Tannery Wastewater Treatment Technology ndi Njira

Mkhalidwe wamakampani ndi mawonekedwe amadzi otayira zikopa
M'moyo watsiku ndi tsiku, zinthu zachikopa monga matumba, nsapato zachikopa, zovala zachikopa, sofa zachikopa, etc. M’zaka zaposachedwapa, ntchito yachikopa yakula mofulumira. Panthawi imodzimodziyo, kutayira kwa madzi onyansa a chikopa pang'onopang'ono kwakhala chimodzi mwazinthu zofunika kwambiri zowononga mafakitale.
Kuwotcha nthawi zambiri kumaphatikizapo magawo atatu okonzekera, kupukuta ndi kumaliza. Mu gawo lokonzekera musanatenthedwe, zonyansa makamaka zimachokera ku kutsuka, kuthirira, kuchotsa tsitsi, kuyika laimu, kuchotsa, kufewetsa ndi kuchotsa mafuta; zoipitsa zazikulu monga organic zinyalala, inorganic zinyalala ndi organic mankhwala. Madzi otayira pagawo lotenthetsa khungu makamaka amachokera kuchapa, pickling, ndi kufufuta; zoipitsa zazikulu ndi mchere wa inorganic ndi heavy metal chromium. Madzi otayira mu gawo lomaliza makamaka amachokera kuchapa, kufinya, utoto, mafuta odzola ndi kuchotsa zinyalala, ndi zina zotero. Zowonongeka zimaphatikizapo utoto, mafuta ndi organic compounds. Chifukwa chake, madzi otayira zikopa ali ndi mawonekedwe a kuchuluka kwamadzi ambiri, kusinthasintha kwakukulu kwamadzi ndi kuchuluka kwa madzi, kuchuluka kwa kuipitsa kwambiri, kuchuluka kwa alkalinity, chroma yayikulu, zolimba zoyimitsidwa, kusinthika kwabwino kwachilengedwe, ndi zina zambiri, ndipo ali ndi kawopsedwe kena.
Madzi otayira okhala ndi sulufule: Kuthira madzi otayira opangidwa ndi phulusa la alkali dehairing potentha ndi kuchapa molingana ndi madzi otayira;
Kuthira madzi oipa: Pochotsa mafuta otenthetsa khungu ndi kukonza ubweya, madzi otayirawo amapangidwa pothira zikopa zaiwisi ndi mafuta ndi surfactant ndi madzi anyansi ofanana ndi ochapira.
Madzi otayira okhala ndi chromium: zakumwa zotayidwa za chrome zomwe zimapangidwira pakuwotcha kwa chrome ndi njira zowotchera ma chrome, ndi madzi otayira ofanana pochapa.
Madzi otayira okwanira: mawu wamba amadzi otayira osiyanasiyana opangidwa ndi mabizinesi otenthetsa ndi ubweya waubweya kapena malo opangira zinthu zapakati, ndipo amatayidwa mwachindunji kapena m'njira zina kumapulojekiti oyeretsera madzi oipa (monga kupanga madzi onyansa, zimbudzi zapanyumba m'mafakitale).
