Muaj ntau hom flocculants, uas tuaj yeem faib ua ob pawg, ib qho yog inorganic flocculants thiab lwm yam yog cov organic flocculants.
(1) Inorganic flocculants: suav nrog ob hom hlau hlau, hlau ntsev nrog cov ntsev txhuas, ntxiv rau cov kua ntses polymer polymulants xws liPolyaluminium chlorideCov. Cov khoom siv feem ntau yog: Ferric chloride, ferric sulfate, ferric sulfate, Alum), pib chloride, thiab lwm yam.
(2) organic flocculants: mas cov tshuaj polymer xws li polyacrylamide. Vim tias polymer flocculants muaj qhov zoo ntawm: tsawg tshuaj noj, kev muaj peev xwm nce kev ua kom muaj zog, thiab muaj peev xwm nce kev lim hiam ntau dua li ntawm cov tsoos inorganic flocculants, yog li nws tau siv dav Hauv kev kho dej dej.

Polymer Flocculant - polyacrylamide
Cov khoom siv tseem ceeb ntawmPolyacrylamide (Pam rau luv luv)yog acrylonitrile. Nws yog tov nrog dej nyob rau hauv ib qho kev faib ua feem thiab tau los ntawm kev co dej, huv huv, polymerization, kom qhuav thiab lwm yam txheej txheem.
Cov lus xaus nram qab no tuaj yeem kos los ntawm kev sim yav dhau los:
(1) Anionic Pam yog haum rau inorganic txwv tsis pub muaj teeb meem thiab zoo rau kev them nqi (0.01 ~ 1 hli), thiab nruab nrab ntawm tus nqi.
(2) Cationic Pam yog qhov haum rau kev ncua cov teeb meem nrog kev them nqi tsis zoo thiab muaj cov organic.
(3) Cov Nonulic Pam yog tsim nyog rau kev sib cais ntawm cov teeb meem organic thiab inorganic rau cov organic thiab kev daws teeb meem yog acidic lossis nruab nrab
Flocculant npaj
Cov flocculant tuaj yeem yog theem khoom lossis siab siab theem. Yog tias cov flocculant no tau ntxiv rau qhov kev ncua, vim nws qhov kev sib txawv siab thiab qis tsis tuaj yeem ua rau cov flocculant tsis muaj peev xwm ua si flocculation lub luag haujlwm, ua rau cov khib nyiab ntawm flocculant Cov. Yog li ntawd, cov tov khoom tsis dhau yuav tsum tau siv cov nplaim dej uas tsim nyog, feem ntau tsis ntau tshaj 4 ~ 5g / u, thiab qee zaum tsawg dua tus nqi no. Tom qab nplawm tusyees, nws tuaj yeem siv. Lub sijhawm stirring yog li 1 ~ 2h.
Tom qab cov polymer flocculant yog npaj, nws lub sijhawm siv tau yog 2 ~ 3D. Thaum cov kev daws teeb meem ua milky dawb, nws txhais tau tias kev daws teeb meem tsis zoo thiab tas sij hawm, thiab nws yuav tsum nres tam sim ntawd.
Cov pab pawg ntawm polyacrylamide tsim los ntawm yixing huv huv tshuaj Co., Ltd. tuaj yeem affinity nrog ntau cov tshuaj, adsorb thiab tsim hydrogen bonds. Kuj yog cov molecular hnyav polyacrylamide txuas hniav sib txuas ntawm adsorbed ions, tsim cov flocs, yog li ua tiav lub hom phiaj kawg ntawm cov kua-kua sib cais. Muaj anionic, cationic thiab tsis-ionic hom. Nyob rau tib lub sijhawm, cov neeg siv khoom tuaj yeem hloov kho cov khoom lag luam sib txawv
