一.Kuyambitsa mfundo yogwiritsira ntchito

Pakupenta, kuchuluka kwa utoto wa utoto kumangokhala 40 mpaka 60%, ndipo kupitilira theka la utotowo amawulukira mumlengalenga kuti apange chifunga chopopera, ndikuipitsa kwambiri mpweya ndi chilengedwe. Pofuna kuteteza bwino chilengedwe komanso kuyeretsa malo omangapo, njira yamadzi yozungulira yopopera yonyowa nthawi zambiri imagwiritsidwa ntchito m'makampani opaka utoto kuti agwire nkhungu yopaka utoto. Kuti mupitirize kugwira ntchito yopopera mankhwala, kukonza malo ogwirira ntchito, ndikupangitsa kuti makina oyeretsera azigwira ntchito bwino, tinthu tating'ono ta mankhwala tikuyenera kuwonjezeredwa ndikusungidwa m'madzi ozungulira, omwe amadziwika kuti paint mist coagulants. Ikhoza kukhudzana ndi tinthu tating'onoting'ono tomwe tagwidwa ndi madzi, kenako ndikuchitapo kanthu ndikupangitsa kuti chiwonongeke ndi kusokoneza, kusonkhanitsa mu flocculant ndi kukula kwa tinthu tating'ono, totchedwa paint slag, ndi kupatukana ndi madzi, kuti madzi azitha kugwiritsidwa ntchito. kwa nthawi yayitali. Ma coagulants a utoto amaphatikizanso mtundu wolimba wa alkali wobalalitsa, mtundu wa condensation adsorption, mtundu wa utoto wamtundu wamtundu wa condensation wamadzi, ndi zina zotere. Mitundu yomwe ili pamwambayi imatha kupangitsa utotowo kuti usasunthike ndi kuyandama motere: pangani utoto wa utoto saponification, kuthetsa kukhuthala kwake. , kupanga mankhwala a sopo a alkali osasungunuka m'madzi, omwazika m'madzi; Panthawi imodzimodziyo, nkhungu ya utoto imafupikitsidwa ndi kusokoneza chiwongoladzanja cha kunja kwa nkhungu ya utoto. The condensed particles amamangidwa mu flocculant ndi kugundana wina ndi mzake, ndiyeno polima flocculant ndi adsorbed ndi bridged kupanga lalikulu flocculant.

二.Momwe mungaweruze molondola zotsatira za utoto wa nkhungu flocculant

Zotsatira za coagulant ya utoto nthawi zambiri zimaweruzidwa kuchokera ku slag, madzi, thovu, fungo ndi zina zotero.
(1) Utoto wa slag: Kukhuthala kuyenera kukhala kochepa momwe kungathekere, ndipo mawonekedwe owoneka bwino ayenera kukhala osachepera 3 mpaka 4 (penti slag ndi granular kapena mchenga wabwino).
(2) Madzi: mu Eisenmann mbali otaya slagging chipangizo, pamaso slagging ndi pamaso kuwonjezera wothandizila B, utoto ayenera omwazika kwambiri turbidity madzi, ndipo madzi pambuyo kuwonjezera wothandizila B ayenera kukhala momveka bwino, ndipo mlingo madzi ayenera. kukhala osachepera giredi 3 (yopanda phokoso pang'ono).
(3) Foam: kutalika kwa chithovu mu dziwe kuyenera kukhala koyenera, ndipo sikuyenera kukhala kwakukulu kuposa kutalika kwa chithovu chopangidwa ndi madzi omwe ali ndi mankhwala okhawo omwe ali ofanana. Chithovucho ndi chokwera kwambiri, kusonyeza kuti kulekanitsa kwa utoto ndi madzi sikuli bwino.
(4) Kununkhira: Pa nthawi yogwiritsira ntchito, palibe fungo losasangalatsa lodziwika bwino lomwe liyenera kupangidwa, zomwe zimasonyeza kuti dongosolo la madzi lili ndi zoopsa za tizilombo toyambitsa matenda monga mildew ndi mabakiteriya, komanso zikhoza kuyambitsidwa ndi kulekanitsa kosauka kwa utoto ndi madzi, koma kugwiritsa ntchito. ma coagulants a utoto sangatulutse fungo loyipa, ndipo ma coagulant ambiri a utoto amawonjezedwa ku antibacterial agents.

