I-Electrocoagulation (EC) yinkqubo esebenzisa umbane wamanzi ukususa izinto ezingcolisayo emanzini amdaka. Ibandakanya ukusetyenziswa kombane we-dc ukunyibilikisa ii-electrode ezibingelelwayo, ezithi emva koko zikhuphe ii-ion zesinyithi ezijiyayo kunye nezinto ezingcolisayo. Le ndlela ifumene udumo ngenxa yokusebenza kwayo kakuhle, ukuba nobuhlobo nokusingqongileyo, kunye nokuguquguquka ekuphatheni iintlobo ezahlukeneyo zamanzi amdaka.
Imigaqo ye-Electrocoagulation
Kwi-electrocoagulation, umsinga wombane udlula kwii-electrode zesinyithi ezifakwe emanzini amdaka. I-anode (i-electrode elungileyo) iyanyibilika, ikhuphe ii-cation zesinyithi ezifana ne-aluminium okanye i-iron emanzini. Ezi i-ion zesinyithi zisabela kunye nongcoliseko olusemanzini, zenze ii-hydroxide ezinganyibilikiyo ezihlangana kwaye zinokususwa ngokulula. I-cathode (i-electrode engalunganga) ivelisa igesi ye-hydrogen, enceda ekutsaleni amasuntswana adibeneyo aye kumphezulu ukuze anciphe.
Inkqubo iyonke ingashwankathelwa ngala manyathelo alandelayo:
I-Electrolysis: umbane we-dc usetyenziswa kwii-electrodes, nto leyo ebangela ukuba i-anode inyibilike ize ikhuphe ii-ion zesinyithi.
Ukuxinana: Ii-ion zesinyithi ezikhutshiweyo zithintela iintlawulo zeesuntswana ezixhonyiweyo kunye nezinto ezingcolisayo ezinyibilikisiweyo, nto leyo ekhokelela ekwakhiweni kwee-aggregates ezinkulu.
Ukudada: Amaqamza egesi yehydrogen aveliswa kwi-cathode anamathela kwi-aggregates, nto leyo ebangela ukuba adade aye phezulu.
Ukwahlulwa: Inkunkuma edadayo isuswa ngokususa amanzi, ngelixa inkunkuma ehleliyo iqokelelwa ezantsi.
Iingenelo zobonelelo lwamandla e-DC kwi-Electrocoagulation
Ukusebenza kakuhle: umbane we-dc uvumela ulawulo oluchanekileyo phezu kombane kunye ne-voltage esetyenzisiweyo, okwenza ngcono ukunyibilika kwee-electrodes kunye nokuqinisekisa ukujiya okusebenzayo kwezinto ezingcolisayo.
Ubulula: Ukuseta i-electrocoagulation kusetyenziswa umbane we-DC kulula kakhulu, kuquka umbane, ii-electrode, kunye negumbi lokusabela.
Ubuhlobo Nokusingqongileyo: Ngokungafaniyo nokudibanisa iikhemikhali, ukuxuba iikhemikhali nge-electrocoagulation akudingi kongezwa kweekhemikhali zangaphandle, nto leyo enciphisa umngcipheko wongcoliseko lwesibini.
Ukuguquguquka: I-EC inganyanga uluhlu olubanzi lwezinto ezingcolisayo, kuquka iintsimbi ezinzima, iikhompawundi ze-organic, izinto eziqinileyo ezixhonyiweyo, kwanezifo ezibangela izifo.
Ukusetyenziswa kwe-Electrocoagulation kuNyango lwaManzi amdaka
Amanzi Amdaka Emizi-mveliso: I-Electrocoagulation isebenza kakhulu ekunyangeni amanzi amdaka emizi-mveliso aneentsimbi ezinzima, iidayi, iioyile, kunye nezinye izinto ezingcolisayo ezintsonkothileyo. Amashishini afana neempahla zelaphu, i-electroplating, kunye namayeza axhamla kubuchule be-EC bokususa izinto ezinobuthi kunye nokunciphisa imfuno ye-oxygen yamakhemikhali (COD).
Amanzi amdaka kaMasipala: I-EC ingasetyenziswa njengendlela yokuqala okanye yesibini yonyango lwamanzi amdaka kaMasipala, inceda ukususa izinto eziqinileyo ezixhonyiweyo, iiphosphates, kunye neentsholongwane. Iphucula umgangatho wamanzi acociweyo, okwenza afaneleke ukukhutshwa okanye ukuphinda asetyenziswe.
Ukuchitheka kwamanzi kwizolimo: I-EC iyakwazi ukunyanga ukuchitheka kwamanzi kwizolimo okuqulethe izibulali-zinambuzane, izichumisi, kunye nezinto eziphilayo. Olu setyenziso lunceda ekunciphiseni impembelelo yemisebenzi yezolimo kwiindawo zamanzi ezikufutshane.
Unyango lwamanzi emvula: I-EC ingafakwa emanzini emvula ukuze kususwe inkunkuma, iintsimbi ezinzima, kunye nezinye izinto ezingcolisayo, nto leyo ethintela ukuba zingangeni emanzini endalo.
Iiparameters zokusebenza kunye nokuphucula
Ukusebenza kwe-electrocoagulation kuxhomekeke kwiiparameter ezininzi zokusebenza, kuquka:
Uxinano lwangoku: Ubungakanani bombane osetyenziswayo ngeyunithi yendawo ye-electrode buchaphazela izinga lokukhululwa kwee-ion zesinyithi kunye nokusebenza kakuhle kwenkqubo iyonke. Uxinano lwangoku oluphezulu lunokunyusa ukusebenza kakuhle konyango kodwa lunokukhokelela ekusetyenzisweni kwamandla aphezulu kunye nokuguguleka kwe-electrode.
Izinto ze-Electrode: Ukukhethwa kwezinto ze-electrode (ezidla ngokuba yi-aluminium okanye isinyithi) kuchaphazela uhlobo kunye nokusebenza kakuhle kokujiya. Izinto ezahlukeneyo zikhethwa ngokusekelwe kungcoliseko oluthile olukhoyo emanzini amdaka.
i-pH: I-pH yamanzi amdaka ichaphazela ukunyibilika kunye nokwenziwa kwee-hydroxide zesinyithi. Amanqanaba e-pH afanelekileyo aqinisekisa ukusebenza kakuhle kokujiya kunye nozinzo lwee-aggregates ezenziweyo.
Uqwalaselo lwe-Electrode: Ulungiselelo kunye nomgama wee-electrode kuchaphazela ukusasazwa kwentsimi yombane kunye nokufana kwenkqubo yonyango. Uqwalaselo olufanelekileyo luphucula unxibelelwano phakathi kwee-ion zesinyithi kunye nezinto ezingcolisayo.
