Mumunda weindasitiri, kushandiswa kwePolandaluminium chloride (pac) uye polyacrylwide
Iri pepa rinonzwisisika vanoongorora huwandu hwakakura hwemabhuku akakodzera kumba uye kune dzimwe nyika musanganiswa wePac uye Pam mune dzakasiyana maindasitiri, ayo ane kukosha kwekutungamira kuti awedzere kutsvagisa muminda ine hukama.
1. Domestic Express Rekusarudza Muenzaniso wePac-Pam
Iyo CrossLink Mhedzisiro yePAC uye PAM inoshandiswa mukufamba kwese kwehupenyu, asi iyo madhiri uye nzira dzekutsigira dzakasiyana dzakasiyana nemamiriro akasiyana ekushanda uye maratidziro ekurapa.
1.1 Domestic Sewage uye Incipal Sludge
Zhao Yueyang (2013) Uye vamwe vakaedza mari yemugodhi wePam seyakawisira rubatsiro kuPac uye pafc nekushandisa nzira yemukati bvunzo. Kuedza kwakawana kuti mari yekuzara yePAM mushure mekubatana kwePam.
Wang Mutong (2010) uye vamwe vakadzidza maitiro ekurapa wePac + PA pane imba yemimba mutaundi, uye akadzidza kuderedzwa kweCOD uye zvimwe zviratidzo kuburikidza neOrthogonal mayedzo.
Lin Yingozi (2014) et al. Akadzidza iyo yakawedzerwa coaglation mhedzisiro yePac uye PAM paAlgae mumvura kurapwa kwemvura. Yang Hongmei (2017) et al. Akadzidza maitiro ekurapa ekushandiswa kwekusanganiswa paKimchi akatsemuka, uye akafunga kuti ph kukosha kwakaringana pane 6.
Fu Peiqian (2008) et al. Akadzidza mhedzisiro yekuumbwa flocculant inoshandiswa kushandisa zvakare mvura. Nekuyera mhedzisiro yekubvisa yakadai seyakaoma, tp, cod uye phosphate mumasampula emvura, zvinowanikwa kuti flocetulant ine yakanaka yekubvisa pamarudzi ese okusvibiswa.
Cao LongTian (2012) Uye vamwe vakatanga nzira yekuumbwa kugadzirisa matambudziko ekugadzirisa matambudziko ekuita, akaoma kunyura muNortheast China nekuda kwekudziya kwakaderera munguva yechando.
Liu Hao (2015) et al. Akafunda kurapwa kwemanyorero emubatanidzwa pane zvakaoma pakumiswa uye kuderedzwa kwekudzora kwePam
1.2 Kudhinda uye Dyeing Wastwater uye Pepa remafuta
Zhang Lanhe (2015) et al. Akadzidza maitiro ekurambidza eChitosan (CTS) uye kabhuku kaCLE pakurapa kwemapepa emapepa asina mapepa, uye akawana kuti zvaive nani kuwedzera Chitosan
Mitero yekubvisa yeCOD uye turbidity yakawedzera ne13.2% uye 5.9%.
Xie Lin (2010) akadzidza mhedzisiro yePAC uye PAM yakasanganiswa kurapwa kwemapepa emapepa.
Liu Zhiqiang (2013) uye vamwe vakashandisa kuzvigadzira nec uye pac composite fleculant yakasanganiswa neUstrasonic nekurapa marara. Zvakagumiswa kuti kana iyo PH Kukosha kwaive pakati pegumi nemana uye 13, Pac yakatanga kuwedzerwa uye yakakurudzirwa kwemaminitsi maviri, uye ipapo pac yakawedzerwa uye yakakurudzirwa kwemaminitsi matatu, maitiro ekurapa aive akanakisa.
Zhou Danni (2016) uye vamwe vakadzidza maitiro ekurapa wePac + Pam On biological yechiitiko chekurapa, asi pac + pam yaive nani pane nzira yekubereka mumvura yemvura.
Wang Zhizhi (2014) et al. Akafunda nzira yekurapa yekurapa mapepa epakati yepakati Stackwater nePAC + Coglation sechikamu chenzira. Kana Dosage yePac is 250 mg / l, iyo dosage yePam ndeye 0.7 mg / l, uye iyo ph, uye iyo pro kukosha haina kurerekera, iyo cod yekubvisa kusvika 68%.
