Whakarāpopototanga: i roto i te mara o te maimoatanga wai para me ngā toenga para, kua whānuitia te whakamahinga o te PAC me te PAM hei mea whakapūpū me hei mea āwhina i te whakakōkī. E whakaatu ana tēnei pepa i te pānga o te whakamahinga me te tūnga rangahau o te pac-pam i ngā mara rerekē, e whakaahua poto ana i te māramatanga me ngā tirohanga a ngā kairangahau rerekē mō te whakakotahitanga o te pac-pam, ā, e tātari whānui ana i ngā whakaritenga me ngā mātāpono o te whakamahinga o te pac-pam i raro i ngā āhuatanga whakamātautau rerekē me ngā āhuatanga mara. E ai ki ngā ihirangi me ngā hua tātari o te arotake, e tohu ana tēnei pepa i te mātāpono o roto o te pac-pam e whakamahia ana ki ngā āhuatanga mahi rerekē, ā, e tohu ana hoki he hapa anō hoki te whakakotahitanga o te PAC me te PAM, ā, me whakatau tōna momo whakamahinga me te horopeta i runga i te āhuatanga motuhake.
Kupumatua: polyaluminium chloride; Polyacrylamide; Maimoatanga wai; Whakahekenga wai
0 Whakataki
I roto i te mara ahumahi, ko te whakamahinga ngātahi o te polyaluminium chloride (PAC) me te polyacrylamide (PAM) hei rongoā i ngā para wai me ngā para rite kua hanga he mekameka hangarau pakari, engari kāore i te mārama te tikanga mahi tahi, ā, he rerekē anō hoki te ōwehenga horopeta mō ngā āhuatanga mahi rerekē i roto i ngā mara rerekē.
Ka tātarihia whānuitia e tēnei pepa te tini o ngā tuhinga e pā ana ki te kāinga me tāwāhi, ka whakarāpopototia te tikanga whakakotahi o te PAC me te PAC, ā, ka hangaia he tatauranga whānui mō ngā whakatau wheako maha me te pānga tuturu o te PAC me te PAM i roto i ngā momo ahumahi, he mea nui tēnei mō ngā rangahau anō i roto i ngā mara e pā ana.
1. Tauira rangahau tono ā-whare mō te pac-pam
E whakamahia ana te pānga honohono o te PAC me te PAM i ngā āhuatanga katoa o te ao, engari he rerekē te horopeta me ngā tikanga maimoatanga tautoko mō ngā āhuatanga mahi me ngā taiao maimoatanga rerekē.
1.1 te paru o te whare me te paru o te tāone
I whakamātauhia e Zhao Yueyang (2013) me ētahi atu te pānga totoka o te PAM hei āwhina totoka ki te PAC me te PAFC mā te whakamahi i te tikanga whakamātautau ā-roto. I kitea i roto i te whakamātautau kua tino piki ake te pānga totoka o te PAC i muri i te totoka PAM.
I rangahau a Wang Mutong (2010) me ētahi atu i te pānga o te PAC + PA ki te para o ngā whare i roto i tētahi tāone, ā, i ako hoki i te whai huatanga o te tango COD me ētahi atu tohu mā roto i ngā whakamātautau orthogonal.
I rangahauhia e Lin yingzi (2014) me ētahi atu te pānga whakanui ake o te PAC me te PAM ki te rimurimu i roto i te whare maimoatanga wai. I rangahauhia e Yang Hongmei (2017) me ētahi atu te pānga maimoatanga o te whakamahinga ngātahi ki te wai para kimchi, ā, i whakaarohia ko te uara pH tino pai ko te 6.
I rangahauhia e Fu peiqian (2008) me ētahi atu te pānga o te wai whakapūkara i whakamahia hei whakamahi anō i te wai. Mā te ine i ngā pānga tango i ngā poke pēnei i te paru, te TP, te COD me te phosphate i roto i ngā tauira wai, i kitea he pai te pānga tango a te wai whakapūkara i ngā momo poke katoa.
I whakamahia e Cao Longtian (2012) me ētahi atu te tikanga o te whakapūpū wai hei whakaoti rapanga o te tere tauhohenga puhoi, ngā whakapūpū wai māmā, me te uaua ki te totohu i roto i te tukanga maimoatanga wai i te raki-mā-rāwhiti o Haina nā te iti o te pāmahana i te takurua.
I rangahauhia e Liu Hao (2015) me ētahi atu te pānga o te rongoā whakapūkara ki te whakatārewatanga uaua o te whakatō me te whakaiti i te paru i roto i te paru o te whare, ā, i kitea ko te tāpiri i tētahi nui o te PAM whakapūkara me te tāpiri i te PAM me te PAC ka taea te whakatairanga i te pānga rongoā whakamutunga.
1.2 te tā me te tae i ngā wai para me te hanga pepa i ngā wai para
I rangahauhia e Zhang Lanhe (2015) me ētahi atu te pānga taunga o te chitosan (CTS) me te matū whakakōkī i roto i te maimoatanga o te wai para hanga pepa, ā, i kitea he pai ake te tāpiri i te chitosan.
I piki ake ngā reiti tango i te COD me te paru mā te 13.2% me te 5.9%.
I rangahau a Xie Lin (2010) i te pānga o te maimoatanga whakakotahi o te PAC me te PAM i te wai para o te hanga pepa.
I whakamahia e Liu Zhiqiang (2013) me ētahi atu te PAC me te PAC composite flocculant i hangaia e rātou anō, i konatunatua ki te ultrasonic hei rongoā i te wai para tā me te tae. I whakatauhia i te wā i waenga i te 11 me te 13 te uara pH, ka tāpirihia tuatahitia te PAC ka whakaohokia mō te 2 meneti, kātahi ka tāpirihia te PAC ka whakaohokia mō te 3 meneti, ko te hua maimoatanga te mea pai rawa atu.
