temperature rubbish, the natural rock mud of high temperature composition are all very complicated, but all contain multiple metal and compounds thereof such as iron, aluminium, after acid activation, can generate multiple metal-salt, the main component of clay is a silico-aluminate, also contain other metal ingredients, after acidifying, generate aluminium salt, other metals and have the fine silicic acid that helps the effect of coagulating; The natural rock mud of high temperature rubbish and high temperature burns the material composition that also contains the multi-cellular structure that differs in the aperture through the high temperature refining.In order further to enlarge the coacervation scope, improve purifying water effect, can simultaneously or successively add some kinds of acid and carry out acidifying; In order to improve clearance and decolouring, also can in raw material, mix granulous kaolin, zeolite or wilkinite; In order to guarantee thoroughly also saving acid of acidifying, the add-on of acid is 0.5～2 degree of being with pH value; In order to quicken acidization, improve purifying water effect, can under High Temperature High Pressure, carry out acidifying; In order to quicken acidifying, improve acidizing effect, the granularity of raw material is controlled at below 20 orders, and is the smaller the better.The water body that utilizes the present invention to handle, the clearance of CODcr can reach more than 95%, and pH value is between 6, and is colourless, and purifying water effect is good, can reuse, and have saved water resources greatly; The treatment of wastes with processes of wastes against one another is turned waste into wealth, and has protected environment effectively, has utilized resource fully; Manufacturing simply, easy to use, with low cost, applied widely, is unusual ideal water purification agent.
Below in conjunction with embodiment the present invention is described in detail:
Embodiment one:
Adding sulfuric acid in granulous aluminium ore slag, perhaps add hydrochloric acid again, is to add water at 0.5～2 o'clock to pH value, and stirring makes.
Embodiment two:
In clay, add in the acid such as sulfuric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid, silicic acid a kind of or some kinds be to add water at 0.5～2 o'clock to pH value, under normal temperature and pressure or High Temperature High Pressure, stir and make.
Embodiment three:
In the granulous pyrite slag, mix weight ratio and be 1: 1 coal ash, add some kinds of acid to pH values and be at 0.5～2 o'clock and add the hot water acidifying and make.
Embodiment four:
Is weight ratio that 1: 0.8～1: 0.6～1 pyrite slag, wilkinite, kaolin (or zeolite) raw material grind into the following particle of 20 orders, add a kind of or some kinds sour be to add water at 0.5～2 o'clock to pH value, under normal temperature and pressure or High Temperature High Pressure, react and make.
Embodiment five:
Is weight ratio that 1: 1.3 aluminium ore slag, bentonite material grinds into the following particle of 20 orders, add a kind of or some kinds sour be to add water at 0.5～2 o'clock to pH value, acidifying makes under normal temperature and pressure or High Temperature High Pressure.
Embodiment six:
In coal ash, add a kind of or some kinds sour be to add water at 0.5～2 o'clock to PH, under normal temperature and pressure or High Temperature High Pressure, make.
Embodiment seven:
Is weight ratio that 1: 0.8～1: 0.8～1 pyrite slag, coal ash (or broken brick and tile), bentonite material grind into the following particle of 20 orders, add a kind of or some kinds sour be to add water at 1.8 o'clock to pH value, acidifying at normal temperatures and pressures makes.
Embodiment eight:
Tile block is pulverized, add a kind of or some kinds of acid add the water reaction during to pH value 1 and make.
Embodiment nine:
Mix a certain amount of granular wilkinite, kaolin (or zeolite) in clay, add a kind of or some kinds of acid to pH values are to add water at 1 o'clock, acidifying makes under normal temperature and pressure or High Temperature High Pressure.
Undoubtedly, the raw material that is adopted among the above embodiment all contains aluminium, iron and other metals and compound thereof, mainly contains aluminium in the aluminium ore slag, and contains iron and other metals, mainly contains iron in the pyrite slag, and contains other metals; Contain iron, aluminium and other metals in the coal ash equally; Generate multiple metal-salt after acidifying, because aluminium salt and molysite all belong to strong electrolyte, the hydrolysis reaction that takes place soluble in water produces Fe
3+, Al
3+Ion, Fe
3+, Al
3+Ion all is good binding substances organizer, can form binding substances with a lot of ligands, has very strong coacervation; Also contain iron, the aluminium coupled ion of the macromolecule of some poly-hydroxy, multinuclear complexing body in solution, the hydrolysate of its same iron, aluminium salt equally has good coacervation; Also contain other metal-salts, can be by the low price ion exchange in the water body, produce high valence ion, reduce or eliminated colloidal solid
Current potential is in micelle and takes off steady state, easily coalescent, has strengthened the floculation of aluminium, molysite; Also contain the microvoid structure that differs in the aperture, strengthen and quickened absorption, coacervation, precipitate and separate process.Owing to contain aluminium, molysite simultaneously, the coacervation scope is big, and purifying water effect obviously improves; Owing to adopted some kinds of acid to react, make it contain the multiple same metal salt of some kinds of acid groups, further enlarged the coacervation scope, purifying water effect significantly improves.Obviously, purifying water effect of the present invention is splendid, but the direct purification papermaking wastewater, and the clearance of CODcr can reach more than 97%.
