Dab tsi yog cov cationic flocculants?

Kev kho cov dej yog qhov tseem ceeb ntawm kev tswj hwm ib puag ncig, kom ntseeg tau tias dej muaj kev nyab xeeb rau kev noj thiab siv. Ib qho ntawm cov ntsiab lus tseem ceeb hauv cov txheej txheem no yog kev siv cov tshuaj uas txhawb nqa cov ceg ntoo loj, lossis cov flocs, uas tuaj yeem tshem tawm cov dej yooj yim dua los ntawm dej. Ntawm ntau hom flocculants, cationic flocculants tshwj xeeb yog vim lawv txoj kev them nqi zoo, uas cuam tshuam nrog cov kev sib cuam tshuam tsis zoo nrog cov khoom siv tsis zoo. Tsab ntawv no tshawb nrhiav cov cationic flocculants siv nyob rau hauv kev kho dej thiab lawv cov ntawv thov.

Cationic Polyacrylamides(CPAM)

Cationic Polyacrylamides, yog nyob ntawm cov feem ntau dav siv flocculants hauv kev kho cov dej. Rau ntau tus neeg siv, CPAM yog lawv txoj kev xaiv zoo. Cov neeg polymers muaj cov acrylamide subrylamide, uas tuaj yeem ua kom haum kom suav nrog cov pab pawg cationic. Cov versatility ntawm cationic polyacrylamides cov lus dag nyob rau hauv lawv cov kho tau molecular hnyav thiab them nuj nqis ntom, tso cai rau kev kho cov kev siv rau cov ntaub ntawv tshwj xeeb. C-PAMS muaj txiaj ntsig zoo rau kev kho cov dej khib nyiab thiab sludge dewatering vim lawv lub siab flocculation effecticy thiab kuj muaj kev cia siab ntau.

Poly (dial allflasmonium chloride) (Polydadmac)

Polydadmac yog cov cationic flocculant paub rau nws cov nqi siab thiab ua haujlwm hauv cov txheej txheem dej. Cov txheej txheem polymer no tshwj xeeb tshaj plaws hauv kev ua yeeb yam thiab cov txheej txheem frocculation, ua rau nws xaiv nrov rau kev kho cov dej haus, dej khib nyiab, thiab effluents. Polydadmac ua haujlwm tau zoo nrog lwm tus flocculants thiab coagulants, txhim kho cov txheej txheem kev kho mob tag nrho los ntawm kev muab lub zog sib cav rau cov particle rau kev sib cav sib ceg thiab tshem tawm.

Polyamines(Pa)

Polyamines muaj lwm qeb ntawm cationic flocculants feem ntau siv nyob rau hauv kev kho dej. Cov tebchaw no, uas suav nrog poly (dimethyloramine-co-epichlorohdrin) thiab cov qauv zoo sib xws, ua rau lawv muaj zog ntawm nruab nrab tsis zoo siv. Polyamines tau muaj txiaj ntsig tshwj xeeb hauv kev qhia ntawm cov dej nyoos, tshem tawm cov organic teeb meem, thiab kev kho mob ntawm ntau yam kev muaj effluents. Lawv lub peev xwm los tsim cov nthwv dej ntws nrawm hauv lub sijhawm nrawm dua thiab txhim kho cov dej ntshiab.

Cov ntawv thov thiab cov txiaj ntsig

Cationic flocculants ua si tseem ceeb lub luag haujlwm nyob rau hauv ntau cov kev siv dej ntau, los ntawm cov hauv nroog dej kom huv thiab haus dej kom huv. Lawv thawj qhov txiaj ntsig nyob hauv lawv lub peev xwm los ua kom muaj kev cuam tshuam zoo tsis zoo them cov lus tsis zoo, ua kom nrawm dua thiab txuag floc. Qhov no ua rau muaj kev pom meej meej, txo cov turbidity, thiab txhim kho cov dej ua haujlwm tag nrho. Ib qho ntxiv, cationic flocculants feem ntau siv nyob rau hauv kev ua ke nrog lwm cov tshuaj kho, kom ua kom zoo rau cov txheej txheem kev kho mob thiab ua tiav cov qauv dej zoo.

Kev siv ntawm cationic flocculants yog qhov tseem ceeb rau cov txheej txheem kho dej kom zoo thiab txhim khu kev qha thiab tshem tawm cov ntsiab lus particle thiab tshem tawm. Polyacrylamides, Polyamines, Polydadmac sawv cev rau qee qhov ntawm feem ntau thiab zoo cationic flocculus muaj niaj hnub no. Lawv cov versatility, kev ua tau zoo, thiab kev yoog tau ua rau lawv muaj cov cuab yeej tseem ceeb hauv kev ua kom muaj dej huv thiab nyab xeeb rau ntau yam dej.

Ntawm chav kawm, kev xaiv flocculant kuj nyob ntawm tus neeg siv kev siv, cov khoom muaj pes tsawg leeg, ib puag ncig, thiab lwm yam Tswv yim yuav tsum tau ua raws.
