I-Electrocoagulation (EC) iyinqubo esebenzisa amandla kagesi ukususa ukungcola emanzini angcolile. Kubandakanya ukusetshenziswa kwamandla kagesi e-dc ukuncibilikisa ama-electrode omhlatshelo, abese ekhulula ama-ion ensimbi ahlangana nezinto ezingcolisayo. Le ndlela isithole ukuduma ngenxa yokusebenza kwayo kahle, ubungane bemvelo, kanye nokuguquguquka ekwelashweni kwezinhlobo ezahlukene zamanzi angcolile.
Izimiso ze-Electrocoagulation
Ku-electrocoagulation, amandla kagesi adluliswa ngama-electrode ensimbi acwiliswe emanzini angcolile. I-anode (positive electrode) iyancibilika, ikhiphe ama-cation ensimbi njenge-aluminium noma insimbi emanzini. Lawa ma-ion ensimbi ahlangana nokungcola emanzini, akhe ama-insoluble hydroxides ahlanganayo futhi angasuswa kalula. I-cathode (i-electrode engeyiyo) ikhiqiza igesi ye-hydrogen, esiza ekuntanteni izinhlayiya ezijiyile phezulu ukuze ziskimming.
Inqubo iyonke ingafingqwa ngezinyathelo ezilandelayo:
I-Electrolysis: amandla kagesi e-dc asetshenziswa kuma-electrode, okwenza ukuthi i-anode incibilike futhi ikhulule ama-ion ensimbi.
I-Coagulation: Ama-ion ensimbi akhululiwe enza kube lula ukukhokhiswa kwezinhlayiya ezimisiwe kanye nokungcola okuncibilikisiwe, okuholela ekwakhekeni kwama-aggregate amakhulu.
I-Flotation: Amabhamuza egesi ye-Hydrogen akhiqizwa ku-cathode anamathela kuma-aggregates, abangele ukuthi antante phezulu.
Ukwehlukanisa: Udaka oluntantayo lususwa ngokushushuluza, kuyilapho udaka oluhleliwe luqoqwa phansi.
Izinzuzo ze-DC Power Supply ku-Electrocoagulation
Ukusebenza kahle: Ukunikezwa kwamandla kwe-dc kuvumela ukulawula okunembayo phezu kwamanje kanye ne-voltage esetshenziswayo, kwenze kahle ukuhlakazeka kwama-electrode kanye nokuqinisekisa ukuhlangana okusebenzayo kokungcola.
Ubulula: Ukusethwa kwe-electrocoagulation kusetshenziswa ugesi we-DC kulula, kuhlanganisa ukunikezwa kwamandla, ama-electrode, negumbi lokusabela.
Ubungane Bemvelo: Ngokungafani nokuhlangana kwamakhemikhali, i-electrocoagulation ayidingi ukungezwa kwamakhemikhali angaphandle, kunciphisa ingozi yokungcoliswa kwesibili.
I-Versatility: I-EC ingakwazi ukwelapha ukungcola okuhlukahlukene, okuhlanganisa izinsimbi ezisindayo, izinhlanganisela eziphilayo, okuqinile okumisiwe, ngisho namagciwane.
Izicelo ze-Electrocoagulation ku-Wastewater Treatment
Amanzi Angcolile Ezimboni: I-Electrocoagulation iphumelela kakhulu ekwelapheni amanzi angcolile ezimbonini aqukethe izinsimbi ezisindayo, odayi, uwoyela, nokunye ukungcola okuyinkimbinkimbi. Izimboni ezifana nezindwangu, i-electroplating, nemithi ziyazuza ekhonweni le-EC lokususa izinto ezinobuthi nokunciphisa isidingo samakhemikhali komoyampilo (COD).
Amanzi Angcolile Kamasipala: I-EC ingasetshenziswa njengendlela yokuqala noma yesibili yokuhlanza amanzi angcolile kamasipala, esiza ukususa okuqinile okumisiwe, ama-phosphates, kanye namagciwane. Ithuthukisa ikhwalithi isiyonke yamanzi ahlanzekile, iwenze afaneleke ukuchithwa noma ukuphinda asetshenziswe.
I-Agricultural Runoff: I-EC iyakwazi ukwelapha ukugeleza kwezolimo okuqukethe izibulala-zinambuzane, umanyolo, nezinto eziphilayo. Lolu hlelo lokusebenza lusiza ekunciphiseni umthelela wemisebenzi yezolimo emanzini aseduze.
