Indima ye-calcium chloride kunyango lwamanzi amdaka

Okokuqala, indlela yokucoca amanzi amdaka ikakhulu ibandakanya ukunyangwa ngokwasemzimbeni kunye nokunyangwa kweekhemikhali.Indlela yomzimba kukusebenzisa izinto ezahlukeneyo zokucoca ezinobungakanani obuhlukeneyo bepore, ukusetyenziswa kwe-adsorption okanye iindlela zokuthintela, ukungcola emanzini kukhutshelwa ngaphandle, eyona nto ibaluleke kakhulu kwindlela yokubhengeza kukufakwa ngekhabhoni esebenzayo, indlela yokuthintela. kukudlulisa amanzi kwizinto zokucoca, ukuze umthamo omkhulu wokungcola ungadluli, kwaye emva koko ufumane amanzi acocekileyo ngakumbi.Ukongeza, indlela ebonakalayo ikwabandakanya indlela yokumisa, okukuvumela ukungcola kunye nenxalenye encinci ukudada phezu kwamanzi ukuloba ngaphandle, okanye ukungcola okunomlinganiselo omkhulu we-precipitate phantsi komphezulu, uze ufumane.Indlela yeekhemikhali kukusebenzisa iindidi ngeendidi zeekhemikhali ukuguqula ubumdaka obusemanzini bube zizinto ezingenabungozi kangako emzimbeni womntu, okanye ubumdaka bugxininiswe, indlela yonyango yemichiza kufuneka isetyenziswe ixesha elide ukongeza i-alum amanzi, emva kokuqokelela ukungcola emanzini, umthamo uba mkhulu, ungasebenzisa indlela yokucoca ukususa ukungcola.

I-Calcium chloride, ikhemikhali ehlala isetyenziswa kunyango lwamanzi amdaka, iyikhompawundi ye-inorganic eyityuwa eyenziwe nge-chlorine kunye ne-calcium, i-ionic halide eqhelekileyo.I-Chloride ion inokucolisa amanzi, ibulale iintsholongwane eziyingozi, kwaye inciphise ubutyhefu bamanzi.I-calcium ion ingathatha indawo ye-cations yesinyithi equlethwe emanzini, yahlula kwaye ingabandakanyi i-ion yensimbi enetyhefu, kwaye isuse i-calcium ion precipitation, enesiphumo esihle sokubulala iintsholongwane kunye nesiphumo sokucoca.

Oku kulandelayo kukwazisa indima ethile ye-calcium chloride kunyango lwelindle:

1. I-calcium chloride echithwe emanzini emva kokuba i-ion ye-chloride ibe nefuthe lokuvala inzala.

2. I-calcium ions ingathatha indawo ye-cations yetsimbi kumanzi amdaka, ngakumbi kwinkqubo yokucoca amanzi amdaka aqukethe ii-cations zetsimbi.Ukuze kuncitshiswe umonakalo wezinto ezinobuthi ezinobuthi kakhulu kwi-cations zetsimbi kwicandelo le-biochemical, i-calcium chloride isetyenziselwa inkqubo yokunyanga kwangaphambili ukususa ezi zinto ezinobuthi kunye neziyingozi, ezidlala indima ebalulekileyo.Ukuba le nto isetyenziswe kwicandelo lamanzi amdaka, ii-ion zekloridi zidlala indima ye-bactericide.I-calcium ion yenze i-calcium hydroxide encitshisiweyo kwaye yasuswa yimvula.

3. I-PH neutralization kunye nokulawulwa kwangaphambili kwenethiwekhi yombhobho we-acidic wamanzi amdaka ukwandisa ubomi benkonzo yomnatha wombhobho.

Inkqubo yesicelo esithe ngqo: Emva kokuba amanzi amdaka eqokelelwe kwitanki yokulawula, amanzi amdaka aphakanyiselwa kwitanki yokudibanisa ngempompo yokuphakamisa.Itanki ye-coagulation ihlukaniswe kwiinkqubo ezimbini zokuxuba okucothayo kunye nokuxuba ngokukhawuleza, izigaba ezine zokuphendula.Kwitanki yokuxuba ngokukhawuleza, i-sodium hydroxide yongezwa kwipompo ye-dosing ukulungelelanisa i-PH yamanzi adibeneyo kwi-tank ukuya kwi-8, kunye ne-polyaluminium chloride e-soluble yamanzi kunye ne-calcium chloride yongezwa ngexesha elifanayo.Ngokudibanisa i-polyacrylamide ye-flocculant kwitanki yokuxuba ecothayo, i-calcium chloride particles eyenziwe i-coagulate enye kwenye ukuze yenze i-granular floc enkulu;Emva kwe-flocculation, amanzi amdaka angena kwitanki ye-sedimentation, ngokuhlaliswa kwendalo ukufezekisa injongo yokwahlulwa kolwelo oluqinileyo, i-supernatant yaphuphuma ukusuka kwindawo ephezulu yetanki ye-sedimentation, kwaye emva koko yaya kwi-coagulation precipitation yesibini.Emva kwe-coagulation yesibini kunye nokunyangwa kwemvula, amanzi adlula kwi-bag filter kunye ne-carbon filter esebenzayo kwi-acid-base neutralization pool yecala lomnini emva kokudlula ukufunyanwa kwe-intanethi ye-fluoride ions, kwaye ke ixabiso le-pH lihlengahlengiswa kwaye likhutshwe.Amanzi angafanelekanga akhutshelwa kwitanki yokulungiswa emva koko acocwe.
