Teknụzụ ọgwụgwọ mmiri elektrọnik gụnyere usoro dị iche iche dị ka electrocoagulation-electroflotation, electrodialysis, electroadsorption, electro-Fenton, na electrocatalytic oxidation Advanced. Usoro ndị a dị iche iche na nke ọ bụla nwere ngwa na ngalaba kwesịrị ekwesị nke ya.

Electrocoagulation - Electroflotation

Electrocoagulation, n'ezie, bụ electroflotation, dị ka coagulation usoro na-eme n'otu oge na flotation. Ya mere, enwere ike ịkpọ ya ọnụ dị ka "electrocoagulation-electroflotation."

Usoro a na-adabere na ntinye nke voltaji eletrik dị n'èzí, nke na-emepụta cations soluble na anode. cations ndị a nwere mmetụta coagulating na colloidal pollutants. N'otu oge ahụ, a na-emepụta nnukwu hydrogen gas na cathode n'okpuru mmetụta nke voltaji, nke na-enyere ihe ndị a na-agbagharị agbago na-ebili n'elu. N'ụzọ dị otú a, electrocoagulation na-enweta nkewa nke mmetọ na ịdị ọcha nke mmiri site na anode coagulation na cathode flotation.

Iji metal dị ka anode soluble (nke aluminom ma ọ bụ ígwè), ion Al3 + ma ọ bụ Fe3 + emepụtara n'oge electrolysis na-eje ozi dị ka coagulant electroactive. Ndị a coagulant na-arụ ọrụ site na ịpịkọta oyi akwa colloidal okpukpu abụọ, na-eme ka ọ ghara ịdị ike, na ijikọ na ijide ụmụ irighiri ihe colloidal site na:

Al -3e → Al3+ ma ọ bụ Fe -3e → Fe3+

Al3+ + 3H2O → Al(OH)3 + 3H+ ma ọ bụ 4Fe2+ + O2 + 2H2O → 4Fe3+ + 4OH-

N'otu aka ahụ, a na-akpọ electroactive coagulant M (OH) n dị ka ogige polymeric hydroxo soluble ma na-arụ ọrụ dị ka flocculant na-agbakọta ngwa ngwa na n'ụzọ dị irè colloidal suspensions (ezigbo ụmụ irighiri mmanụ na ihe adịghị arụ ọrụ) n'ime mmiri na-ekpofu mmiri mgbe ị na-ejikọta ma jikọta ha ka ha mepụta. nnukwu mkpokọta, na-eme ka usoro nkewa ahụ dịkwuo ngwa. N'aka nke ọzọ, a na-ejikọta colloid n'okpuru mmetụta nke electrolytes dị ka aluminom ma ọ bụ nnu ígwè, na-eduga na coagulation site na mmetụta Coulombic ma ọ bụ adsorption nke coagulant.

Ọ bụ ezie na ọrụ electrochemical (ndụ ndụ) nke coagulant electroactive bụ nanị nkeji ole na ole, ha na-emetụta ike nke okpukpu abụọ, si otú a na-enwe mmetụta coagulation siri ike na ụmụ irighiri colloidal ma ọ bụ kwụsịtụrụ. N'ihi ya, ikike mgbasa ozi ha na ọrụ ha dị elu karịa usoro kemịkalụ gụnyere mgbakwunye nke reagents nnu nnu, ha na-achọkwa obere ego ma nwee ọnụ ahịa dị ala. Electrocoagulation adịghị emetụta ọnọdụ gburugburu ebe obibi, okpomọkụ mmiri, ma ọ bụ adịghị ọcha nke ihe ndị dị ndụ, ọ dịghịkwa enwe mmeghachi omume n'akụkụ ya na nnu aluminum na mmiri hydroxides. Ya mere, ọ nwere oke pH dị obosara maka ịgwọ mmiri mkpofu.

Na mgbakwunye, mwepụta nke obere afụ n'elu cathode na-eme ka nkukota na nkewa nke colloid dịkwuo ngwa. Ngwakọta elektrọn-oxidation ozugbo na elu anode yana electro-oxidation na-apụtaghị ìhè nke Cl-n'ime chlorine na-arụ ọrụ nwere ikike oxidative siri ike na ihe ndị nwere ike soluble na ihe inorganic na-emebi emebi na mmiri. Mmiri hydrogen ọhụrụ sitere na cathode na oxygen sitere na anode nwere ikike redox siri ike.

N'ihi ya, usoro kemịkalụ na-eme n'ime reactor electrochemical dị oke mgbagwoju anya. Na reactor, electrocoagulation, electroflotation, na electrooxidation usoro niile na-eme n'otu oge, na-agbanwe nke ọma ma na-ewepụ ma colloid agbazere na kwụsịtụrụ mmetọ n'ime mmiri site na coagulation, flotation, na oxidation.
