Zosintha: pamunda wamankhwala osokoneza bongo ndi zotsalira zazinyalala, PAC ndi PAM akhala akugwiritsidwa ntchito ngati zida wamba zophatikizira komanso zothandizira coagulant. Papepalali limafotokoza momwe ntchitoyo ikuyendera komanso kafukufuku wa pac-pam m'malo osiyanasiyana, amafotokozera mwachidule kumvetsetsa ndi malingaliro a ofufuza osiyanasiyana pakuphatikizika kwa pac-pam, ndikuwunikiranso bwino zofunikira ndi mfundo za pac-pam pansi pazoyeserera zosiyanasiyana ndi mikhalidwe yamunda. Malinga ndi zomwe zawunikiridwa ndikuwunikanso, pepalali likuwonetsa mfundo zamkati mwa pac-pam zogwiritsidwa ntchito m'malo osiyanasiyana ogwira ntchito, ndikuwonetsanso kuti kuphatikiza kwa PAC ndi PAM kulinso ndi zolakwika, ndipo momwe amagwiritsidwira ntchito ndi momwe akuyenera kuchitira khalani osankhidwa molingana ndi momwe zinthu zilili.

Review on research progress of pac-pam combination

Mawu osakira: polyaluminium mankhwala enaake; Polyacrylamide; Kuchiza madzi; Kuphulika

0 Chiyambi

M'munda mafakitale, ntchito kuphatikiza polyaluminium mankhwala enaake (PAC) ndi polyacrylamide (PAM) kuchitira madzi ogwiritsidwa ntchito ndi zinyalala ofanana wapanga unyolo okhwima luso, koma olowa kanthu limagwirira si bwino, ndi chiŵerengero mlingo wa zinthu zosiyanasiyana ntchito mu madera osiyanasiyana amakhalanso osiyana.

Papepalali likuwunika mozama mabuku ambiri kunyumba ndi kunja, ikufotokozera mwachidule njira zophatikizira za PAC ndi PAC, ndikupanga ziwerengero zokwanira pazomvetsetsa zosiyanasiyana kuphatikiza zotsatira za PAC ndi PAM m'mafakitale osiyanasiyana, zomwe zili ndi tanthauzo kuti mumve kafukufuku wambiri.

1. Chitsanzo chazofufuza zapakhomo za pac-pam

Mphamvu yolumikizana ya PAC ndi PAM imagwiritsidwa ntchito m'njira zosiyanasiyana, koma miyezo ndi njira zothandizirazo ndizosiyana pamikhalidwe ndi magwiridwe antchito.

1.1 Zimbudzi zanyumba ndi matope amatauni

Zhao Yueyang (2013) ndi ena adayesa mphamvu ya PAM ngati chothandizira ku PAC ndi PAFC pogwiritsa ntchito njira yoyesera m'nyumba. Kuyesaku kunapeza kuti mphamvu ya PAC itatha coagulation ya PAM idakulitsidwa kwambiri.

Wang Mutong (2010) ndi ena adaphunzira momwe PAC + PA imathandizira pa zimbudzi zapakhomo mtawuni, ndikuphunzira momwe kuchotsedwera kwa COD ndikuwonetsa zina mwazoyeserera za orthogonal.

Lin yingzi (2014) et al. Anaphunzira kuchuluka kwa mphamvu ya coagulation ya PAC ndi PAM pa algae mu chomera chomera madzi. Yang Hongmei (2017) et al. Anaphunzira momwe mankhwala amagwiritsidwira ntchito pamadzi amadzimadzi a kimchi, ndikuwona kuti phindu la pH labwino kwambiri linali 6.

Fu peiqian (2008) ndi al. Anaphunzira zotsatira za flocculant yogwiritsidwa ntchito kuti agwiritsenso ntchito madzi. Poyeza kuchotsedwa kwa zosafunikira monga kuzizira, TP, COD ndi phosphate m'madzi, zimapezeka kuti flocculant yothandizirayo imathandizira kuchotsa mitundu yonse yonyansa.

