I ka ʻoihana ʻoihana, ʻo ka hoʻohana pū ʻana o ka polyaluminium chloride (PAC) a me ka polyacrylamide (PAM) e mālama i ka wai ʻino a me nā ʻōpala like i hoʻokumu i kahi kaulahao ʻenehana makua, akā ʻaʻole maopopo kona ʻano hana hui, a ʻo ka ratio dosage no nā kūlana hana like ʻole. ʻokoʻa hoʻi nā māla like ʻole.
Hoʻopili piha kēia pepa i ka helu nui o nā palapala kūpono ma ka home a ma waho, e hōʻuluʻulu i ka hui pū ʻana o PAC a me PAC, a hana i nā ʻikepili piha i nā hopena empirical like ʻole me ka hopena maoli o PAC a me PAM ma nā ʻoihana like ʻole, he alakaʻi koʻikoʻi. no ka noiʻi hou ʻana ma nā kahua pili.
1. Ka laʻana noiʻi noiʻi kūloko o ka pac-pam
Hoʻohana ʻia ka hopena crosslinking o PAC a me PAM ma nā ʻano like ʻole o ke ola, akā ʻokoʻa ke ʻano a me ke kākoʻo ʻana i nā ʻano lapaʻau no nā ʻano hana like ʻole a me nā wahi lapaʻau.
1.1 ka hoʻoheheʻe hale a me ka lepo o ke kūlanakauhale
Ua ho'āʻoʻo Zhao Yueyang (2013) a me nā mea'ē aʻe i ka hopena coagulation o PAM ma keʻano he kōkua coagulant i PAC a me PAFC ma o ka hoʻohanaʻana i keʻano o ka ho'āʻo i loko.Ua ʻike ka hoʻokolohua ua hoʻonui nui ʻia ka hopena coagulation o PAC ma hope o ka coagulation PAM.
Ua aʻo ʻo Wang Mutong (2010) a me nā mea ʻē aʻe i ka hopena o ka mālama ʻana o PAC + PA i ka wai hoʻoheheʻe hale ma ke kaona, a ua aʻo i ka maikaʻi o ka wehe ʻana o COD a me nā hōʻailona ʻē aʻe ma o nā hoʻokolohua orthogonal.
Lin yingzi (2014) et al.Ua aʻo ʻia i ka hopena coagulation i hoʻonui ʻia o PAC a me PAM ma luna o nā algae i loko o ka hale mālama wai.Yang Hongmei (2017) et al.Ua aʻo i ka hopena lapaʻau o ka hoʻohana ʻana i ka wai ʻōpala kimchi, a noʻonoʻo ʻia ʻo 6 ka waiwai pH maikaʻi loa.
Fu peiqian (2008) et al.Ua aʻo ʻia ka hopena o ka flocculant composite i hoʻohana hou ʻia i ka wai.Ma ke ana ʻana i nā hopena hoʻoneʻe o nā haumia e like me ka turbidity, TP, COD a me ka phosphate i loko o nā ʻano wai, ʻike ʻia he hopena maikaʻi loa ka flocculant composite ma nā ʻano haumia āpau.
Ua hoʻohana ʻo Cao Longtian (2012) a me nā mea ʻē aʻe i ke ʻano o ka flocculation composite e hoʻoponopono i nā pilikia o ka wikiwiki o ka pane ʻana, nā flocs māmā a paʻakikī hoʻi i ke kaʻina hana mālama wai ma Northeast Kina ma muli o ka haʻahaʻa haʻahaʻa i ka hoʻoilo.
Liu Hao (2015) et al.Ua aʻo i ka hopena lapaʻau o ka flocculant composite ma ka hoʻopaneʻe paʻakikī a me ka hoʻohaʻahaʻa ʻana i ka turbidity i ka hoʻokuʻu ʻia ʻana i loko o ka ʻōpala home, a ʻike ʻia ʻo ka hoʻohui ʻana i kekahi nui o ka PAM flocculate me ka hoʻohui ʻana i ka PAM a me ka PAC hiki ke hāpai i ka hopena lapaʻau hope loa.
