I te aroaro o te pikinga ake o te parahanga taiao, kua noho te maimoatanga waipara hei wāhanga nui o ngā mahi tiaki taiao o te ao. Nā te whanaketanga tonu o te hangarau, kua puta te hikohiko hei tikanga tino whai hua, ka taea te whakahaere, me te hoa-taiao mō te maimoatanga waipara ahumahi, waipara whare, me ngā poke rauropi ātete. Kei te ngākau o tēnei tukanga ko te pūtake hikohiko, e mahi ana hei "pūrere matua" e whakarite ana i te tuku pūngao pumau me te tika. Ka tūhuratia e tēnei tuhinga ngā mātāpono mahi, ngā painga, ngā horopaki tono, me ngā whakaaro hoahoa o ngā pūtake hikohiko i roto i te maimoatanga waipara.
1. He aha i hiahiatia ai ngā Pūnaha Hiko Hiko mō te Maimoatanga Wai Para
Ko ngā tikanga maimoatanga wai para ka whakarōpūtia whānuitia ki ngā tukanga ā-tinana, ā-matū, me ā-koiora. Kei roto te hikohiko i te kāwai hikohiko, ā, ka whakahaerehia mā te whakamahi i te iahiko hiko hei whakaoho i ngā tauhohenga waikura, whakaiti, whakatōtō, pirau rānei ki ngā poke.
Hei whakatutuki i ēnei pānga, me whakahaere tika, pumau hoki te iahiko me te ngaohiko mō te tukanga — koinei te wāhi e uru mai ai te pūtake hiko hiko. Ka whakaratohia te pūngao hiko me ngā tikanga whakahaere tika e tika ana hei whakatau i te tere tauhohenga, te whai huatanga, me te kounga maimoatanga whānui.
2. Te Mātāpono Mahi o ngā Pūnaha Hiko Hikohiko i roto i te Maimoatanga Wai Para
Ko te maimoatanga hiko o te wai para e whakawhirinaki ana ki te waikura anodic, te whakaiti cathodic, me te electrocoagulation hei tango, hei whakaputa ke rānei i ngā matū kino i roto i te wai.
(1) Tauhohenga Anodic:
I te anode, ka tukuna ngā irahiko, ka puta ngā matū whakahāora kaha (pērā i ngā rauropi hydroxyl ·OH me te hāora O₂), e whakahāora ana, e whakangaro ana hoki i ngā poke waro.
(2) Tauhohenga Katorika:
I te katote, ka mimitihia ngā irahiko, ka whakaitihia, ka maturuturuhia hoki ngā katote konganuku, ā, ka tangohia ngā konganuku taumaha i roto i te wai para.
(3) Pānga Whakapūngao Hiko:
I te wā o te electrolysis, ka tukuna ngā katote konganuku pēnei i te Fe²⁺ me te Al³⁺ ka waikuratia ki roto i te wai hei hanga i ngā flocculants. Ka mimiti, ka whakatau hoki ēnei flocculants i ngā poke, ka tutuki ai te wehenga me te purenga whai hua.
3. Whakamutunga
He mea nui te mahi a ngā pūhiko hikohiko i roto i ngā pūnaha maimoatanga wai para o ēnei rā. Mā te whakarite i te putanga pumau, te whakahaere tika, me te whai huatanga o te pūngao, ka taea e ngā tukanga hikohiko te whakaheke i ngā poke, te tango i ngā konganuku taumaha, me te whakarei ake i te whai huatanga o te maimoatanga whānui. I te mea kei te piki haere te whakamahi a ngā ahumahi i ngā hangarau matomato me te pumau, e tika ana kia whānui ake te whakamahinga o ngā pūhiko hikohiko i roto i ngā mara maimoatanga wai para matatau me te whakaora taiao.
