I-Electrocoagulation (EC) inqubo esebenzisa ugesi ukususa ukungcola emanzini angcolile. Ihilela ukusetshenziswa kwamandla kagesi e-dc ukuncibilikisa ama-electrode ahlanziwe, abese ekhipha ama-ion ensimbi ahlangana nokungcola. Le ndlela ithole ukuthandwa ngenxa yokusebenza kwayo kahle, ubungane bemvelo, kanye nokuguquguquka ekwelapheni izinhlobo ezahlukene zamanzi angcolile.
Izimiso Zokugoqana Kwegazi
Ekuhlanganisweni kwe-electro, ugesi udlula kuma-electrode ensimbi acwiliswe emanzini angcolile. I-anode (i-electrode enhle) iyancibilika, ikhiphe ama-cation ensimbi njenge-aluminium noma insimbi emanzini. Lawa ma-ion ensimbi asabela nokungcola emanzini, akhe ama-hydroxide angancibiliki ahlangana futhi angasuswa kalula. I-cathode (i-electrode engancibiliki) ikhiqiza igesi ye-hydrogen, esiza ekuntanteni izinhlayiya ezihlanganisiwe ziye phezulu ukuze zincibilike.
Inqubo iyonke ingafingqwa ngezinyathelo ezilandelayo:
I-Electrolysis: ukunikezwa kwamandla e-dc kusetshenziswa kuma-electrode, okwenza i-anode incibilikise futhi ikhulule ama-ion ensimbi.
Ukujiya: Ama-ion ensimbi akhishwe anciphisa izindleko zezinhlayiya ezilengayo kanye nokungcola okuncibilikisiwe, okuholela ekwakhekeni kwama-aggregate amakhulu.
Ukuntanta: Amabhamuza egesi ye-hydrogen akhiqizwa ku-cathode anamathela kuma-aggregates, okubangela ukuba antante phezulu.
Ukuhlukaniswa: Udaka oluntantayo lususwa ngokususa amanzi, kuyilapho udaka oluzinzile luqoqwa phansi.
Izinzuzo Zokunikezwa Kwamandla E-DC Ku-Electrocoagulation
Ukusebenza kahle: ukunikezwa kwamandla e-DC kuvumela ukulawula okunembile phezu kwamandla kagesi kanye ne-voltage esetshenziswayo, okwenza ngcono ukuhlakazeka kwama-electrode futhi kuqinisekiswe ukuqina okuphumelelayo kwezinto ezingcolisayo.
Ubulula: Ukusethwa kwe-electrocoagulation kusetshenziswa ugesi we-DC kulula kakhulu, okuhlanganisa ugesi, ama-electrode, kanye negumbi lokusabela.
Ubungane Kwemvelo: Ngokungafani nokuhlangana kwamakhemikhali, ukuhlangana kwamakhemikhali nge-electrocoagulation akudingi ukwengezwa kwamakhemikhali angaphandle, okunciphisa ingozi yokungcola kwesibili.
Ukuguquguquka: I-EC ingalapha ukungcola okuhlukahlukene, okuhlanganisa izinsimbi ezisindayo, amakhemikhali e-organic, izinto eziqinile ezilengayo, ngisho namagciwane.
Ukusetshenziswa kwe-Electrocoagulation ekwelashweni kwamanzi angcolile
Amanzi Angcolile Ezimbonini: Ukugaya i-electrocoagulation kusebenza kahle kakhulu ekwelapheni amanzi angcolile ezimbonini aqukethe izinsimbi ezisindayo, udayi, uwoyela, nezinye izinto ezingcolisayo eziyinkimbinkimbi. Izimboni ezifana nezindwangu, ukugaya i-electroplating, kanye nemithi ziyazuza ekhonweni le-EC lokususa izinto ezinobuthi nokunciphisa isidingo se-oxygen yamakhemikhali (COD).
Amanzi Angcolile Kamasipala: I-EC ingasetshenziswa njengendlela yokwelapha eyinhloko noma yesibili yamanzi angcolile kamasipala, isiza ekususeni izinto eziqinile ezilengayo, ama-phosphate, kanye namagciwane. Ithuthukisa ikhwalithi iyonke yamanzi ahlanziwe, okwenza afaneleke ukukhishwa noma ukusetshenziswa kabusha.
Ukugeleza Kwezolimo: I-EC iyakwazi ukwelapha ukugeleza kwezolimo okuqukethe izibulala-zinambuzane, umanyolo, kanye nezinto eziphilayo. Lokhu kusetshenziswa kusiza ekunciphiseni umthelela wemisebenzi yezolimo ezindaweni zamanzi eziseduze.
