Polydadmac, nws lub npe tag nrho yog polydimetlylentylaslamium chloride, yog cationic dej-soluble dej polymer uas tau siv dav hauv kev kho cov dej. Vim tias nws cov cim tshwj xeeb lub zog them nqi thiab cov dej ua haujlwm siab, Polydarmac yog qhov zoo tshem tawm cov xim, xim thiab lwm yam tsis txaus hauv dej. Txawm li cas los xij, hauv cov ntawv thov siv, nws feem ntau siv ua aFlocculantua ke nrog lwm co coagulants los kho cov dej phwj.
Cov yam ntxwv thiab kev siv hluav ntawm kev ua ntawm Polydadmac
Polydadmac Cov Neeg Tawm Tsam Ceev Xwm thiab Aggregates tsis zoo them colloidal hais thiab tshem tawm cov dej hauv dej vim nws lub cationic them ntau. Nws cov kev ua tshuab ntawm kev nqis tes ua yog feem ntau yog raws cov khoom siv hluav taws xob txuas ntxiv, uas lawv tuaj yeem raug tshem tawm tau zoo lossis cov txheej txheem kev lim dej.
Flocculation mechanism ntawm Polydadmac
Flocculation yog ib qho ntawm cov kauj ruam hauv cov txheej txheem kev sib cais. Nws hais txog cov txheej txheem uas lub
"Me alum paj" tsim thaum lub sij hawm txheej txheem txheej txheem flocs nrog cov khoom loj los ntawm kev kos duab, cov hluav taws xob nruab nrab, puridging thiab new-capture.
Nyob rau hauv kev kho dej kev kho, kev tshaj tawm hluav taws xob yog classfied, thaum tus neeg tawg thiab net-capture raug faib ua flocculation. Cov tshuaj sib tov tau hu ua coagulants thiab flocculanticive feem.
Nws yog feem ntau ntseeg tias Polydadmac muaj peb txheej txheem ntawm kev nqis tes ua: adsorption, nruab nrab ntawm nruab nrab thiab bridging. Thawj ob yog cov tseem ceeb. Tias yog vim li cas polydadmac tau cais ua coagulants. Txawm li cas los xij, feem ntau cov neeg muaj kev cuam tshuam colagulation thiab flocculation zoo li qub txheej txheem, yog li Polydadmac tseem hu ua Flocculant.
Hauv cov txheej txheem kev kho dej, Polydadmac yog siv los ua cov flocculant los txhim kho cov dej ua tau zoo. Tshwj xeeb, Cationic Qaus liv Dub Pab Pawg ntawm Polydadmac tau tsim cov khoom siv hluav taws xob lossis kev sib cais hauv cov pa roj av loj dua thiab sib txuas. Cov flocs no tau tshuaj ntsuam tawm thaum lub sijhawm ua kom tiav lossis txheej txheem kev lim dej kom huv.
Qhov Zoo ntawm Polydadmac
Piv nrog cov tsoos flocculants (Alum, PAC, thiab lwm yam), Polydarmac muaj qhov tseem ceeb hauv qab no:
Kev siv tau: Polydadmac tuaj yeem tshem cov impurities sai sai hauv dej thiab txhim kho cov dej zoo.
Ib qho yooj yim ua haujlwm: nws siv yog yooj yim, tsuas yog ntxiv nws nyob rau hauv cov xwm txheej tsim nyog.
Kev Ncaj Ncees: Polydadmac muaj kev ruaj khov zoo thiab tsis tawg yooj yim zoo li polyacrylamide.
Cov txiaj ntsig flocculation muaj zog: Cationic Qaus liv Almonium ntsev pab pawg muab lub peev xwm, yog li zoo kho ntau yam dej zoo;
Cov ntsev zoo tsis kam, kua qaub thiab alkali tsis haum: thiab nws tseem ruaj khov flocculation kev ua tau zoo nyob rau hauv high salinity, acidic lossis alkaline cov xwm txheej;
Tus nqi qis: Polydadmac tau muaj cov flocculation high high flocculation efficiency thiab muaj ntau yam, uas tuaj yeem txo cov nqi dej nyab.
Tsawg sludge: polydadmac tsim tawm tsawg dua inorganic co coavulants thiab flocculants thiab txuag cov nqi tom qab ua.
Polydadmac noj thiab ceev faj
Thaum siv polydadmac, kev ua haujlwm cov txheej txheem yuav tsum ua kom nruj ua raws li kom ntseeg tau cov txiaj ntsig zoo thiab tsis txhob muaj kev cuam tshuam dab tsi. Feem ntau, tom qab ntxiv flocculants xws li polyaluminium chloride, Polydadmac ntxiv kom ua tiav cov txiaj ntsig zoo tshaj plaws. Tsis tas li ntawd, cov nqi yuav tsum tau hloov kho kom zoo raws li dej ua kom zoo thiab kho kom zoo. Qhov haum tshuaj yuav txiav txim siab los ntawm cov hlau kev kuaj.
Tag nrho cov hauv txhua qhov,PolydadmacUa si lub luag haujlwm tseem ceeb hauv kev kho cov dej. Ib qho kev nkag siab tob txog nws cov khoom thiab cov ntawv thov yuav pab siv tau ntau cov khoom lag luam zoo thiab tiv thaiv ib puag ncig.
