Amanzi amdaka amdaka avela kwilitye lokuguba angcolisa indalo. Ke ngoko, amanzi amdaka kufuneka anyangwe ngaphambi kokuba akhutshwe okanye aphinde asebenze kwakhona. I-ozone sisixhobo esomeleleyo kakhulu kwaye sidlala indima ebalulekileyo kunyango lwamanzi amdaka.
Ukuprinta kunye nokudaya amanzi amdaka ngamanzi amdaka avela kwimizi-mveliso ane-chroma enkulu, umxholo ophakamileyo wezinto eziphilayo kunye nokwakheka okuntsonkothileyo. Amanzi aqulathe isixa esikhulu sedayi eseleyo, ialkali, idiyazo, azo, njl., Ekunzima ukuyiphatha. Amanzi amdaka alukiweyo ahlala enyangwa ngokwamanqanaba amathathu:
Okokuqala: unyango lomzimba, olwahlulwe ngentlenga kunye nokucoca igridi;
Okwesibini: unyango lweekhemikhali, ukongeza iiarhente zemichiza ukuphucula umgangatho wamanzi;
Okwesithathu: unyango oluphambili, usebenzisa itekhnoloji ye-ozone oxidation , ukunciphisa ngokufanelekileyo i-COD, amaxabiso e-BOD, kunye nokuphucula kakhulu ukusetyenziswa kwakhona kwamanzi okanye ukuthotyelwa.
Indlela yesicelo seOzone:
I-ozone sisixhobo esomeleleyo, kwaye amandla ayo redox emanzini ayindawo yesibini kuphela kwi-fluorine. Iqhele ukusetyenziswa kunyango lwangaphambili kunye nonyango oluphambili lwamanzi amdaka avela kwimizi-mveliso. Inemisebenzi emininzi kunyango lwamanzi, inzalo, ukucoca ulwakhiwo, ukuphelisa ubushushu, ukususa ukungcoliseka kunye nokubola kwe-oxidative. I-Ozone isetyenziselwa ukutshintsha umbala kunye nokuthotywa kwendalo kunye nokunciphisa amaxabiso e-COD kunye ne-BOD kunyango lokuprinta kunye nokudaya amanzi amdaka.
Xa ujongene ne-chromaticity yokuprinta kunye nokudaya amanzi amdaka, i-ozone oxidation inokuqhekeza iqhina le-divalent yedayi-yokunikela ngedayi okanye i-chromogenic gene yedayi, kwaye kwangaxeshanye itshabalalise i-cyclic compound eyenza iqela le-chromophore, ngaloo ndlela ichaze amanzi amdaka.
I-ozone iyaphendula ngento enzima yokuthotywa kwezinto eziphilayo, etshintsha ityhefu yongcoliseko kunye nokuwohloka kwemichiza. Kwangelo xesha, ukunciphisa i-COD kunye ne-BOD, ukuphucula ngakumbi umgangatho wamanzi. I-Ozone inokudibanisa izinto ezininzi eziphilayo kunye nezinto ezincinci emanzini amdaka, kwaye inciphise amaxabiso ayo e-COD kunye ne-BOD ngaphandle kongcoliseko lwesibini kunye nokubola okulula. Kwangelo xesha, inokuphinda isombulule, ukubulala iintsholongwane kunye nokususa. Isetyenziswe ngokubanzi kunyango oluphambili lonyango lwamanzi amdaka.
