Ndi chitukuko chofulumira cha chitukuko cha mafakitale ndi kukwera kwa mizinda, madzi otayira omwe ali ndi vuto lalikulu lakhala vuto lalikulu kwambiri la chilengedwe. High-concentration madzi zinyalala osati ali kuchuluka kwa zinthu organic, inorganic kanthu, zitsulo zolemera ndi zinthu zina zoipa, komanso ndende yake ndi kutali kamangidwe ndi mankhwala mphamvu ya ochiritsira zinyalala mankhwala malo. Chifukwa chake, kuchuluka kwa mankhwala amadzi onyansa komanso kutulutsa kokhazikika ndikofunikira kwambiri.
1. Tanthauzo ndi makhalidwe a madzi onyansa omwe ali pamwamba kwambiri Kuchuluka kwa madzi oipa, nthawi zambiri kumatanthauza madzi onyansa omwe ali ndi zinthu zambiri zakuthupi, zitsulo zolemera, poizoni ndi zowononga zinthu zina. Zomwe zili m'madzi onyansa zimaposa madzi onse otayira, ndipo ndizovuta kuzikonza. Ikhoza kukhala ndi mitundu yosiyanasiyana ya zoipitsa, monga organic matter, heavy metal, radioactive substances, etc. Zina zoipitsa zimatha kukhala ndi zotsatira zolepheretsa tizilombo toyambitsa matenda komanso zimakhudza zotsatira za mankhwala achilengedwe, zomwe zimakhala zovuta kuchotsa ndi njira zochiritsira zamoyo.
2. Zomwe zimachitika m'badwo wamadzi otayira kwambiri Kupanga Chemical: madzi otayira omwe amapangidwa popanga mankhwala nthawi zambiri amakhala ndi zinthu zambiri zakuthupi, zitsulo zolemera ndi zowononga zina. Makampani opanga mankhwala: Madzi otayira amankhwala nthawi zambiri amakhala ndi zinthu zambiri zakuthupi, maantibayotiki, ndi zina zambiri, zomwe zimakhala zovuta kuchiza. Makampani opanga utoto ndi nsalu: madzi otayira omwe amapangidwa ndi mafakitalewa nthawi zambiri amakhala ndi zinthu zambiri zomwe zimatha kuwonongeka komanso kukula kwake. Electroplating and metallurgy: Madzi otayika okhala ndi zitsulo zolemera ndi zinthu zoopsa amapangidwa panthawi ya electroplating ndi metallurgy.
3. Ukadaulo wapakatikati wamakina opangira madzi otayira kwambiri Zida zopangira madzi otayira, nthawi zambiri kudzera m'njira zakuthupi kapena zamankhwala kuti zichotse tinthu tating'onoting'ono tomwe timayimitsidwa m'madzi otayira, kuti apange zinthu zochitira chithandizo chotsatira. Idzagwiritsanso ntchito matekinoloje apamwamba a okosijeni monga Fenton oxidation, ozoni oxidation, popanga oxidant amphamvu kuti atembenuke zinthu zosagwirizana ndi organic kukhala zinthu zosawonongeka mosavuta. Gwiritsani ntchito kagayidwe kachakudya ka tizilombo toyambitsa matenda kuti muchotse zinthu zomwe zili m'madzi onyansa. Kwa madzi owonongeka kwambiri, njira zophatikizira za anaerobic ndi aerobic zitha kutengedwa kuti zithandizire kukonza bwino. Zinthu za tic zomwe zili m'madzi oyipa zitha kuchotsedwanso ndi njira zakuthupi kudzera muukadaulo wolekanitsa wa membrane monga ultrafiltration ndi reverse osmosis. Kupyolera mu mpweya wamankhwala, kusinthanitsa kwa ion, kutsatsa ndi ukadaulo wina wochotsa zitsulo zolemera, zomwe zimagwiritsidwa ntchito pochotsa ma ion zitsulo zolemera m'madzi onyansa. Chifukwa chake, pazida zopangira zinyalala zapamwamba kwambiri, ndikofunikira kuwonetsetsa kuti zonyansazo zifika pamlingo woyenera, sankhani njira yochizira, kuwongolera mosamalitsa njira yochizira, kulimbikitsa kuyambitsirana, kukhathamiritsa magawo ogwirira ntchito ndikuwunika ndikuwunika pafupipafupi. Ngati mavuto apezeka, chitanipo kanthu kuti musinthe.
Chifukwa cha mtundu wake wamadzi, kuthira kwamadzi otayira kwambiri kumakhala ndi zofunikira zaukadaulo pazida. Iyenera kukhala ndi luso lazopangapanga labwino, luso la polojekiti, komanso lingaliro losintha momwe zinthu ziliri mdera lanu kuti zitsimikizire kuti kutayira kwa zida zoyeretsera madzi oyipa kumakwaniritsa. Jiading kuteteza zachilengedwe ndi fakitale wamkulu mu makampani zimbudzi mankhwala kwa zaka khumi, zochokera m'chigawo Jiangsu, cheza ku dziko lonse, kuyang'ana kunja, ali okhwima mankhwala luso gulu kulamulira khalidwe.