三.Zinthu zomwe zimakhudza mphamvu ya flocculant ya utoto

(1) Mitundu ya utoto. Ngakhale palibe mgwirizano womwe wapezeka pakati pa mtundu wa utomoni ndi zotsatira za ntchito, zimadziwika kuti ma coagulants a utoto amakhudzidwa ndi polarity ya utomoni. Ma coagulants a utoto wamitundu yosiyanasiyana ndi hydrophilicity amayenera kugwiritsidwa ntchito motsatana popanga utoto wosiyanasiyana.

(2) PH mtengo kapena alkalinity. Zadziwika kuti alkalinity yoyenera kapena pH imathandizira kutulutsa utoto. Phindu la pH ndilokwera kwambiri, utoto umawonongeka chifukwa cha particles okhazikika omwazika m'madzi ovuta kusuntha, otsika kwambiri sangathe kuwonongedwa. Kuwongolera kwakukulu ndi 9.0, ndipo kuwongolera ndikofunikira kwambiri pakuyendetsa madzi ozungulira.

(3) Njira yopangira penti ndi penti ya slag pambuyo pa chithandizo. Njira yomwe imagwiritsidwa ntchito nthawi zambiri imaphatikizapo kuchapa, mtundu wa nsalu yotchinga madzi, nsalu yotchinga yamadzi - mtundu wotsuka, mtundu wa madzi ozungulira, mtundu wa Venturi ndi mitundu ina, ndipo njira zomwe zimagwiritsidwa ntchito pochotsa slag makamaka zimaphatikizapo mbale ya scraper, mtundu wa centrifugal, etc. Kupaka utoto kuchipinda chopopera, kuthamanga kwa madzi oyenda, kuthamanga, ndi njira yochotsera slag zidzakhudza momwe mungagwiritsire ntchito.

(4) zinthu za hydrochemical. Zonyansa m'madzi, monga kuuma, zidzakhudza kukula kwa tinthu tating'onoting'ono ta utoto, motero zimakhudza kutayika kwa mamasukidwe akayendedwe, kotero kuuma kuyenera kukhala kocheperako. Zonyansa zomwe zimayambitsidwa muzojambula zopopera, monga zosungunulira, makamaka zosungunulira zopanda polar, zimatha kuchepetsa kwambiri kuyamwa kwamadzi kuti kupaka chifunga.

(5) Mlingo ndi njira ya dosing ya penti mist coagulant. Ngati mlingowo ndi wochepa kwambiri, zotsatira za condensation si zabwino, ndipo ngati ndi zazikulu kwambiri, zimakhala ndi zotsatira zobalalika ndipo sizimapanga condensation. Njira zosiyanasiyana zoyamwitsa utoto wa utoto wopopera zimafunikira njira zosiyanasiyana zopangira madontho, zomwe ziyenera kufufuzidwa ndikutsimikizika pakugwiritsa ntchito kwenikweni.

(6) Tizilombo toyambitsa matenda. Kuchuluka kwa zinthu zamoyo m'madzi oyendayenda ndipamwamba kwambiri, ndipo machitidwe oyendetsa madzi ozungulira ndi oyenera kubereka ndi kukula kwa tizilombo toyambitsa matenda. Ngati sichikuyendetsedwa bwino, kuswana kwa tizilombo toyambitsa matenda kudzakhala ndi vuto logwiritsa ntchito ma coagulants a utoto. Mankhwala ophera tizilombo toyambitsa matenda kapena bacteriostatic ayenera kuwonjezeredwa nthawi zonse pamene kutentha kuli kwakukulu.
