Zojambula: Mu gawo la madzi otayirata ndi zinyalala zotsalira, Pac ndi Pam zagwiritsidwa ntchito kwambiri monga zodziwika bwino monga zida zodziwika bwino komanso zothandizira kudzoza. Pepala ili limafotokoza za ntchito yofunsira ndi kafukufuku wa Pac -m m'malo osiyanasiyana, amafotokoza mwachidule kumvetsetsa ndi malingaliro a ofufuza osiyanasiyana pamwazi ndi mfundo zoyeserera. Malinga ndi zomwe zidachitika ndikuwunika zotsatirazi, pepalali likufotokoza mfundo yamkati ya Pac-Pakufunsiranso kuti kuphatikiza kwa Pac
Mawu osakira: polyulumumium chloride; Polyacrylamide; Chithandizo madzi; Gwedeza
-Ufaliri
Mu gawo la mafakitale, kugwiritsa ntchito kophatikizana kwa polyilumium chloride (Pac) ndi polyacryamide (Pam) kuti muchite unyolo wamagetsi, koma chibowo cholumikizira cha ntchito zosiyanasiyana chimakhala chosiyananso.
Pepalali limasanthula kwambiri mabuku ambiri opezeka kunyumba ndi kunja, akufotokozera mwachidule njira zophatikizira za Pac ndi Pac, zomwe zikutsogolera kufunikira kwa kafukufuku wofananira.
1. Apple Kafukufuku Wofufuza za Pac-Pam
Mphamvu ya Pac ndi Pam imagwiritsidwa ntchito m'magawo onse amoyo, koma mlingo ndi njira zothandizira mankhwalawa ndi osiyana ndi malo othandizira komanso malo othandizira.
1.1 Homettontal Beage ndi Maunicles Sludge
Zhao Yueyang (2013) ndipo ena adayesa ntchito yophatikiza Pam ngati thandizo la Pac ndi Pafc pogwiritsa ntchito njira yoyeserera m'nyumba. Kuyesawo kunapeza kuti zotsatira za pacy za pac pambuyo polumikizana zidawonjezeka kwambiri.
Wang Mutong (2010) ndipo ena adaphunzira mankhwala a pac + atakhala paubwana wa pac.
Lin Yingzi (2014) et al. Anaphunzira ntchito yowonjezera ya Pac ndi Pam pa algae mumadzi a mankhwala. Yang Hongmei (2017) et al. Anaphunzira mankhwala ogwiritsira ntchito mankhwala ophatikizidwa pa Kimki kutaya, ndipo anaganizira kuti mtengo wolimba wa pH unali 6.
Fu peiqian (2008) et al. Anaphunzira zotsatira za malo ophatikizika omwe amafunsira kugwiritsa ntchito madzi. Mwa kuyeza kuchotsa zotsatira za zosanja monga kuwonongedwa, TP, CP, CP ndi phosphate m'madzi, zimapezeka kuti malo ophatikizika amachotsa mitundu yonse.
Cao Touttian (2012) ndipo ena adatengera njira yofala kuti athetse mavuto a kuselitsira, kuwala komanso kovuta kumira pamadzi chithandizo chamadzi kumpoto chakum'mawa China.
Liu Hao (2015) et al. Anaphunzira mankhwala osokoneza bongo potengera kuyimitsidwa kovuta komanso kuyimitsidwa kotsitsimutsa kwa pakamwa, ndipo anapeza kuti kuwonjezera pamtunda womwe ukuwonjezera Pam ndi Pac kungalimbikitse zotsatira zomaliza.
1.2 kusindikiza ndi kupatsa madzi owononga ndi mapepala opanga zinyalala
Zhang Lanya (2015) et al. Anaphunzira mgwirizano wogwirizana wa Chitosan (CTS) ndi coagunt pochiza pepala lopanga mapepala, ndikuwona kuti zinali bwino kuwonjezera Chitosan
Kuchotsa mitengo kwa cod ndi kugwedezeka kunawonjezeredwa ndi 13.2% ndi 5.9%.
Xie Lin (2010) adaphunzira zotsatira za pac ndi Pam kuphatikiza mankhwala opanga mapepala.
Liu zijang (2013) ndi ena omwe amagwiritsa ntchito pac yodzipangira ndi Pac Corcolite yogwirizana ndi akupanga yolumikizidwa ndi akupanga ntchito yosindikiza ndi kupaka madzi owononga. Anazindikira kuti mtengo wamtengowo utakhala pakati pa 11 ndi 13, Pac adawonjezeredwa koyamba ndikulimbikitsidwa kwa mphindi 2, kenako pac adawonjezeredwa ndikusunthidwa kwa mphindi 3, zotsatirapo zake zinali zabwino kwambiri.
Zhoun Danni (2016) ndipo ena adaphunzira mankhwala a Pac + Pac + Pac unali wabwino kwambiri kuposa momwe amathandizira pakuwaza kwamadzi.
