Hangarau Hanga Hopi Hopi Taiao
Kei te tipu haere tonu te mōhiotanga o te marea ki te parahanga wai, ngā para o te whare, me ngā tapuwae waro ahumahi. Ko tētahi hua e pā tata ana ki te oranga o ia rā e whai wāhi ana ki te taumahatanga taiao ko te hopi horoi. Ka whakamahia ngā hopi horoi hei horoi kākahu, hei horoi taputapu o te whare, tae noa ki ngā mahi ahumahi. Mena kāore i te pai te hoahoa o ā rātou tukanga hanga me te hanga, ka whai wāhi ngā hopi horoi ki te whakamomona wai (te puāwaitanga o te rimurimu), te paitini ki ngā rauropi wai, me te whakaputa i ngā toenga e uaua ana ki te pirau. Nō reira, kua noho te hangarau hanga hopi horoi taiao hei kaupapa nui, e whakakotahi ana i te matū matomato, te hangarau tukanga, me te whakahaere i te huringa ora o te hua.
1. He aha i hiahia ai kia pai ake te hanga i ngā hopi horoi kia pai ake ai te taiao?
Ko ngā hopi horoi tikanga he mea hanga ki ngā matū horoi wai, ki ngā kaihanga (ngā mea here konupūmā/konupora), ki te mā, ki ngā kakara, me ngā momo tāpiri. Ko ētahi o ngā raruraru matua o ngā hopi horoi "tawhito" ko: te whakamahinga o ngā phosphate hei kaihanga, e whakaoho ana i te eutrophication; ngā matū horoi wai he uaua ki te pirau, ā, nō reira ka mau tonu ki ngā pūnaha rauropi wai; me te whakamahinga o ngā tāpiri e whakanui ana i te paitini, e whakaputa ana rānei i ngā hua taha kino. Hei tāpiri, ko te tukanga whakaputa e nui ana te pūngao me te whakaputa tukunga ka whakanui ake hoki i te pānga ki te taiao.
Ehara i te mea ko te tikanga o ngā hopi horoi taiao he "ngawari te pirau", engari kei roto hoki ko ngā rauemi mata pumau, ngā tukanga whakaputa iti-pūngao, he iti noa te para, he haumaru mō ngā kaiwhakamahi, ā, he whai hua ina whakamahia i ngā pāmahana iti, ā, nā reira ka penapena pūngao i te wā tono.
2. Auahatanga rauemi mata: ngā matū horoi matomato
Ko te ngako o ngā hopi horoi ko ngā matū horoi—ngā ngota e whakaiti ana i te taumahatanga o te mata o te wai, e āhei ai te tango atu i te paru hinuhinu. Ko ngā hangarau hoahoa taiao e aro nui ana ki ngā matū horoi i ahu mai i ngā pūtake hou, ā, he tino pirau.
a. Ngā matū horoi i runga i te hinu huawhenua (ngā matū oleo)
He maha ngā hopi horoi hou e tīmata ana ki te whakamahi i ngā rauemi mata mai i te hinu kokonati, te hinu pata nikau, ētahi atu hinu huawhenua rānei. Hei tauira, ko ngā waipiro ngako, ka hurihia hei surfactants pērā i te waipiro ethoxylates (i raro i ngā tukanga whakahaere) me ngā alkyl polyglucosides (APG). Ka hangaia ngā APG mā te tauhohe i te huka (glucose) me ngā waipiro ngako, ka puta he surfactants kore-ionic ka pirau i te nuinga o te wā, ā, he ngawari ki te kiri.
b. Ngā matū whakaora koiora mai i te whakapūkara
Mā te hangarau whakapūkara ka taea te whakaputa i ngā matū koiora pēnei i te rhamnolipids, te sophorolipids, me ngā lipopeptides mā te whakamahi i ngā moroiti. Ko ō rātou painga ko te pirau nui me te mahi pai i raro i ngā āhuatanga motuhake (hei tauira, te tote, te pH rānei). Kei te mau tonu ngā wero i roto i te tauine whakaputa, te pumau, me te utu. Heoi, me ngā whanaketanga o te tukatuka koiora—te arotau i te momo, te whakahaere whakapūkara, me te purenga—kei te piki haere te whai hua o ngā matū koiora mō ngā tono arumoni.
c. Ngā matū horoi me te hoahoa pirau-koiora
Haunga "te pūtake mai," he mea nui anō hoki te hoahoa ngota. Ko te mātāpono he ngāwari ake te pirau o ngā mekameka hauwaiwai rārangi i ngā mekameka peka. Kei te whakawhanake ngā kaihanga i ngā matū horoi e ngāwari ake ai te pakaru e ngā moroiti i roto i ngā whare tukatuka wai para.
