Unyango lwamanzi: I-Quicklime okanye i-Hydrated Lime-Yeyiphi eNgcono?

Kwindawo ye unyango lwamanzi, ukhetho phakathi ngokukhawuleza (i-calcium oxide, i-CaO) kunye ikalika enamanzi (i-calcium hydroxide, i-Ca (OH) ₂) sisigqibo esibalulekileyo esinokuchaphazela kakhulu ukusebenza kakuhle, iindleko, kunye nefuthe lokusingqongileyo kwinkqubo yonyango. Zombini ezi zinto zidlala indima ebalulekileyo kwiinkqubo ezahlukeneyo zokucocwa kwamanzi, kodwa iimpawu zazo ezahlukeneyo kunye nokuziphatha zibenza bafaneleke ngakumbi kwiimeko ezithile. Makhe sihlolisise uthelekiso oluneenkcukacha ukuze sibone ukuba yeyiphi enokuba lolona khetho lungcono kwiimfuno zakho zokucoca amanzi.

Iimpendulo zeMichiza kunye noLungiso lwe-pH

Xa i-quicklime yongezwa emanzini, ifumana i-reaction exothermic, ivelisa ngokukhawuleza ukushisa kwaye iguqule ibe yi-hydrated lime: CaO + H₂O → Ca (OH) ₂. Oku kusabela kunamandla kakhulu kwaye kunokunyusa ubushushu bamanzi kakhulu. Ngakolunye uhlangothi, i-hydrated lime sele ikwimo ye-hydroxide kwaye inyibilika emanzini ngaphandle kokukhutshwa kobushushu obunobundlobongela.

Zombini i-quicklime kunye ne-hydrated lime ziyasebenza ekulungiseni i-pH yamanzi. Ziyi-alkalis ezinamandla ezinokuthi zinciphise amanzi ane-asidi, okwenza ukuba afanelekele unyango olongezelelweyo okanye akhuseleke ekukhutshweni. Nangona kunjalo, ngenxa yokuguqulwa okuqhubekayo kwe-quicklime kwi-lime e-hydrated emanzini, inokubonelela ngomthombo ozinzileyo we-alkalinity yokulungiswa kwe-pH. Oku kunokuba luncedo ekuphatheni amanzi amdaka emizi-mveliso aneasidi kakhulu, apho kufuneka ukonyuka okumandla nokuqhubekayo kwe-pH.

Ukubulala iintsholongwane kunye nokususwa kwePathogen

I-Quicklime's exothermic reaction, idityaniswe ne-pH ephezulu eyenzayo, iyenza ibe sisibulali-ntsholongwane esigqwesileyo. Ubushushu obuveliswayo bunokwenza iiproteni kunye nenwebu zeeseli ze-pathogens, ngelixa i-alkalinity ephezulu ibulala iibhaktheriya ezininzi, iintsholongwane kunye nezifunxi-gazi. Oku kwenza i-quicklime ibe luncedo ngakumbi kwiimeko zokucocwa kwamanzi ezingxamisekileyo okanye ekunyangeni imithombo yamanzi ngomngcipheko omkhulu wosulelo lwe-pathogen, njengakweminye imimandla ephuhlayo okanye emva kweentlekele zendalo.

Ikalika eHyithiweyo nayo ineempawu zokubulala iintsholongwane ngenxa yealkalinity yayo. Inokukunceda ukulawula ukukhula kwe-microorganisms emanzini, ngakumbi kwiinkqubo zokusasazwa kwamanzi apho ukugcinwa kwe-alkaline kancinane pH kunokuthintela ukukhula kweebhaktheriya ezithile. Nangona kunjalo, amandla ayo okubulala iintsholongwane ngokubanzi ayomelele njengaleyo ye-quicklime.

