Vynález sa týká flokulantu na báze solí kovov hliníka, železa, horčíka a vápnika s prídavkom koloidného oxidu křemičitého vo founě kysláho roztoku připraveného extrakciou prírodných aluminosilikétov kyselinami.The invention relates to a flocculant based on aluminum, iron, magnesium and calcium metal salts with the addition of colloidal silicon dioxide in an acid solution solution prepared by acid extraction of natural aluminosilicates.
Je známe, Se vodorozpustné eoli kovov ako napr. chlorid hlinitý, chlorid železitý, síran hlinitý, hlinitan sodný sa používajú pre účely flokulácie a zréžania. Obdobné sú známe postupy flokulácie v kyslo reagujúcich soloch kyseliny kremičitej.It is known that water-soluble metal salts such as e.g. aluminum chloride, ferric chloride, aluminum sulfate, sodium aluminate are used for flocculation and slitting purposes. Similar processes are known to flocculate in acid-reacting silicic acid salts.
Teraz bolo zistené, Se na čistenie odpadných vod je vhodný flokulant na báze Selezitých, hlinitých, horečnatých a vápenatých solí vo formě kysláho roztoku z aktivácie prírodných aluminosilikétov, najma bentonitov, kyselinami vyznačujúci sa tým, že obsahuje katióny kovov hliníka, železa, horčíka a vápnika o hmotnostnom pomere voči.celkovému obsa hu katiónov vo flokulante a hliníka od 0,15 do 0,65, u železa od 0,1 do 0,25, u horčíka od 0,1 do 0,2 a u vápnika od 0,1 do 0,5, pričom flokulant obsahuje v sušině 0,01 až 5 % koloidného oxidu křemičitého.It has now been found that for the purification of sewage, a flocculant based on selesite, aluminum, magnesium and calcium salts in the form of an acid solution from the activation of natural aluminosilicates, in particular bentonites, acids, characterized in that it contains aluminum, iron, magnesium and calcium cations having a weight ratio to total cations in flocculant and aluminum from 0.15 to 0.65, iron from 0.1 to 0.25, magnesium from 0.1 to 0.2 and calcium from 0.1 to 0.2 0.5, wherein the flocculant contains from 0.01 to 5% colloidal silica in dry matter.
Tieto kyslé roztoky solí po separécii tuhých častíc aluainosilikátov je možné použit pri flokulácii odpadových vod z priemyselnej a živočišnéj výroby ako aj pri zrážanl emulzií olejovitých látok, neutralizáeii alkalicky reagujúcich odpadových vod, zahušťovaní kalov a ako přídavné prostriedky na zlepSenie flotécie.These acidic salt solutions, after separation of the solid particles of aluminosilicates, can be used in flocculation of waste water from industrial and animal production as well as in precipitation of oily emulsions, neutralization of alkaline reacting waste water, sludge thickening and as additional means to improve flotation.
Ďalej uvedené příklady bližSie ilustrujú ale neobmedzujú predmet vynálezu.The following examples illustrate but do not limit the invention.
Příklad 1Example 1
Do jedného litra odpadovej vody s CHSK=*7300 mg/1 a pH«12,4 zo závodu na výrobu farbív a lakov sa přidá 250 ml flokulantu vo formě kysláho roztoku z pomerom jednotlivých ke tiónov kovov voči celkovému obsahu vyextrahovaných kovov u Al=»0,4j Fe«0,16j Mg=0,1 a Ca=»0,26, a s obsahom 0,1 % hm. koloidného SiOg v sušině extraktu. Po zmiešaní male odpadni voda pH»6,5 a OHSK=1700 mg/1.To one liter of waste water with COD = * 7300 mg / l and a pH of 12.4 from the dye and varnish factory, 250 ml of flocculant are added in the form of an acidic solution in proportions of metal to metal ions relative to the total metal content 0.4j Fe 0,1 0.16j Mg = 0.1 and Ca = 0,2 0.26, and containing 0.1% wt. colloidal SiOg in the extract dry matter. After mixing, the waste water pH > 6.5 and OHSK = 1700 mg / L are mixed.

Po vyčírení mala odpadová voda CHSK*8 000 mg/1.Waste water from pig breeding pigs with COD = 20 20,000 ag / l was treated with a floc of lants of the same composition as in Example 1 in a 9: 1 volume ratio. After clarification, the COD wastewater * was 8,000 mg / l.
