ʻŌlelo Pōkole: ma ke kahua o ka mālama ʻana i ka wai hoʻoneoneo a me nā koena ʻōpala, ua hoʻohana nui ʻia ʻo PAC a me PAM ma ke ʻano he mau flocculants maʻamau a me nā mea kōkua coagulant. Hoʻolauna kēia pepa i ka hopena noi a me ke kūlana noiʻi o pac-pam ma nā ʻano like ʻole, wehewehe pōkole i ka ʻike a me nā manaʻo o nā mea noiʻi like ʻole ma ka hui pū ʻana o pac-pam, a nānā pono i nā koi noi a me nā kumumanaʻo o pac-pam ma lalo o nā kūlana hoʻokolohua like ʻole a me nā kūlana kahua. Wahi a nā hopena o ka ʻike a me ka loiloi o ka loiloi, kuhikuhi kēia pepa i ke kumumanaʻo kūloko o pac-pam i hoʻopili ʻia i nā kūlana hana like ʻole, a kuhikuhi i ka hui pū ʻana o PAC a me PAM he mau hemahema nō hoʻi, a pono e hoʻoholo ʻia kāna ʻano noi a me ka nui e like me ke kūlana kikoʻī.

Ma ke kahua ʻoihana, ʻo ka hoʻohana pū ʻana o ka polyaluminium chloride (PAC) a me ka polyacrylamide (PAM) e mālama i ka wai hoʻoneoneo a me nā ʻōpala like ua hoʻokumu i kahi kaulahao ʻenehana makua, akā ʻaʻole maopopo kāna ʻano hana hui pū, a ʻokoʻa hoʻi ka lakio dosage no nā kūlana hana like ʻole ma nā ʻano like ʻole.
Hoʻopili piha kēia pepa i kahi nui o nā palapala pili i ka home a me waho, hōʻuluʻulu i ke ʻano hui pū ʻana o PAC a me PAC, a hana i nā helu helu piha ma nā hopena empirical like ʻole i hui pū ʻia me ka hopena maoli o PAC a me PAM ma nā ʻoihana like ʻole, nona ke alakaʻi koʻikoʻi no ka noiʻi hou aku i nā kahua pili.
1. Laʻana noiʻi noi kūloko o pac-pam
Hoʻohana ʻia ka hopena crosslinking o PAC a me PAM ma nā ʻano āpau o ke ola, akā ʻokoʻa ka nui o nā lāʻau a me nā ʻano lapaʻau kākoʻo no nā kūlana hana like ʻole a me nā wahi lapaʻau.
1.1 ka wai hoʻoheheʻe hale a me ka lepo o ke kūlanakauhale
Ua hoʻāʻo ʻo Zhao Yueyang (2013) a me nā poʻe ʻē aʻe i ka hopena coagulation o PAM ma ke ʻano he mea kōkua coagulant iā PAC a me PAFC ma ka hoʻohana ʻana i ke ʻano o ka hoʻāʻo ʻana 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 poʻe ʻē aʻe i ka hopena o ka mālama ʻana o PAC + PA ma ka wai ʻino home ma ke kūlanakauhale, a ua aʻo ʻo ia i ka pono o ka wehe ʻana o COD a me nā ʻōkuhi ʻē aʻe ma o nā hoʻokolohua orthogonal.
ʻO Lin yingzi (2014) et al. Ua aʻo i ka hopena coagulation i hoʻonui ʻia o PAC a me PAM ma luna o ka limu i loko o ka hale hana mālama wai. ʻO Yang Hongmei (2017) et al. Ua aʻo i ka hopena mālama o ka hoʻohana pū ʻana ma ka wai hoʻoneoneo kimchi, a ua manaʻo ʻia ʻo ka waiwai pH kūpono loa he 6.
Ua aʻo ʻo Fu peiqian (2008) et al. i ka hopena o ka flocculant composite i hoʻopili ʻia e hoʻohana hou i ka wai. Ma ke ana ʻana i nā hopena wehe o nā mea haumia e like me ka turbidity, TP, COD a me ka phosphate i loko o nā laʻana wai, ua ʻike ʻia he hopena wehe maikaʻi ka flocculant composite i nā ʻano mea haumia āpau.
