He aha ngā mea ka taea te whakamahi hei whakakapi i te polyaluminum chloride i roto i te maimoatanga waipara?

I roto i te maimoatanga waipara, Pūhaumāota Polyaluminium (PAC) e whakamahia whānuitia ana, engari ka taea te whakaaro ki ēnei huarahi kē atu i roto i ngā horopaki motuhake (pēnei i te whakaiti i ngā toenga konumohe, te urutau ki te kounga wai pāmahana iti, te whakapai ake rānei i te utu):

Ⅰ. NGĀ HUARAHI WHAKAPĀWERA

te pūkawa polyferric (Ngā Pfs)

● Ngā Painga: He kaha ake te urutau ki te taiao pāmahana iti (kei te whai hua tonu i te 4℃), he tere te whakatō, kāore he mōrearea o te toenga o te katote konumohe, he pai mō te maimoatanga wai inu;

● Ngā āhuatanga e tika ana: ngā wai parapara he nui te paru, ngā wai parapara hinuhinu me ngā wāhi e hiahia ana kia tino tirotirohia te konumohe (pērā i ngā pūnaha wai);

●Utu: 30-50% te iti iho i te horopeta PAC, ā, he pai ake te mahi whakamaroke paru.

Konumohe rino polychloride (PAFC)

● Ngā Āhuatanga: me ngā painga o te tote konumohe me te tote rino, he iti ake te kikī o te pua konumohe, he tere te tere o te whakatō, he pai mō ngā wai para nui te paru/pāmahana iti;

● Te whānuitanga o te whakamahinga: wai para ahumahi (hei tauira, te tā me te tae, te hanga pepa), te puna wai pāmahana iti me te wai pōuri iti.

Ngā kaihoko kore-waro tuku iho

● Konumohe whanariki: he iti te utu, engari he ngoikore ake te pānga o te whakapūkara i te PAC, me whakamahi tahi me te āwhina whakakōkī;

● Raima (CaO): e whakamahia ana hei whakatika i te pH me te tango i te whākawa, engari he nui te paru e puta mai ana, nō reira me whakakotahi me ētahi atu matū.

II. Ngā Huarahi Rēwena me ngā Huarahi Whakakotahi

Polyacrylamide (PAM)

● Mahi: He maha ngā wā ka whakamahia hei āwhina whakapūmau me te PAC. Mēnā ka whakamahia takitahi, me whiriwhiri kia rite ki te kounga o te wai (cationic/PAM mō te whakamaroke paru);

● Ngā Here: Kāore e taea te whakakapi katoa i te mahi toto totoka o te PAC, ā, me whakamahi tahi me ngā kaihoko kore-waro.

Kaiwhakarewa whakakotahi

● PFS+PAM/PAM whakarerekētia: whakapai ake i te whai huatanga o te maimoatanga wai para kei roto he hinu, me te whakaiti i te nui katoa o ngā matū;

● He wai whakapūkara taiao kei roto i te chitosan/gelatin: he pai mō te tukatuka kai i ngā wai para, he haumaru teitei engari he utu nui.

Hangarau pateni hou

● Whakakī hiato aukume + whakaiti PAC: ka whakarei ake te kaha mimiti me te kaha whakaahua-whakakorikori mā te utaina o te waikura rino, ā, ka whakaitihia te nui o te PAC mā te neke atu i te 30%.

Ⅲ. Ngā kōwhiringa mahi motuhake

Ngā kaihoko dedrophilic

● Te tote raima, te tote konupūmā rānei: he tikanga matū mō te tango i te whākawa, engari ka piki ake pea te pakeke o te wai;

● Tote rino (hei tauira, PFS): te tango i te whākawa me ngā konganuku taumaha i te wā kotahi, he pai ake i te tote konumohe.

Te tango tae me te whakahekenga COD

● Kaiwhakakore tae motuhake + ferrous sulfate: mō te tae i ngā wai para, whakakapia te mahi whakakore tae o te PAC.

Ⅳ. Ngā taunakitanga mō ngā kōwhiringa rerekē

ngā take e tika ana kia arohia:

● I mua i te whakakapinga, me whakatau te horopeta me te awhe pH pai rawa atu mā te whakamātautau whakamātautau (hei tauira, he pai te PFS mō te pH 4-11, ko te PAC he 5-8);

● Me arotake te toenga o ngā matū kei roto i te konumohe (pēnei i te PAC me te PAFC), inā koa i roto i ngā wai e pāngia ana e te taiao;

● Tērā pea ka whakanui ake te matū whakahiato i te nui o te paru, nō reira me arotau te tukanga whakamaroke.
