He Aratohu Katoa mō te Maimoatanga Wai Whai Hua
He nui te whakawhirinaki o ngā pūnaha maimoatanga wai ki ngā tukanga whakapūmau me te whakapūpū hei tango i ngā matūriki iri, ngā mea rauropi, me te paru i roto i te wai. Ko ētahi o ngā matū e whakamahia whānuitia ana i roto i ēnei tukanga koPūhaumāota Polyaluminium (PAC)mePolyacrylamide (PAM).
Ina whakamahia tika ngātahi, ka taea e te PAC me te PAM te whakapai ake i te whai huatanga o te whakamārama wai, te whakaiti i te horopeta matū, me te whakarei ake i te mahi taunga paru. Heoi, ko te whakakotahitanga hē—pērā i te raupapa horopeta hē, te kukū rānei—ka taea te whakaiti i te whai huatanga o te maimoatanga.
Kei roto i tēnei tuhinga he aratohu hangarau katoa mō te whakakotahi i te PAC me te PAM i roto i te rongoā toto toto tiketike, tae atu ki ngā mātāpono, ngā tikanga ine, ngā rautaki arotau, me ngā hapa noa hei karo.
Te Mārama ki ngā Mahi a te PAC me te PAM i roto i te Whakapūpūngao
I mua i te matapaki me pēhea te whakakotahi i ēnei, he mea nui kia mārama ki te mahi a ia matū i roto i te tukanga taupū-whakapūpū.
Pūhaumāota Polyaluminiumhe matū whakakōkī pūmua kore-waro e whakamahia whānuitia ana i roto i te maimoatanga wai inu, te maimoatanga wai para ahumahi, me ngā pūnaha wai para ā-tāone.
Ko te mahi matua a te PAC mā te whakakore i te utu me te mimiti. I roto i te nuinga o ngā pūnaha wai taiao, he utu kino ngā matūriki iri, e pupuri ana i a rātou kia marara, kia kore ai e tau. Ka tukuna e te PAC ngā iona konumohe utu pai hei whakakore i ēnei utu. Kia whakakorea, ka tīmata ngā matūriki ki te kohikohi hei ngā moroiti iti.
Ngā Painga o te PAC
- Te kaha toto totoka kaha
- Te tango pai i te paru
- Whānui te whakamahinga pH
- He iti ake te rahinga o te paru i whakaritea ki ngā tote konumohe tuku iho
- He pai mō te wai inu me te wai para
Heoi, ko te PAC anake pea ka hanga i ngā putunga iti ka ata tau, koinei te hiranga o te PAM.
PolyacrylamideHe mea whakapūpū waipara waro te PAM e whakamahia ana hei whakarei ake i te whakapūpū me te taunga. Ko te mahi matua a te PAM mā te hono i te waipara. Ka hono ōna mekameka ngota roa i ngā momo waipara iti maha, ka hanga he waipara nui, he waipara matotoru ka tau tere.
Ngā momo PAM e whakamahia ana i roto i te maimoatanga wai
E toru ngā momo matua:
- PAM Anionic (APAM)
- PAM Kationika (CPAM)
- PAM Kore-ionic (NPAM)
I te nuinga o ngā pūnaha PAC + PAM, ka whakamahia whānuitia te PAM anionic nā te mea kua taea kē e te PAC te whakakore i te utu pai.
Ngā painga o te PAM i roto i ngā pūnaha toto toto tiketike
- Whakanuia te rahi o te floc
- Ka whakatere i te whakatōtōtanga
- Ka whakapai ake i te whakamaroke paru
- Ka whakaiti i te horopeta PAC
- Whakarei ake i te pai o te tātari
He aha i whakamahia ngātahi ai te PAC me te PAM
Mā te whakamahi ngātahi i te PAC me te PAM ka puta he pānga taupū-whakapūpū tahi.
Tikanga taahiraa-i-te-taahiraa
Ka whakararuraru te PAC i ngā matūriki, ka whakakore i ngā utu, ā, ka hanga i ngā moroiti-pūpū.
Ka hono ngā mekameka PAM i ngā moroiti ki ngā moroiti nunui ake.
Ka tere ake te totohu o ngā putunga wai nui i roto i ngā puna whakapūtātanga.
Ngā painga o te whakamahi i te polyaluminum chloride me te polyacrylamide i te wā kotahi
- Te tango i te paru teitei ake
- Te wā whakatau tere ake
- Te iti o te whakamahinga matū
- Te nui o te paru kua whakaitihia
- Te whakapai ake i te mahi tātari
Nā ēnei painga, e whakamahia whānuitia ana ngā huinga PAC + PAM i roto i:
- Ngā whare tukatuka wai para ā-tāone
- Te maimoatanga waipara ahumahi
- Te whakamārama i ngā wai para o te maina
- Te maimoatanga waipara o te mira pepa
- Te whakamārama i te wai inu
Te raupapatanga tika o te horopeta o te PAC me te PAM
Ko tētahi o ngā mea tino nui mō te angitu o te whakapūpū toto ko te raupapatanga o te horopeta. Ko te raupapa tika ko:PAC tuatahi → PAM tuarua
He aha me tāpiri tuatahi te PAC
Me whakakore tuatahi e te PAC te utu matūriki, ā, me hanga he moroiti iti tuatahi. Ki te kore tēnei taahiraa, ka memeha noa ngā ngota PAM ki te wai, ā, kāore e taea te here tika i ngā matūriki.