Cao Longtian (2012) ndi ena adagwiritsa ntchito njira yolumikizira kuti athane ndi zovuta zomwe zimachitika pang'onopang'ono, ma light flocs komanso ovuta kuzama munjira yochizira madzi kumpoto chakum'mawa kwa China chifukwa chakutentha kochepa m'nyengo yozizira.

Liu Hao (2015) et al. Ndidaphunzira zotsatira zamankhwala ophatikizika am'madzi pazovuta zovuta komanso kuchepetsa kuyimitsidwa kwa madzi amzimbudzi zapakhomo, ndipo adawona kuti kuwonjezera kuchuluka kwa PAM flocculate powonjezera PAM ndi PAC kumatha kulimbikitsa zotsatira zomaliza zamankhwala.

1.2 kusindikiza ndi kutaya madzi amadzi ogwiritsidwa ntchito komanso madzi owononga papermaking

Zhang Lanhe (2015) et al. Ndidawerenga momwe kugwirira ntchito kwa chitosan (CTS) ndikugwiritsidwira ntchito pochotsa madzi ogwiritsidwa ntchito popanga mapepala, ndikuwona kuti ndibwino kuwonjezera chitosan

Kuchuluka kwa kuchotsedwa kwa COD ndi kusokonekera kudakulitsidwa ndi 13.2% ndi 5.9%.

Xie Lin (2010) adaphunzira momwe PAC ndi PAM zimathandizira pochizira madzi ogwiritsidwa ntchito popanga mapepala.

Liu Zhiqiang (2013) ndi ena amagwiritsa ntchito zopangira PAC ndi PAC zophatikizira zophatikizika kuphatikiza akupanga kuti azisindikiza komanso kudaya madzi ogwiritsidwa ntchito. Zinatsimikiziridwa kuti pamene mtengo wa pH unali pakati pa 11 ndi 13, PAC idawonjezeredwa koyamba ndikulimbikitsidwa kwa 2 min, kenako PAC idawonjezeredwa ndikulimbikitsidwa kwa 3 min, chithandizo chake chinali chabwino kwambiri.

Zhou Danni (2016) ndi ena adaphunzira momwe mankhwala a PAC + PAM amathandizira pa zimbudzi zapakhomo, poyerekeza ndi momwe mankhwala amathandizira amathandizira pazachilengedwe ndi mankhwala, ndipo adapeza kuti PAC + PAM inali yabwinoko kuposa njira yothandizira pochotsa mafuta, koma PAC + PAM inali yabwinoko kuposa njira yothandizira pa zamoyo zamadzimadzi.

Wang Zhizhi (2014) et al. Anaphunzira njira yothandizira pochizira mapepala apakati apakati ndi PAC + PAM coagulation ngati njirayi. Mlingo wa PAC uli 250 mg / L, kuchuluka kwa PAM ndi 0.7 mg / L, ndipo pH mtengo wake sulowerera ndale, kuchuluka kwa kuchotsedwa kwa COD kumafika 68%.

Zuo Weiyuan (2018) ndi ena adaphunzira ndikuyerekeza kuyerekezera kosakanikirana kwa Fe3O4 / PAC / PAM. Kuyesaku kukuwonetsa kuti pamene kuchuluka kwa atatuwa ndi 1: 2: 1, zotsatira zakuthandizira pakusindikiza ndi kudaya madzi ogwiritsidwa ntchito ndi abwino kwambiri.

Kuchimwa kwa LV (2010) et al. Anawerenga momwe mankhwala amathandizira PAC + PAM kuphatikiza pamadzi am'madzi apakati. Kafukufukuyu akuwonetsa kuti kuphatikizika kwa magwiridwe antchito ndikwabwino kwambiri m'malo amchere (pH 5). Mlingo wa PAC ndi 1200 mg / L, kuchuluka kwa PAM ndi 120 mg / L, ndipo kuchuluka kwa kuchotsedwa kwa cod ndikoposa 60%.

