Description
Vynález sa týká spdsobu zníženia flokulačného účinku zbytkového flokulantu anionického charakteru vo vratnej vodě, získanej pri odvodňovaní minérálnych a uhoíhýoh rmutov přidáním enioniokého flokulantu.The invention relates to a method of reducing the flocculation effect of residual anionic flocculant in the return water obtained by dehydrating mashes and coal mashes by adding an enionic flocculant.
Doposial? sa flokulačný účinok zbytkového flokulantu anioniokého charakteru vo vratnej vodě znižuje tak, že časť vratnej vody sa vypúšlfa do veřejného toku a nahradzuje sa čistou vodou.So far? the flocculation effect of the residual anionic flocculant in the return water is reduced so that part of the return water is discharged into the public stream and replaced with pure water.
Nevýhodou tohoto spůsobu je ve&cá spotřeba čistej vody a nabohacóvanieveřejného toku organickým flokulantom.The disadvantage of this method is the large consumption of pure water and the enrichment of the public stream by the organic flocculant.
Uvedený nedostatok je podlfa vynálezu odstránehý znížením flokulačného účinku zbytkového flokulantu anioniokého charakteru vo vratnej vodě, získanej pri odvodňovaní minérálnych a uhoínýoh rmutov přidáním anionického flokulantu, ktorého podstata spočívá v tom, že vratná voda, obsahujúca zbytkový flokulant anionického charakteru sa cedí oez vrstvu zrnitých látok so sorhčnými vlastnosíami, ktoré sa po naadsorbování zbytkového flokulantu na ioh povrchu vymenia za čisté zrnité látky rovnakýoh vlastností.This problem is overcome by reducing the flocculation effect of the residual anionic flocculant in the return water obtained by dehydration of mineral and coal mashes by the addition of anionic flocculant, characterized in that the return water containing the residual anionic flocculant is diluted with the anesic layer. sorption properties which, after adsorption of residual flocculant on the surface of the surface, are replaced by pure granular substances of the same properties.
Vratná voda, obsahujúoa zbytkový flokulant anionického charakteru, sa cedí cez vrstvu dolomitu zrnitostnej triedy 0,4 mm až 1,4 mm, alebo vrstvu čierhóuholného koksu zrnitostnej triedy 1,4 mm až 3 mm.The return water, containing the residual anionic flocculant, is passed through a layer of dolomite of grain size of 0.4 mm to 1.4 mm, or a layer of black-coal coke of a grain size of 1.4 mm to 3 mm.

Znížením flokulačnáho účinku nezřeagováného zbytku.makromolekulověj flokulačnej látky obsahnutej to vodě pódia vynálezu sa dooieli, že ea voda míže spať použiť ako vratná, bez nárokov na spotřebu čerstvej vody, pričom nepdsobí zhorženie technologických ukazovateíov úpravy.By reducing the flocculation effect of the unreacted residue of the macromolecular flocculant contained in the water according to the invention, it has been found that ea can be used as a return, without the need for fresh water consumption, without causing deterioration of the treatment process indicators.
Příklad provedenia.Example of implementation.
Zníženie flokulačnáho účinku zbytkového flokulantu anioniokého charakteru Polyflok 90 AP, obaiahnutáho vo vratnéJ vodě, získanej odvodňováním bentonitováho rmutu s týmto flokulantom v množštve 3 g.m“^ rmutu, sa dosiahne oedením vratnej vody oez vrstvu dolomitu zrnitostnej triedy 0,4 mm až 1,4 mm, alebo vrstvu čiernouhoínáho koksu zrnitostnej triedy 1,4 mm až 3 mm o výáke 1500 mm, vytvořenaj v nádobě tvaru valoa priemeru 800 mm, opatřenaJ otvárateíným dnom a kruhovými otvormi na odvádzanie preoedenej vody, priemeru «1 oReduction of the flocculation effect of residual anionic flocculant Polyflok 90 AP coated in return water, obtained by dewatering bentonite mash with this flocculant in an amount of 3 g / m 2, is achieved by diluting the return water over a layer of dolomite of grain size 0.4 mm to 1.4 mm or a layer of black-coke of a grain size class of 1,4 mm to 3 mm with a height of 1500 mm, formed in a 800 mm cylindrical vessel, provided with an openable bottom and circular openings for discharging diluted water of 1 mm diameter.
0,3 mm. Výměna dolomitu alebo čiernouhoináho koksu sa urobí po preoedení 5 mJ až 10 nr vratnéj vody.0.3 mm. Exchange čiernouhoináho dolomite or coke is made of preoedení 5 m to 10 J No return water.