Ua hoʻohana ʻo Cao Longtian (2012) a me nā poʻe ʻē aʻe i ke ʻano o ka flocculation composite e hoʻoponopono i nā pilikia o ka lohi o ka pane ʻana, nā flocs māmā a me ka paʻakikī ke piholo i ke kaʻina hana mālama wai ma ka Hikina ʻĀkau o Kina ma muli o ka mahana haʻahaʻa i ka hoʻoilo.
Ua aʻo ʻo Liu Hao (2015) et al. i ka hopena mālama ʻana o ka flocculant composite ma ka sedimentation paʻakikī a me ka hoʻemi ʻana o ka turbidity suspension i loko o ka wai ʻino home, a ua ʻike ʻo ka hoʻohui ʻana i kahi nui o ka PAM flocculate me ka hoʻohui ʻana i ka PAM a me PAC hiki ke hoʻolaha i ka hopena mālama hope loa.
1.2 ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai hoʻoneʻe a me ka hana pepa ʻana i ka wai hoʻoneʻe
Ua aʻo ʻo Zhang Lanhe (2015) et al. i ka hopena hoʻohui o ka chitosan (CTS) a me ka coagulant i ka mālama ʻana i ka wai hoʻoneoneo pepa, a ua ʻike ʻo ia he ʻoi aku ka maikaʻi o ka hoʻohui ʻana i ka chitosan.
Ua hoʻonui ʻia nā helu wehe o COD a me ka turbidity e 13.2% a me 5.9%.
Ua aʻo ʻo Xie Lin (2010) i ka hopena o ka hui pū ʻana o ka PAC a me PAM i ka wai hoʻoneoneo pepa.
Ua hoʻohana ʻo Liu Zhiqiang (2013) a me nā poʻe ʻē aʻe i ka PAC hana ponoʻī a me ka PAC composite flocculant i hui pū ʻia me ka ultrasonic e mālama i ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai hoʻoneoneo. Ua hoʻoholo ʻia i ka wā i waena o 11 a me 13 ka waiwai pH, ua hoʻohui mua ʻia ka PAC a hoʻoulu ʻia no 2 min, a laila ua hoʻohui ʻia ka PAC a hoʻoulu ʻia no 3 min, ʻo ka hopena lapaʻau ka mea maikaʻi loa.
Ua aʻo ʻo Zhou Danni (2016) a me nā poʻe ʻē aʻe i ka hopena mālama ʻana o PAC + PAM ma ka wai ʻino o ka home, ua hoʻohālikelike i ka hopena mālama ʻana o ka mea hoʻolalelale olaola a me ka lāʻau pale olaola, a ua ʻike ʻia he ʻoi aku ka maikaʻi o ka PAC + PAM ma mua o ke ʻano mālama olaola i ka hopena wehe ʻana o ka ʻaila, akā ʻoi aku ka maikaʻi o ka PAC + PAM ma mua o ke ʻano mālama olaola i ka ʻawahia o ka maikaʻi o ka wai.
Ua aʻo ʻo Wang Zhizhi (2014) et al. i ke ʻano hana o ka mālama ʻana i ka wai hoʻoneoneo waena o ka hana pepa ma o ka coagulation PAC + PAM ma ke ʻano he ʻāpana o ke ʻano hana. Ke 250 mg / L ka nui o ka PAC, ʻo 0.7 mg / L ka nui o ka PAM, a kokoke kūlike ka waiwai pH, hiki i ka helu wehe COD i 68%.
Ua aʻo ʻo Zuo Weiyuan (2018) a me nā poʻe ʻē aʻe a hoʻohālikelike i ka hopena flocculation hui ʻia o Fe3O4 / PAC / PAM. Hōʻike ka hoʻāʻo ʻana i ka wā he 1:2:1 ka lakio o nā ʻekolu, ʻo ka hopena mālama o ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai hoʻoneoneo ka mea maikaʻi loa.
LV sining (2010) et al. Ua aʻo ʻia ka hopena mālama ʻana o ka hui pū ʻana o PAC + PAM ma ka wai hoʻoneʻe waena. Hōʻike ka noiʻi ʻo ka hopena flocculation composite ka mea maikaʻi loa i kahi ʻano waikawa (pH 5). ʻO ka nui o ka PAC he 1200 mg / L, ʻo ka nui o ka PAM he 120 mg / L, a ʻoi aku ka nui o ka wehe ʻana o ke cod ma mua o 60%.
