Umgaqo wonyango lwe-ozone yamanzi amdaka:
Iozone inamandla kakhulu okxidation.Kunyango lwamanzi amdaka, isakhono esinamandla se-oxidation se-ozone sisetyenziswa.Emva kokunyanga nge-ozone, akukho ngcoliseko lwesibini okanye iimveliso ezinobuthi.Indlela yokusabela phakathi kwe-ozone kunye namanzi amdaka inzima kakhulu kwaye ibandakanya ezi nkqubo zilandelayo: okokuqala, iimolekyuli zegesi ye-ozone ziyahlukana ukusuka kwisigaba segesi ukuya kummandla ohlangeneyo.Emva koko, xa ugxininiso lwe-reactants kwizigaba ezimbini lufikelela kwinqanaba elisondeleyo kwi-interface, zibonakalisa isimo sokulingana komzimba;emva koko, i-ozone iya kusasazeka ukusuka kwingingqi ye-interfacial ukuya kwisigaba solwelo kwaye ingene kwi-chemical reaction.
Ukusasazwa kweemveliso zokusabela kuqalwa ngokusekelwe kwi-gradient yoxinaniso.Ngaphantsi kweentshukumo ezahlukeneyo ze-biochemical kunye ne-physicochemical, i-ozone inokuguqula i-high-molecular-weight organic matter kumanzi amdaka ibe zizinto ezinobunzima obuphantsi beemolekyuli kwaye iguqule izinto ezingasebenziyo zibe zizinto ezisebenzayo.Ke ngoko, i-ozone ayinciphisi kakhulu i-organic matter kumanzi amdaka, kodwa inokusebenzisa isakhono sayo esomeleleyo se-oxidation ukutshintsha ulwakhiwo kunye neepropathi zezinto ezingcolisa izinto eziphilayo, kwaye iguqule into enzima-ukuthobisa okanye eyonakalise ixesha elide kwizinto eziphilayo eziziimolekyuli ezincinci ezinokuthi zixutywe ngokulula. .
Umgaqo wonyango lwe-ozone yamanzi amdaka uxhomekeke ikakhulu kwiimolekyuli ze-ozone kunye neeradicals ze-hydroxyl eziveliswe kwisigaba sazo samanzi ukuthobisa iikhompawundi ezinevumba elimnandi ezifana ne-phenol, i-toluene, ne-benzene.Inkqubo yonyango inokufezekiswa ngeendlela ezimbini.
Indlela yokuqala yi-oxidation ethe ngqo.Ngenxa yeempawu zayo ze-nucleophilic kunye ne-electrophilic, i-ozone inokusabela ngokulula kunye ne-organic matter kumanzi amdaka, ihlasela amaqela asebenzayo ezinto ezingcolisayo ezifana ne-phenols kunye ne-anilines, kunye nokuvelisa i-acids biodegradable.
Indlela yesibini ibandakanya ukuveliswa kwe-hydroxyl radicals ukusuka kwi-O3 molecules, ukuqalisa ukusabela kwekhonkco okuphumelela ngokungathanga ngqo kwi-oxidation kunye nokuthotywa kweentlobo ezahlukeneyo zokungcola kwezinto eziphilayo, ukufezekisa unyango lwamanzi amdaka kwimizi-mveliso.
Ngokusekwe kwizifundo ezidlulileyo, unyango lwe-ozone luxhomekeke ikakhulu kwiimolekyuli ze-ozone kunye neeradicals ze-hydroxyl eziveliswe kwisigaba sazo samanzi ukuthobisa iikhompawundi ezinuka kamnandi ezifana ne-phenol, toluene, kunye ne-benzene.Ngoko ke, kukho iindlela ezimbini zonyango: i-oxidation ethe ngqo, ethatha inzuzo ye-nucleophilic kunye ne-electrophilic properties ye-ozone ukuqalisa ukusabela kunye nokungcola kunye nokuvelisa i-acids biodegradable, kunye ne-oxidation engathanga ngqo, ebandakanya isizukulwana se-catalytic ye-hydroxyl radicals ukusuka kwi-molecule ye-O3 ukuya kwi-oxidize. kunye nokunciphisa ubungakanani bezinto ezingcolisayo eziphilayo, ukufikelela kunyango olusebenzayo lwamanzi amdaka emizi-mveliso.
Usetyenziso olukhethekileyo lweejeneretha ze-ozone kunyango lwamanzi amdaka lubandakanya amasebe ahlukeneyo okucocwa kwamanzi amdaka anje ngogutyulo lwasekhaya, amaziko okucoca amanzi amdaka, amanzi amdaka avela kwimizi-mveliso, amanzi amdaka endalo, ukuprintwa kwelaphu kunye nokudaya amanzi amdaka, amanzi amdaka ezonyango, amanzi amdaka aselwandle, amanzi amdaka aqulathe i-phenol, amanzi amdaka enziwe ngamaphepha, ukutshisa amanzi amdaka, amanzi amdaka efektri yokutya, amanzi amdaka emizi-mveliso yoxubo, njl.njl.
Kwintsimi yonyango lomgangatho wamanzi, iijenereyitha ze-ozone zingasetyenziselwa unyango lwamanzi ahlambulukileyo, izityalo zokucoca amanzi epompo, iifektri zesiselo, amanzi okusela, amanzi amaminerali, amanzi acutshungulwayo kwiifektri zokutya, amanzi esibhedlele, amanzi aphilileyo, amanzi angaphezulu, unikezelo lwamanzi lwesibini, kunye namanzi asetyenziswe ngokutsha.
