Munyika, zvinhu zvese zvine zvazvakanakira nezvazvakaipira. Kufambira mberi kwenharaunda uye kuvandudzwa kwemararamiro evanhu zvinotungamira mukusvibiswa kwezvakatipoteredza. Mvura yakasviba ndeimwe yedambudziko rakadaro. Nekukura nekukurumidza kwemaindasitiri akadai semakemikari epetrochemicals, machira, kugadzira mapepa, mishonga yezvipembenene, mishonga yemishonga, simbi, uye kugadzirwa kwechikafu, kubudiswa kwemvura yakasviba kwakawedzera zvakanyanya pasi rose. Uyezve, mvura yakasviba inowanzo kuve nehuwandu hwakawanda, chepfu yakawanda, munyu wakawanda, uye zvinhu zvine ruvara rwakawanda, zvichiita kuti zviome kuibvisa nekurapa, zvichikonzera kusvibiswa kwakanyanya kwemvura.
Kuti vagadzirise huwandu hwakawanda hwemvura inoraswa mumaindasitiri inogadzirwa zuva nezuva, vanhu vakashandisa nzira dzakasiyana-siyana, vachisanganisa nzira dzemuviri, dzemakemikari, uye dzebhayoloji, pamwe nekushandisa masimba akadai semagetsi, ruzha, chiedza, uye magineti. Chinyorwa chino chinopfupikisa kushandiswa kwe "magetsi" muhunyanzvi hwekurapa mvura hwemagetsi kugadzirisa nyaya iyi.
Tekinoroji yekurapa mvura nemakemikari inoreva maitiro ekusvibisa mvura yakasviba kuburikidza nemaitiro chaiwo emagetsi, maitiro emagetsi, kana maitiro epanyama mukati meimwe reactor yemagetsi, pasi pesimba remaelectrode kana munda wemagetsi wakashandiswa. Masisitimu emagetsi nemidziyo zviri nyore, zvine nhanho diki, zvine mari shoma yekushanda nekugadzirisa, zvinodzivirira kusvibiswa kwechipiri, zvinopa kugona kwakanyanya kudzora maitiro, uye zvinobatsira mukuita otomatiki kwemaindasitiri, zvichizviwanira zita retekinoroji "inochengetedza nharaunda".
Tekinoroji yekurapa mvura nemagetsi inosanganisira nzira dzakasiyana siyana dzakadai se electrocoagulation-electroflotation, electrodialysis, electroadsorption, electro-Fenton, uye electrocatalytic advanced oxidation. Nzira idzi dzakasiyana uye imwe neimwe ine mashandisirwo ayo akakodzera uye nzvimbo dzayo.
Kuonda kwemagetsi-Kuita kuti Electroflotation
Kubatana kwemagetsi, kutaura zvazviri, i electroflotation, sezvo maitiro ekusangana kwemasero anoitika panguva imwe chete nekusangana kwemasero. Nokudaro, inogona kunzi "electrocoagulation-electroflotation."
Nzira iyi inoshandisa magetsi ekunze, ayo anogadzira ma "soluble cations" pa "anode". Ma "cations" aya ane simba rekuonda pa "colloidal pollutions". Panguva imwe chete, huwandu hwakawanda hwegasi rehydrogen rinogadzirwa pa "cathode" pasi pesimba re "voltage", izvo zvinobatsira kuti zvinhu zvakanyungudutswa zvikwire pamusoro. Nenzira iyi, "electrocoagulation" inoita kuti mvura iparadzaniswe uye icheneswe kuburikidza ne "anode coagulation" uye "cathode flotation".
Uchishandisa simbi seanode inonyunguduka (kazhinji aruminiyamu kana iron), maion eAl3+ kana Fe3+ anogadzirwa panguva yeelectrolysis anoshanda se electroactive coagulants. Ma coagulants aya anoshanda nekudzvanya colloidal double layer, kuikanganisa, uye kubatanidza nekubata colloidal particles kuburikidza ne:
Al -3e→ Al3+ kana Fe -3e→ Fe3+
Al3+ + 3H2O → Al(OH)3 + 3H+ kana 4Fe2+ + O2 + 2H2O → 4Fe3+ + 4OH-
Kune rumwe rutivi, electroactive coagulant yakagadzirwa inonzi soluble polymeric hydroxo complexes uye inoshanda seflocculant yekukanda nekukurumidza uye zvinobudirira colloidal suspensions (madonhwe emafuta akanaka uye tsvina yemakanika) mumvura yakasviba uku ichibatanidza nekuibatanidza kuti igadzire ma aggregates makuru, zvichikurumidzisa maitiro ekuparadzanisa. Kune rumwe rutivi, colloids inomanikidzwa pasi pesimba re electrolytes dzakadai sealuminium kana iron salts, zvichikonzera kukanda kuburikidza neCoulombic effect kana adsorption ye coagulants.
Kunyangwe basa remagetsi (nguva yehupenyu) remagetsi anokonzera macoagulants riri maminetsi mashoma chete, anokanganisa zvakanyanya kugona kwe double layer, nokudaro achiita kuti coagulation ive yakasimba pa colloidal particles kana suspended particles. Nekuda kweizvozvo, adsorption yavo uye activity yakakwira zvikuru kupfuura nzira dzemakemikari dzinosanganisira kuwedzera aruminiyamu salt reagents, uye dzinoda huwandu hushoma uye dzine mitengo yakaderera. Electrocoagulation haikanganisirwi nemamiriro ekunze, tembiricha yemvura, kana tsvina yemuviri, uye haiitirwe side reactions ne aruminiyamu salts uye water hydroxides. Saka, ine pH yakakura yekurapa mvura yakasviba.
Pamusoro pezvo, kuburitswa kwemabubble madiki pamusoro pe cathode kunokurumidza kuroverana nekuparadzaniswa kwe colloids. Kuiswa kwe electro-oxidation zvakananga pamusoro pe anode uye electro-oxidation isina kunanga ye Cl- into active chlorine zvine simba guru re oxidative pazvinhu zvinonyunguduka zve organic uye zvinhu zvisingagadzirisike mumvura. Hydrogen ichangobva kugadzirwa kubva mu cathode ne oxygen kubva mu anode zvine simba guru re redox.
Nekuda kweizvozvo, maitiro emakemikari anoitika mukati me electrochemical reactor akaomarara zvikuru. Mu reactor, maitiro e electrocoagulation, electroflotation, uye electrooxidation zvese zvinoitika panguva imwe chete, zvichishandura uye kubvisa colloids yakanyungudutswa uye tsvina yakamiswa mumvura kuburikidza nekugwinya, kuyerera, uye oxidation.
