Isimiso kanye nokusetshenziswa kwe-polyaluminium chloride (PAC) njenge-ejenti yokususa i-fluoride esebenza kahle kakhulu

1. Isimiso kanye nendlela yamakhemikhali yokususwa kwe-fluoride

I-Polyaluminum chloride (i-PAC) iyi-polymer compound engaphili, futhi ukususwa kwayo kwe-fluoride kwenziwa kakhulu ngezindlela ezimbili ezilandelayo:

Ukwelashwa ngamakhemikhali: Iphakethe incibilikiswe emanzini i-aluminium ion (Al³) ekhishwe, futhi ihlanganiswe ne-fluoride ion (F) ukuze yakhe i-hydrofluoric acid (HF) ephakathi, bese kwakheka imvula ye-aluminium fluoride (AlF ₃) enganyibiliki.

Umphumela we-co-precipitation: i-aluminium hydroxide colloid ekhiqizwa yi-PAC hydrolysis imboza i-free fluorine ion ngokusebenzisa i-surface adsorption kanye ne-mesh capture, bese ekugcineni iyisusa ngokuhlukaniswa kwe-solid-liquid.

2. Isicelo izimo nemiphumela

PhansiUkuhlanzwa Kwamanzi: Ezindaweni ezine-fluoride ephezulu (ukuhlushwa kwe-fluoride> 1.5 mg/L), i-PAC inganciphisa okuqukethwe kwe-fluoride kuye ezingeni likazwelonke lamanzi okuphuza (

Imfucuza yezimboniUkwelashwa Kwamanzi: ifanele amanzi angcolile amakhemikhali aqukethe i-fluorine (njenge-semiconductor, imboni yokuqopha ingilazi), ingahlanganiswa nezinye izinto zokususa i-fluoride (njenge-calcium salt) ukuze kuthuthukiswe ukusebenza kahle.

Uhlelo lokuphakelwa kwamanzi lukamasipala: njengendlela yokwelapha ngaphambi kokwelashwa noma yokwelapha ngokujulile, ukuqinisekisa ukuphepha kwamanzi okuphuza, ikakhulukazi ebusika basenyakatho, izinga lokushisa lamanzi kufanele lilawulwe ngo->20℃ ukuze kugcinwe ukusabela.

3. umongo inzuzo

Ukusebenza kahle okuphezulu: Uma kuqhathaniswa nosawoti we-aluminium wendabuko (njenge-aluminium sulfate), i-PAC inobuningi bokushaja okuphezulu kanye nesivinini sokugeleza okusheshayo, futhi ukusebenza kahle kokususwa kwe-fluorine kukhushulwa ngo-30% ngaphansi kwenani elifanayo lokwengeza.

Umnotho: izindleko zokwelashwa zingaphansi kuka-40% kuneze-alumina esebenzayo, i-reverse osmosis kanye nobunye ubuchwepheshe, futhi akudingeki imishini eyinkimbinkimbi.

Ukuzivumelanisa nezimo okubanzi: i-pH Uhlu olubanzi lokusetshenziswa (5.0-9.0), lungasusa ngokuhambisanayo ukungcoliswa, izinsimbi ezisindayo kanye nezinye izinto ezingcolisayo.

4. Sebenzisa amaphuzu ayisihluthulelo bese usebenzisa isiqondiso sokwenza ngcono

Engeza ukulawula: kunconywa ukunquma isilinganiso sokudla esifanele (ngokuvamile esingu-11-13kg / amathani ayinkulungwane amanzi) ngokuhlola i-beaker, futhi ukusetshenziswa ngokweqile kungaholela ekungcoleni kwe-aluminium ngokweqile.

Ukuthuthukisa izimo zokusabela: inani le-pH lihle kakhulu ku-6.5-7.6, kanti izinga lokushisa liphansi kuno-20℃ uma izinga lokushisa lenyuka.

Ukuthuthukiswa kwenqubo ehlanganisiwe: uhlelo lwe-CaF ₂ -AlF ₃ lokwelula kabili lungakhiwa uma luhlanganiswa nosawoti we-calcium (njenge-lime), futhi izinga lokususwa kwe-fluoride lingafinyelela ngaphezu kwama-95%.

5. Ezemvelo ukuvikelwa kanye nenani lezomnotho

Njengezinto ezibalulekile zokuvikela imvelo ezikhuthazwe esikhathini se-14th Five-Year Plan, i-PAC inciphisa ingozi ye-fluorosis futhi ikhuthaza ukuthuthukiswa kwemboni yokwelapha amanzi ngendlela engabizi kakhulu kanye nokusetshenziswa kwamandla okuphansi. Ukukhiqizwa kwayo okukhulu (umkhiqizo wasekhaya waminyaka yonke ongaphezu kwamathani ayi-180,000) kanye nokuthuthukiswa kobuchwepheshe (njengenqubo yezinto zokusetshenziswa kwe-aluminium hydroxide) kuqinisa kakhulu isikhundla esiphambili emakethe.

Ngokusebenzisa izindlela eziningi zokusebenza kanye nokusebenza kabanzi, i-polyaluminum chloride isibe ngesinye sezixazululo zokususa i-fluoride ezingabizi kakhulu nezisebenza kahle njengamanje. Ngokusetshenziswa kokuguqulwa kwe-nano kanye nobunye ubuchwepheshe esikhathini esizayo, ukusebenza kwayo kulindeleke ukuthi kufinyelele intuthuko enkulu.
