Ukwelashwa Kwamanzi: I-Quicklime noma I-Hydrated Lime - Yikuphi Okungcono?

Embusweni we ukuphathwa kwamanzi, ukukhetha phakathi ubhabha (i-calcium oxide, i-CaO) kanye umcako omuncu (i-calcium hydroxide, i-Ca(OH) ₂) yisinqumo esibucayi esingaba nomthelela omkhulu ekusebenzeni kahle, izindleko, kanye nomthelela wemvelo wenqubo yokwelapha. Zombili lezi zinto zidlala indima ebalulekile ekuhlanzweni kwamanzi okuhlukahlukene, kodwa izici zazo ezihlukile nokuziphatha kuzenza zifaneleke kakhulu izimo ezithile. Ake singene ekuqhathaniseni okuningiliziwe ukuze sinqume ukuthi iyiphi engaba yinketho engcono yezidingo zakho zokwelashwa kwamanzi.

Ukusabela Kwamakhemikhali kanye Nokulungiswa Kwe-pH

Uma i-quicklime yengezwa emanzini, ibhekana nokusabela kwe-exothermic, ikhiqize ukushisa ngokushesha futhi iguqule ibe umcako onamanzi: CaO + H₂O → Ca(OH)₂. Lokhu kusabela kunamandla amakhulu futhi kungakhuphula izinga lokushisa lamanzi kakhulu. Ngakolunye uhlangothi, i-hydrated lime isivele isesimweni se-hydroxide futhi incibilika emanzini ngaphandle kokukhululwa kokushisa okunobudlova.

Kokubili i-quicklime ne-hydrated lime iyasebenza ekulungiseni i-pH yamanzi. Angama-alkali aqinile angenza amanzi ane-asidi angabi namandla, awenze afanelekele ukwelashwa okwengeziwe noma aphephe ukuchithwa. Kodwa-ke, ngenxa yokuguqulwa okuqhubekayo kwe-quicklime ibe yi-hydrated lime emanzini, ingahlinzeka ngomthombo oqhubekayo we-alkalinity wokulungiswa kwe-pH. Lokhu kungaba wusizo ekwelapheni amanzi angcolile ezimboni ane-asidi kakhulu, lapho kudingeka khona ukwanda okukhulu nokuqhubekayo kwe-pH.

Ukukhipha Amagciwane kanye Nokususwa Kwe-Pathogen

Ukusabela kwe-Quicklime exothermic, kuhlanganiswe ne-pH ephezulu eyenzayo, kuyenza isibulala-magciwane esihle kakhulu. Ukushisa okukhiqizwa kungadala amaprotheni kanye nolwelwesi lwamangqamuzana amagciwane, kuyilapho i-alkalinity ephezulu ibulala amagciwane amaningi, amagciwane, nezimuncagazi. Lokhu kwenza i-quicklime ibe wusizo ikakhulukazi ezimeni eziphuthumayo zokwelashwa kwamanzi noma ekwelapheni imithombo yamanzi ngengcuphe enkulu yokungcoliswa yi-pathogen, njengakwezinye izifunda ezisathuthuka noma ngemva kwezinhlekelele zemvelo.

I-lime e-Hydrated nayo inezindawo zokubulala amagciwane ngenxa ye-alkalinity yayo. Kungasiza ukulawula ukukhula kwama-microorganisms emanzini, ikakhulukazi ezinhlelweni zokusabalalisa amanzi lapho ukugcinwa kwe-pH ene-alkaline kungavimbela ukukhula kwamagciwane athile. Nokho, amandla ayo okubulala amagciwane ngokuvamile awanamandla njengalawo e-quicklime.

