Kusindikiza ndi kupaka utoto pamadzi amchere - kugwiritsa ntchito ukadaulo wa ozoni

Madzi otaya opangidwa ndi makina opanga nsalu amaipitsa kwambiri chilengedwe. Chifukwa chake, madzi amdima amafunika kuthandizidwa asanatulutsidwe kapena kugwiritsidwanso ntchito. Ozone ndi cholumikizira champhamvu kwambiri ndipo chimagwira gawo lofunikira pochiza madzi owonongeka.

Kusindikiza ndi kupaka utoto wamadzi ndi madzi ogwiritsira ntchito mafakitale okhala ndi chroma yayikulu, okhutira kwambiri komanso mawonekedwe ake. Madzi amakhalanso ndi utoto wambiri wotsalira, alkalis, diazo, azo, ndi zina zambiri, zomwe ndizovuta kuzigwira. Madzi osungira nsalu nthawi zambiri amachiritsidwa m'magawo atatu:

Choyamba: chithandizo chakuthupi, chosiyanitsidwa ndi matope ndi kusefera kwa gridi;

Chachiwiri: chithandizo chamankhwala, kuwonjezera othandizira mankhwala kuti athetse bwino madzi;

Chachitatu: chithandizo chamankhwala, kugwiritsa ntchito ukadaulo wa okosijeni , amachepetsa bwino COD, mfundo za BOD, ndikuwongolera kugwiritsidwanso ntchito kwa madzi kapena kutsatira.

Makina ogwiritsira ntchito ozoni:

Ozone ndi cholumikizira cholimba, ndipo mphamvu yake ya redox m'madzi ndi yachiwiri pambuyo pa fluorine. Amagwiritsidwa ntchito popanga mankhwalawa ndikupangira mankhwala amadzi ogwiritsidwa ntchito m'mafakitale. Ili ndi ntchito zambiri pochiza madzi, yolera yotseketsa, kuchotsa m'madzi, kusungunula madzi, kutaya madzi ndi kuwonongeka kwa okosijeni. Ozone amagwiritsidwa ntchito potulutsa ndi kunyozetsa zinthu zachilengedwe ndikuchepetsa miyezo ya COD ndi BOD pochotsa ndikusindikiza madzi ogwiritsidwa ntchito.

Polimbana ndi kusinthasintha kwa kusindikiza ndi kupaka utoto wa madzi onyansa, ozoni makutidwe ndi okosijeni amatha kuphwanya mgwirizano wophatikizika wa utoto wopangira utoto kapena chromogenic wa utoto, ndikuwononga nthawi yomweyo zomwe zimapanga gulu la chromophore, potero amasungunula madziwo.

Ozone amakumana ndi zovuta kuwononga zinthu zakuthupi, zomwe zimasintha kawopsedwe ka zoipitsa ndikuwononga kwachilengedwe. Nthawi yomweyo, chepetsani COD ndi BOD, ndikupititsanso patsogolo madzi. Ozone amatha kusungitsa zinthu zambiri zamoyo ndi tizilombo tating'onoting'ono m'madzi owonongeka, ndikuchepetsa mphamvu zake za COD ndi BOD popanda kuipitsa kwachiwiri komanso kuwonongeka kosavuta. Nthawi yomweyo, imatha kuwononganso, kuyimitsa komanso kusungunula. Amagwiritsidwa ntchito kwambiri pochiza bwino madzi akumwa.
