Electrocoagulation (EC) inzira inoshandisa magetsi kubvisa tsvina kubva mumvura yakasviba. Inosanganisira kushandisa simba remagetsi reDC kunyungudutsa maelectrode ekubikisa, ayo anozoburitsa maion esimbi anobatana nezvinosvibisa. Nzira iyi yave kufarirwa nekuda kwekushanda kwayo, hushamwari hwezvakatipoteredza, uye hunyanzvi hwayo mukurapa marudzi akasiyana-siyana emvura yakasviba.
Nheyo dzeElectrocoagulation
Mukushandiswa kwemagetsi, magetsi anopfuudzwa nemaelectrode esimbi akanyudzwa mumvura yakasviba. Anode (positive electrode) inonyunguduka, ichiburitsa macation esimbi akadai searuminiyamu kana iron mumvura. Aya maion esimbi anosangana nezvinosvibisa mumvura, zvichiita mahydroxide asinganyunguduki anoungana uye anogona kubviswa zviri nyore. Cathode (negative electrode) inoburitsa hydrogen gasi, iyo inobatsira mukuyangarara kwezvidimbu zvakaungana pamusoro kuti zvibude.
Maitiro ese anogona kupfupikiswa mumatanho anotevera:
Electrolysis: DC power supply inoiswa kuma electrodes, zvichiita kuti anode inyungudike uye ibudise ma ions esimbi.
Kubatana: Maion esimbi anoburitswa anodzima simba rezvinhu zvakasungirirwa uye tsvina yakanyungudutswa, zvichiita kuti pave nezvinhu zvakakura.
Kuyangarara: Mabhubhu egasi rehydrogen anogadzirwa pa cathode inonamira pazvikamu, zvichiita kuti zviyangarara pamusoro.
Kupatsanurwa: Tsvina inoyangarara inobviswa nekubviswa kwetsvina, ukuwo tsvina yakagara ichitorwa kubva pasi.
Mabhenefiti eDC Power Supply muElectrocoagulation
Kushanda zvakanaka: magetsi eDC anobvumira kutonga kwakanyatsojeka pamusoro pemagetsi nemagetsi ari kushandiswa, zvichiita kuti maelectrode agadzikane zvakanaka uye kuve nechokwadi chekuti tsvina inovharika zvakanaka.
Zviri Nyore: Kugadzika kwemagetsi ekubatanidza ma "electrocoagulation" uchishandisa DC power supply kuri nyore, kunosanganisira magetsi, ma "electrodes", uye reaction chamber.
Hushamwari Hwezvakatipoteredza: Kusiyana nekushandiswa kwemakemikari mukubatanidza, kushandiswa kwemagetsi hakudi kuwedzerwa kwemakemikari ekunze, zvichideredza njodzi yekusvibiswa kwechipiri.
Kuchinja-chinja: EC inogona kurapa tsvina dzakasiyana-siyana, kusanganisira simbi dzinorema, makemikari emuchadenga, zvinhu zvakasimba zvakamiswa, uye kunyange hutachiona.
Mashandisirwo eElectrocoagulation mukurapa mvura yakasviba
Mvura Yakasviba Yemumaindasitiri: Kubatanidza simbi nemagetsi kunoshanda zvikuru mukurapa mvura yakasviba yemumaindasitiri ine simbi dzinorema, madhayi, mafuta, nezvimwe zvinosvibisa zvakaoma. Maindasitiri akadai semachira, electroplating, uye mishonga anobatsirwa nekukwanisa kweEC kubvisa zvinhu zvine chepfu uye kuderedza kudiwa kweokisijeni yemakemikari (COD).
Mvura Yakasviba yeMunicipal: EC inogona kushandiswa senzira yekutanga kana yechipiri yekurapa mvura yakasviba yemunicipal, ichibatsira kubvisa zvinhu zvakaoma zvakasungirirwa, phosphates, uye utachiona. Inosimudzira kunaka kwemvura yakanatswa, zvichiita kuti ikodzere kubudiswa kana kushandiswazve.
Mvura inoyerera muvhu: EC inokwanisa kurapa mvura inoyerera muvhu ine mishonga yekuuraya zvipembenene, fetereza, nezvimwe zvinhu zvipenyu. Kushandiswa uku kunobatsira kuderedza kukanganiswa kwemabasa ekurima paminda yemvura iri pedyo.