Imvula kanye Nokususwa Kokungcola

Kokubili i-quicklime ne-hydrated lime ingasabela ngokungcola okunhlobonhlobo emanzini ukuze kwakheke imvula, engase isuswe ngezinqubo zokucwiliswa kwenhlabathi noma zokuhlunga. Isibonelo, bangasabela nge-phosphates ukuze benze i-calcium phosphate precipitates, esiza ukususa i-phosphorus emanzini. Lokhu kubalulekile ekuvimbeleni i-eutrophication emizimbeni yamanzi, njengoba i-phosphorus eyeqile ingaholela ekuqhakazeni kwe-algal kanye nokuncipha kwe-oxygen.

Endabeni yokukhipha izinsimbi ezisindayo, i-hydrated lime ivame ukuthandwa. Ingasabela ngama-ion ensimbi esindayo njengomthofu, IMERCURY, kanye ne-cadmium ukwenza i-insoluble metal hydroxides. Lezi zimvula zingahlukaniswa kalula namanzi, ngokunciphisa ngokuphumelelayo okuqukethwe kwensimbi esindayo. Ukusabela okuthambile kwe-lime e-hydrated uma kuqhathaniswa ne-quicklime kuyenza ifaneleke kakhulu kulolu hlelo lokusebenza, njengoba ivumela ukulawulwa okungcono kwenqubo yemvula.

Izindleko Nokusingatha Ukucatshangelwa

Izindleko ziyisici esibalulekile ekwelashweni kwamanzi. I-Quicklime ngokuvamile ibiza kakhulu - isebenza kahle kune-lime e-hydrated ngeyunithi ngayinye - ngesisekelo sobuningi. Lokhu kungenxa yokuthi i-quicklime iyimpahla eluhlaza okukhiqizwa ngayo i-hydrated lime, futhi ukucutshungulwa okwengeziwe okudingekayo ukuze kuguqulwe i-quicklime ibe umcako onamanzi kwengeza izindleko zamuva. Ezimbonini ezinkulu zokuhlanza amanzi, izindleko zokonga ngokusebenzisa i-quicklime zingaba nkulu.

Nokho, ukuphatha i-quicklime kudinga ukunakekelwa okwengeziwe. Ukusabela kwayo okushisayo emanzini kungadala ubungozi bezokuphepha uma kungalawulwa kahle. Imishini ekhethekile nezinqubo zokuphepha ziyadingeka ukuze kugcinwe, kuthuthwe, futhi kuxutshwe i-quicklime namanzi. Ngokuphambene, i-hydrated lime izinzile futhi kulula ukuyiphatha. Ingagcinwa ezitsheni ezivamile futhi ixutshwe namanzi kusetshenziswa okokusebenza okujwayelekile, okukwenza kube ukukhetha okulula kwezinye izindawo ezincane zokuhlanza amanzi noma ezimeni lapho ukuphepha nokubamba kalula kubekwa phambili kuqala.

Isiphetho

Ekuphetheni, ukukhetha phakathi kwe-quicklime kanye ne-hydrated lime ekwelapheni kwamanzi kuncike ezintweni ezihlukahlukene. Uma ubhekene namanzi ane-asidi kakhulu, udinga isibulala-magciwane esinamandla, noma ufuna izindleko - ukwelashwa okuphumelelayo ngezinga elikhulu, i-quicklime ingaba inketho engcono. Ngakolunye uhlangothi, uma udinga ukulawulwa okunembile kwenqubo yokwelapha, ugxile ekukhipheni insimbi esindayo, noma udinga into ephathwa kalula, i-hydrated lime kungaba ukukhetha okufanele kakhulu.

Ekugcineni, ukuhlaziya okuningiliziwe kwekhwalithi yamanzi, imigomo yokwelashwa, izidingo zokuphepha, kanye nemikhawulo yezindleko kuyadingeka ukuze wenze isinqumo unolwazi. Ngokucubungula lezi zici ngokucophelela, ochwepheshe bokwelashwa kwamanzi bangakhetha indlela yokwelapha esekelwe kumcako efanele kakhulu ukuze kuzuzwe izinga eliphezulu lamanzi kanye nokusebenza kahle kokwelashwa.