Ukwelashwa Kwamanzi Emvula: I-EC ingasetshenziswa emanzini emvula ukuze kususwe inhlabathi, izinsimbi ezisindayo, nezinye izinto ezingcolisayo, okukuvimbela ukuthi zingangeni emanzini emvelo.
Amapharamitha Okusebenza Nokwenza Kusebenze Kahle
Ukusebenza kahle kwe-electrocoagulation kuncike kumingcele eminingana yokusebenza, okuhlanganisa:
Ubuningi Bamanje: Inani lamanje elisetshenziswayo ngeyunithi ngayinye yendawo ye-electrode lithinta izinga lokukhululwa kwe-ion yensimbi kanye nokusebenza kahle kwenqubo. Ubuningi bamanje obuphezulu bungandisa ukusebenza kahle kokwelashwa kodwa futhi bungabangela ukusetshenziswa kwamandla okuphezulu kanye nokuguguleka kwe-electrode.
Izinto ze-Electrode: Ukukhethwa kwezinto ze-electrode (ngokuvamile i-aluminium noma insimbi) kuthonya uhlobo kanye nokusebenza kahle kokuqina kwe-coagulation. Izinto ezahlukene zikhethwa ngokusekelwe kungcoliseko oluthile olukhona emanzini angcolile.
i-pH: I-pH yamanzi angcolile ithinta ukuncibilika kanye nokwakheka kwama-hydroxide ensimbi. Amazinga e-pH afanele aqinisekisa ukusebenza kahle okukhulu kokujiya kanye nokuqina kwama-aggregates akhiwe.
Ukucushwa Kwe-Electrode: Ukuhleleka kanye nesikhala sama-electrode kuthinta ukusatshalaliswa kwensimu kagesi kanye nokufana kwenqubo yokwelapha. Ukucushwa okufanele kuthuthukisa ukuxhumana phakathi kwama-ion ensimbi kanye nezinto ezingcolisayo.
Isikhathi Sokusabela: Isikhathi sokujiya kwe-electro sithinta izinga lokususwa kokungcola. Isikhathi esanele sokusabela siqinisekisa ukujiya okuphelele kanye nokuhlukaniswa kokungcola.
Izinselele Neziqondiso Zesikhathi Esizayo
Naphezu kwezinzuzo zayo, i-electrocoagulation ibhekene nezinselele ezithile:
Ukusetshenziswa kwe-Electrode: Ukuzidela kwe-anode kuholela ekusetshenzisweni kwayo kancane kancane, okudinga ukushintshwa noma ukuvuselelwa njalo.
Ukusetshenziswa Kwamandla: Nakuba ukunikezwa kwamandla e-DC kuvumela ukulawula okunembile, kungadinga amandla amaningi, ikakhulukazi emisebenzini emikhulu.
Ukuphathwa Kodaka: Le nqubo ikhiqiza udaka oludinga ukuphathwa nokulahlwa kahle, okwengeza ezindleleni zokusebenza.
Ucwaningo lwesikhathi esizayo kanye nentuthuko kuhloswe ukubhekana nalezi zinselele ngokuthi:
Ukuthuthukisa Izinto Zokusebenza Zama-Electrode: Ukuthuthukisa izinto zokusebenza zama-electrode ezihlala isikhathi eside nezisebenza kahle ukuze kuncishiswe ukusetshenziswa nokuthuthukisa ukusebenza.
Ukuthuthukisa Ukunikezwa Kwamandla: Ukusebenzisa amasu okunikezwa kwamandla athuthukisiwe, njenge-pulsed DC, ukunciphisa ukusetshenziswa kwamandla nokuthuthukisa ukusebenza kahle kokwelashwa.
Ukuthuthukisa Ukuphathwa Kodaka: Izindlela ezintsha zokunciphisa nokuqinisekisa udaka, njengokuguqula udaka lube yimikhiqizo ewusizo.
Ekuphetheni, ukunikezwa kukagesi kwe-DC kudlala indima ebalulekile ekuhlanganisweni kwe-electrocoagulation ekuphathweni kwamanzi amdaka, okunikeza ikhambi elisebenzayo, elinobungani nemvelo, neliguquguqukayo lokususa ukungcola okuhlukahlukene. Ngokuthuthuka okuqhubekayo kanye nokuthuthukiswa, ukuhlanganiswa kwe-electrocoagulation sekulungele ukuba yindlela ephumelela kakhulu futhi eqhubekayo yokubhekana nezinselele zokuphathwa kwamanzi amdaka emhlabeni jikelele.