3. Te whakakapi i te phosphate: kaihanga hoahoa taiao
Mā ngā kaihanga e āwhina ki te whakangawari i te wai mā te here i ngā katote konupūmā me te konupora, kia pai ai te mahi a ngā matū horoi. I rongonui te phosphate i mua mō tōna whai huatanga, engari ka taea e ia te arahi ki te eutrophication. Ka whakamahia e te hangarau hopi horoi taiao ētahi atu huarahi pēnei i:
– Te zeolite (aluminosilicate): ka hopu i ngā katote konupūmā, ā, he whai hua ki roto i ngā paura hopi horoi.
– Konutai citrate: i ahu mai i te waikawa citric (ka taea te whakaputa mā te whakapūkara), he ngāwari te pirau, ā, he haumaru hoki.
– Konutai kāponāte (houra horoi): ka āwhina ki te whakanui ake i te kawakore me te mahi horoi.
– Ētahi polycarboxylates: e whakamahia ana i roto i ngā kukū kua whakaritea hei āwhina i te marara o te paru me te ārai i te whakatakotoranga anō.
Kei te ārahi hoki ngā whanaketanga ki ngā kaihanga e whai hua ana i ngā horopeta iti ake, ā, ka whakaitihia te nui o ngā matū e maumauria ana.
4. Ngā whākōkī: he horoi whai hua i ngā pāmahana iti
Ko tētahi o ngā huarahi tino kitea hei whakaiti i te pānga ki te taiao ko te whakaiti i te whakapaunga pūngao i te wā e horoi ana. Mā ngā whākōkī pēnei i te protease, te amylase, te lipase, me te cellulase ka taea e ngā hopi horoi te mahi pai i ngā pāmahana iti (hei tauira, 20–30°C). Mā tēnei ka penapenahia te hiko, te hau rānei e whakamahia ana mō te whakamahana i te wai.
Ko te hangarau whākōkī e whai wāhi ana ki:
– Te whakau i ngā whākōkī kia ātete ai ki ngā waikura me ngā huringa pH.
– Te whakakīkī i ngā whākōkī hei tiaki i ngā whākōkī i te wā e rongoa ana, hei whakaiti hoki i te puehu (he mea nui mō te haumaru o ngā kaimahi me ngā kaiwhakamahi).
– Whakapaipaihia te hanganga kia mahi tahi ai te whākōkī me te matū horoi me te kaihanga.
5. Ngā mea whakama me ngā mea whakamārama haumaru ake
He whai hua ngā whakamaeneene chlorine (hei tauira, hypochlorite) engari ka taea te hanga i ngā hua taha kino. Ko ngā hopi horoi taiao e whakamahi ana i:
– Te hāora i ahu mai i te percarbonate/perborate (kei te piki haere te here o te perborate i ētahi wāhi nā ngā take boron), me te TAED hei whakahohe kia whai hua ai i ngā pāmahana iti.
– Ka tīpakohia ngā whakakanapa whatu me te whai whakaaro ki te pirau koiora me te pānga ki te paitini taiao, ā, kia iti rawa te whakamahinga.
6. Hangarau tukanga whakaputa: te whai huatanga o te pūngao me te iti o te para
Ehara i te mea ko ngā tohutao anake te mea e pā ana ki te taiao, engari ko ngā hangarau hanga anō hoki.
a. Te hanga hopi paura: te whakamaroke rehu me te whakakotahitanga
Ko te tikanga matarohia mō te hanga hopi paura ko te whakamaroke rehu, arā, ko te rehu i te paru ki roto i te pourewa whakamaroke me te hau wera. He nui te kaha e pau ana i tēnei. Ko tētahi atu huarahi whai hua ko te whakaranu maroke me te whakakotahi (whakapūhui): ka whakaranua ngā kai, ka whakapūhuitia, ka whakaitihia te hiahia mō te whakamaroke. Ka whakaitihia e tēnei hangarau te whakapaunga kaha me ngā tukunga, me te whakaputa i ngā pūhui tere rewa.
b. Ngā hopi horoi kukū me ngā hopi horoi tino kukū
Ko te whakamātotoru i te hua ko te whakaiti i te wai me te whakakī, nō reira:
– he iti ake te takai,
– te māmā ake o te kawe waka (he iti ake ngā tukunga),
– te whakaiti i ngā whakaritenga pūngao mō te whakaputa me te kawe waka.
Ka kitea tēnei ia i roto i ngā hopi horoi wai kukū, ngā kāpū/ngā pūwero, me ngā paura horoi tino mahi me ngā horopeta iti.
c. Te whakahaere tukunga me te whakamahi anō i te wai tukatuka
Kei ngā wheketere hou ngā pūnaha wai porowhita-katia, te whakaora i te wai whakapūhau, me te maimoatanga hau putanga (hei tauira, te hopu puehu/matūriki). Ka tukatukahia te wai para hei whakaiti i te COD/BOD i mua i te tukunga, ā, ka taea te whakamahi anō i ētahi awa para.
