PAC/PAM tikanga tono

Polyalumine pūhaumāota:Ko te PAC mo te poto, e mohiotia ana ko te konumohe chloride taketake, ko te hydroxyl aluminum chloride ranei.

Kaupapa:na roto i te hua hydrolysis o te polyaluminum chloride, te polyaluminum chloride ranei, ka tere te hanga o te rerenga colloidal i roto i te parakaingaki, i te paru ranei, he ngawari ki te wehe i nga matūriki nui o te rerenga.Mahinga:Ko te ahua me te mahi o te PAC e pa ana ki te alkalinity, te tikanga whakarite, te hanganga poke me te ihirangi alumina.

1, ka te alkalinity o parakore wai polyaluminum pūhaumāota ko i roto i te whānuitanga o 40% ~ 60%, ko reira he marama kowhai wai marama.Ina neke ake i te 60% te kawakore, ka huri haere hei wai marama kore tae.

2, ka he iti iho i te 30% te alkalinity, polyaluminum pūhaumāota mārō ko te arotahi.

3, ka ko te alkalinity i roto i te whānuitanga o 30% ~ 60%, he rauemi colloidal.

4, ka nui ake te alkalinity i te 60%, ka huri haere hei karaihe, he resin.Solid polyaluminum pūhaumāota i hanga o te kohuke kohuke uku he kowhai parauri ranei.

22-24% ihirangi:pahū whakamaroke tukanga production, kahore he pereti me te anga tātari, he teitei rauemi wairewa, ko te utu mākete o nāianei hua ahumahi, te nuinga whakamahia mō te maimoatanga wai para ahumahi.

26% ihirangi:hanga tukanga whakamaroke pahū, kahore he pereti me te anga tātari, he iti iho i te 22-24% te rauemi wairewa wai, ko tenei hua te paerewa o te motu o te karaehe ahumahi, he paku teitei ake te utu, ko te nuinga o te waa e whakamahia ana i roto i te maimoatanga wai para ahumahi.

28% ihirangi:e rua nga momo tukanga o te whakamaroke pahū me te whakamaroke rehu, te wai na roto i te tātari anga pereti, te wai e kore e rewa i te rua o nga mea iti, no nga hua PAC teitei, ka taea te whakamahi mo te maimoatanga parakaingi iti me te whakato wai tap pretreatment.

30% ihirangi:e rua nga momo whakamaroke pahū me te whakamaroke rehu, he wai mama ma roto i te tātari anga pereti, no nga hua PAC teitei, e whakamahia ana i roto i te tipu wai tap me te iti o te kopouri o te maimoatanga wai whare.

32% ihirangi:ka mahia tenei ma te whakamaroke rehu, he rereke mai i etahi atu hua, he ma te ahua o te PAC, he maamaa teitei kore-ferrous polyaluminum chloride, te nuinga e whakamahia ana i roto i te ahumahi matū pai me te hanga whakapaipai, no te kai kai.

Polyacrylamide:ka kiia ko PA M, e mohiotia ana ko te flocculant, coagulant ranei

Kaupapa:Ko te mekameka ngota PAM me te wahanga marara ma te maha o nga paanga miihini, tinana, matū me etahi atu paanga, ko te wahanga marara e hono tahi ana, ka hanga he whatunga, na reira ka whakanui ake i te mahi.

Mahinga:Ko te PAM he paura ma, he memeha ki te wai, tata kore e rewa i roto i te benzene, ether, lipids, acetone me etahi atu momo whakarewa pararopi whanui, polyacrylamide wairewa wai he tata marama te wai whakapouri, he taonga kore-kino, kore-paitini, kore-waikura, totoka. He hygroscopicity te PAM, ka piki te hygroscopicity ki te piki o te tohu katote.

Te whakarōpūtanga noa

Ko te PAM i runga i ona ahuatanga o te roopu wehewehe ka wehewehea ki te polyacrylamide anionic, polyacrylamide cationic me te polyacrylamide kore-ionic.Polyacrylamide katote.

PAM Cationic:paraka whakahoahohia e te tikanga matū koiora

PAM Anionic:parakaingaki me te paraka me te utu pai, penei i te tipu rino, te tipu hiko, te whakarewa, te horoi waro, te tango puehu me etahi atu parapara, he pai ake te painga.

PAM nonionic:no te mea he pai te paanga o te cationic me te anionic, engari he tino utu te utu o te waeine, kaore i te whakamahia nuitia

Ka taapirihia nga tohutohu e rua hei whakamahi

He aha te flocculation? I muri i te tāpiri coagulant ki te wai mata, tino ranu ki te tinana wai, te nuinga o nga poke colloid i roto i te wai ngaro pūmautanga, a ka tukituki nga matūriki colloid iu, me te whātata ki a ratou i roto i te puna flocculation, a ka hanga i te floc ka taea te tango ma te tikanga rerenga.

Ko nga mea whakaawe o te kapo

Ko te tukanga o te tipu floc ko te tukanga o te whakapiri me te tukinga o nga matūriki iti.