Kurapa Mvura Yedutu: EC inogona kushandiswa pakuyerera kwemvura yedutu kubvisa tsvina, simbi dzinorema, nezvimwe zvinosvibisa, zvichidzivirira kupinda mumvura yechisikigo.
MaParameter Ekushanda uye Kugadzirisa
Kubudirira kwe electrocoagulation kunoenderana nematanho akati wandei ekushanda, anosanganisira:
Kuwanda Kwemagetsi: Huwandu hwemagetsi anoshandiswa pachikamu chimwe nechimwe cheelectrode hunokanganisa mwero wekuburitswa kwemaion esimbi uye kushanda zvakanaka kwemaitiro acho. Kuwanda kwemagetsi kunogona kuwedzera kushanda zvakanaka kwekurapa asi kunogonawo kukonzera kushandiswa kwesimba rakawanda uye kupera kwemagetsi.
Zvinhu zveElectrode: Kusarudzwa kwezvinhu zveelectrode (zvinowanzova aruminiyamu kana simbi) kunokanganisa mhando uye kushanda zvakanaka kwecoagulation. Zvinhu zvakasiyana zvinosarudzwa zvichienderana nezvinosvibisa zviripo mumvura yakasviba.
pH: pH yemvura yakasviba inokanganisa kunyungudika uye kuumbwa kwesimbi hydroxides. Mazinga epH akakodzera anoita kuti ma "coagulation" ashande zvakanaka uye kugadzikana kwema "aggregates" akaumbwa.
Kugadzika kweElectrode: Kurongeka uye nzvimbo yemaelectrode zvinokanganisa kupararira kwesimba remagetsi uye kufanana kwemaitiro ekugadzirisa. Kugadzika kwakakodzera kunovandudza kubatana pakati pemaayoni esimbi nezvinhu zvinosvibisa.
Nguva Yekuita: Nguva yekushandiswa kwemagetsi inokanganisa huwandu hwekubvisa tsvina. Nguva yakakwana yekuita inoita kuti tsvina iome uye iparadzaniswe.
Matambudziko uye Nzira dzeRamangwana
Pasinei nemabhenefiti ayo, electrocoagulation inosangana nematambudziko akati wandei:
Kushandiswa kweElectrode: Kuzvipira kweanode kunoita kuti ishandiswe zvishoma nezvishoma, zvichida kutsiviwa kana kugadzurwa nguva nenguva.
Kushandiswa Kwesimba: Kunyange hazvo magetsi eDC achibvumira kutonga kwakanyatsojeka, anogona kushandisa simba rakawanda, kunyanya pakushanda kukuru.
Kutarisira Tsvina: Maitiro aya anogadzira tsvina inoda kutarisirwa nekuraswa nemazvo, zvichiwedzera mari yekushandisa.
Tsvagiridzo nebudiriro dzeramangwana zvine chinangwa chekugadzirisa matambudziko aya ne:
Kuvandudza Zvinhu zveElectrode: Kugadzira zvinhu zveelectrode zvinogara kwenguva refu uye zvinoshanda zvakanaka kuderedza kushandiswa uye kuwedzera mashandiro.
Kugadzirisa Kuwanikwa Kwemagetsi: Kushandisa matekiniki epamusoro ekupa magetsi, akadai se pulsed DC, kuderedza kushandiswa kwesimba uye kuvandudza kushanda zvakanaka kwekurapa.
Kuvandudza Kubata Tsvina: Kugadzira nzira dzekuderedza tsvina uye kuikoshesa, dzakadai sekushandura tsvina kuita zvigadzirwa zvinobatsira.
Mukupedzisa, magetsi eDC anoita basa rakakosha mukugadzirisa mvura yakasviba nemagetsi, zvichipa mhinduro inoshanda, isingakuvadzi nharaunda, uye inoshanda pakubvisa tsvina dzakasiyana-siyana. Nekufambira mberi kuri kuitwa uye kugadziriswa, magetsi emagetsi achava nzira inoshanda uye inogara kwenguva refu yekugadzirisa matambudziko epasi rose ekugadzirisa mvura yakasviba.