1.2 ka paʻi ʻana a me ka waihoʻoluʻu ʻana i ka wai ʻino a me ka wai ʻōpala hana pepa
Zhang Lanhe (2015) et al.Ua aʻo i ka hopena hoʻohui o ka chitosan (CTS) a me ka coagulant i ka mālama ʻana i ka wai ʻino pepa, a ʻike ʻia ʻoi aku ka maikaʻi o ka hoʻohui ʻana i ka chitosan.
Ua hoʻonui ʻia ka nui o ka wehe ʻana o COD a me ka turbidity e 13.2% a me 5.9%.
Ua aʻo ʻo Xie Lin (2010) i ka hopena o ka PAC a me ka PAM i hui pū ʻia me ka mālama ʻana i ka wai ʻino pepa.
Ua hoʻohana ʻo Liu Zhiqiang (2013) a me nā mea ʻē aʻe i hana ponoʻī iā PAC a me PAC composite flocculant i hui pū ʻia me ke kani ultrasonic e mālama i ka paʻi ʻana a me ka wai kala ʻia.Ua hoʻoholo ʻia i ka wā i loaʻa ai ka pH ma waena o 11 a me 13, ua hoʻohui mua ʻia ka PAC a hoʻoulu ʻia no 2 min, a laila hoʻohui ʻia ka PAC a hoʻoulu ʻia no 3 min, ʻoi aku ka maikaʻi o ka hopena lapaʻau.
Ua aʻo ʻo Zhou Danni (2016) a me nā mea ʻē aʻe i ka hopena o ka mālama ʻana o PAC + PAM ma ka wai hoʻoheheʻe hale, hoʻohālikelike i ka hopena lapaʻau o ka biological accelerator a me ka biological antidote, a ʻike ʻia ʻoi aku ka maikaʻi o ka PAC + PAM ma mua o ke ʻano o ka lāʻau lapaʻau i ka hopena o ka ʻaila, akā. ʻOi aku ka maikaʻi o ka PAC + PAM ma mua o ke ʻano lapaʻau olaola i ka wai ʻona.
Wang Zhizhi (2014) et al.Ua aʻo ʻia i ke ʻano o ka mālama ʻana i ka wai ʻōpala i waena o ka papa waena e ka PAC + PAM coagulation ma ke ʻano o ke ʻano.Inā he 250 mg / L ka nui o ka PAC, ʻo ka nui o ka PAM he 0.7 mg / L, a ʻo ka helu pH ʻaneʻane kūʻokoʻa, hiki i ka helu hoʻohemo COD i 68%.
Ua aʻo ʻo Zuo Weiyuan (2018) a me nā mea ʻē aʻe i ka hopena flocculation hui ʻia o Fe3O4 / PAC / PAM.Hōʻike ka hoʻāʻo ʻana inā ʻo ka ratio o nā mea ʻekolu he 1:2:1, ʻoi aku ka maikaʻi o ka hopena lapaʻau o ka paʻi ʻana a me ke kala ʻana i ka wai ʻino.
LV sining (2010) et al.Ua aʻo ʻia ka hopena lapaʻau o ka hui ʻana o PAC + PAM ma ka wai ʻōpala waena.Hōʻike ka noiʻi ʻana ʻo ka hopena flocculation composite ʻoi aku ka maikaʻi ma ka ʻawaʻawa (pH 5).ʻO ka nui o ka PAC he 1200 mg / L, ʻo ka dosage o PAM he 120 mg / L, a ʻoi aku ka nui o ka wehe ʻana o ka cod ma mua o 60%.
1.3 ka wai ʻōpala kemika a me ka wai hoʻomaʻemaʻe
Yang Lei (2013) et al.Ua aʻo ʻia ka hopena coagulation o PAC + PAM ma ka ʻoihana lanahu hoʻomaʻemaʻe wai, hoʻohālikelike i ke koena turbidity ma lalo o nā ratio like ʻole, a hāʻawi i ke ʻano hoʻololi o PAM e like me ka turbidity mua.