Zuo Weiyuan (2018) uye vamwe vakadzidza uye vachienzaniswa nemhedzisiro yekusanganisa mari yeFe3o4 / Pac / Pam. Muedzo unoratidza kuti kana iyo chiyero chevatatu chiri 1: 2: 1, maitiro ekurapa ekudhinda uye akasviba marara ndiye akanakisa.
LV SHURE (2010) et al. Akadzidza maitiro ekurapa ePac + PAM kusanganisa pane yepakati nhanho marara. Tsvagurudzo inoratidza kuti iyo inoumbwa floking mari ndiyo yakanyanya kunaka mumamiriro ekunze (PH 5). Iyo Dosage yePac ndeye 1200 mg / l, iyo dosage yePam ndeye 120 mg / l, uye iyo cod yekubvisa chiyero chinopfuura makumi matanhatu muzana.
1.3 marasha emakemikari marara uye anatsa tsvina
Yang lei (2013) et al. Akafunda mari yekolation yePac + PAM mune marasha emasango marara akareruka, uye akapa iyo yakagadziridzwa madhiri ePam zvinoenderana neyakajairika turbidity.
Fang Xiaoling (2014) uye vamwe vachienzanisa mari yemubatanidzwa wePac + Chi nePam + Pams paChinese Tsvina. Ivo vakagumisa kuti pac + chi kwaive nani flacculing mhedzisiro uye yepamusoro cod kubvisa zvakanaka. Mhedzisiro yekuedza yakaratidza kuti nguva yakachena inosimudzira yaive gumi nemaminitsi gumi uye ph kukosha pro yaive 7.
Deng Lei (2017) et al. Akafunda mugumo wePac + PAM paDutu remvura marara, uye iyo cod yekubvisa huwandu hwakasvika kupfuura 80%.
Wu Jinhua (2017) et al. Akadzidza kurapwa kwemarasha emamapu emazamu emazambiringa nekonzo. Pac is 2 G / L uye PAM ndeye 1 MG / L. Muedzo unoratidza kuti yakanakisa pH kukosha ndeye 8.
Guo jinling (2009) et al. Akadzidza iyo yemvura kurapwa kwemhedzisiro yemubatanidzwa uye akafunga kuti kubvisa kwayo yaive yakanyanya kunaka kana iyo Dosage yePac yaive makumi maviri nemana
Lin lu (2015) et al. Akafunda mari yekubhadhara yePac-Pam kusanganiswa nemafuta anoiswa pamvura ine marara pasi pemamiriro akasiyana, uye akafananidza mhedzisiro yeimwe floculant. Iyo yekupedzisira dosi ndeye: PAC 30 mg / l, Pam6 mg / l, ambient tempuricha 40 ℃, nekrate ph kukosha uye yakawedzera nguva yeanopfuura makumi matatu emaminitsi. Pasi pemamiriro ezvinhu akanaka kwazvo, iyo cod yekubvisa inoshanda inosvika 85%.
2 Mhedziso uye mazano
Iko kusanganiswa kwePolandaminium chloride (pac) uye polyacrrylambide (Pam) yakashandiswa zvakanyanya mumatanho ese ehupenyu. Iyo ine mukana mukuru mumunda wemarara uye svina kurapwa, uye kukosha kwayo kwemaindasitiri kunoda kuwedzeredzwa.
Iyo yekubatanidza michina yePAC uye PAM inonyanya kuenderana neiyo yakanakisa ductilCuility yePam macromolecular Carnec, yakasanganiswa neAl3 + muPAM uye (O MuPam yekuumba yakawedzera network network network. Iyo seti network inogona kutumira zvinosvibisa zvimwe zvinosvibiswa zvakadai seakasimba zvidimbu uye zvidhinha zvemafuta, saka zvine hunhu hwakanaka hwekurapa nemhando dzakawanda dzekusviba, kunyanya kune zvekushaiwa mafuta nemvura.
Panguva imwecheteyo, iyo musanganiswa wePac uye Pam zvakare ane urema. Mvura inoumbwa inoumbwa yakakwirira, uye chimiro charo chemukati chinotungamira kune zvinodikanwa zvepamusoro zvekutora kwechipiri kurapwa. Naizvozvo, kumwezve kukura kwePAC kwakabatanidzwa nePam kuchiri kutarisana nematambudziko nematambudziko.
