Madzi otayira m'mafakitale ndi madzi otayira, zinyalala ndi zinyalala zomwe zimapangidwa popanga mafakitale, nthawi zambiri zimakhala ndi zinthu zopangira mafakitale, zinthu zina ndi zoipitsa zomwe zimapangidwa popanga mafakitale. Kusamalira madzi otayira m'mafakitale kumatanthauza njira yosamalira bwino madzi omwe amagwiritsidwa ntchito popanga mafakitale popanga kapena kutulutsa madzi kuchokera ku fakitale, zomwe zimatha kuchiza bwino madzi otayira omwe amapangidwa m'mafakitale ndikuchepetsa kuipitsa chilengedwe. Monga chimodzi mwazofunikira pakulamulira chilengedwe, kusamalira madzi otayira m'mafakitale kuli ndi mawonekedwe osavulaza, ochepetsedwa komanso ogwirizana ndi anthu, ndipo amagwiritsidwa ntchito kwambiri mu mankhwala, kusindikiza ndi kupaka utoto, mankhwala, zitsulo ndi madera ena amafakitale. Kusamalira madzi otayira m'mafakitale kumatenga njira zosiyanasiyana zochizira malinga ndi mtundu wa kuipitsa m'madzi otayira. Malinga ndi njira yake yochizira, imatha kuchiritsidwa
Yogawidwa m'njira zochizira thupi, njira yochizira mankhwala, njira yochizira physicochemical ndi njira yochizira matenda achilengedwe. Pakati pawo, matope oyambitsidwa mu njira yochizira matenda achilengedwe. Njirayi ili ndi mphamvu zambiri zosinthira mankhwala ndipo imakhudza bwino kuchiza zoipitsa m'madzi otayira achilengedwe m'mafakitale. Pakadali pano ndiyo njira yochizira madzi otayira a m'mafakitale yomwe imagwiritsidwa ntchito kwambiri.
Kuyambitsidwa kwa mfundo zotsogolera chitukuko cha kusunga mphamvu ndi kuteteza chilengedwe m'makampani osamalira madzi otayika m'mafakitale Monga chimodzi mwa zinthu zofunika kwambiri pa kayendetsedwe ka chilengedwe, kukonza madzi otayika m'mafakitale kwakhala ndi gawo lofunika kwambiri pakupanga mafakitale. Mu Okutobala 2010, Bungwe la Boma la China mu "Chisankho Chofulumira Kulima ndi Kupititsa patsogolo Makampani Otukuka Mwachangu" linapereka lingaliro lakuti kusunga mphamvu ndi kuteteza chilengedwe kuyenera kuonedwa ngati limodzi mwa mafakitale asanu ndi awiri atsopano, kuyang'ana kwambiri pakulimbikitsa zida ndi zinthu zaukadaulo zosunga mphamvu moyenera, ndikukwaniritsa ukadaulo wofunikira m'magawo ofunikira. Kupita patsogolo kudzayendetsa bwino kuchuluka kwa mphamvu zogwiritsidwa ntchito bwino. Mu Epulo 2015, Bungwe la Boma la China linapereka Ndondomeko Yothandizira Kupewa ndi Kulamulira Kuipitsidwa kwa Madzi ("Water Ten"), chomwe ndi chizindikiro choyamba cha kuyang'anira kwa China kukonza madzi m'mafakitale. Mapulani apadera osamalira mafakitale khumi ofunikira monga zitsulo zopanda chitsulo, kusindikiza ndi kupaka utoto, kuphika, ndi kupanga ma API akuyendetsedwa, ndipo kusintha koyera kukuchitika kuti akwaniritse cholinga chokonza kuipitsidwa kwa madzi. Kuphatikiza apo, "Malamulo Khumi a Madzi" adaperekanso njira 238 zamphamvu zowongolera kuipitsa m'madera omwe mafakitale amasonkhana. Zikuoneka kuti ngakhale ikuyang'ana kwambiri kuchepetsa kuchuluka kwa kuipitsa, China imayang'ana kwambiri pakukweza khalidwe la malo okhala madzi komanso kupewa ndi kuwongolera zoopsa zachilengedwe. Mu Okutobala 2017, mu lipoti la 19th National Congress of the Communist Party of China, idafunika kukonza miyezo yotulutsa kuipitsa, kulimbitsa udindo wa oipitsa, ndikukonzanso kuwunika ngongole zachilengedwe, kuwulutsa zambiri mokakamiza, chilango chokhwima ndi machitidwe ena. Zidzakhala ndi gawo lalikulu lotsogolera. Kumbali ina, mu lamulo loteteza zachilengedwe, boma la China lakhazikitsanso mfundo zoyenera. Mu Disembala 2017, Bungwe la Boma la China lidakhazikitsa Malamulo Okhudza Kukhazikitsa Lamulo la Misonkho la Chitetezo cha Zachilengedwe la People's Republic of China, lofuna kuti okhometsa msonkho atulutse madzi oipitsa omwe mtengo wake ndi wotsika kuposa 30.0% ya muyezo wotulutsa kuipitsa womwe umafotokozedwa ndi maboma aboma ndi am'deralo, ndikuchepetsa msonkho wa chitetezo cha chilengedwe ndi 75.0%. Ngati kuchuluka kwa zinthu zodetsa kulibe mphamvu kuposa 50.0% ya muyezo wotulutsira zinthu zodetsa womwe waperekedwa ndi maboma aboma ndi am'deralo, msonkho woteteza chilengedwe udzaperekedwa pamlingo wocheperako wa 50.0%. Pambuyo pokhazikitsa mfundoyi, kusonkhanitsa ndalama zochotsera zinyalala kunathetsedwa, zomwe ndizofunikira kwambiri poteteza ndi kukonza chilengedwe, kuchepetsa kutulutsa zinthu zodetsa, komanso kulimbikitsa chitukuko cha zachilengedwe.
Chitsime: Chojambulidwa ndi Sullivan Institute Ukadaulo wokonza madzi ndi njira yopangira zinthu zikuwonetsa chitukuko chosiyanasiyana. Pansi pa mfundo zabwino za dziko, luso lamakono la China lokonza madzi otayidwa m'mafakitale lakhala likukwera kwambiri, zomwe zalimbikitsa kusintha kwa kuchuluka kwa madzi otayidwa m'mafakitale ku China. Chifukwa cha zovuta za kuipitsa madzi m'mafakitale, izi
N'zovuta kuti ukadaulo umodzi ukwaniritse zomwe mukufuna. Chifukwa chake, makampani opanga madzi otayira m'mafakitale ayenera kuchita kafukufuku wophatikizana m'njira zosiyanasiyana, zowonjezera, komanso zogwirizana pogwiritsa ntchito ukadaulo wathunthu wosamalira madzi, monga kuphatikiza mankhwala ndi thupi. Njira zochizira, njira zochizira mankhwala ndi zamoyo, ndi zina zotero, kuti akwaniritse zolinga zogwira ntchito bwino, kugwiritsa ntchito madzi pang'ono komanso kuteteza chilengedwe. Kumbali ina, mu dongosolo la madzi ozizira lozungulira lomwe lili ndi kuchuluka kwa madzi ogwiritsidwa ntchito, njira yogwiritsira ntchito sikelo imagwiritsidwa ntchito kwambiri, koma chifukwa chakuti phosphorous-based corrosion ndi sikelo yoletsa mu fomula iyi imatha kugwira ntchito ngati michere ya mabakiteriya ndi algae m'madzi, zomwe zimayambitsa kuipitsidwa kwa madzi. Kuchuluka kwa madzi m'madzi ndi kuipitsidwa kwa madzi. Chifukwa chake, ndi kusintha kwa ukadaulo wochizira madzi otayira m'mafakitale ku China, chitukuko cha mankhwala ochizira madzi otsika a phosphorous kapena non-phosphorus, non-nitrogen, biodegradable, multi-functional and environmental treatment chemicals chidzakhala njira yayikulu yofufuzira yochizira madzi otayira m'mafakitale.
Boma la China lapereka mfundo zingapo zoteteza chilengedwe, zomwe zimafuna mabizinesi kapena mabungwe okhudzana ndi mafakitale kuti azilamulira madzi otayidwa m'mafakitale mosamala, zomwe zakhala ndi gawo loletsa kutulutsa madzi otayidwa ndi mabizinesi ndikulimbikitsa kukula kwa kufunikira kwa makampani osamalira madzi otayidwa m'mafakitale. Ndi kupita patsogolo pang'onopang'ono kwa mapulojekiti okhudzana ndi kuyeretsa madzi otayidwa m'mafakitale osiyanasiyana, madera otukuka mafakitale apamwamba, komanso malo osungira zachilengedwe ku China, kukula kwa msika wosamalira madzi otayidwa m'mafakitale ku China kudzapitirirabe kukwera.
Tikupitirizabe kuchita zinthu zatsopano zomwe zimabweretsa chitukuko, Kupereka chithandizo chabwino kwambiri, Kutsatsa ndi kutsatsa kwabwino kwa kasamalidwe, Mbiri ya ngongole zomwe zimakopa ogula pamtengo wokweraChina Cleanwat ChemicalAnionic PAM Polyacrylamide Cationic Polymer Flocculant, Chitosan, Chitosan Powder, mankhwala a madzi akumwa, chochotsera utoto wa madzi, dammac, diallyl dimethyl ammonium chloride, dicyandiamide, dcda, defoamer, antifoam, pac, poly aluminium chloride, polyaluminium, polyelectrolyte, pam, polyacrylamide, polydadmac, pdadmac, polyamine, Ubwino wapamwamba komanso mitengo yampikisano zimapangitsa zinthu zathu kukhala zosangalatsa kwambiri kulikonse m'mawu. Mtengo Wogulitsa China Cationic Polyacrylamide, poliacriramida, anionic polyacrylamides, polyacrylamid, polyacrylamide gel, Cationic Flocculant, Kampani yathu imachirikiza mzimu wa "zatsopano, mgwirizano, kugwira ntchito limodzi ndi kugawana, njira, kupita patsogolo kogwira mtima". Tipatseni mwayi ndipo tidzatsimikizira luso lathu. Ndi thandizo lanu lokoma mtima, tikukhulupirira kuti titha kupanga tsogolo labwino nanu limodzi. Ngati mukufuna chinthu chathu, chonde omasuka kuteroLumikizanani nafezitsanzo zaulere.
Kuchokera ku frostchina.