Imvula kunye nokususwa kobumdaka

Zombini i-quicklime kunye ne-hydrated lime zinokusabela ngokungcola okwahlukeneyo emanzini ukwenza imvula, enokuthi emva koko isuswe ngentlenga okanye ngeenkqubo zokuhluza. Ngokomzekelo, banokusabela nge-phosphates ukwenza i-calcium phosphate precipitates, inceda ukususa i-phosphorus emanzini. Oku kubalulekile ekuthinteleni i-eutrophication kwimizila yamanzi, njengoko i-phosphorus eninzi inokukhokelela kwi-algal blooms kunye nokunciphisa i-oxygen.

Kwimeko yokususa isinyithi esinzima, i-hydrated lime isoloko ikhethwa. Inokusabela ngee-ion zentsimbi enzima njengelothe, I-MERCURY, kunye ne-cadmium ukwenza i-insoluble metal hydroxides. Ezi precipitates ziyakwazi ukuhlukana ngokulula emanzini, ngokufanelekileyo ukunciphisa umxholo wetsimbi enzima. Ukusabela okuthambileyo kwekalika ye-hydrated xa kuthelekiswa ne-quicklime kuyenza ilunge ngakumbi kwesi sicelo, njengoko ivumela ulawulo olungcono lwenkqubo yemvula.

IiNdleko kunye nokuPhathwa kweeNgqwalasela

Iindleko ziyinto ebalulekileyo kunyango lwamanzi. I-Quicklime ngokuqhelekileyo ineendleko ezingaphezulu-zisebenza kakuhle kune-lime e-hydrated kwiyunithi nganye - isiseko sobunzima. Oku kungenxa yokuba i-quicklime yimathiriyeli ekrwada eveliswa kuyo i-hydrated lime, kunye nokulungiswa okongeziweyo okufunekayo ukuguqula i-quicklime ukuya kwi-hydrated lime yongeza kwiindleko zamva. Kwimizi-mveliso emikhulu yokucocwa kwamanzi, ugcino lweendleko ekusebenziseni i-quicklime lunokuba lukhulu.

Nangona kunjalo, ukuphatha i-quicklime kufuna ukunyameka ngakumbi. Ukusabela kwayo ngokugqithisileyo ngamanzi kunokubeka imingcipheko yokhuseleko ukuba ayilawulwa kakuhle. Izixhobo ezizodwa kunye neenkqubo zokhuseleko ziyafuneka ukugcina, ukuthutha, kunye nokuxuba i-quicklime namanzi. Ngokwahlukileyo, i-hydrated lime izinzile kwaye kulula ukuyiphatha. Iyakwazi ukugcinwa kwimigqomo eqhelekileyo kwaye ixutywe namanzi usebenzisa izixhobo eziqhelekileyo, okwenza kube lula ngakumbi ukhetho kwezinye iindawo ezincinci zokunyanga amanzi okanye kwiimeko apho ukhuseleko kunye nokulula ukuphatha kubekwe phambili.

isiphelo

Ekugqibeleni, ukhetho phakathi kwe-quicklime kunye ne-hydrated lime kunyango lwamanzi kuxhomekeke kwizinto ezahlukeneyo. Ukuba ujongene namanzi aneasidi eninzi, udinga isibulali-ntsholongwane esinamandla, okanye ujonge iindleko-unyango olusebenzayo kumlinganiselo omkhulu, i-quicklime inokuba lolona khetho lungcono. Kwelinye icala, ukuba ufuna ulawulo oluchanekileyo lwenkqubo yonyango, ugxile ekususweni kwesinyithi esinzima, okanye ufuna into ephathwayo ngokulula, ikalika yehydrated inokuba lolona khetho lufanelekileyo.

Ekugqibeleni, uhlalutyo olucacileyo lomgangatho wamanzi, iinjongo zonyango, iimfuno zokhuseleko, kunye nemiqobo yeendleko ziyimfuneko ukwenza isigqibo esinolwazi. Ngokuqwalasela ngenyameko le miba, iingcali zokucocwa kwamanzi zinokukhetha eyona ndlela ifanelekileyo yonyango esekelwe kwikalika ukuze kuphunyezwe umgangatho wamanzi nowonyango olufanelekileyo.
