Ubwino wa polyaluminum chloride wothandiza kwambiri pochiza madzi otayira

Chifukwa cha kufulumira kwa mafakitale, kutayidwa kwa zinyalala kwakhala nkhani yaikulu pa kuteteza chilengedwe padziko lonse lapansi. Mfundo yaikulu pakukonza zinyalala ndi kusankha ndi kugwiritsa ntchitomankhwala osakanizaMu ndondomeko yoyeretsera. M'zaka zaposachedwapa, polyaluminum chloride (PAC) yogwira ntchito bwino kwambiri, monga flocculant yofunika kwambiri, pang'onopang'ono yakhala "chogulitsa chapamwamba" mumakampani oyeretsera zinyalala chifukwa cha magwiridwe ake abwino komanso kuthekera kwake kogwiritsa ntchito bwino zinthu zosiyanasiyana.

Polyaluminum chloride ndi polima yopanda organic yokhala ndi mphamvu yothamanga kwambiri. Imapezeka ndi polymerization reaction ya aluminiyamu chloride ndi aluminiyamu hydroxide pansi pa mikhalidwe inayake. Poyerekeza ndi ma flocculants achikhalidwe amchere a aluminiyamu (monga aluminium sulfate, aluminium salt coagulant, ndi zina zotero), polyaluminum chloride yogwira ntchito bwino kwambiri ili ndi mphamvu yochotsa zoipitsa, makamaka ikakumana ndi kuipitsidwa kwakukulu ndi kuipitsidwa kwakukulu kwa mafuta. Kagwiridwe kake kabwino kwambiri pankhani ya ubwino wa madzi. Yagwiritsidwa ntchito kwambiri m'magawo ambiri monga kukonza zimbudzi za m'matauni, kukonza zimbudzi zamafakitale, ndi kukonza zimbudzi zapakhomo.

Ubwino wa polyaluminum chloride wothandiza kwambiri

1. Zotsatira za flocculation ndi zodabwitsa

Polyaluminum chloride yogwira ntchito bwino kwambiri imatha kupanga ma floc ambiri abwino m'madzi mwachangu, motero imayamwa bwino zinthu zolimba zopachikidwa, zinthu za colloidal ndi tizilombo toyambitsa matenda m'madzi. Imatha kuyamwa ndikuchotsa tinthu tating'onoting'ono topachikidwa, mafuta, ma ayoni achitsulo cholemera ndi zinthu zina zoipitsa m'madzi mwachangu. Makamaka pochita ndi ubwino wa madzi ovuta, zotsatira zake zimakhala zabwino kwambiri kuposa ma flocculants amchere a aluminiyamu. Pochiza zimbudzi, polyaluminum chloride yogwira ntchito bwino imatha kuwonjezera liwiro lokhazikika la thanki yopachikidwa m'madzi mwachangu, motero imafupikitsa kwambiri nthawi yochizira zimbudzi.

2. Ntchito zosiyanasiyana

Polyaluminium chloride yogwira ntchito bwino kwambiriImatha kusintha malinga ndi mitundu yosiyanasiyana ya madzi abwino, kuphatikizapo madzi okhuthala kwambiri, zimbudzi zamafuta ambiri, madzi okhala ndi zitsulo zolemera, ndi madzi okhuthala otsika kutentha, zomwe zimasonyeza kusinthasintha kwamphamvu. Imatha kuchotsa bwino zinthu zambiri zolimba ndi zoipitsa m'madzi, ndipo ingagwiritsidwe ntchito kwambiri pokonza zimbudzi m'magawo osiyanasiyana monga kayendetsedwe ka boma, mafakitale, ndi migodi. Mwachitsanzo, pokonza zimbudzi zapakhomo, madzi otayirira a pulp mill, madzi otayirira a zitsulo, madzi otayirira amakampani azakudya ndi zina zotero, polyaluminum chloride yogwira ntchito bwino imatha kupeza zotsatira zabwino kwambiri pakukonza.

3. Mlingo wochepa, magwiridwe antchito apamwamba komanso kusunga mphamvu

Polyaluminium chloride yogwira ntchito bwino kwambiri yapangidwa kuti ipeze mlingo wochepa komanso zotsatira zabwino za flocculation. Mlingo wa turbidity yochepa ndi 25-40% ya aluminiyamu sulfate, ndipo mlingo wa turbidity yambiri ndi 10-25% ya aluminiyamu sulfate. Izi sizimangochepetsa mtengo wogwiritsa ntchito mankhwala, komanso zimachepetsa kugwiritsa ntchito mphamvu ndi matope pokonza zinyalala. Chifukwa cha zotsalira zake zochepa za aluminiyamu, zimachepetsa kuipitsa kwachiwiri kwa madzi ndikuchepetsa kwambiri mtengo wonse wokonza zinyalala. Chifukwa chake, chakhala chida chofunikira kwambiri chosungira ndalama ndikuwonjezera magwiridwe antchito.

4. Yoteteza chilengedwe

Kugwiritsa ntchito polyaluminium chloride yogwira ntchito bwino kwambiri sikukhudza chilengedwe komanso zotsalira zochepa za aluminiyamu. Poyerekeza ndi mankhwala ena osungunuka, polyaluminium chloride ndi yotetezeka ndipo sikukhudza kwambiri pH ndi TA ya zinyalala, kotero kufunikira kwa mankhwala osinthira pH ndi TA kumachepa. Makamaka m'mapulojekiti akuluakulu osamalira zinyalala ndi kuteteza chilengedwe, yakhala chisankho chobiriwira komanso chosamalira chilengedwe.

