Polyaluminium pūhaumāota (PAC) ko te ahua o te rauemi purenga wai, inorganic coagulant polymer. E ai ki tona ahua, e taea kia kōmakatia reira rite: puka mārō, me te wai. Ko te puka mārō kua te tae kōwhai kōwhai pouri ranei, parauri pouri, pouri te tae kāpia-rite hina. Ko te wai te aroaro rite te huitahi, mārama, paku kōwhai, kōwhai marama ki te tae parauri. PAC i te tono o ngā tae rerekē, me te hanga hangarau hoki he rerekētanga he ahua o te purenga wai tino whai hua, waihoki te i whakamahia i roto i te purenga o te wai inu, te wai ahumahi, ahumahi wai tohanga, me te mimiti, me te wai poke i ahumahi rongoā, pepa hanga ahumahi me tā, me te mate ahumahi, me te ora maumauria wai.

Polyaluminium pūhaumāota (PAC) mo te ururua maimoatanga wai
Tono
Urban pana wai purenga: te wai awa, wai awa, manawa whenua.
Municipal Wastewater Treatment
Industrial puunaha maimoatanga: tae puunaha, hiako puunaha, puunaha kei roto pūkōwhai, whakarewa taimaha wai ururua, ngaa puunaha, puunaha, waro horoi puunaha, toku waikeri, malu'aki mai puunaha, metallurgy puunaha, tukatuka kai puunaha, maimoatanga parakaingaki.
Ahumahi puunaha me ngā rauemi whakarewa ururua hangarua
Pōkai & Tukunga:
PAC hoki te wai inu: 25KG kupenga taimaha peke whatu, 20-22MT ia 20 waewae ipu uta.
PAC mō te wai ahumahi: 25KG kupenga taimaha peke whatu, 25MT max ia 20 waewae ipu uta.
PAC Paura Polyaluminium pūhaumāotamo Taone parakaingaki Treatment
Polyaluminum pūhaumāota ko te rauemi purenga wai, he coagulant polymer pararopi, me te polymer ki te taimaha rāpoi āhua nui, me te tiaki ngā tiketike o te waerau pararopi whakaputaina e te mahi piriti o katote hydroxyl me te polymerization o ngota tīhiko polyvalent. Rongoā. I roto i te puka, e taea te wehea te reira ki e rua momo: mārō, me te wai. Kua wehea nga totoka ki parauri, kirīmi, koura kōwhai me te ma kia rite ki te tae rerekē, a taea te māngai te wai rite te huitahi, mārama, kowhai, marama kōwhai ki kōwhai-parauri.
Ko te nuinga te pūhaumāota polyaluminum he ihirangi o te konumohe ōkai i waenganui i 27 me 30 khaki-kōwhai paura totoka kōwhai. Enei momo o te pūhau polyaluminum i te memehatanga āhua pai te wai, a i roto i te akoranga o te whakakāhoretanga, huringa physicochemical pērā i iahiko, agglomeration, adsorption, me te rerenga te mutunga arahi ki [Al2 (OH) 3 (OH) 3] rerenga, reira whakatutuki i te whakaaro o purenga. I roto i te whakamahi o te polyaluminum pūhaumāota, i waho te hiahia mo te tahi atu tāpiritanga, hanganga floe he nohopuku, me te matotoru, mahi nui, ngā rerenga tere, me te mārama pānga i runga i turbidity tiketike purenga wai.
Ko te rauemi raw o te pūhaumāota polyaluminum kōwhai he konupūmā aluminate paura, waikawa pūmāota, bauxite, te nuinga whakamahia hoki maimoatanga parakaingaki me te inu maimoatanga wai, ki te te rauemi raw mō te inu maimoatanga wai he konumohe waihā paura, te waikawa pūmāota, a paku Paura aluminate konupūmā, pereti me te pēhanga anga tukanga filtration tukanga whakamaroke rehu ranei i whakaritenga tino i runga i konganuku taimaha i roto i te whenua maimoatanga wai inu, na e rua ngā rauemi raw me ngā tukanga production he pai atu tan PACs.
Ko te rauemi raw mō te pūhaumāota konumohe polyaluminum tan he konupūmā aluminate paura, te waikawa pūmāota, bauxite me te paura rino. Kei te nuinga whakamahia te reira mo te maimoatanga parakaingaki no te mea kei roto te reira i paura rino na he tan te tae. Kei te tapiritia te atu paura rino, te mumura ko reira. Ki te nui ake te paura rino tetahi nui tetahi, kei te te tahi mau taime i huaina reira polyaluminum pūhaumāota rino. , He hua pai i roto i te maimoatanga o te parakaingaki.
Kukū tikanga ōwehenga:
1. E ai ki te āhuatanga o te wai raw, mahi he whakamātautau iti i mua i te whakamahi i ki te whiwhi i te horopeta pai. Iti otinga whirihoranga whakamātautau i te ōwehenga taimaha (W / W), te tikanga 2-5% ki te pai. Huihui ki 3% otinga: ka mea polyaluminum pūhaumāota PAC 3g totoka, ki te puoto ruri 200mr, tāpiri e pā ana ki 50mR o te wai, rewa ki te kia a ka diluted ki te wai ki te tauine 100mr, ruru ai.
2. A, no te whakaputa polyaluminum pūhaumāota PAC mo te hanga, uru me te tareka rite ki polyaluminum pūhaumāota PAC totoka: wai = 1: 9 ki te 1:15 ōwehenga taimaha. E pängia ana ki te paparetanga Solutions ki te ihirangi o te alumina iti iho i te 1% me taea whakaiti i te pānga o te whakamahi. He tiketike rawa ki te kia ngāwari tāpiri whakanoho nohanga.
3. Dosing rite ki te nui dosing pai whiwhi i te whakamātautau iti. Hei tauira, ki te e kitea tāke parataiao ki te kia iti, ki te reira e nui moni o turbidity, ka kia iti rawa te inenga. Ki te he nui, me te a Aoraki ki te tank te parataiao me he tiketike te toe turbidity, he nui rawa te nui o te dosing me kia hanga whakarerekētanga.
Polyaluminium whakamahi pūhaumāota tikanga:
I muri rewa te hua totoka i roto i te wai i te 1: 3, kua whakamahia te reira rite te wai, diluted ki 10-30 wa o te wai hou ki te kukū e hiahiatia ana. Ko te uara PH tino pai mo te dosing ko 3.5-5.0, a kua tapiritia te uara PH pai ki te whakanui i te hua o te coagulation. Ka taea te whakaritea i te inenga rite ki te turbidity rerekē o te wai raw, ka takoto te inenga pai te. A, no te te turbidity wai raw he 100-500mg / L, te inenga ia kiloton he 10-20kg. A, no te he tiketike te turbidity o te wai raw, kei te tika nui haere te inenga, me ka he iti te turbidity, e taea te tika heke te inenga.
Ko te inenga o te pūhaumāota polyaluminum i roto i te kounga rerekē te wai:
Tuatahi, i roto i te wai turbidity iti, diluted te hua polyaluminum pūhaumāota totoka te 1: 3 (ōwehenga taimaha) me pato wai me whakaohokia noa tino memeha.
Tuarua, i roto i te ora, me te hanga whakamahi o te parakaingaki, ki tohutoro ki ia ton o parakaingaki i mua i te tāpiri e pā ana ki 30g o ngā hua polyaluminum pūhaumāota. Na ka tāpiri i te hua polyacrylamide diluted (ki te he e kore e kitea te pānga, tēnā whakaiti ake i te inenga hua rite tika ana ranei).
