Polydimethyl diallyl ammonium chloride (PDMDAAC) yog ib yam khoom siv kho dej uas pheej yig thiab siv tau ntau yam, uas hloov tau ntau yam tshuaj ib txwm muaj hauv ntau qhov xwm txheej, muab cov txiaj ntsig tseem ceeb xws li kev zoo dua, txo nqi, thiab ua haujlwm tau zoo dua. Nws tuaj yeem hloov tau cov tshuaj uas tsis muaj xim xws li polyferric sulfate thiab polyaluminum chloride, nrog rau cov pa roj carbon activated, nrog rau tsuas yog 1/3 ntawm cov tshuaj ib txwm muaj, ua rau muaj kev tshem xim ntau dua thiab txo cov sludge ib nrab. Nws tuaj yeem kho tau ntau hom recalcitrant dye wastewater, txo cov nqi pov tseg sludge.
Tib lub sijhawm, nws tuaj yeem hloov cov cationic PAM ib txwm muaj, muab cov nqi qis dua, yaj tau zoo dua, thiab ua haujlwm yooj yim dua ntawm tib lub cationicity. Kev siv ua ke tuaj yeem txo cov nqi ntawm tus neeg sawv cev los ntawm 30%, thiab nws tuaj yeem hloov pauv tag nrho cov xwm txheej dewatering sludge ib txwm muaj. Ntxiv mus, nws tuaj yeem hloov cov tshuaj coagulants ntsev txhuas xws li alum thiab polyaluminum sulfate, tsis cuam tshuam los ntawm qhov kub ntawm dej, tsim cov flocs ntom ntom, sai-settling, tshem tawm cov teeb meem aluminium residue, thiab ruaj khov qhov zoo ntawm effluent.
Nws kuj tseem tuaj yeem ua ke nrog hmoov hlau los hloov cov kua qaub sludge conditioning lime, yam tsis nce sludge ntim, tsis muaj impurities, thiab ua kom yooj yim rau kev kho mob downstream. Txawm hais tias cov sludge nyuaj xav tau cov neeg sawv cev sib xyaw, qhov kev siv nyiaj tag nrho zoo dua li cov neeg sawv cev ib txwm muaj. Hauv qhov huab cua tam sim no ntawm kev tswj hwm tus nqi nruj thiab kev nrhiav cov dej khib nyiab ruaj khov, PDMDAAC, nrog nws ntau qhov zoo ntawm cov tshuaj tsawg, kev tsim sludge tsawg, cov teebmeem ruaj khov, thiab yooj yim ntawm kev ua haujlwm, tau dhau los ua qhov kev xaiv hloov kho dua tshiab rau cov chaw kho dej khib nyiab loj thiab dej los hloov cov neeg sawv cev ib txwm muaj, yooj yim ua tiav ob qho tib si kev kho dej zoo dua thiab txo cov nqi.
