Cov neeg uas muaj kev paub ntau hauv kev kho cov dej khib nyiab paub tiaspdadmacyog ib qho flocculant uas ruaj khov dua li cov neeg sawv cev ib txwm muaj. Feem ntau cov flocculants hauv khw muag khoom yog cov khoom siv uas yooj yim puas tsuaj los ntawm lub hnub ci, qhov kub qis, thiab cov kua qaub / alkalis, yooj yim sib sau ua ke thiab ua tsis zoo tom qab ib nrab lub hlis ntawm kev khaws cia, thiab yooj yim ua tsis zoo thaum muab tso rau hauv cov dej khib nyiab. Txawm li cas los xij, Polydimethyldiallyl ammonium chloride ua rau muaj kev kam rau siab heev. Nws cov txiaj ntsig tseem tsis cuam tshuam los ntawm qhov kub siab hauv lub caij ntuj sov lossis qhov kub khov hauv lub caij ntuj no, ua rau nws yog tus neeg sawv cev "ruaj khov" uas ntseeg tau hauv kev kho dej khib nyiab.
Qhov kev ruaj khov zoo tshaj plaws no yog los ntawm nws cov qauv molecular tshwj xeeb thiab muaj zog. Lub cev pob txha molecular ntawm tus neeg sawv cev no zoo li cov saw hlau hemp tuab, khi nruj, nrog rau cov qauv ruaj khov thiab yuav luag tsis muaj qhov tsis muaj zog. Hauv kev sib piv, cov flocculants ib txwm muaj feem ntau yog tsim los ntawm cov molecules me me uas yooj yim tawg thiab lwj hauv qhov kub siab, acidic, lossis alkaline ib puag ncig, poob tag nrho lawv cov nyhuv flocculation. Hauv kev sib piv, polydimethyldiallyl ammonium chloride qhia txog kev ruaj khov molecular saw hlau siab heev tom qab polymerization. Txawm tias nyob rau hauv lub sijhawm ntev raug rau qhov kub siab dej khib nyiab ib puag ncig, nws cov qauv molecular tseem nyob ruaj khov thiab ua haujlwm tau zoo. Qhov no yog qhov laj thawj tseem ceeb vim li cas nws tuaj yeem ua rau cov dej khib nyiab tsis huv sai sai thiab tsim cov flocs ntom txawm tias nyob rau hauv qhov chaw cia khoom qhib thiab qhov kub siab.
Cov pab pawg uas muaj cov khoom zoo sib xws ntawm nws cov saw hlau molecular ua haujlwm ua ib qho kev tiv thaiv ntuj, ua rau tus neeg sawv cev zoo sib xws rau cov dej zoo. Cov flocculants ib txwm tsis muaj kev tiv thaiv ntawm qhov chaw thiab yooj yim raug txheej los ntawm roj thiab cov khoom tsis huv hauv cov dej khib nyiab, poob lawv lub peev xwm adsorption. Txawm li cas los xij, cov pab pawg uas muaj cov khoom zoo ntawm tus neeg sawv cev no tsis yog tsuas yog ua lub hom phiaj adsorption rau cov khoom tsis huv me me, cov xim, thiab cov pa phem xwb tab sis kuj cais nws tawm ntawm kev cuam tshuam sab nraud xws li cov kua qaub, alkalis, lwm yam tshuaj lom neeg, thiab roj, tiv thaiv cov qauv molecular tseem ceeb ntawm kev puas tsuaj. Qhov no tso cai rau kev sib raug zoo ruaj khov nrog cov dej khib nyiab hauv kev lag luam los ntawm kev zas xim, luam ntawv, thiab kev lag luam tshuaj lom neeg, qhov twg pH hloov pauv tseem ceeb.
Hais txog kev khaws cia thiab kev thauj mus los, nws cov txiaj ntsig zoo dua li cov tshuaj zoo sib xws. Feem ntau cov hmoov flocculants yooj yim nqus dej noo thiab sib sau ua ke; txawm tias cov dej noo me ntsis thaum khaws cia yuav ua rau lawv puas tsuaj, ua tsis tau zoo, thiab tsis yaj. Polydimethyl diallyl ammonium chloride (PDMC) muaj kev ruaj khov zoo heev hauv cov kua thiab cov khoom khov, tsis muaj kev cuam tshuam tshuaj lom neeg tsis tsim nyog. Cov chaw kho dej khib nyiab tuaj yeem khaws cia rau hauv ntau yam tsis tas yuav tswj qhov kub thiab txias lossis dej noo. Nws tuaj yeem khaws cia rau hauv cov chaw khaws khoom kub thiab txias rau lub sijhawm ntev thiab tuaj yeem siv tau ib txwm txawm tias tom qab khov thiab yaj sab nraum zoov thaum lub caij ntuj no, tsis muaj teeb meem ntawm kev puas tsuaj lossis kev ua tsis tiav, txo qis tus nqi ntawm cov flocculant.
Ntxiv mus, nws cov khoom flocculated qhia tau tias muaj kev ruaj khov zoo heev. Cov flocculants ib txwm tsim cov flocs xoob thiab tawg yooj yim uas yooj yim tawg nrog cov dej ntws me ntsis, ua rau cov pa phem rov qab mus rau hauv dej thiab kev kho tsis ua haujlwm. Qhov sib piv, PDMC muaj lub peev xwm nqus tau zoo heev thiab kev sib koom ua ke, khi cov khoom tsis zoo thiab roj kom ua cov flocs tuab, ntom. Cov flocs no qhia tau tias muaj kev tiv thaiv zoo rau kev ntws dej, cov khoom zoo heev, thiab tsim cov sludge clumps uas tuaj yeem nias thiab pwm ncaj qha, zoo meej rau cov xwm txheej kho dej khib nyiab xws li cov teb roj. Nrog nws qhov kev ruaj khov tag nrho, tus neeg sawv cev no tau dhau los ua flocculant nyiam ntev hauv kev lag luam kho dej khib nyiab.