Wang zhizhi (2014) et al. Yophunziridwa njira yochizira mankhwala yopanga mapepala okhala ndi mapepala okhala ndi pac + Pac 'Pam ngati gawo la njira. Mlingo wa pac ndi 250 mg / l, mlingo wa Pam ndi 0,7 mg / l, ndipo mtengo wa pH suyenera kukhala wosalowererapo, zomwe zimachotsa ku COD.
Zuo Weiyuan (2018) ndipo ena adaphunzira ndikuyerekeza zomwe zidasakanikirana za Feya4 / Pac / Pac. Kuyesedwa kumawonetsa kuti kuchuluka kwa atatuwo ndi 1: 2: 1: 1, mankhwala osindikizira osindikiza ndi kupatsa madzi owononga ndikopambana.
Lv wochimwa (2010) et al. Anaphunzira chithandizo cha mankhwala a Pac + Pac pagawo lapakati la zinyalala. Kafukufukuyo akuwonetsa kuti polota colowin zotsatira zabwino kwambiri m'malo acidic (Ph 5). Mlingo wa pac ndi 1200 mg / l, Mlingo wa Pam ndi 120 mg / l, ndi chiwonetsero chochotsa ma cod ndi oposa 60%.
1.3 Mankhwala a Chee Palace Bowter ndi Kuyenga Madzi Oyera
Yang lei (2013) et al. Anaphunzira ntchito yophatikiza yokhudza Pac + Pac pa makampani ogulitsa madzi amoto, poyerekeza ndi zotsalazo pansi pa zigawo zingapo, ndikupereka Mlingo wosinthidwa wa Pam malinga ndi kusokonekera kosiyana kotsatira.
FAng XIOOLIng (2014) ndipo ena adafanizira ndi kuphatikiza kwa pac + chi ndi Pac + Pam pamoto woyeretsa zinyalala. Anamaliza kuti Pac + Chiti anali ndi zotsatira zabwino zanyumba ndi kukonza kwa code. Zotsatira zoyesera zomwe zikuwonetsa kuti nthawi yabwino yosangalatsa inali 10 min ndi okwera mtengo.
Deng lei (2017) et al. Anaphunzira za Polota za Pac + Pam pa Kubowola Madzimadzi amadzimadzi, ndipo kuchuluka kwa mankhwalawa kunafikira oposa 80%.
Wu Jinhua (2017) et al. Anaphunzira ku mankhwalawa a cal Cheal Chermater ndi coalation. Pac ndi 2 g / l ndi Pam ndi 1 mg / l. Kuyesera kumawonetsa kuti mtengo wabwino kwambiri ndi 8.
Guo Jinal (2009) et al. Anaphunzira mankhwala ochizira madzi a maluwa a comptoct ndipo amaganiza kuti kuchotsedwako kunali kwabwino kwambiri pomwe Mg ndi Pam ndi 0,3 mg / l.
Lin lu (2015) et al. Anaphunzira zotsatira za polota za pac -m kuphatikiza mafuta ophatikizika okhala ndi madzi onyansa pansi pamikhalidwe yosiyanasiyana, ndikuyerekeza zotsatira za nyumba yosakwatiwa. Mlingo womaliza ndi: Pac 30 mg / l, Pam6 mg / l, kutentha kozungulira 40 ℃ M'mikhalidwe yabwino kwambiri, kuwongolera kwa COD kumafika pafupifupi 85%.
Mapeto 2 ndi malingaliro
Kuphatikiza kwa polyulumium chloride (pac) ndi polyacryamide (Pam) kwagwiritsidwa ntchito kwambiri m'magawo onse amoyo. Ili ndi kuthekera kwakukulu mu gawo la madzi otayika ndi sludge chithandizo, ndipo mtengo wake umayenera kuti uwonjezere.
Njira Yophatikiza Pac ndi Pam makamaka zimatengera zabwino kwambiri za Pam macrorolecular unyolo, wophatikizidwa ndi Al3 + ku Pac ndi - ONE PERTINE PANGANI ZINSINSI ZAULERE. Kapangidwe ka netiweki kumatha kukweza zodetsa zina monga tinthu tokha ndi madontho amafuta, motero ili ndi mankhwala ambiri amankhwala osokoneza bongo okhala ndi mitundu yambiri, makamaka yolumikizira mafuta ndi madzi.
Nthawi yomweyo, kuphatikiza kwa Pac ndi Pam kumakhalanso ndi vuto. Madzi omwe amapangidwa ndi omwe amapangidwa ndewu ndi okwera, ndipo mawonekedwe ake amkati amabweretsa zofunika kwambiri kuti alandirenso sekondale. Chifukwa chake, chitukuko chowonjezereka cha pac ophatikizidwa ndi Pam amayang'anabe zovuta komanso zovuta.
