Electrocoagulation (EC) chirongwa chinoshandisa magetsi ekubvisa zvinosvibisa mumvura yetsvina. Inosanganisira kushandiswa kwemagetsi eDC kunyungudutsa maelectrode echibairo, ayo anobva aburitsa maion simbi anobatana nezvinosvibisa. Iyi nzira yakawana mukurumbira nekuda kwekushanda kwayo, hushamwari hwezvakatipoteredza, uye kuita zvakasiyana-siyana mukurapa marudzi akasiyana-siyana emvura yakasviba.
Nheyo dzeElectrocoagulation
Mu electrocoagulation, magetsi emagetsi anopfuudzwa kuburikidza nesimbi electrode yakanyudzwa mumvura yakasviba. Iyo anode (positive electrode) inonyungudika, ichiburitsa simbi cations sealuminium kana simbi mumvura. Aya maion esimbi anopindirana nezvinosvibisa mumvura, achigadzira insoluble hydroxides inoungana uye inogona kubviswa nyore. Iyo cathode (negative electrode) inogadzira hydrogen gasi, iyo inobatsira mukuyangarara iyo yakagadzika zvimedu kusvika pamusoro kuti skimming.
Iyo yese process inogona kupfupikiswa mumatanho anotevera:
Electrolysis: dc simba rekushandisa rinoiswa kune electrode, zvichiita kuti anode iparare uye isunungure simbi ions.
Coagulation: Ioni dzesimbi dzakaburitswa dzinoita kuti kupomerwa kwezvimedu zvakamiswa uye zvakanyungudutswa zvinosvibisa, zvichitungamira pakuumbwa kweakakura akaunganidzwa.
Flotation: Mabhuru eHydrogen gasi anogadzirwa pacathode anonamatira kune akaunganidzwa, achiita kuti ayangamire pamusoro.
Kuparadzaniswa: Iyo sludge inoyangarara inobviswa nekusvetuka, nepo yakagadzika sludge inounganidzwa kubva pasi.
Zvakanakira zveDC Power Supply muElectrocoagulation
Kunyatsoita: dc magetsi emagetsi anobvumira kutonga kwakaringana pamusoro peyazvino uye magetsi akaiswa, achikwenenzvera kunyungudika kwemagetsi uye kuve nechokwadi chekubatana kwezvinosvibisa.
Kureruka: Iyo yekuseta ye electrocoagulation uchishandisa DC magetsi emagetsi ari nyore, anosanganisira magetsi emagetsi, maelectrodes, uye kamuri yekuita.
Kushamwaridzana Kwenzvimbo: Kusiyana nemakemikari coagulation, electrocoagulation haidi kuwedzerwa kwemakemikari ekunze, kuderedza njodzi yekusvibiswa kwechipiri.
Versatility: EC inogona kurapa zvakasiyana-siyana zvinosvibisa, zvinosanganisira heavy metals, organic compounds, zvakamiswa zvakasimba, uye kunyange utachiona.
Zvishandiso zveElectrocoagulation muWastewater Treatment
Industrial Wastewater: Electrocoagulation inoshanda zvakanyanya mukurapa tsvina yemumaindasitiri ine heavy metals, dhayi, oiri, uye zvimwe zvinosvibisa zvinonetsa. Maindasitiri akadai semachira, electroplating, uye mishonga inobatsirwa nekugona kweEC kubvisa zvinhu zvine muchetura uye kuderedza kudiwa kwemakemikari okisijeni (COD).
Municipal Wastewater: EC inogona kushandiswa senzira yepuraimari kana yechipiri yekurapa yemvura yetsvina yemanisipala, ichibatsira kubvisa yakamiswa yakasimba, phosphates, uye utachiona. Inosimudzira kunaka kwese kwemvura yakacheneswa, ichiita kuti ive yakakodzera kuburitswa kana kushandiswa zvakare.
Agricultural Runoff: EC inokwanisa kurapa mvura yekurima ine mishonga yekuuraya zvipembenene, fetereza, uye organic matter. Ichi chishandiso chinobatsira mukudzikisa kukanganiswa kwemabasa ekurima pamitumbi yemvura iri pedyo.
