Te Polyaluminium Chloride i roto i te Whakatipu Ika: Ngā Painga, te Inenga me ngā Tikanga Pai (Aratohu 2025)

He nui ngā whakaritenga mō te kounga o te wai i roto i te umanga wai, nō reira me tukatuka wawe ngā mea rauropi me ngā poke i roto i te wai ahuwhenua ika. Ko te tikanga maimoatanga tino noa i tēnei wā ko te pure i te kounga o te wai mā teNgā mea whakapūkara.

I roto i te paru wai i hangaia e te umanga ahuwhenua ika, he iti noa ngā momo poke, he iti noa ngā panonitanga o te ihirangi, ā, he iti te whakamahinga hāora i roto i ngā tukanga matū koiora. Hei whakatutuki i ngā whakaritenga o ngā paerewa tukunga me te whakapai ake i te taiao ahuwhenua ika, ka taea e te whakamahinga o te polyaluminium chloride te whakatutuki i te hua o te kounga wai purenga.

Pūhaumāota polyaluminiumHe mea nui tēnei i roto i te mahi ahuwhenua ika, ā, he maha āna mahi:

1. Ka taea e te PAC te whakapai ake i te kounga o te wai, te whakanui ake i te hāora rewa i roto i te wai, me te aukati i te eutrophication.

2. Ka taea te tango i ētahi mate urutā me ngā huakita e piri ana ki ngā totoka iri i roto i ngā wai

3. Ina nui rawa ngā mea rauropi i roto i te wai, he mea tino nui te tikanga whakatau i ngā mea rauropi i roto i te wai, ā, ko te whakamahinga o te polyaluminum chloride tētahi o ngā kōwhiringa whai hua.

4. Te tukatuka wai hiku whakatipu: He nui ngā mea rauropi kei roto i te kounga wai o te whakatipu puna, pērā i ngā toenga whakatipu me ngā paru ika, ka heke te mārama o te wai, ka heke te kounga o te wai. Ka pāngia te taiao e te tukunga tika. Me tātari, me pure te wai whakatipu puna, kātahi ka tukuna, ka hangarua rānei i muri i te tutuki i ngā paerewa tukunga. Mā te whakamahi i te polyaluminum chloride ka tere te whakapūpū, te whakakotahi, me te whakapūpū i ngā matūriki colloidal e uaua ana ki te whakapūpū hei matūriki nui ake, ka whakapūpū ki roto i te wai, ka tino whakaiti i te COD me te BOD o te tinana wai, ā, ka tino whakapai ake i te whai huatanga o te maimoatanga wai hiku.

He pai te polyaluminum chloride mō te wai mata o ngā momo paru rerekē me ngā pāmahana rerekē me te whānuitanga pH whānui.

Me mōhio me whakamahi te polyaluminium chloride i te nui e tika ana. Mēnā ka nui rawa te whakamahinga, ka ngoikore te pānga o te rere o te wai, ā, ka ārai pea i ngā pihanga o te ika me te kōura, ā, kāore e pai mō te whakamahinga roa. I te wā anō, me hono tahi me te rerenga waipara kia puta ai ngā putunga o te polyaluminium chloride i roto i te puna kia taea ai te tango tuturu.