Ko te kounga o te hua o te flocculation ka whakawhirinaki ki nga mea e rua e whai ake nei:

1 te kaha o nga matatini polymer i hangaia e te hauwai coagulant ki te hanga piriti anga adsorption, e whakatauhia ana e nga ahuatanga o te coagulants

2 te tūponotanga o te tukinga o nga matūriki iti me pehea te whakahaere mo te tukinga whaitake me te whai hua. E whakapono ana nga tohungatanga miihini maimoatanga wai kia nui ake te tupono o te tukinga, me whakanui ake te rōnaki tere, me te whakapau kaha o te tinana wai. ka piki ake ma te whakanui ake i te rōnaki tere, ara, te whakanui ake i te tere o te rere o te puna kaukau (addendum: ki te whakahiato nga matūriki me te tipu tere i roto i te kahui, ka ngaro. E rua nga raru: 1 te tipu o te floc he tere rawa tona kaha. ngoikore, i roto i te tukanga rere tutaki kaha kutikuti ka meinga te piriti anga adsorption kua tapahia atu, te tapahi atu adsorption piriti anga he uaua ki te haere tonu ake, na ko te tukanga flocculation he iti te tukanga, ki te tupu o te floc, kia rere tere. kia whakahekehia, kia kore ai e ngawari te pakaru o te kahui i hanga; ka tino heke te tūponotanga, he uaua ki te tipu ake, kare e taea e enei matūriki anake mo te tank parataiao e mau tonu ana, he uaua hoki ki te pupuri mo te tātari.)

Tāpirihia ngā whakaritenga

I te timatanga o te tauhohenga o te taapiri i te coagulant, he mea tika kia nui ake te tupono ki te pa atu ki nga parakaingaki ka taea, te whakanui ake i te whakaranu, te rerenga rere ranei.I runga i te tukinga o te rere o te wai me te pereti whakakopa me te rere o te wai i waenga. pereti whakakopa ki te whakapiki ake i te tere, kia nui haere te matūriki wai tukinga whai wāhitanga, kia te condensation floc.A ki te mutunga o te tauhohenga, i roto i te tikanga ki te whakaiti i te rōnaki tere, ka taea te tiki flocculation pai, pānga rerenga.

Te taapiri taputapu:ipu tarukino, taika rokiroki tarukino, whakakorikori hota, papu tota me nga taputapu ine.Kua rite ki te whakamahi tikanga

PAC, PAM dispensing concentration (tangohia mai i te putea tarapi tarukino me te tapiri ki te tank dissolution) PAC me PAM dispensing concentration E ai ki te wheako: PAC dissolution pool concentration of 5% -10%, PAM concentration of 0.1% -0.3%, the raraunga i runga ake i roto i te ōwehenga ki te kounga, e ko, ia wai pūtoru PAC 50-100kg, PAM 1-3kg. He āhua teitei tenei kukū, PAM te kaha rewa te iti, me ki te whakaoho tino whakaoho tere reo ki te tino memeha.I te raumati, Ka taea te tika te whakanui ake i te kukū rewa PAM ki te 0.3-0.5%.Tangohia te kukū whakakorenga o te PAC o 10%, te kukū whakakorenga PAM o te 0.5%, katahi ka rewa nga wai pūtoru katoa PAC100kg, PAM5kg, whakatikahia te rere o te mita mita diaphragm, kia rite ki te 1 mita pūtoru. /24 haora tātaitanga, ara, Q = 42 rita / haora, ka taea te whakatutuki i te hua pai mo te maimoatanga parakaingaki.PAC, PAM te inenga a nga kaihoko maimoatanga parakaingaki (kua memeha ki te wai taketake) Ko te nuinga o te waa PAC 50-100ppm, PAM 2-5ppm, kotahi miriona te waeine ppm, no reira ka huri ki te 50-100 karamu o te PAC mo ia tana para paru, 2-5 karamu o te PAM, e taunaki ana kia rite ki tenei whakamatautau inenga. Ki te 2000 mita pūtoru te kaha o ia ra mo te maimoatanga parakaingaki, PAC inenga inenga i runga i te 50ppm, PAM inenga inenga kia rite ki te tatauranga 2ppm, na ia ra PAC inenga he 100kg, PAM inenga ko 4kg. Ko te inenga i runga ake ka tatauhia i runga i nga wheako whanui, ko te inenga motuhake me te kukume inenga me whai i runga i te whakamatautau motuhake o te kounga wai.Tātaihia te uara kua whakaritea i roto i te mita rere papu tota

I muri i te taapiri i te kaihoko ki te parakaingaki, ki te paru ranei, me uru pai.Ko te wa whakaranu ko te tikanga 10-30 hēkona, te tikanga kaua e neke ake i te 2 meneti.Ko te inenga motuhake o te kaihoko me te kukū o nga matūriki colloidal, te totoka iri i roto i te parakaingaki, i te paru ranei, he hononga nui te ahua me nga taputapu maimoatanga, te inenga maimoatanga para ki etahi, ka riro te inenga pai ma te maha o nga whakamatautau. te kukū inenga pai (ppm1 ki te tāpiri i te kukū) me te rere wai (t/h) me te whirihoranga o te kukū otinga (ppm2 kukū whakarite), ka taea te tatau i runga i te uara whakaatu rerenga rerenga tota (LPM).Ko te uara whakaatu o te inenga rerenga papu (LPM) = rere wai (t/h)/60×PPM1 ki te tāpiri kukū / PPM2 kukū whakarite.

Tuhipoka: Ko te ppm te kotahi miriona; ko nga waeine uara inenga rerenga papu, LPM he rita/meneti; Ko te GPM he karani/meneti