1.3 Madzi amadzimadzi amafuta amakala ndi kuyeretsa madzi amdima

Yang Lei (2013) et al. Anawerenga momwe PAC + PAM imagwirira ntchito pochotsa madzi ogwiritsira ntchito malasha, poyerekeza ndi zotsalira zomwe zidatsalira, ndikupereka kusintha kwa PAM malinga ndi zovuta zina zoyambirira.

Fang Xiaoling (2014) ndi ena adafanizira kukokomeza kwa PAC + Chi ndi PAC + PAM pamadzi ochotsera madzi osamba. Adatsimikiza kuti PAC + Chi idachita bwino kugwirana ndi magwiridwe antchito ndikuchotsa bwino kwa COD. Zotsatira zoyeserera zidawonetsa kuti nthawi yoyeserera yoyenera inali 10 min ndipo mulingo woyenera wa pH udali 7.

Deng Lei (2017) ndi al. Anaphunzira kuchuluka kwa PAC + PAM pakuboola madzi amadzimadzi, ndipo kuchuluka kwa kuchotsedwa kwa COD kudafika pa 80%.

Wu Jinhua (2017) ndi al. Anaphunzira zamankhwala amadzimadzi amadzimadzi am'magazi ndi coagulation. PAC ndi 2 g / L ndipo PAM ndi 1 mg / L. kuyesaku kukuwonetsa kuti pH yabwino kwambiri ndi 8.

Guo Jinling (2009) ndi al. Anaphunzira momwe madzi amathandizira pakuthira madzi ndikuwona kuti kuchotsedwa kwake kunali koyenera kwambiri pomwe kuchuluka kwa PAC kunali 24 mg / L ndipo PAM inali 0.3 mg / L.

Lin Lu (2015) ndi al. Ndidawerenga momwe kukhathamira kwa pac-pam kumathandizira pamafuta osungunuka okhala ndi madzi amdima munthawi zosiyanasiyana, ndikuyerekeza kufananizidwa kwa flocculant kamodzi. Mlingo womaliza ndi: PAC 30 mg / L, pam6 mg / L, kutentha kozungulira 40 ℃, pH yopanda ndale komanso nthawi yopumira kuposa 30 min. Pazifukwa zabwino kwambiri, kuchotsedwa kwa COD kumafika pafupifupi 85%.

Review on research progress of pac-pam combination1

2 kumaliza ndi malingaliro

Kuphatikiza polyaluminium mankhwala enaake (PAC) ndi polyacrylamide (PAM) lakhala likugwiritsidwa ntchito m'magulu onse amoyo. Ili ndi kuthekera kwakukulu pamunda wamadzi ogwiritsira ntchito zonyansa ndi sludge, ndipo kufunikira kwake kwamakampani kuyenera kufufuzidwa.

Kuphatikiza kwa PAC ndi PAM makamaka kumadalira ductility yabwino ya PAM macromolecular chain, kuphatikiza ndi Al3 + mu PAC ndi - O mu PAM kuti apange makina okhazikika kwambiri. Kapangidwe kake kamatha kuvunditsa zonyansa zina monga tinthu tolimba ndi madontho amafuta, motero imakhala ndi chithandizo chabwino kwambiri pamadzi ogwiritsidwa ntchito ndi zodetsa zamitundu yambiri, makamaka pakakhala mafuta ndi madzi.

Nthawi yomweyo, kuphatikiza kwa PAC ndi PAM kumakhalanso ndi zopindika. Zomwe zili m'madzi a flocculate omwe amapangidwa ndi okwera, ndipo mawonekedwe ake okhazikika amatsogolera kuzithandizo zofunikira. Chifukwa chake, kupititsa patsogolo kwa PAC kuphatikiza PAM kukukumanabe ndi zovuta ndi zovuta.
