He pai te painga o te coagulant maimoatanga parakaingaki me te flocculant ina whakamahia tahi

In Whakahau (Polyalumine Chloride, e mohiotia ana ko te kaihoko horoi wai, e mohiotia ana ano he polyaluminum chloride, polyaluminum mo te poto,PAC) meKarekau (polyacrylamide, no te polymer ngota teitei,PAM) I raro i te mahi, ka uru te matū whakatarewa ki te kapoipoi tinana me te kapoi matū, na reira ka hanga he kahui matū whakatarewa nui.I raro i te kaha o te roopu mirumiru, ka rewa nga "floccules" ki te mata o te wai kia puta he paru, ka wehea mai i te wai ma te whakamahi i te parapara.Ko te horoi i te puha e kore e pakaru, ka whai hua te whakamahi i te coagulant me te flocculant i roto i te maimoatanga parakaingaki.

Ko te Coagulant (polyaluminum chloride, e mohiotia ana ko te purifier wai, e mohiotia ana ko te polyaluminum chloride, e kiia ana ko te polyaluminum, PAC) te nuinga o te whakamahi mo te horoi o te wai inu me te wai parakore ahumahi, me te maimoatanga o te kounga o te wai motuhake (penei i te parakaingi hinu, Te ta me te tae parakaingaki pepa, te whakarewa parapara, kei roto nga taonga iraruke, nga konganuku taumaha paitini penei i te Pb, Cr me te parakaingaki kei roto F, me etahi atu), hei taapiri, kei te whakamahia nuitia ki te maka tika, te keri hinu, te hiako, te hanga pepa whakarewa, me etahi atu, ka whakamahia te coagulant i roto i te wai I te wa o te maimoatanga, ko nga matūriki colloidal i roto i te wai ka taea te hono me te whakahiato tahi.I te nuinga o te waa, ko te mahi whakahiato ko te taapiri matū i te wa o te maimoatanga wai kia pai ai nga poke ki te whakakotahi, ki te whakaheke i te tae, ki te tango i nga totoka iri, ki te tango i te kohukohu me te huakita.

Ko te polyaluminum ferric chloride he pai te mahi coagulation.Ko te polyaluminum ferric chloride (PAFC) he momo hou o te tino pai o te cationic composite flocculant inorganic inorganic.Kei a ia nga painga o te mata whanui, te pai o te tango turbidity, me te iti o te waikura ki nga pipeline taputapu;kei a ia ano nga ahuatanga o te tere rino tote tote flocculant flocculation whakataunga, te wehenga ngawari, te mahi pai i roto i te maimoatanga wai iti, me te whānuitanga o te uara PH i roto i te maimoatanga wai.I tenei wa, kua whakamahia pai te polyaluminum ferric chloride i roto i te maimoatanga o te wai inu, te wai ahumahi me nga momo wai paru ahumahi.

Whakahau (ko te polyaluminum chloride, e mohiotia ana ko te kaihoko horoi wai, e mohiotia ana ko te polyaluminum chloride, e kiia ana ko te polyaluminum, PAC) he kaha te whakaheke me te whakakore i nga kaha, a ko te painga o te horoi wai ko te 4-6 nga wa o te AL2(SO4)3.3-5 wa te nui o te ALCL3, he iti te inenga, he nui te paanga, he iti te utu, he nui te painga, he pai te urutau ki te whānuitanga o te uara pH, he iti te whakahekenga o te uara pH o te wai mata. , no reira karekau he paheketanga ki runga i nga taputapu paipa, kaore he take ki te taapiri atu i etahi atu taapiri, a ka tere te hanga o nga flocs Heoi, he matotoru, he nui te mahi, he nui te totohu, me te tere o te rerenga, na reira ko te painga o te purenga ki runga i te wai turbidity teitei. kitea.