Ukwelapha Amanzi Esiphepho: I-EC ingasetshenziswa ekugelezeni kwamanzi emvula ukuze kususwe izinhlaka, izinsimbi ezisindayo, nokunye ukungcola, kuvinjwe ukuthi zingangeni emanzini emvelo.
Amapharamitha Okusebenza Nokuthuthukisa
Ukusebenza kwe-electrocoagulation kuncike kumingcele ethile yokusebenza, okuhlanganisa:
Ukuminyana Kwamanje: Inani lamanje elisetshenziswayo endaweni ngayinye ye-electrode lithinta izinga lokukhululwa kwe-ion yensimbi kanye nokusebenza kahle okuphelele kwenqubo. Ukuminyana okuphezulu kwamanje kungakhuphula ukusebenza kahle kokwelashwa kodwa kungase futhi kuholele ekusetshenzisweni okuphezulu kwamandla nokuguga kwama-electrode.
I-Electrode Material: Ukukhethwa kwezinto ze-electrode (ngokuvamile i-aluminium noma insimbi) kuthonya uhlobo nokusebenza kahle kokuhlangana. Izinto ezihlukene zikhethwa ngokusekelwe ekungcoleni okuthile okukhona emanzini angcolile.
I-pH: I-pH yamanzi angcolile ithinta ukuncibilika nokwakheka kwama-hydroxide ensimbi. Amazinga e-pH afanelekile aqinisekisa ukusebenza kahle okukhulu kokuhlangana kanye nokuzinza kwama-aggregate akhiwe.
Ukucushwa kwe-Electrode: Ukuhlelwa nokuhlukaniswa kwesikhala kwama-electrode kunomthelela ekusabalaliseni inkambu kagesi kanye nokufana kwenqubo yokwelapha. Ukumisa kahle kuthuthukisa ukuxhumana phakathi kwama-ion ensimbi nezinto ezingcolisayo.
Isikhathi Sokusabela: Ubude besikhathi se-electrocoagulation buthinta izinga lokususwa kokungcola. Isikhathi esanele sokuphendula siqinisekisa ukuhlangana okuphelele nokuhlukaniswa kwezinto ezingcolisayo.
Izinselele kanye Neziqondiso Zesikhathi esizayo
Naphezu kwezinzuzo zayo, i-electrocoagulation ibhekene nezinselelo ezithile:
Ukusetshenziswa kwe-Electrode: Imvelo yomhlatshelo ye-anode iholela ekusetshenzisweni kwayo kancane kancane, okudinga ukushintshwa ngezikhathi ezithile noma ukukhiqizwa kabusha.
Ukusetshenziswa kwamandla: Nakuba amandla kagesi e-DC avumela ukulawula okunembayo, angadla amandla, ikakhulukazi emisebenzini emikhulu.
Ukulawulwa Kwemfucumfucu: Inqubo ikhiqiza udaka oludinga ukuphathwa ngendlela efanele futhi ilahlwe, okwengeza ezindlekweni zokusebenza.
Ucwaningo lwesikhathi esizayo kanye nentuthuko ihlose ukubhekana nalezi zinselele ngokuthi:
Ukuthuthukisa Izinto ze-Electrode: Ukuthuthukisa izinto ezihlala isikhathi eside nezisebenza kahle zama-electrode ukunciphisa ukusetshenziswa nokuthuthukisa ukusebenza.
Ukuthuthukisa Ukunikezwa kwamandla: Ukusebenzisa amasu okuphakela amandla athuthukile, njenge-pulsed DC, ukunciphisa ukusetshenziswa kwamandla kanye nokwenza ngcono ukwelashwa.
Ukuthuthukisa Ukuphatha Udaka: Izindlela ezintsha zokunciphisa udaka nokuqinisa amandla, njengokuguqula udaka lube yimikhiqizo ewusizo.
Sengiphetha, ukunikezwa kwamandla kagesi e-DC kudlala indima ebalulekile ku-electrocoagulation yokwelashwa kwamanzi angcolile, kunikeze isisombululo esisebenzayo, esinobungani nemvelo, nesiguquguqukayo sokususa ukungcola okuhlukahlukene. Ngokuthuthuka okuqhubekayo kanye nokwenza kahle, i-electrocoagulation isilungele ukuba yindlela esebenzayo futhi esimeme yokubhekana nezinselele zomhlaba zokuhlanza amanzi angcolile.
