Nheyo yekurapa ozone yemvura yakasviba:
Ozone ine simba rakasimba reoxidation.Mukurapa kwemvura yakasviba, iyo yakasimba oxidation kugona kweozone inoshandiswa.Mushure mekurapa ne ozone, hapana kusvibiswa kwechipiri kana chepfu ne-zvigadzirwa.Kuita pakati peozone nemvura yetsvina kwakaoma zvakanyanya uye kunosanganisira maitiro anotevera: kutanga, ozone gasi mamorekuru anopararira kubva pachikamu chegasi kuenda kunharaunda yakatarisana.Zvadaro, apo kusungirirwa kwezvinogadziriswa muzvikamu zviviri zvinosvika pachiyero chepamusoro pahutano, vanopa mamiriro ekuenzana kwemuviri;mushure mezvo, ozone ichapararira kubva munzvimbo yepakati kusvika kune chikamu chemvura uye inosangana nemakemikari.
Kupararira kwezvigadzirwa zvemaitiro kunotangwa zvichibva pane iyo concentration gradient.Pasi pezviito zvakasiyana-siyana zvebiochemical uye physicochemical, ozone inogona kushandura high-molecular-weight organic matter mumvura ine tsvina kuita zvinhu zvakaderera-molecular-uremu uye kushandura zvinhu zvisiri-reactive kuita zvinhu zvinoshandiswa.Naizvozvo, ozone haideredze zvakanyanya organic zvinhu mumvura ine tsvina, asi inogona kushandisa iyo yakasimba oxidation kugona kushandura chimiro uye zvimiro zve organic zvinosvibisa, uye kushandura yakaoma-ku-kusvibisa kana kureba-inoshatisa organic zvinhu kuita diki-morekuru zvinhu zvinogoneka nyore oxidizable. .
Nheyo yekurapa kweozone yemvura yakasviba inonyanya kutsamira pamamorekuru eozone uye ma hydroxyl radicals anogadzirwa muchikamu chayo chemvura kuti aderedze zvinonhuhwirira zvakaita se phenol, toluene, uye benzene.Nzira yekurapa inogona kuwanikwa nenzira mbiri.
Nzira yekutanga ndeye oxidation yakananga.Nekuda kweiyo nucleophilic uye electrophilic zvimiro, ozone inogona kuita nyore neiyo organic zvinhu mumvura yakaraswa, ichirwisa mapoka anoshanda ezvinosvibisa senge phenols uye anilines, uye kugadzira biodegradable acids.
Yechipiri nzira inosanganisira inokonzeresa chizvarwa che hydroxyl radicals kubva kuO3 mamorekuru, kutanga ketani yekuita iyo isina kunanga inowana oxidation uye kushatiswa kwemhando dzakasiyana dzezvinosvibisa organic, kuwana maindasitiri emarara emarara.
Zvichienderana nezvidzidzo zvakapfuura, kurapwa kweozone kunonyanya kutsamira paozone mamorekuru uye hydroxyl radicals inogadzirwa muchikamu chayo chemvura kusvibisa zvinonhuhwirira zvakaita se phenol, toluene, uye benzene.Naizvozvo, nzira mbiri dzekurapa dziripo: yakananga oxidation, iyo inotora mukana weiyo nucleophilic uye electrophilic zvimiro zve ozone kutanga kuita nezvinosvibisa uye kugadzira biodegradable acids, uye isina kunanga oxidation, iyo inosanganisira catalytic chizvarwa che hydroxyl radicals kubva kuO3 mamorekuru kuti oxidize. uye kuderedza saizi yezvinosvibisa organic, kuwana kurapa kunoshanda kwemvura yetsvina yemaindasitiri.
Iwo chaiwo mashandisirwo emajenareta eozone mukurapwa kwemvura yetsvina anosanganisira mapazi akasiyana ekuchenesa mvura yetsvina senge tsvina yemumba, mapombi etsvina, mvura yetsvina yemumaindasitiri, organic wastewater, machira ekudhinda uye dhayi mvura yetsvina, tsvina yekurapa, mvura yetsvina yemvura, phenol-ine tsvina, mvura yekugadzira mapepa, kuchenesa mvura yetsvina, fekitori yechikafu mvura yetsvina, mishonga fekitori mvura yetsvina, nezvimwe.
Mumunda wekurapwa kwemhando yemvura, majenareta e ozone anogonawo kushandiswa pakurapa mvura yakacheneswa, pombi yekurapa mvura yepombi, mafekitori ezvinwiwa, mvura yekunwa, mvura yemamineral, mvura yakagadziriswa mafekitori ezvekudya, mvura yemuchipatara, mvura yematsime, mvura yepamusoro, mvura yechipiri, uye mvura inoshandiswa patsva.
