I-Electrocoagulation (EC) yinkqubo esebenzisa umsinga wombane ukususa ungcoliseko kumanzi amdaka. Ibandakanya ukusetyenziswa kombane we-dc ukunyibilikisa i-electrode yedini, ethi emva koko ikhuphe ii-ion zentsimbi ezidityaniswa nezinto ezingcolisayo. Le ndlela ifumene ukuthandwa ngenxa yokusebenza kwayo, ukuhambelana kokusingqongileyo, kunye nokuguquguquka ekuphatheni iintlobo ezahlukeneyo zamanzi amdaka.
Imigaqo ye-Electrocoagulation
Kwi-electrocoagulation, umbane wombane ugqithiswa ngee-electrodes zetsimbi ezifakwe emanzini amdaka. I-anode (i-electrode e-positive) iyancibilika, ikhuphe ii-cations zetsimbi ezifana ne-aluminium okanye isinyithi emanzini. Ezi ion zesinyithi zisabela kunye nongcoliseko emanzini, zenze i-insoluble hydroxides edibanisa kwaye inokususwa ngokulula. I-cathode (i-electrode engalunganga) ivelisa igesi ye-hydrogen, enceda ekudadaniseni amasuntswana ajiyileyo ukuya kumphezulu wokutyibiliza.
Inkqubo iyonke ingashwankathelwa ngala manyathelo alandelayo:
I-Electrolysis: ukunikezelwa kwamandla e-dc kusetyenziswe kwi-electrodes, kubangela ukuba i-anode ichithe kwaye ikhulule i-ion zetsimbi.
I-Coagulation: Ii-ion zetsimbi ezikhutshiweyo zinciphisa iintlawulo zamasuntswana amisiweyo kunye nongcoliseko olunyibilikisiweyo, okukhokelela ekwenziweni kwee-aggregates ezinkulu.
I-Flotation: Amaqamza erhasi ye-Hydrogen aveliswa kwi-cathode ancamathela kwi-aggregates, ebangela ukuba adande phezulu.
Ukwahlula: I-sludge edadayo iyasuswa ngokutyibilika, ngelixa i-sludge ehleliweyo iqokelelwa ukusuka ezantsi.
Izinto ezilungileyo zeDC Power Supply in Electrocoagulation
Ukusebenza kakuhle: Unikezelo lwamandla e-dc luvumela ulawulo oluchanekileyo phezu kwangoku kunye ne-voltage esetyenzisiweyo, ukwandisa ukuchithwa kwee-electrodes kunye nokuqinisekisa ukudibanisa okusebenzayo kwezinto ezingcolileyo.
Ubulula: Ukuseta i-electrocoagulation usebenzisa unikezelo lombane lwe-DC kulula, kubandakanya unikezelo lwamandla, i-electrode, kunye negumbi lokuphendula.
Ubungane beNdalo: Ngokungafani ne-chemical coagulation, i-electrocoagulation ayifuni ukongezwa kweekhemikhali zangaphandle, ukunciphisa umngcipheko wokungcola okwesibini.
I-Versatility: I-EC inokunyanga uluhlu olubanzi lwezinto ezingcolisayo, ezibandakanya isinyithi esinzima, iikhompawundi ze-organic, izinto eziqinileyo ezinqunyiweyo, kunye ne-pathogens.
Usetyenziso lwe-Electrocoagulation kunyango lwamanzi amdaka
Amanzi amdaka kwimizi-mveliso: I-Electrocoagulation iyasebenza kakhulu ekuphatheni amanzi amdaka emizi-mveliso aqulathe iintsimbi ezinzima, iidayi, i-oyile, kunye nezinye izinto ezingcolisayo ezintsonkothileyo. Amashishini afana namalaphu, i-electroplating, kunye namayeza axhamla kwisakhono se-EC sokususa izinto eziyityhefu kunye nokunciphisa imfuno ye-oksijini yemichiza (COD).
Amanzi amdaka kaMasipala: I-EC ingasetyenziswa njengendlela yokuqala okanye yesibini yonyango lwamanzi amdaka kamasipala, inceda ekususeni izinto eziqinileyo ezinqunyanyisiweyo, iifosfaite, kunye neentsholongwane ezibangela izifo. Inyusa umgangatho uwonke wamanzi acociweyo, iwenza alungele ukukhutshelwa okanye ukuphinda asetyenziswe.
I-Agricultural Runoff: I-EC iyakwazi ukunyanga amanzi aphumayo ezolimo aqulethe amayeza okubulala izitshabalalisi, izichumisi, kunye nezinto eziphilayo. Esi sicelo sinceda ekunciphiseni impembelelo yemisebenzi yezolimo kwiindawo zamanzi ezikufutshane.
Unyango lwamanzi esitshi: I-EC ingasetyenziswa ekubalekeni kwamanzi esiphango ukususa intlenga, isinyithi esinzima, kunye nolunye ungcoliseko, lubathintele ekungeneni emanzini endalo.
IiParameters zokuSebenza kunye noPhuculo
Ukusebenza kwe-electrocoagulation kuxhomekeke kwiiparamitha ezininzi zokusebenza, kubandakanya:
Uxinano lwangoku: Ubungakanani obusetyenziswayo ngoku kwiyunithi yendawo ye-electrode ichaphazela izinga lokukhutshwa kwe-ion yensimbi kunye nokusebenza kakuhle kwenkqubo. Uxinaniso oluphezulu lwangoku lunokunyusa ukusebenza konyango kodwa lunokukhokelela ekusebenziseni amandla aphezulu kunye nokunxitywa kwe-electrode.
Izinto ze-Electrode: Ukukhethwa kwezinto ze-electrode (ngokuqhelekileyo i-aluminium okanye isinyithi) ichaphazela uhlobo kunye nokusebenza kakuhle kwe-coagulation. Izinto ezahlukeneyo zikhethwa ngokusekelwe kwizinto ezingcolileyo ezikhoyo kumanzi amdaka.
i-pH: I-pH yamanzi amdaka ichaphazela ukunyibilika kunye nokwakheka kweehydroxide zesinyithi. Amanqanaba e-pH afanelekileyo aqinisekisa ukusebenza kakuhle kokudibanisa kunye nokuzinza kwee-aggregates ezenziweyo.
I-Electrode Configuration: Ulungiselelo kunye nezithuba ze-electrode zinefuthe ekusasazweni kwendawo yombane kunye nokufana kwenkqubo yonyango. Ukucwangciswa okufanelekileyo kwandisa uqhagamshelwano phakathi kwee-ion zetsimbi kunye nokungcola.
Ixesha lokuphendula: Ubude bexesha le-electrocoagulation buchaphazela ubungakanani bokususwa kongcoliseko. Ixesha elaneleyo lokuphendula liqinisekisa ukudibanisa okupheleleyo kunye nokwahlulwa kwezinto ezingcolisayo.
Imingeni kunye nezikhokelo zexesha elizayo
Ngaphandle kweenzuzo zayo, i-electrocoagulation ijongene nemingeni ethile:
