Njira zopangira madzi akumwa pagulu zimagwiritsa ntchito njira zosiyanasiyana zopangira madzi kuti apatse madera awo madzi akumwa abwino.Makina amadzi am'madzi nthawi zambiri amagwiritsa ntchito njira zingapo zochizira madzi, kuphatikiza ma coagulation, flocculation, sedimentation, kusefera ndi kupha tizilombo.
4 Njira Zina Zothetsera Madzi m'dera lanu
1.Coagulation ndi Flocculation
Mu coagulation, mankhwala abwino nayiti monga aluminiyamu sulphate, polyaluminium kolorayidi kapena ferric sulphate amalowetsedwa m'madzi kuti neutralize mlandu zoipa zimene zolimba, kuphatikizapo dothi, dongo, ndi kusungunuka particles organic.Pambuyo pochepetsa mtengowo, tinthu tating'ono tating'ono totchedwa microflocs timapangidwa kuchokera kumangiriza ang'onoang'ono ndi mankhwala owonjezera.
Pambuyo pa coagulation, kusanganikirana kofatsa komwe kumadziwika kuti flocculation kumachitika, kumapangitsa kuti ma microflocs agundane wina ndi mnzake ndikulumikizana kuti apange tinthu tating'onoting'ono tooneka.Izi particles, otchedwa flocs, kupitiriza kukula kukula ndi zina kusanganikirana ndi kufika akadakwanitsira kukula ndi mphamvu, kukonzekera iwo kwa siteji yotsatira mu ndondomekoyi.
Gawo lachiwiri limachitika pamene zinthu zomwe zaimitsidwa ndi tizilombo toyambitsa matenda zimakhazikika pansi pa chidebe.Madziwo akakhala nthawi yayitali osasokonezeka, zolimba zambiri zimagonja ku mphamvu yokoka ndikugwera pansi pa chidebe.Coagulation imapangitsa kuti sedimentation ikhale yogwira mtima chifukwa imapangitsa kuti tinthu ting'onoting'ono tizikhala zazikulu komanso zolemera, zomwe zimapangitsa kuti zimire mofulumira.Kuti pakhale madzi ammudzi, kuthira madzi kumayenera kuchitika mosalekeza komanso m'mabeseni akuluakulu a matope.Ntchito yosavuta, yotsika mtengo iyi ndi gawo lofunikira lachidziwitso chisanadze musanayambe kusefera ndi kupha tizilombo.
3. Sefa
Panthawiyi, tinthu tating'ono ta floc takhazikika pansi pa madzi ndipo madzi omveka bwino ndi okonzeka kuthandizidwa.Kusefedwa ndikofunikira chifukwa cha tinthu tating'onoting'ono, tosungunuka zomwe zikadalipo m'madzi omveka bwino, zomwe zimaphatikizapo fumbi, majeremusi, mankhwala, ma virus, ndi mabakiteriya.
Posefera, madzi amadutsa mu tinthu tating'onoting'ono tosiyanasiyana kukula ndi kapangidwe.Zinthu zomwe zimagwiritsidwa ntchito kwambiri ndi mchenga, miyala, ndi makala.Kusefedwa kwa mchenga pang'onopang'ono kwagwiritsidwa ntchito kwa zaka zoposa 150, ndi mbiri yabwino yochotsa mabakiteriya omwe amayambitsa matenda a m'mimba.Kusefedwa kwa mchenga pang'onopang'ono kumaphatikiza njira zamoyo, zakuthupi, ndi zamankhwala mu sitepe imodzi.Kumbali ina, kusefa mchenga mwachangu ndi gawo loyeretsa thupi.Ndizovuta komanso zovuta, zimagwiritsidwa ntchito m'mayiko otukuka omwe ali ndi ndalama zokwanira zochizira madzi ambiri.Kusefera mchenga mwachangu ndi njira yotsika mtengo poyerekeza ndi zosankha zina, zomwe zimafuna mapampu oyendetsedwa ndi mphamvu, kuyeretsa nthawi zonse, kuwongolera kuthamanga, ntchito yaluso, ndi mphamvu zopitilira.
4. Kupha tizilombo toyambitsa matenda
Gawo lomaliza la ntchito yoyeretsera madzi ammudzi ndikuwonjezera mankhwala ophera tizilombo monga chlorine kapena chloramine m'madzi.Chlorine yakhala ikugwiritsidwa ntchito kuyambira kumapeto kwa zaka za m'ma 1800.Mtundu wa klorini womwe umagwiritsidwa ntchito pochiza madzi ndi monochloramine.Izi ndizosiyana ndi mtundu womwe ungawononge mpweya wamkati wamkati kuzungulira maiwe osambira.Chotsatira chachikulu cha njira yophera tizilombo toyambitsa matenda ndikutulutsa oxidize ndikuchotsa zinthu zachilengedwe, zomwe zimalepheretsa kufalikira kwa majeremusi, ma virus, ndi mabakiteriya omwe angakhalebe m'madzi akumwa.Kupha tizilombo toyambitsa matenda kumatetezanso madzi ku majeremusi omwe angatengedwe ndi tizilombo tomwe timawagawira pamene amapita ku nyumba, masukulu, mabizinesi ndi malo ena.
"Kukhulupirika, Kupanga Zinthu, Kulimba, Kuchita Bwino" ndikutsatira kwanthawi yayitali kwa kampani yathu ku lingaliroli, kupindula limodzi ndi kupindula limodzi ndi ogula, mankhwala opangira zinyalala ku China / mankhwala oyeretsa madzi ku China, kampani yathu yapanga zida zodziwika bwino, zopanga ndi A. gulu lodalirika limapanga ogula ndi mfundo yopambana.
China Wholesale China PAM,cationic polyacrylamide, ndi kuphatikizika kwa chuma cha padziko lonse kumabweretsa zovuta ndi mwayi ku makampani opanga mankhwala ochizira zimbudzi, kampani yathu imatsatira mzimu wogwirira ntchito limodzi, khalidwe loyamba, luso lamakono ndi kupindula limodzi, ndipo ili ndi chidaliro chopereka makasitomala moona mtima zinthu zamtengo wapatali.zopangidwa, mitengo yampikisano ndi ntchito zabwino kwambiri, komanso mu mzimu wapamwamba, wachangu, wamphamvu, pamodzi ndi anzathu, pitilizani kulanga kwathu tsogolo labwino.
