Polyaluminium chloride yog ib cov khoom siv lim dej tshiab, inorganic polymer coagulant. Thaum siv PAC, ntau cov neeg siv tsis muaj qhov zoo nkag siab txog qhov ntau npaum li cas, uas ua rau qhov tsis ua tiav ntawm kev kho dej dej pheeb. Yog li yuav ua li cas peb tuaj yeem ntxiv polyaluminum chloride rau kev kho dej phwj tuaj? Tam sim no peb yuav qhia koj yog tias koj tsis siv ntau dhau, thiab koj tuaj yeem ua tiav txoj kev kho dej phwj dej zoo tshaj plaws.
Cov qauv tshwj xeeb tau muab faib ua plaub lub ntsiab lus hauv qab no:

Rau 3% daws: hnyav Pac3G, muab tso rau hauv ib lub tog raj kheej xyoo 200ml ntsuas, ntxiv rau ntawm cov dej huv, ntxiv rau cov dej kom huv rau lub hli 100ml, thiab co nws zoo.
2. Qhov ntau lawm yog raws cov khoom: huv si dej {{1, ua ntej sib tov thiab yaj ua ntej, thiab tom qab ntawd ntxiv dej rau dilute rau 2 ~ 3% (w / v) tov. Tsawg dua 1% ntawm kev daws teeb meem yooj yim rau hydrolyze, uas yuav txo cov nyhuv siv, thiab siab dhau lub tswv yim yuav ua rau khib nyiab.
3. Ntxiv cov tshuaj raws li qhov zoo tshaj plaws muab tau. Them sai sai rau kev soj ntsuam thiab kev hloov kho thaum lub sijhawm ua haujlwm. Yog tias muaj ob peb alum blooms (flocs) nyob rau hauv lub tenimation tank thiab cov chaw muaj dej loj, tom qab ntawd cov tshuaj tsawg heev; Yog tias cov dej nag thaum sawv daws tau loj thiab upturned, thiab cov seem tsis muaj zog yog qhov siab, cov tshuaj ntau heev. Nws yuav tsum tau hloov kho kom zoo.
4. Kev kho vaj tse yuav tsum yog antiseptic. Cov khoom no tsim nyog rau txhua qhov chaw dej kho.
