Munyika, zvinhu zvose zvine zvazvakanakira nezvazvakaipira. Kufambira mberi kwevanhu uye kuvandudzwa kwemararamiro evanhu zvinotungamirira kukusvibiswa kwezvakatipoteredza. Mvura yakasviba ndeimwe nyaya yakadaro. Nekukurumidza kusimudzira maindasitiri akadai sepetrochemicals, machira, kugadzira mapepa, mishonga yekuuraya zvipembenene, mishonga, simbi, uye kugadzirwa kwechikafu, kuburitswa kwemvura yetsvina kwakawedzera zvakanyanya pasi rese. Uyezve, mvura yetsvina inowanzova nehupamhi hwepamusoro, huturu hwepamusoro, salinity yakawanda, uye zvikamu zvemavara akakwirira, zvichiita kuti zviome kuderedza uye kurapa, zvichiita kuti kusvibiswa kwemvura kwakanyanya.
Kugadzirisa kuwanda kwemvura inoraswa mumaindasitiri inogadzirwa zuva nezuva, vanhu vakashandisa nzira dzakasiyana-siyana, kubatanidza maitiro emuviri, makemikari, uye zvipenyu, pamwe nekushandisa masimba akadai semagetsi, ruzha, chiedza, uye magineti. Ichi chinyorwa chinopfupisa kushandiswa kwe "magetsi" mune electrochemical mvura kurapwa tekinoroji kugadzirisa nyaya iyi.
Electrochemical water treatment tekinoroji inoreva maitiro ekusvibisa zvinosvibisa mumvura yetsvina kuburikidza nemaitiro emagetsi emagetsi, maitiro emagetsi, kana maitiro emuviri mukati meimwe electrochemical reactor, pasi pesimba remagetsi kana nzvimbo yemagetsi yakaiswa. Electrochemical system nemidziyo zviri nyore, zvinotora diki tsoka, zvine mutengo wakaderera wekushandisa nekugadzirisa, zvinodzivirira kudzivirira kusvibiswa kwechipiri, zvinopa kudzoreka kwakanyanya kwekuitika, uye zvinogoneka kumaindasitiri otomatiki, zvichivawanira zita rekuti "hushamwari kwezvakatipoteredza" tekinoroji.
Electrochemical water treatment tekinoroji inosanganisira akasiyana matekiniki akadai se electrocoagulation-electroflotation, electrodialysis, electroadsorption, electro-Fenton, uye electrocatalytic advanced oxidation. Aya matekiniki akasiyana uye imwe neimwe ine yayo yakakodzera maapplication uye madomasi.
Electrocoagulation-Electroflotation
Electrocoagulation, chokwadi, inonzi electroflotation, sezvo iyo coagulation process inoitika panguva imwe chete nekuyerera. Nokudaro, inogona kunzi pamwe chete se "electrocoagulation-electroflotation."
Iyi nzira inotsamira pakushandiswa kwemagetsi ekunze emagetsi, ayo anogadzira soluble cations pane anode. Aya ma cations ane coagulating mhedzisiro pane colloidal zvinosvibisa. Panguva imwe chete, huwandu hwakakura hwehydrogen gasi hunogadzirwa pane cathode pasi pesimba remhepo, iyo inobatsira iyo flocculated zvinhu kukwira kumusoro. Nenzira iyi, electrocoagulation inobudirira kuparadzaniswa kwezvinosvibisa uye kucheneswa kwemvura kuburikidza neanode coagulation uye cathode flotation.
Kushandisa simbi seanode inonyungudika (kazhinji aruminiyamu kana simbi), iyo Al3+ kana Fe3+ ions inogadzirwa panguva ye electrolysis inoshanda semagetsi emagetsi. Aya macoagulants anoshanda nekudzvanya iyo colloidal yakapetwa kaviri layer, ichiikanganisa, uye bhiriji uye nekutapa colloidal particles kuburikidza:
Al -3e→ Al3+ kana Fe -3e→ Fe3+
Al3+ + 3H2O → Al(OH)3 + 3H+ kana 4Fe2+ + O2 + 2H2O → 4Fe3+ + 4OH-
Kune rimwe divi, iyo yakaumbwa electroactive coagulant M (OH)n inonzi soluble polymeric hydroxo complexes uye inoita senge inoyerera nekukurumidza uye zvinobudirira kugadzika colloidal suspensions (madonhwe emafuta akanaka uye kusvibiswa kwemuchina) mumvura ine tsvina paunenge uchibatanidza nekubatanidza kuti aumbe. akakura aggregates, kukurumidza kupatsanurwa. Kune rimwe divi, colloids inomanikidzwa pasi pesimba re electrolytes senge aluminium kana iron munyu, zvichitungamira ku coagulation kuburikidza neCoulombic mhedzisiro kana adsorption ye coagulants.
Kunyange zvazvo kushandiswa kwe electrochemical (hupenyu hurefu) hwe electroactive coagulants inongova maminetsi mashomanana, zvinonyanya kukanganisa huviri hwehuviri hunogona, zvichiita kuti zvive nemigumisiro yakasimba yekubatanidza pazvikamu zvecolloidal kana zvidimbu zvakamiswa. Nekuda kweizvozvo, yavo adsorption kugona uye kuita kwakakwira zvakanyanya kupfuura nzira dzemakemikari dzinosanganisira kuwedzera kwealuminium munyu reagents, uye inoda mari shoma uye ine mutengo wakaderera. Electrocoagulation haikanganisike nemamiriro ezvakatipoteredza, tembiricha yemvura, kana kusvibiswa kwebiological, uye haiitirwe nearuminiyamu munyu uye mvura hydroxides. Naizvozvo, ine yakafara pH renji yekurapa tsvina.
Pamusoro pezvo, kuburitswa kwemabhururu madiki pane cathode pamusoro kunowedzera kudhumhana uye kupatsanurwa kwemacolloid. Iyo yakananga electro-oxidation pamusoro peanode uye isina kunanga electro-oxidation yeCl-inoshanda chlorine ine yakasimba oxidative kugona pane soluble organic zvinhu uye reducible inorganic zvinhu mumvura. Iyo ichangobva kugadzirwa haidrojeni kubva kune cathode uye oksijeni kubva kune anode ine simba redox kugona.
Nekuda kweizvozvo, maitiro emakemikari anoitika mukati meiyo electrochemical reactor yakaoma zvakanyanya. Mu reactor, electrocoagulation, electroflotation, uye electrooxidation maitiro ese anoitika panguva imwe chete, zvinobudirira kushandura uye kubvisa zvese zvakanyungudutswa colloid uye yakamiswa zvinosvibisa mumvura kuburikidza ne coagulation, flotation, uye oxidation.