5. Yoyenera kutsukidwa ndi madzi otentha komanso otentha kwambiri

Kukonza madzi m'nyengo zotentha kwambiri ndi vuto lalikulu. Makamaka m'nyengo yozizira, mphamvu ya ma flocculant ambiri achikhalidwe idzachepa kwambiri. Komabe, polyaluminum chloride yogwira ntchito bwino imatha kupitirizabe kukhala ndi mphamvu yothamanga kwambiri pansi pa kutentha kochepa. Kuphatikiza apo, pamene madzi akutentha kwambiri, PAC imasonyezanso mphamvu zogwirira ntchito mwamphamvu ndipo imatha kuchotsa bwino tinthu tomwe timayimitsidwa ndi zinthu zina za colloidal m'madzi. Pamadzi omwe ali ndi mafuta ambiri oipitsa, polyaluminum chloride yogwira ntchito bwino kwambiri imakhalanso ndi mphamvu yabwino kwambiri yochotsera mafuta.

6. Sinthani kuti mugwirizane ndi mitundu yosiyanasiyana ya pH

Polyaluminium chloride yogwira ntchito bwino kwambiri imatha kusintha kwambiri kusintha kwa pH ya madzi ndipo imatha kugwira ntchito bwino pa pH yochuluka. Kawirikawiri, PAC imatha kusunga mphamvu yabwino yothira madzi m'madzi okhala ndi pH yotsika (yokhala ndi asidi) kapena yapamwamba (ya alkaline), zomwe zimapangitsa kuti igwiritsidwe ntchito bwino m'madzi osiyanasiyana. 5.0-9.0 vs 5.5-7.5

7. Kupititsa patsogolo ntchito yokonza matope ndikuchepetsa kuchuluka kwa matope

Polyaluminum chloride yogwira ntchito bwino kwambiri imathandiza kufulumizitsa kukhazikika kwa tinthu tolimba m'madzi otayira madzi ndikuwonjezera magwiridwe antchito a thanki yosungira madzi mwa kukonza kuchulukana ndi kukhazikika kwa ma flocs. Kuphatikiza apo, chifukwa cha kuchuluka kwa polymerization ya polyaluminum chloride yogwira ntchito bwino kwambiri, ma flocs omwe amapangidwa amakhala olimba komanso okhazikika mwachangu, motero amachepetsa kuchuluka kwa matope omwe amapangidwa. Izi ndizofunikira kwambiri pakukonza ndi kutaya matope pambuyo pake, ndipo zitha kuchepetsa mtengo ndi zovuta pakukonza matope.

Zitsanzo za kugwiritsa ntchito polyaluminum chloride yogwira ntchito bwino kwambiri pochiza madzi otayira

1. Kuyeretsa zinyalala za m'matauni

Pankhani yokonza zimbudzi za m'matauni, polyaluminum chloride yogwira ntchito bwino ingagwiritsidwe ntchito kwambiri pa nthawi yokonza zimbudzi za m'madzi isanayambe komanso yachiwiri. Imatha kuchotsa bwino zinthu zolimba zomwe zimapachikidwa, zinthu za colloidal, mabakiteriya ndi tizilombo tina m'madzi, kupititsa patsogolo ubwino wa madzi, komanso kupereka madzi abwino kwambiri kuti agwiritsidwe ntchito pokonza zimbudzi za m'madzi. PAC yakhala imodzi mwa zinthu zodziwika bwino zomwe zimadzaza madzi m'malo okonzera zimbudzi m'mizinda yambiri m'dziko muno komanso kunja.

2.Kuchiza madzi otayira m'mafakitale

Pankhani yokonza madzi otayidwa m'mafakitale, polyaluminum chloride yogwira ntchito bwino imagwiritsidwanso ntchito kwambiri. Imagwira ntchito bwino pokonza madzi otayidwa m'mafakitale ochokera ku kusindikiza ndi kupaka utoto, kupanga mapepala, zikopa, electroplating ndi mafakitale ena, ndipo imatha kuchotsa bwino zinthu zoipitsa monga utoto, COD ndi BOD. Mwachitsanzo, mu metallurgy, magetsi, makampani opanga mankhwala, kupanga mapepala, kukonza chakudya ndi mafakitale ena, PAC ingathandize kuchotsa zitsulo zolemera, madontho a mafuta, tinthu tomwe timapachikidwa ndi zinthu zina zoipitsa m'madzi. Makamaka pokonza madzi otayidwa amafuta, PAC yawonetsa luso lake labwino kwambiri lochotsa mafuta ndipo imatha kuchepetsa kwambiri kuchuluka kwa mafuta m'madzi.

3. Kukonza madzi otayira m'migodi

Pankhani yokonza madzi otayira m'migodi, polyaluminum chloride yogwira ntchito bwino imatha kuchotsa mchere, matope ndi zinthu zina zomwe zimapachikidwa m'madzi, zomwe zimathandiza kubwezeretsa madzi ndi kubwezeretsa zachilengedwe m'madera amigodi. Popeza ubwino wa madzi m'madera amigodi ndi wovuta ndipo nthawi zambiri umakhala ndi zinthu zambiri zolimba zomwe zimapachikidwa ndi zitsulo zolemera, mphamvu yapamwamba ya polyaluminum chloride yogwira ntchito bwino kwambiri ndi yabwino kwambiri pamtundu uwu wa njira yokonza madzi otayira.

Mwambiri,polyaluminum chloride yogwira ntchito bwino kwambiri, monga chotsukira madzi chabwino kwambiri chotsukira zinyalala, chili ndi ubwino waukulu paukadaulo komanso chilengedwe. Makamaka pankhani ya dothi lalikulu, ubwino wa madzi ovuta, komanso kuipitsidwa kwa mafuta ambiri, chingathandize kwambiri pakutsuka zinyalala.
