Chifukwa chakukula kwachuma komanso kukula kwamatauni, kuchuluka kwa madzi otayira kwakhala vuto lalikulu kwambiri lazachilengedwe. High-concentration madzi zinyalala osati muli zambiri organic zinthu, inorganic zinthu, heavy zitsulo ndi zinthu zina zoipa, ndi ndende yake kuposa kamangidwe mphamvu ya ochiritsira zinyalala malo mankhwala. Chifukwa chake, kuthira madzi otayira kwambiri komanso kutulutsa ndikofunikira kwambiri.
1. Tanthauzo ndi makhalidwe a madzi otayira ochuluka kwambiri
Kuchuluka kwa madzi oipa, nthawi zambiri kumatanthauza madzi oipa omwe ali ndi zinthu zambiri zakuthupi, zitsulo zolemera, zinthu zapoizoni ndi zoopsa ndi zina zowononga. Zomwe zili m'madzi onyansa zimaposa zomwe zili m'madzi onyansa ndipo ndizovuta kuzikonza. Ikhoza kukhala ndi mitundu yosiyanasiyana ya zoipitsa, monga organics, heavy metal, ndi radioactive zinthu. Zina mwa zoipitsa zimatha kukhala ndi zotsatira zolepheretsa tizilombo toyambitsa matenda, zomwe zimakhudza momwe chithandizo chachilengedwe chimakhalira, ndipo zimakhala zovuta kuzichotsa ndi njira zochiritsira zachilengedwe.
2. Zochitika za kupangika kwa madzi onyansa kwambiri
Kupanga mankhwala: Madzi onyansa omwe amapangidwa panthawi yopanga mankhwala nthawi zambiri amakhala ndi zinthu zambiri zakuthupi, zitsulo zolemera ndi zina zowononga.
Makampani opanga mankhwala: Madzi otayira a mankhwala nthawi zambiri amakhala ndi zinthu zambiri, maantibayotiki, ndi zina zambiri, ndipo ndizovuta kuchiritsa.
Makampani opanga utoto ndi nsalu: Madzi otayira opangidwa kuchokera m'mafakitalewa nthawi zambiri amakhala ndi zovuta zambiri kuwononga organic ndi chromaticity.
Electroplating ndi zitsulo: njira ya electroplating ndi zitsulo zidzatulutsa madzi oipa omwe ali ndi zitsulo zolemera ndi zinthu zoopsa.
3. Chimake ukadaulo wa mkulu ndende zonyansa mankhwala chomera
High ndende zimbudzi mankhwala chomera, kawirikawiri mwa thupi kapena mankhwala njira kuchotsa particles lalikulu mu madzi oipa, inaimitsidwa zolimba, etc., kulenga zinthu wotsatira mankhwala. Adzakhalanso kudzera monga Fenton makutidwe ndi okosijeni, ozoni okosijeni ndi zina zapamwamba makutidwe ndi okosijeni luso, kudzera m'badwo wa okosijeni amphamvu adzakhala ovuta kunyoza zinthu organic mu zinthu mosavuta degradable. Metabolism ya tizilombo tating'onoting'ono imagwiritsidwa ntchito kuchotsa zinthu zachilengedwe m'madzi onyansa. Pamadzi otayidwa kwambiri, kuphatikiza njira monga anaerobic ndi aerobic zitha kugwiritsidwa ntchito kukonza chithandizo. Zinthu zosungunuka m'madzi onyansa zitha kuchotsedwanso ndi njira zakuthupi kudzera munjira zolekanitsa nembanemba monga ultrafiltration ndi reverse osmosis. Njira zamakono zothandizira zitsulo zolemera monga mphepo yamkuntho, kusinthana kwa ion ndi ma adsorption amagwiritsidwa ntchito kuchotsa ma ion zitsulo zolemera m'madzi onyansa.
Chifukwa chake, chifukwa cha kuchuluka kwa malo opangira zimbudzi, kuwonetsetsa kuti madzi otayira amakumana ndi muyezo, kusankha koyenera kwa njira yopangira chithandizo, kuwongolera mosamalitsa njira yochizira, kulimbitsa chithandizo chisanachitike, kukhathamiritsa magawo ogwiritsira ntchito komanso kuyesa pafupipafupi komanso kuunika ndikofunikira kwambiri, ngati mavuto apezeka, tengani nthawi yake kuti musinthe.
High ndende mankhwala zimbudzi zonyansa chifukwa cha chikhalidwe chapadera cha khalidwe la madzi ake, pakuti zipangizo ali okhwima luso luso, kufunika kokhala ndi luso mankhwala, zinachitikira polojekiti, komanso lingaliro la zinthu m'deralo, pofuna kuonetsetsa kuti mkulu kuchuluka kwa zida zoyeretsera madzi otayira kuti zikwaniritse miyezo ya utsi. Liding Environmental Protection ndi fakitale yayikulu yazaka khumi mumakampani opangira madzi otayira, okhala ku Jiangsu, omwe akuyenda m'dziko lonselo, moyang'anizana ndi kutsidya kwa nyanja, ndi gulu lolimba laukadaulo wazogulitsa.
