Mawu Ofunika: Chotsukira utoto cha flocculant, chotsukira utoto, wopanga chotsukira utoto, Sinthani mtundu
Pakati pa mitsinje yoyera ndi nyanja zoyera, pali gulu la "zoteteza madzi abwino" zomwe sizikudziwika bwino - zomwe zimachotsa utoto wa flocculant. Monga wophika wodziwa bwino ntchito, amatha kusintha "msuzi" wakuda kukhala madzi oyera ngati galasi. Koma "wophika" uyu ali ndi mawonekedwe akeake; mlingo, kutentha, ndi njira yosakaniza zonse zimatsimikizira zotsatira za madzi abwino.
1. Mlingo: Wochuluka Kwambiri, Wochepa Kwambiri; Kusefukira kwa Madzi
Tangoganizani kuwonjezera madzi mukaphika phala: madzi ochepa kwambiri, ndipo phala lidzamamatira pansi; madzi ambiri, ndipo lidzakhala lochepa komanso lopanda kukoma. Mlingo wa flocculant yochotsa utoto umafunikanso kulamulidwa molondola. Fakitale ina yopangira nsalu, pofunitsitsa kupeza zotsatira mwachangu, inawonjezera mlingo woyenera ndi 30%, zomwe zinapangitsa kuti osati kulephera kukwaniritsa zotsatira zomwe mukufuna komanso ma floc okhuthala kwambiri omwe adakhazikika mwachangu kwambiri, zomwe zinalola mamolekyu otsala a utoto m'madzi kuti abwererenso ngati "nsomba zomwe zidalowa mu ukonde." Fakitale ina yopaka utoto, yomwe ikutsatira kwambiri chiŵerengero chovomerezeka cha 0.5‰, idapeza mlingo woyenera kudzera mu mayeso atatu ang'onoang'ono, pamapeto pake idakhazikitsa mtundu wa zinyalala pansi pa madigiri 10, kukwaniritsa muyezo wadziko lonse wa kutulutsa madzi a Gulu I.
2. Kutentha: Khodi Yothamanga ya Machitidwe a Zamankhwala
Zotsatira za kutentha pa zotsatira za flocculant zomwe zimapangitsa kuti utoto usinthe zimakhala ngati kuwiritsa dzira: madzi ozizira amafunika kuleza mtima, pomwe madzi otentha amachititsa kuti flocculant igwidwe mofulumira. Pa fakitale yopanga mapepala kumpoto kwa China, pamene kutentha kwa madzi kunatsika kufika pa 5°C m'nyengo yozizira, akatswiri anachepetsa nthawi ya flocculant kuchoka pa mphindi 30 mpaka mphindi 15 polamulira kutentha kwa flocculant pafupifupi 40°C, zomwe zinalola kuti unyolo wa mamolekyu ukule mokwanira. Pakadali pano, pa fakitale yopangira ma electroplating kum'mwera kwa China, panthawi ya kutentha kwambiri kwa chilimwe, anawonjezera retarder yomwe inasunga kutentha kwa reaction pansi pa 25°C, kuteteza floc kusweka.
3. pH Value: Luso la Acid-Alkalinity Balance
Kuchuluka kwa pH, monga acidity kapena alkalinity pa palette, kumakhudza mwachindunji "umunthu" wa flocculants. Fakitale yokonza chakudya, yosamalira madzi otayira mafuta, inapeza kuti pamene pH inali pakati pa 6 ndi 7, mamolekyu a flocculant amatha kukopa tinthu ta mafuta monga maginito. Komabe, pamene pH inapitirira 8, flocs inakhala yomasuka komanso yofooka, ndipo kuchuluka kwa COD kuchotsa kunachepa ndi 40%. Mwa kukhazikitsa chowunikira cha pH cha pa intaneti, akatswiri adapeza njira yowongolera nthawi yeniyeni, ndikukhazikitsa COD yotuluka pansi pa 50 mg/L.
4. Kusakaniza: Kulola Mamolekyulu Kuvina Waltz Yabwino Kwambiri
Liwiro ndi nthawi yosakaniza zili ngati kayimbidwe ka kuvina: mofulumira kwambiri zimaswa ma floc, pang'onopang'ono kwambiri sizingawasakanize bwino. Malo oyeretsera madzi otayira m'matauni adagwiritsa ntchito njira yosakaniza "mwachangu kenako pang'onopang'ono": mphindi ziwiri zoyambirira zidagwiritsidwa ntchito posakaniza mwachangu pa 150 rpm kuti zitsimikizire kuti flocculant yochotsa utoto ndi zoipitsa zikugwirizana mokwanira; mphindi zisanu zotsatira zidagwiritsidwa ntchito posakaniza pang'onopang'ono pa 30 rpm kuti ma floc akule pang'onopang'ono. Kuphatikizana kwa kusakaniza mwachangu ndi pang'onopang'ono kumeneku kunawonjezera kukula kwa tinthu ta floc kuchokera pa 50 μm kufika pa 200 μm, ndipo liwiro lokhazikika linawonjezeka ndi katatu.
5. Nthawi: Luso la Kutaya Madzi
Nthawi yokhazikika ili ngati njira yopangira vinyo: yochepa kwambiri ndipo vinyoyo ndi wofooka, wautali kwambiri ndipo umataya mphamvu zake zatsopano. Malo opangira mankhwala adapeza kudzera mu zoyeserera zoyerekeza kuti nthawi yokhazikika itakulitsidwa kuchokera pa mphindi 30 mpaka mphindi 45, kuchuluka kwa SS kuchotsa kunakwera kuchoka pa 85% mpaka 92%. Komabe, patatha mphindi 60, ma flocs okhazikika adabwezeretsedwanso chifukwa "chokhala nthawi yayitali," zomwe zidapangitsa kuti madzi otuluka abwererenso.
Kuyambira mlingo ndi kutentha mpaka pH ndi kusakaniza, tsatanetsatane uliwonse wa flocculant yochotsa utoto umatsimikiza mtundu wa madzi omaliza. Monga momwe mainjiniya wodziwa bwino ntchito yokonza madzi adanenera, "Sitikukonza madzi, koma tikulankhulana ndi mamolekyulu." Dontho lililonse la chinthucho likapeza malo ake oyenera, kutentha kulikonse kumakhala koyenera, ndipo mphindi iliyonse yothira madzi ikachitika moleza mtima, madzi oyera pamapeto pake adzachitira umboni kulemekeza chilengedwe.
