Kuchotsa Utoto wa Flocculants: "Chotsukira Chamatsenga" cha Ma Sewers a M'mizinda

Mawu Ofunika a Nkhani:Zochotsa utoto wa flocculants, zochotsera utoto, opanga zochotsera utoto

Pamene kuwala kwa dzuwa kukudutsa mu mzindawu, mapaipi osawerengeka osaoneka akukonza zinyalala za m'nyumba mwakachetechete. Madzi odetsedwa amenewa, omwe amanyamula madontho a mafuta, zinyalala za chakudya, ndi zotsalira za mankhwala, amayendayenda mu mapaipi ovuta kwambiri. Mu "nkhondo yoyeretsa" iyi yachete, mankhwala otchedwa flocculant ochotsa utoto amachita gawo lofunika kwambiri.

Mtundu wa zinyalala m'zimbudzi nthawi zambiri umasonyeza mwachindunji kuchuluka kwa kuipitsidwa kwake. Madzi akuda a bulauni angachokere ku madzi otayira, pamwamba pa mafuta pamasonyeza mafuta ambiri, ndipo madzi abuluu achitsulo angakhale ndi utoto wa mafakitale. Mitundu imeneyi sikuti imakhudza maonekedwe okha komanso ndi zizindikiro zowoneka za zinthu zoipitsa. Njira zachikhalidwe zochizira, monga kusefa thupi ndi kuwonongeka kwa zinthu, zimatha kuchotsa zinyalala zina koma zimavutika kuthetsa vuto la mtundu. Pakadali pano, zinthu zochotsa utoto zimagwira ntchito ngati "ofufuza mitundu," kuzindikira molondola ndikuwononga zinthu zoipitsa izi.

Mfundo yogwirira ntchito yaflocculant yochotsa utotoZimafanana ndi "ntchito yogwira" ya microscopic. Pamene chinthucho chiwonjezeredwa ku madzi otayira, zosakaniza zake zogwira ntchito zimalumikizana mwachangu ndi zinthu zoipitsa zomwe zili ndi mphamvu. Maunyolo a mamolekyu amenewa, monga ma tentacles osawerengeka otambasulidwa, amaphimba mwamphamvu tinthu ta pigment tofalikira, zinthu za colloidal, ndi zinthu zazing'ono zolimba zomwe zimayimitsidwa. Pansi pa "kumangirira" kwa zomangira za mankhwala, zinthu zoipitsa zomwe zinali zitapatulidwa kale zimasonkhana pang'onopang'ono kukhala ma flocs owoneka, pang'onopang'ono kukhazikika ngati chipale chofewa. Njirayi sikuti imangochotsa mtundu komanso imachepetsa kwambiri kuchuluka kwa COD (Chemical Oxygen Demand) ndi BOD (Biochemical Oxygen Demand) m'madzi.

Mu malo oyeretsera madzi akuda, kugwiritsa ntchito mankhwala ochotsera utoto kumapitirira kuchotsera utoto. Kafukufuku wochokera ku malo osungiramo zinthu akuwonetsa kuti kuyika utoto ndi kusindikiza madzi akuda oyeretsera ndi mankhwalawa kunapangitsa kuti pakhale kuchuluka kochotsa utoto kopitilira 90%, komanso kuchepa kwakukulu kwa zinthu zachitsulo cholemera. Chodabwitsa kwambiri n'chakuti, mankhwala awa amasunga ntchito yake kutentha kochepa, kuthetsa vuto la kuchepa kwa mphamvu yoyeretsera madzi akuda m'nyengo yozizira. Pogwiritsa ntchito ukadaulo wa microencapsulation, mankhwala atsopano ochotsera utoto tsopano amatha kutulutsa bwino, kupewa zinyalala ndikuchepetsa kuipitsa kwachilengedwe.

Pamene kuteteza chilengedwe kukukhala nkhani yofunika kwambiri, kafukufuku ndi chitukuko cha zinthu zochotsa utoto m'nthaka zikupita ku "mankhwala obiriwira." Kutuluka kwa zinthu zochotsera utoto m'nthaka kwasintha zinthu zopangira kuchokera ku zinthu zochokera ku mafuta kupita ku zinthu zochokera ku zomera; kugwiritsa ntchito nanotechnology kwachepetsa mlingo ndi 30% pomwe kwachulukitsa kawiri mphamvu. Zatsopanozi sizimangochepetsa ndalama zoyeretsera komanso zimapangitsa kuti njira yoyeretsera madzi otayira ikhale yotetezeka kwambiri ku chilengedwe. Mu polojekiti yokonzanso malo onyowa m'malo osungira zachilengedwe, kuphatikiza zinthu zochotsera utoto m'nthaka ndi ukadaulo womangidwa m'malo onyowa kunapanga bwino "fyuluta yachilengedwe" yomwe imayeretsa madzi ndikukongoletsa chilengedwe.

Pamene usiku ukugwa, magetsi a mumzinda amaunikira pang'onopang'ono malo. Madzi oyera okonzedwa ndi zinthu zochotsa utoto amayenda kudzera m'mapaipi apansi panthaka kupita ku mitsinje, pamapeto pake n'kufika kunyanja. Mu "kusinthaku koyeretsa," mankhwala opangidwa mwachibadwa awa akuteteza moyo wa mzindawu ndi nzeru za mamolekyu. Ngakhale tikusangalala ndi madzi oyera, mwina tiyenera kukumbukira kuti mkati mwa mapaipi osawonekawo, gulu la "oteteza mankhwala" likugwira ntchito mwakachetechete.