I rangahau a Zhou Danni (2016) me ētahi atu i te pānga maimoatanga o te PAC + PAM ki te paru o roto, i whakataurite i te pānga maimoatanga o te whakatere koiora me te rongoā koiora, ā, i kitea he pai ake te PAC + PAM i te tikanga maimoatanga koiora i roto i te pānga tango hinu, engari he pai ake te PAC + PAM i te tikanga maimoatanga koiora i roto i te paitini kounga wai.
I rangahauhia e Wang Zhizhi (2014) me ētahi atu te tikanga maimoatanga o te wai para o te wāhanga waenga o te hanga pepa mā te whakamahi i te PAC + PAM coagulation hei wāhanga o te tikanga. Ina 250 mg/L te horopeta o te PAC, ko te horopeta o te PAM he 0.7 mg/L, ā, tata koretake te uara pH, ka eke te tere tango COD ki te 68%.
I rangahauhia e Zuo Weiyuan (2018) me ētahi atu te pānga o te rere o te wai i roto i te ranunga o te Fe3O4 / PAC / PAM, ā, i whakaritea hoki. E whakaatu ana te whakamātautau ina 1:2:1 te ōwehenga o ngā mea e toru, ko te pānga maimoatanga o te tā me te tae i te wai para te mea pai rawa atu.
I rangahauhia e LV sining (2010) me ētahi atu te pānga maimoatanga o te huinga PAC + PAM ki te wai para waenga. E whakaatu ana te rangahau ko te pānga flocculation hiato te mea pai rawa atu i roto i te taiao waikawa (pH 5). Ko te horopeta o te PAC he 1200 mg / L, ko te horopeta o te PAM he 120 mg / L, ā, ko te tere tango i te ika koti neke atu i te 60%.
1.3 wai para matū waro me te wai para whakamahine
I rangahauhia e Yang Lei (2013) me ētahi atu te pānga whakapūmau o te PAC + PAM i roto i te maimoatanga waipara o te umanga waro, i whakaritea te paru toenga i raro i ngā ōwehenga rerekē, ā, i hoatu te horopeta whakarerekē o te PAM i runga i ngā paru tīmatanga rerekē.
I whakaritea e Fang Xiaoling (2014) me ētahi atu te pānga whakapūmau o te PAC + Chi me te PAC + PAM ki te wai para o te whare hanga hinu. I whakatau rātou he pai ake te pānga whakapūmau o te PAC + Chi, ā, he nui ake te pai o te tango COD. I whakaatuhia e ngā hua whakamātautau ko te wā whakaoho pai rawa atu he 10 meneti, ā, ko te uara pH pai rawa atu he 7.
I rangahauhia e Deng Lei (2017) me ētahi atu te pānga o te PAC + PAM ki te wai para o te wai keri, ā, neke atu i te 80% te tere tango COD.
I rangahau a Wu Jinhua (2017) me ētahi atu i te maimoatanga o te wai para matū waro mā te whakapūmau. Ko te PAC he 2 karamu/rita, ā, ko te PAM he 1 mg/rita. E whakaatu ana te whakamātautau ko te uara pH pai rawa atu ko te 8.
I rangahauhia e Guo Jinling (2009) me ētahi atu te pānga maimoatanga wai o te flocculation hiato, ā, i whakaarohia ko te pānga tango te mea pai rawa atu ina ko te horopeta o te PAC he 24 mg/L, ā, ko te horopeta o te PAM he 0.3 mg/L.
I rangahauhia e Lin Lu (2015) me ētahi atu te pānga o te whakakotahitanga o te pac-pam ki te wai para i roto i te hinu whakapūkara i raro i ngā āhuatanga rerekē, ā, i whakaritea te pānga o te whakapūkara kotahi. Ko te horopeta whakamutunga ko: PAC 30 mg / L, pam6 mg / L, pāmahana taiao 40 ℃, uara pH kūpapa me te wā whakatō mō te neke atu i te 30 meneti. I raro i ngā āhuatanga tino pai, ka eke te pai o te tango COD ki te 85%.
2 ngā whakatau me ngā whakaaro
Kua whānuitia te whakamahinga o te polyaluminium chloride (PAC) me te polyacrylamide (PAM) i ngā āhuatanga katoa o te ao. He nui tōna pūmanawa i roto i te mara o te maimoatanga wai para me te paru, ā, me tūhuratia anō tōna uara ahumahi.
Ko te tikanga whakakotahi o te PAC me te PAM e whakawhirinaki ana ki te ngāwari o te mekameka macromolecular PAM, me te whakakotahitanga o te Al3+ i roto i te PAC me te –O i roto i te PAM hei hanga i tētahi hanganga whatunga pumau ake. Ka taea e te hanganga whatunga te ārai pūmau i ētahi atu poke pēnei i ngā matūriki totoka me ngā pata hinu, nō reira he pai te pānga maimoatanga mō te wai para me ngā momo poke maha, inā koa mō te noho tahi o te hinu me te wai.
I taua wā anō, he hapa anō hoki kei te whakakotahitanga o te PAC me te PAM. He nui te wai o te wai kua hangaia, ā, ko tōna hanganga ā-roto pumau ka nui ake ngā whakaritenga mō te maimoatanga tuarua. Nō reira, kei te pā tonu ngā uauatanga me ngā wero ki te whanaketanga tonu o te PAC me te PAM.
