Water treatment facilities, comprises water treatment agent and the container in order to load water treatment agent, and described water treatment agent contains above-mentioned a kind of purification of water quality absorbent charcoal composite material.
Active carbon is the outward appearance that a kind of carbonaceous material is made is black, and internal pore structure is flourishing, and specific area is large, a class carbon materials of high adsorption capacity, is a kind of conventional adsorbent, catalyst or catalyst carrier.Active carbon has to be used widely
On the way, in order to improve the application quality of active carbon, need the active carbon to adopting Physical to produce to carry out acidification, the present invention selects the active carbon after pulverizing, grain fineness≤0.5 millimeter of active carbon.
Concave-convex clay rod has unique layer chain structure feature, and crystal is needle-like, threadiness or fiber collection shape.Recessed
Convex excellent stone clay has unique dispersion, high temperature resistant, anti-good colloidal nature and the higher adsorption capacity such as saline and alkaline, and there is certain plasticity and cohesive force, the present invention selects the Concave-convex clay rod after pulverizing, grain fineness≤5 millimeter of Concave-convex clay rod.
Magnesia has the general character of basic anhydride, belongs to Binder Materials, can improve the colloidal property of Concave-convex clay rod.
Quick dissolved sodium silicate is white powder material, can rapid solution in water, have that cohesive force is strong, intensity is higher, acid resistance, good heat resistance, the feature of alkali resistance and poor water resistance.
Polyethenol series white solid, external form divide cotton-shaped, graininess, Powdered three kinds; Nonpoisonous and tasteless, graininess can be
Dissolve in 80--90 DEG C of water, pulverous other powders pre-dispersed after can dissolve at normal temperatures.There is good viscosity, polymerism, caking property and water-retaining property.
Medical stone: (1) absorption affinity is strong: so-called absorption is the whole solvation of solid with porous, huge surface area, and reaction that is chemical, physics occurs.Medical stone, is particularly drawn out the pus to skin disease as Chinese medicine, and effect is fine.Medical stone is porous, and adsorption capacity is very strong, because of its main component be silica, aluminium oxide is considered from this point, is easy understand.In the electron micrograph of the medical stone attritive powder introduced above, being confirmed to be spongy porous, is its maximum reason.That is, because of porous, so surface is just very large, due to the weathering of feldspar part, becomes kaolin shape etc., therefore remains very strong suction-operated, exchange interaction.
(2) medical stone is to water purification effect: medical stone is a kind of neutral alkali half igneous rock, close to volcanic rock.The natural mineral matter comprised in medical stone is easy to discharge in apertures countless from medical stone and discharges oxygen.Purify waste water with other noxious material by absorbing bleaching powder.The mineral matters such as the calcium given out in medical stone, iron, sodium can improve drinking water.
Compared with prior art, the invention has the beneficial effects as follows:
Souring activity charcoal, quick dissolved sodium silicate, nickel nitrate, polyvinyl alcohol, chitin, medical stone and butyl titanate are after the techniques such as ultrasonic, calcining, form constitutionally stable composite, have that adsorption capacity is high, heavy metal absorption be stable, the advantage of non-secondary pollution, in composite of the present invention, nickel, titanium and active carbon, medical stone have high bond strength, can prevent nickel, titanium from coming off from active carbon, medical stone, cause the secondary pollution to water.Wherein, the active carbon after acidifying has the high feature of good adsorptivity, thixotropy, heat endurance, plasticity, caking property and dry compression, improves effects of purification quality.
