Kodi zomera za mankhwala zimasamalira bwanji madzi otayidwa?

Pali njira zitatu zazikulu:

1. Njira ya mankhwala

Mwachidule, zikutanthauza kuwonjezera mankhwala ku madzi otayira kuti dothi lomwe lili mkati ligwire ntchito bwino komanso kuti lichotsedwe mosavuta.

Njira yolumikizira：TMfundo yogwira ntchito ya njira yolumikizirana ndi kuwonjezera mankhwala m'madzi, zomwe zimapangitsa kuti tinthu tating'onoting'ono tomwe timayimitsidwa tigwirizane ndikupanga ma flocs akuluakulu, kenako n’kukhazikika pansi pogwiritsa ntchito mphamvu yokoka. Njirayi imatha kuchotsa bwino chromaticity, mabakiteriya, ndi zinthu zina zachilengedwe m'madzi. Komabe, mphamvu yake yochizira zinthu zomwe zimasungunuka m'madzi ndi yochepa, ndipo mphamvu yake yochizira imakhudzidwa mosavuta ndi kusinthasintha kwa kutentha kwa madzi ndi pH.

Njira yopangira okosijeni:UMa oxidants (monga chlorine, ozone) amawononga zinthu zapoizoni kukhala zopanda vuto. Ozone ili ndi zotsatira zabwino ndipo siiwononganso, koma mtengo wake ndi wokwera; Chlorine imagwiritsidwa ntchito kwambiri ndipo ndi yoyenera kuchiza madzi otayira okhala ndi phenol ndi cyanide; Mphamvu ya okosijeni wa mpweya ndi yofooka pang'ono ndipo nthawi zambiri imagwiritsidwa ntchito m'madzi otayira kumene zinthu zoipitsa zimasungunuka mosavuta.

Njira yamagetsi: Magetsi amagwiritsidwa ntchito kuti alole zinthu zoipitsa kuti zigwire ntchito pamwamba pa elekitirodi kuti zichotsedwe, ndipo nthawi zina sodium chloride imawonjezedwa kuti iwonjezere mphamvu zake. Njirayi ili ndi mphamvu yabwino yokonza zinthu, koma kuipa kwake n'koonekeratu: kumbali imodzi, imagwiritsa ntchito magetsi ambiri ndipo imakhala ndi ndalama zambiri zogwirira ntchito; Kumbali ina, zinthu zina zingachitikenso panthawiyi, zomwe zimapangitsa kuti pakhale kuipitsidwa kwina.

 

2. Njira Yogwirira Ntchito

Lekanitsani zinthu zodetsedwa ndi madzi pogwiritsa ntchito njira zakuthupi.

Njira yosefera imagwiritsa ntchito zosefera zokhala ndi ma micropores (monga ma microporous filters) kuti zigwire zinthu zolimba zomwe zimapachikidwa m'madzi.

Lamulo lokhazikitsa nthaka ndi kugwiritsa ntchito mphamvu yokoka kuti tinthu tolemera kwambiri tomwe timapachikidwa m'madzi a m'chimbudzi tikhazikike mwachilengedwe pansi pa madzi.

Njira yoyandama mpweya imayambitsa thovu laling'ono kwambiri m'madzi, zomwe zimapangitsa kuti lizimamatira ku tinthu tating'onoting'ono tosafunika ndikupanga thupi loyandama lomwe lili ndi kuchuluka kochepa kuposa madzi. Kenako limakwera pamwamba pa madzi mwa kuyandama ndipo limachotsedwa ndi zida zokokera.

Njirazi ndi zosavuta komanso zosavuta kuzisamalira, koma sizingachotse zinthu zoipitsa zomwe zasungunuka m'madzi ndipo zili ndi malire pakugwiritsa ntchito.

 

3. Ukadaulo wa Photocatalytic oxidation

Pogwiritsa ntchito kuwala kwa ultraviolet ndi zinthu zopangitsa kuti zinthu zisawonongeke (monga hydrogen peroxide), zinthu zodetsa zomwe zimakhala zovuta kuziwononga (monga polychlorinated biphenyls) zimatha kuwonongedwa kwathunthu.

Pali njira yotchedwa 'photocatalytic Fenton', yomwe imatha kupanga zinthu zambiri mwachangu ndikuwola bwino zinthu zachilengedwe pogwiritsa ntchito kuwala ndi ma ayoni achitsulo.

Njira ina ndi kuwonjezera zinthu zomwe zimathandiza kuti munthu azitha kuiwala zinthu (monga titanium dioxide), zomwe zimapanga ma free radicals amphamvu kwambiri pansi pa kuwala, zomwe zimawononga zinthu zoipitsa mpweya kukhala zinthu zopanda vuto monga carbon dioxide ndi madzi. Njirayi ili ndi kuthekera kwakukulu kochizira zinthu zoipitsa mpweya zomwe sizingawononge mpweya.