Ua hoʻohālikelike ʻo Fang Xiaoling (2014) a me nā mea ʻē aʻe i ka hopena coagulation o PAC + Chi a me PAC + PAM ma ka wai hoʻomaʻemaʻe.Ua hoʻoholo lākou he ʻoi aku ka maikaʻi o ka flocculation a me ka maikaʻi o ka wehe ʻana o COD.Ua hōʻike ʻia nā hopena hoʻokolohua ʻo ka manawa hoʻouluulu maikaʻi loa he 10 min a ʻo ka waiwai pH maikaʻi loa he 7.
Deng Lei (2017) et al.Ua aʻo ʻia i ka hopena flocculation o PAC + PAM ma ka hoʻoheheʻe ʻana i ka wai ʻōpala, a ʻoi aku ka nui o ka wehe ʻana o COD ma mua o 80%.
Wu Jinhua (2017) et al.Ua aʻo ʻia i ka mālama ʻana i ka wai ʻino kemika ma ka coagulation.ʻO PAC ka 2 g / L a ʻo PAM ka 1 mg / L. hōʻike ka hoʻokolohua ʻo 8 ka waiwai pH maikaʻi loa.
ʻO Guo Jinling (2009) et al.Ua aʻo ʻia ka hopena mālama wai o ka flocculation composite a manaʻo ʻia ʻo ka hopena o ka wehe ʻana ʻoi aku ka maikaʻi inā ʻo PAC ka 24 mg / L a ʻo PAM ʻo 0.3 mg / L.
Lin Lu (2015) et al.Ua aʻo i ka hopena flocculation o ka hui ʻana o ka pac-pam ma ka ʻaila emulsified i loko o ka wai ʻino ma lalo o nā kūlana like ʻole, a hoʻohālikelike i ka hopena o ka flocculant hoʻokahi.ʻO ka hopena hope loa: PAC 30 mg / L, pam6 mg / L, ka mahana ambient 40 ℃, ka waiwai pH kūʻokoʻa a me ka manawa sedimentation no ka ʻoi aku o 30 min.Ma lalo o nā kūlana maikaʻi loa, hiki i ka hana hoʻoneʻe COD ma kahi o 85%.
2 hopena a me nā manaʻo
ʻO ka hui pū ʻana o ka polyaluminium chloride (PAC) a me ka polyacrylamide (PAM) ua hoʻohana nui ʻia i nā ʻano āpau o ke ola.Loaʻa iā ia ka mana nui ma ke kahua o ka wai ʻino a me ka mālama ʻana i ka lepo, a pono e ʻimi hou ʻia kona waiwai ʻoihana.
ʻO ka hui pū ʻana o PAC a me PAM e hilinaʻi nui ʻia i ka ductility maikaʻi loa o ke kaulahao macromolecular PAM, i hui pū ʻia me Al3 + i PAC a me - O i PAM e hana i kahi hoʻolālā pūnaewele paʻa.Hiki i ka ʻōnaehana pūnaewele ke hoʻopaʻa paʻa i nā mea haumia ʻē aʻe e like me nā ʻāpana paʻa a me nā kulu ʻaila, no laila he hopena maikaʻi loa ia no ka wai ʻino me nā ʻano haumia he nui, ʻoi aku ka nui o ka noho pū ʻana o ka aila a me ka wai.
I ka manawa like, he mau hemahema ka hui pū ʻana o PAC a me PAM.He kiʻekiʻe ka ʻike wai o ka floccule i hoʻokumu ʻia, a ʻo kona ʻano paʻa i loko e alakaʻi i nā koi kiʻekiʻe no ka mālama lua.No laila, ke kū nei ka hoʻomohala hou ʻana o PAC i hui pū ʻia me PAM i nā pilikia a me nā pilikia.
