Decolorizing Flocculants: "Magic Cleaner" a Sewers za Urban

Mawu Ofunika Kwambiri:Decolorizing flocculants, decolorizing agents, decolorizing wothandizira opanga

Pamene kuwala kwa dzuŵa kumawomba mumzindawo, mapaipi osaŵerengeka osaoneka amatulutsa mwakachetechete zimbudzi zapakhomo. Zamadzimadzi zakuda zimenezi, zonyamula madontho amafuta, zotsalira za zakudya, ndi zotsalira za mankhwala, zimayendayenda m’mapaipi ocholoŵana kwambiri. Mu "nkhondo yoyeretsa" yachete iyi, mankhwala otchedwa decolorizing flocculant amagwira ntchito yofunika kwambiri.

Mtundu wa zimbudzi mu ngalande nthawi zambiri umasonyeza mwachindunji kuipitsidwa kwake. Madzi a bulauni akuda amachokera ku madzi otayira, mafuta ochulukirapo amawonetsa mafuta ochulukirapo, ndipo madzi abuluu achitsulo amatha kukhala ndi utoto waku mafakitale. Mitundu imeneyi simangokhudza maonekedwe komanso zizindikiro za zinthu zoipitsa. Njira zochiritsira zachikhalidwe, monga kusefera thupi ndi kuwonongeka kwachilengedwe, zimatha kuchotsa zonyansa zina koma zimavutikira kuthetsa vuto la mtundu. Pakadali pano, ma decolorizing flocculants amakhala ngati "ofufuza amitundu" odziwa bwino ntchito, kuzindikira ndikuwola zinthu zamitundu iyi.

Mfundo yogwirira ntchito yadecolorizing flocculantamafanana ndi "capture operation" ya microscopic. Pamene wothandizirawo akuwonjezeredwa kumadzi otayira, zosakaniza zake zogwira ntchito zimamanga mofulumira ku zowonongeka zowonongeka. Unyolo wa mamolekyuwa, monga ngati tinthu tambirimbiri totambasuka, timakutira tinthu ting'onoting'ono ta pigment, tinthu tating'onoting'ono tomwe timagwira ntchito. Pansi pa "kumanga" zotsatira za ma chemical bonds, zoipitsa zomwe zinali zolekanitsidwa pang'onopang'ono zimawunjikana m'magulu owoneka, pang'onopang'ono kukhazikika ngati ma snowflakes. Izi sizimangochotsa mtundu komanso zimachepetsa kwambiri COD (Chemical Oxygen Demand) ndi BOD (Biochemical Oxygen Demand) m'madzi.

M'malo oyeretsera madzi onyansa, kugwiritsa ntchito ma decolorizing flocculants kumapitilira kuchotsera mitundu. Kafukufuku wochitika m'malo ogulitsa mafakitale akuwonetsa kuti utoto ndi kusindikiza madzi otayira omwe amathiridwa ndi wothandizila uyu adakwanitsa kuchotsa utoto wopitilira 90%, pomwe akukumananso ndi kuchepa kwakukulu kwazitsulo zolemera. Chochititsa chidwi kwambiri, wothandizira uyu amasunga ntchito yake pa kutentha kochepa, kuthetsa vuto la kuchepa kwa madzi owonongeka m'nyengo yozizira. Pogwiritsa ntchito ukadaulo wa microencapsulation, ma decolorizing flocculants tsopano atha kumasulidwa bwino, kupewa zinyalala komanso kuchepetsa kuipitsidwa kwachiwiri kwa chilengedwe.

Pamene chitetezo cha chilengedwe chimakhala nkhani yaikulu, kafukufuku ndi chitukuko cha decolorizing flocculants akupita ku "green chemistry." Kutuluka kwa bio-based flocculants kwasintha zopangira kuchokera ku mafuta a petroleum kupita ku zokolola; kugwiritsa ntchito nanotechnology kwachepetsa mlingo ndi 30% pomwe kuwirikiza kawiri mphamvu yake. Zatsopanozi sikuti zimangochepetsa mtengo wamankhwala komanso zimapangitsa kuti madzi otayira azitsuka okhawo azikhala okonda zachilengedwe. Muntchito yokonzanso madambo m'malo osungira zachilengedwe, kuphatikiza kwa ma flocculants ochotsa mtundu komanso ukadaulo wopangidwa ndi madambo adapanga bwino "sefa yachilengedwe" yomwe imayeretsa madzi ndikukongoletsa chilengedwe.

Kukada, magetsi a mumzindawo amaunikira dera lonselo pang’onopang’ono. Madzi oyera omwe amapangidwa ndi decolorizing flocculants amayenda m'mipope yapansi panthaka kupita ku mitsinje, mpaka kukafika kunyanja. Pa “kusintha kwa zinthu zoyeretsa” kumeneku, mankhwala ooneka ngati wamba amenewa akuteteza moyo wa mzindawu pogwiritsa ntchito nzeru zongoyerekeza ndi mamolekyu. Ngakhale kuti timasangalala ndi madzi aukhondo, mwina tiyenera kukumbukira kuti mkati mwa mapaipi osaonekawo, gulu la “oteteza mankhwala” likugwira ntchito mwakachetechete.