7. Te hoahoa o ngā takai me ngā hua: te whakaiti i te kirihou me te whakanui ake i te hangarua
He nui te takoha a te takai ki te tapuwae taiao. Ko ngā mahi auaha hou ko:
– teihana whakakī anō, whakakī anō rānei hei whakaiti i ngā pounamu whakamahi kotahi,
– te whakamahinga o te kirihou hangarua (PCR) me te hoahoa rauemi kotahi mō te hangarua ngāwari,
– ngā tapanga me ngā waituhi e hototahi ana ki ngā tukanga hangarua,
– ngā kāpū hopi horoi me te kiriata wairewa-wai kua hangaia kia haumaru, kia pirau hoki, me te aro nui ki te haumaru o ngā tamariki.
E whai whakaaro ana hoki te hoahoa ki te "horopeta tika." Ko ngā hua kakara rawa, he pahuka rawa rānei, ka nui rawa te whakamahinga, ka maumauria hoki te wai hei horoi.
8. Te whakamātautau pirau koiora me te aromatawai i te huringa ora (LCA)
Hei whakarite kia kaua ngā kereme "hoa-taiao" e waiho hei mahi hokohoko noa iho, ka whakatinanahia e ngā kaihanga ngā paerewa whakamātautau:
– te pirau ā-hauora/ā-waiora kore-hauora,
– te paitini taiao ki ngā mea ora wai,
– te tapuwae waro me te whakamahinga wai mā te Aromatawai Huringa Ora (LCA).
Ka arotakehia e te LCA ngā pānga mai i ngā rauemi mata, te hanga, te tohatoha, te whakamahinga (te wāhanga horoi), me te whakakorenga o ngā takai. He mea whakamīharo, ko te wāhanga whakamahi te nuinga o te wā e whai wāhi nui ana nā te paunga o te pūngao o te whakamahana i te wai. Nō reira, ko ngā hopi horoi e whai hua ana i ngā pāmahana iti, ā, he ngāwari ki te horoi, he maha ngā wā ka tino pai ake i roto i ngā LCA.
9. Ngā wero me ngā huarahi ā muri ake nei
Ahakoa ngā whanaketanga o te hangarau, kei te mau tonu ētahi wero. Me noho utu tika ngā matū horoi me ngā kaihanga matū matomato, me pumau i te wā e rongoa ana, ā, me whai hua hoki puta noa i ngā momo āhuatanga wai (ngawari/mārō) me ngā momo paru. Me whai tauine whakaputa whai hua me te mekameka tuku pumau ngā matū horoi koiora. Hei tāpiri, he rerekē ngā ture me ngā paerewa tapanga taiao puta noa i ngā whenua, e hiahia ana kia whakarerekē ngā kaihanga i ā rātou hanganga.
Hei tirohanga whakamua, ko ngā mahi auaha whai hua ko:
– ngā rauemi mata mai i ngā para koiora (hei tauira, te hinu tunu kai kua whakamahia, ngā toenga ahuwhenua rānei),
– ngā tukanga koiora e whai hua ana ki te pūngao mō ngā matū whakaora koiora me ngā tāpiringa,
– he iti te hanga rauemi, he teitei te mahi (he iti engari he pai ake),
– Te whakaurunga o te AI me ngā raraunga mō te arotautanga o ngā tunu kai me ngā tukanga whakaputa,
– he pūnaha whakakī me te tohatoha e ahu mai ana i te kukū hei whakaiti i te nui o te tākai.
Whakamutunga
Ko te hangarau mō te hanga hopi horoi taiao he whakakotahitanga o te auahatanga rauemi (ngā matū horoi hou, ngā kaihanga kore-phosphate, ngā whākōkī), ngā whakapainga tukanga whakaputa (te whai huatanga o te pūngao, te whakakotahitanga, te kukū), te hoahoa takai, me te aromatawai pūtaiao mā te pirau koiora me ngā whakamātautau LCA. Ko te whāinga matua ehara i te mea ko te hanga i ngā hopi horoi kia "kakariki ake," engari ko te whakaiti nui i te pānga ki te taiao me te kore e whakararu i tā rātou mahi matua: te horoi whai hua, haumaru, me te penapena rauemi. Mā te tautoko o te rangahau, ngā ture tika, me te whanonga whakaaro nui a te kaihoko i roto i te whakamahinga o te inenga me te pāmahana horoi, ka taea e ngā hopi horoi te noho hei tauira angitu o te whakamahinga o te hangarau matomato i roto i ngā hua o ia rā.