1.3 ka wai hoʻoheheʻe kemika lanahu a me ka wai hoʻoheheʻe hoʻomaʻemaʻe
Ua aʻo ʻo Yang Lei (2013) et al. i ka hopena coagulation o PAC + PAM i ka mālama ʻana i ka wai ʻino o ka ʻoihana lanahu, hoʻohālikelike i ke koena turbidity ma lalo o nā lakio like ʻole, a hāʻawi i ka dosage i hoʻoponopono ʻia o PAM e like me ka turbidity mua like ʻole.
Ua hoʻohālikelike ʻo Fang Xiaoling (2014) a me nā poʻe 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 hopena flocculation o PAC + Chi a ʻoi aku ka kiʻekiʻe o ka pono o ka wehe ʻana i ke COD. Ua hōʻike nā hopena hoʻokolohua ʻo ka manawa hoʻoulu kūpono he 10 min a ʻo ka waiwai pH kūpono he 7.
Ua aʻo ʻo Deng Lei (2017) et al. i ka hopena flocculation o PAC + PAM ma ka wai hoʻoheheʻe wai, a ua hōʻea ka helu wehe COD ma mua o 80%.
Ua aʻo ʻo Wu Jinhua (2017) et al. i ka mālama ʻana i ka wai hoʻoneoneo kemika lanahu ma o ka coagulation. ʻO 2 g / L ka PAC a ʻo 1 mg / L ka PAM. Hōʻike ka hoʻokolohua ʻo 8 ka waiwai pH maikaʻi loa.
Ua aʻo ʻo Guo Jinling (2009) et al. i ka hopena mālama wai o ka flocculation composite a ua manaʻo ʻo ia ka hopena wehe ʻana ʻo ia ka mea maikaʻi loa i ka wā he 24 mg / L ka nui o ka PAC a ʻo 0.3 mg / L ka PAM.
Ua aʻo ʻo Lin Lu (2015) et al. i ka hopena flocculation o ka hui pū ʻana o pac-pam ma ka ʻaila emulsified i loaʻa ka wai hoʻoneoneo ma lalo o nā kūlana like ʻole, a ua hoʻohālikelike i ka hopena o ka flocculant hoʻokahi. ʻO ka dosage hope loa: PAC 30 mg / L, pam6 mg / L, mahana ambient 40 ℃, waiwai pH kūlike a me ka manawa sedimentation no ka ʻoi aku ma mua o 30 min. Ma lalo o nā kūlana maikaʻi loa, hiki i ka pono o ka wehe ʻana o COD ma kahi o 85%.
2 hopena a me nā manaʻo kōkua
Ua hoʻohana nui ʻia ka hui pū ʻana o ka polyaluminium chloride (PAC) a me ka polyacrylamide (PAM) ma nā ʻano āpau o ke ola. Loaʻa iā ia ka hiki ke hana ma ke kahua o ka mālama ʻana i ka wai ʻino a me ka sludge, a pono e ʻimi hou ʻia kona waiwai ʻoihana.
ʻO ke ʻano hui pū ʻana o PAC a me PAM e hilinaʻi nui ʻia ana ma ka ductility maikaʻi loa o ke kaulahao macromolecular PAM, i hui pū ʻia me Al3 + ma PAC a me -O ma PAM e hana i kahi ʻano pūnaewele paʻa. Hiki i ke ʻano pūnaewele ke hoʻopuni paʻa i nā haumia ʻē aʻe e like me nā ʻāpana paʻa a me nā kulu aila, no laila he hopena mālama maikaʻi loa ia no ka wai hoʻoneoneo me nā ʻano haumia he nui, ʻoi aku hoʻi no ka noho pū ʻana o ka aila a me ka wai.
I ka manawa like, he mau hemahema nō hoʻi ka hui pū ʻana o PAC a me PAM. Kiʻekiʻe ka nui o ka wai o ka flocculate i hoʻokumu ʻia, a ʻo kona ʻano paʻa i loko e alakaʻi ai i nā koi kiʻekiʻe no ka mālama lua. No laila, ʻo ka hoʻomohala hou ʻana o PAC i hui pū ʻia me PAM e kū nei i nā pilikia a me nā pilikia.
