Kev xaiv thiab kev hloov pauv ntawm flocculants

Muaj ntau ntau hom flocculants, uas tuaj yeem muab faib ua ob pawg, ib qho yog inorganic flocculants thiab lwm yam yog cov organic flocculants.

(1) Inorganic flocculants: suav nrog ob hom hlau ntsev, hlau ntsev thiab txhuas ntsev, nrog rau inorganic polymer flocculants xws lipolyaluminium chloride. Cov khoom siv feem ntau yog: ferric chloride, ferrous sulfate, ferric sulfate, aluminium sulfate (alum), yooj yim aluminium chloride, thiab lwm yam.

(2) Organic flocculants: feem ntau yog cov khoom siv polymer xws li polyacrylamide. Vim hais tias polymer flocculants muaj qhov zoo ntawm: me me npaum li cas, ceev sedimentation tus nqi, siab floc zog, thiab muaj peev xwm mus nce pom ceev, nws cov nyhuv flocculation yog ob peb mus rau kaum ob lub sij hawm ntau dua li cov tsoos inorganic flocculants, yog li nws yog tam sim no dav siv. hauv cov dej num kho dej.

Polymer flocculant - polyacrylamide

Lub ntsiab raw khoom ntawmpolyacrylamide (PAM luv luv)yog acrylonitrile. Nws yog tov nrog dej nyob rau hauv ib qho kev faib ua feem thiab tau los ntawm hydration, purification, polymerization, ziab thiab lwm yam txheej txheem.

Cov lus xaus hauv qab no tuaj yeem kos los ntawm kev sim ua dhau los:

(1) Anionic PAM yog tsim rau inorganic suspended teeb meem nrog siab concentration thiab zoo nqi, nrog rau cov ntxhib suspended hais (0.01 ~ 1mm), thiab nruab nrab los yog alkaline pH nqi.

(2) Cationic PAM yog tsim rau cov teeb meem raug tshem tawm nrog cov nqi tsis zoo thiab muaj cov organic teeb meem.

(3) Nonionic PAM yog tsim rau kev sib cais ntawm cov teeb meem tshem tawm hauv cov organic thiab inorganic sib xyaw, thiab cov tshuaj yog acidic lossis nruab nrab.

Kev npaj Flocculant

Lub flocculant tuaj yeem yog theem khoom lossis theem siab concentration kua. Yog hais tias flocculant no ncaj qha ntxiv rau qhov ncua kev kawm ntawv, vim nws qhov siab ceev thiab qis diffusion tus nqi, lub flocculant tsis tuaj yeem tawg tau zoo nyob rau hauv kev ncua, ua rau ib feem ntawm cov flocculant tsis tuaj yeem ua lub luag haujlwm flocculation, uas ua rau khib nyiab ntawm flocculant. . Yog li ntawd, ib qho kev sib tov sib xyaw yog xav tau los ua kom cov flocculant thiab cov dej tsim nyog kom ncav cuag ib qho concentration, feem ntau tsis ntau tshaj 4 ~ 5g / L, thiab qee zaum tsawg dua qhov nqi no. Tom qab stirring tusyees, nws yuav siv tau. Lub sij hawm stirring yog li 1 ~ 2 teev.

Tom qab cov polymer flocculant tau npaj, nws lub sijhawm siv tau yog 2 ~ 3d. Thaum cov tshuaj ua mis nyuj dawb, nws txhais tau hais tias cov tshuaj tau deteriorated thiab tas sij hawm, thiab nws yuav tsum tau nres tam sim ntawd.

Cov pab pawg amide ntawm polyacrylamide tsim los ntawm Yixing Cleanwater Chemicals Co., Ltd. tuaj yeem muaj kev sib raug zoo nrog ntau yam tshuaj, adsorb thiab tsim hydrogen bonds. Qhov hnyav molecular hnyav polyacrylamide tsim txuas txuas ntawm adsorbed ions, tsim flocs, thiab ua kom cov sedimentation ntawm cov khoom, yog li ua tiav lub hom phiaj ntawm cov khoom sib cais. Muaj anionic, cationic thiab non-ionic hom. Nyob rau tib lub sijhawm, cov neeg siv khoom kuj tuaj yeem kho cov khoom ntawm cov khoom sib txawv