Kurapa kweStormwater: EC inogona kuiswa kumvura inoyerera yemvura inoyerera kubvisa marara, simbi inorema, uye zvimwe zvinosvibisa, zvichivadzivirira kuti vasapinda mumvura yakasikwa.
Operational Parameters uye Optimization
Kubudirira kwe electrocoagulation kunoenderana neanoverengeka ma paramita ekushanda, anosanganisira:
Current Density: Huwandu hwemazuva ano hunoshandiswa pane imwe unit nzvimbo ye electrode inokanganisa chiyero chekuburitswa kwesimbi ion uye kugona kwese kwekuita. Kuwedzerwa kwepamusoro ikozvino kunogona kuwedzera kushanda kwekurapa asi kunogona kutungamira kune yakanyanya kushandiswa kwesimba uye kupfeka electrode.
Electrode Material: Sarudzo ye electrode zvinhu (kazhinji aruminiyamu kana simbi) inopesvedzera mhando uye kugona kwe coagulation. Zvinhu zvakasiyana-siyana zvinosarudzwa zvichibva pane zvakasvibiswa zvakasvibiswa zviripo mumvura yakasvibiswa.
pH: Iyo pH yemvura yakasviba inokanganisa kunyungudika uye kuumbwa kwesimbi hydroxides. Optimal pH mazinga anovimbisa yakanyanya coagulation kushanda uye kugadzikana kweakaumbwa akaunganidzwa.
Electrode Configuration: Kurongeka uye nzvimbo yemagetsi inokanganisa kugoverwa kwendima yemagetsi uye kufanana kwemaitiro ekurapwa. Kugadziriswa kwakakodzera kunowedzera kusangana pakati pesimbi ions uye zvinosvibisa.
Nguva Yekuita: Nguva ye electrocoagulation inokanganisa huwandu hwekubvisa tsvina. Yakakwana yekuita nguva inovimbisa kukwana kwakakwana uye kuparadzaniswa kwezvinosvibisa.
Matambudziko uye Nhungamiro Yeramangwana
Kunyangwe zvakanakira, electrocoagulation inotarisana nemamwe matambudziko:
Electrode Consumption: Chibairo chechimiro cheanode chinotungamira kukushandisa kwayo zvishoma nezvishoma, ichida kutsiva nguva nenguva kana kuvandudzwa.
Kushandiswa Kwemagetsi: Nepo magetsi eDC achibvumira kunyatso kudzora, anogona kunge achiwedzera simba, kunyanya kumabasa makuru.
Sludge Management: Iyo nzira inogadzira sludge inoda kuchengetedzwa nemazvo uye kuraswa, ichiwedzera kumari yekushandisa.
Tsvagiridzo yeramangwana nebudiriro zvinovavarira kugadzirisa matambudziko aya ne:
Kuvandudza Zvishandiso zveElectrode: Kugadzira zvinhu zvinogara uye zvinoshanda zve electrode kuderedza kushandiswa uye kuwedzera kushanda.
Kuvandudza Simba reKugovera: Kushandisa nzira dzepamusoro dzekugovera magetsi, senge pulsed DC, kuderedza kushandiswa kwesimba uye kugadzirisa kurapa kwakanaka.
Kuvandudza Sludge Kubata: Kuvandudza nzira dzekudzikisa matope uye valorization, sekushandura sludge kuita zvigadzirwa zvinobatsira.
Mukupedzisa, magetsi eDC anoita basa rakakosha mu electrocoagulation yekuchenesa mvura yetsvina, ichipa inoshanda, ine hushamwari kwezvakatipoteredza, uye inogoneka mhinduro yekubvisa zvakasiyana zvinosvibisa. Nekuenderera mberi nekuenderera mberi uye optimizations, electrocoagulation yagadzirira kuve yakatonyanya kushanda uye yakatsiga nzira yekugadzirisa matambudziko epasi rose ekugadzirisa tsvina.