Ngā taahiraa inenga noa
- Tāke whakaranu tere
- Werohanga PAC
- Te whakaranu tere (30–60 hēkona)
- Werohanga PAM
- Te whakaranu puhoi (wāhanga whakapūpū)
- Te Whakatōtō
⚠️ He hapa noa:He hapa noa te tāpiri i te PAM i mua i te PAC, e hua ake ai te hanganga ngoikore o te floc me te maumauria o ngā matū.
Te Inenga Tino Pai o te PAC me te PAM
Ka rerekē te horopeta i runga i te kounga o te wai, te paru, me te kukū o ngā matū totoka kua whakatārewatia.
Ko ngā awhe noa e whai ake nei
Inenga PAC
Wai inu: 5–50 mg/L
Para wai ahumahi: 30–200 mg/L
Inenga PAM
He iti iho i te PAC te nuinga o te wā
Awhe noa: 0.1–3 mg/L
Ture matua
Ko te horopeta PAM he 1/100 ki te 1/50 o te horopeta PAC.
Ka taea e te nui rawa o te PAM te arahi ki:
- Ngā pūhui piri
- Te noho rawakore
- Te aukati i te tātari
Nō reira, me whakamātautau i ngā ipu hei whakatau i te horopeta tino pai.
Te whakarite i ngā otinga PAC me PAM
He mea nui te whakarite matū tika mō te horopeta pumau.
* Te whakarite i te otinga PAC
Ko te PAC ka whakaritea i te nuinga o te wā hei otinga 5–10%.
Ka tere te memeha o te PAC, ā, ka taea te whakamahi i roto i te rā kotahi.
*Te whakarite otinga PAM
Me tino whakarite kia pai ake te PAM.
Te kukū noa:
0.05–0.1% otinga
Tauira whakarite:
- Tāpirihia te wai ki roto i te tāke whakaranu
- Āta tauhiuhia te paura PAM
- Whakaohokia mārire mō te 30–60 meneti
- Tukua kia pakeke mō te 30 meneti
Ngā tuhipoka nui:
- Āta karohia te whakaranu tere-rahi (tērā pea ka pakaru ngā mekameka polymer)
- Whakamahia te wai mā
- Whakaritea he otinga hou i ia rā
Ngā Tikanga Whakaranu mō te Whakapūngao Whai Hua
He nui te pānga o te kaha o te whakaranu ki te mahi toto totoka.
Wāhanga whakaranu tere
Te kaupapa: te whakamarara tere i te PAC.
Ngā tawhā noa:
- Wā: 30–60 hēkona
- Te pikinga tere (G): 700–1000 s⁻¹
Wāhanga whakapūpū
Te kaupapa: kia tupu ngā putunga witi, kia kore ai e whati.
Ngā tawhā noa:
- Wā: 15–30 meneti
- Te pikinga tere: 20–80 s⁻¹
I te nuinga o te wā ka tāpirihia te PAM i te tīmatanga o te wāhanga flocculation.
Te Whakamātautau Ipu mō te Arotau Tukanga
Ko te whakamātautau ipu te tikanga pono rawa atu mō te whakatau i te huinga PAC me te PAM tino pai.
Te tukanga whakamātautau ipu paerewa
- Whakaritea ētahi tauira wai
- Tāpirihia ngā horopeta PAC rerekē
- Ranunga tere
- Tāpirihia te PAM
- Ranunga puhoi
- Tirohia te hanganga o te floc
- Ine i te paru i muri i te taunga
Ngā kitenga matua:
- Rahi o te floc
- Te tere o te taunga
- Te mārama o te wai
Ko te horopeta tino pai ka puta:
- Ngā pūhui nui
- Tere te taunga
- Wai wai mārama
Ngā Hapa Noa i te Whakakotahitanga o te PAC me te PAM
Ahakoa ngā kaiwhakahaere mohio ka tūtaki ki ngā raruraru i ētahi wā.
Whakamutunga
Ko te whakakotahi i te Polyaluminum Chloride me te Polyacrylamide tētahi o ngā rautaki tino whai hua mō te whakapai ake i te toto totoka me te flocculation i roto i ngā pūnaha maimoatanga wai.
Ka whakararuraru te PAC i ngā matūriki iri mā te whakakore i te utu, ko te PAM ia ka whakarei ake i te hanganga floc mā te hononga polymer. Ina whakamahia i te raupapa tika—ko te PAC tuatahi, ko te PAM tuarua—ka hangaia e ēnei matū he floc nui, he matotoru e tere ana te tau, ā, ka puta he wai mārama.
Hei whakatutuki i ngā hua tino pai, me arotahi ngā kaiwhakahaere ki:
- Te raupapatanga horopeta tika
- Te whakahaere inenga tika
- Te whakarite tika i te otinga
- Ngā āhuatanga whakaranu kua arotauhia
- Te whakamātautau ipu mō te whakatikatika tukanga
Mā ngā mahi whakahaere tika, ka taea e te PAC me te PAM te whakapai ake i te pai o te maimoatanga wai, te mahi taunga paru, me te pono whānui o te pūnaha.
