Indima ye-calcium chloride ekuhlanzweni kwendle

Okokuqala, indlela yokwelapha indle ihlanganisa kakhulu ukwelashwa ngokomzimba kanye nokwelashwa ngamakhemikhali. Indlela engokoqobo ukusebenzisa izinto zokuhlunga ezahlukahlukene ezinobukhulu obuhlukene be-pore, ukusetshenziswa kwezindlela zokufaka noma zokuvimba, ukungcola emanzini akufakiwe, okubaluleke kakhulu endleleni yokufaka i-adsorption ukufutha nge-activated carbon, indlela yokuvimba iwukudlulisa amanzi ezintweni zokuhlunga, ukuze inani elikhulu lokungcola lingadluli, bese uthola amanzi ahlanzekile engeziwe. Ngaphezu kwalokho, indlela engokoqobo ihlanganisa nendlela yokukhipha imvula, okuwukuvumela ukungcola okunesilinganiso esincane kuntante ebusweni bamanzi ukuze kuphume izinhlanzi, noma ukungcola okunesilinganiso esikhulu kungene ngaphansi kobuso, bese kutholakele. Indlela yamakhemikhali ukusebenzisa izinhlobo ezahlukene zamakhemikhali ukuguqula ukungcola emanzini kube izinto ezingelona ingozi kangako emzimbeni womuntu, noma ukungcola kugxilile, indlela yokwelapha ngamakhemikhali kufanele isetshenziswe isikhathi eside ukwengeza i-alum emanzini, ngemva kokuqoqwa kokungcola emanzini, ivolumu iba nkulu, ungasebenzisa indlela yokuhlunga ukususa ukungcola.

I-calcium chloride, ikhemikhali evame ukusetshenziswa ekuhlanzweni kwendle, iyinhlanganisela engaphili engusawoti owakhiwe yi-chlorine ne-calcium, i-ionic halide ejwayelekile. Ama-chloride ions angabulala amagciwane emanzini, abulale amagciwane ayingozi, futhi anciphise ubuthi bamanzi. Ama-calcium ions angathatha indawo yama-cation ensimbi aqukethwe emanzini, ahlukanise futhi akhiphe ama-ion ensimbi anobuthi, futhi aqede ukumuncwa kwama-ion e-calcium, anomphumela omuhle wokubulala amagciwane kanye nokuhlanza.

Okulandelayo ukwethula indima ethile ye-calcium chloride ekuhlanzweni kwendle:

1. I-calcium chloride encibilikiswe emanzini ngemva kokuba i-ion ye-chloride ibe nomphumela wokubulala amagciwane.

2. Ama-ion e-calcium angathatha indawo yama-cation ensimbi emngcoleni, ikakhulukazi enkambisweni yokwelapha amanzi angcolile aqukethe ama-cation ensimbi. Ukuze kuncishiswe umonakalo wezinto ezinobuthi kakhulu zama-cation ensimbi engxenyeni ye-biochemical, i-calcium chloride isetshenziswa enkambisweni yangaphambi kokwelashwa ukususa lezi zinto ezinobuthi neziyingozi, ezidlala indima ebalulekile. Uma lesi sici sisetshenziswa engxenyeni yokungcola, ama-ion e-chloride adlala indima yokubulala amagciwane. Ama-ion e-calcium akha i-calcium hydroxide aqhuma futhi asuswa yimvula.

3. Ukungaguquguquki kwe-PH kanye nokulawulwa kwangaphambili kwenethiwekhi yamapayipi endle ane-asidi ukuze kwandiswe impilo yenethiwekhi yamapayipi.

Inqubo ethile yokusebenzisa: Ngemva kokuba amanzi angcolile eqoqwe ethangini elilawulayo, amanzi angcolile aphakanyiswa aye ethangini lokujiya ngepompo yokuphakamisa. Ithangi lokujiya lihlukaniswe izinqubo ezimbili zokuxuba kancane nokuxuba ngokushesha, okuyizigaba ezine zokusabela. Ethangini lokuxuba ngokushesha, i-sodium hydroxide ingezwa ephampini lokulinganisa ukuze kulungiswe i-PH yamanzi axubile ethangini ibe ngu-8, bese kuthi i-polyaluminum chloride encibilikayo emanzini kanye ne-calcium chloride kufakwe ngasikhathi sinye. Ngokufaka i-flocculant polyacrylamide ethangini lokuxuba kancane, izinhlayiya ze-calcium chloride ezakhiwe ziyajiyana ukuze zakhe i-floc enkulu ene-granular; Ngemva kokujiya, ukugeleza kokungcola kuya ethangini lokujiya, ngokusebenzisa ukuhlala kwemvelo ukuze kufezwe injongo yokuhlukaniswa koketshezi oluqinile, i-supernatant yagcwala engxenyeni engenhla yethangi lokujiya, bese igeleza iye ekujuleni kwesibili kokujiya. Ngemva kokwelashwa kwesibili kokujiya kanye nokwemvula, amanzi adlula ngesihlungi sesikhwama kanye nesihlungi sekhabhoni esisebenzayo aye echibini lokungazweli kwe-acid-base ohlangothini lomnikazi ngemuva kokudlula ekutholakaleni kwe-ion ye-fluoride online, bese kuba nenani le-pH elilungisiwe bese likhishwa. Amanzi angafaneleki akhishwa ethangini lokulungisa bese elashwa.
