Kupumatua: Te whakarewa tango tae, te kaihoko tango tae, te kaihanga kaihoko tango tae, Whakakore Tae
I waenganui i ngā awa mārama me ngā moana kikorangi, kei reira tētahi rōpū "kaitiaki kounga wai" kāore i te mōhiotia - he hunga tango tae. Pērā i tētahi kaimahi tunu kai mātau, ka taea e rātou te huri i te "hupa" paru hei wai mārama. Engari he āhua anō tō tēnei "kaimahi tunu kai"; ko te horopeta, te pāmahana, me te tikanga whakaoho katoa e whakatau ana i te hua kounga wai whakamutunga.
1. Inenga: Nui rawa, iti rawa; Ka waipuke te waipuke
Whakaarohia te tāpiri wai i te wā e tunu ana i te parāoa: he iti rawa te wai, ā, ka piri te parāoa ki raro; he nui rawa te wai, ā, ka angiangi, ka kore he reka. Me tino whakahaere hoki te horopeta o te wai whakakore tae. Nā te hiahia o tētahi wheketere kakahu ki ngā hua tere, i whakapiki ake i te horopeta kua tūtohutia mā te 30%, ā, kāore i tutuki te hua e hiahiatia ana, engari i tino matotoru hoki ngā parāoa i tere te taunga, ka taea ai e ngā ngota tae toenga i roto i te wai te taurite anō pērā i te "ika i paheke i roto i te kupenga." Ko tētahi atu wheketere tae, i piri tonu ki te ōwehenga kua tūtohutia o te 0.5‰, i whakatau i te horopeta pai rawa atu mā roto i ngā whakamātautau iti e toru, ā, i te mutunga ka pumau te tae o te para i raro i te 10 nekehanga, ka tutuki i te paerewa tukunga Akomanga I ā-motu.
2. Te Pāmahana: Te Waehere Tere o ngā Tauhohenga Matū
He rite te pānga o te pāmahana ki te pānga whakapūpū o ngā mea whakapūpū tango tae ki te kohua i te hua manu: me manawanui te wai matao, engari ka tere te whakapūpū o te wai kohua. I tētahi mira pepa i te raki o Haina, i te hekenga o te pāmahana o te wai ki te 5°C i te takurua, i whakaitihia e ngā tohunga hangarau te wā whakapūpū mai i te 30 meneti ki te 15 meneti mā te whakahaere i te pāmahana whakarewa o te mea whakapūpū i te 40°C pea, kia whānui ai ngā mekameka ngota. I taua wā, i tētahi tipu whakakikorua hiko i te tonga o Haina, i ngā pāmahana teitei o te raumati, mā te tāpiri i tētahi mea whakaroa ka noho te pāmahana tauhohenga ki raro i te 25°C, ka ārai i te pakaru o te mea whakapūpū.
3. Uara pH: Te Toi o te Taurite Waikawa-Kawakore
Ko te uara pH, pērā i te waikawa, te kawakore rānei i runga i te papatae, ka pā tika ki te "tuakiri" o ngā mea whakapūkara. I kitea e tētahi wheketere tukatuka kai, e rongoā ana i ngā wai para hinu, i te wā i waenga i te 6 me te 7 te pH, ka taea e ngā ngota wai whakapūkara te kukume i ngā matūriki hinu pērā i ngā aukume. Heoi, i te wā i neke atu ai te pH i te 8, ka wetekina, ka pakarukaru hoki ngā wai whakapūkara, ā, ka heke te tere tango COD mā te 40%. Mā te tāuta i tētahi aroturuki pH ipurangi, i tutuki i ngā tohunga hangarau te whakahaere wā-tūturu, me te whakau i te COD para i raro i te 50 mg/L.
4. Te Whakaohooho: Tukua ngā Ngota kia Kanikani i te Waltz Tino Pai
He rite te tere me te wā o te whakaoho ki te manawataki o te kanikani: ki te tere rawa ka pakaru ngā para, ki te puhoi rawa kāore e tino whakaranua. I whakamahia e te tipu maimoatanga wai para ā-tāone tētahi rautaki whakaoho "tere, kātahi ka puhoi": ko ngā meneti tuatahi e rua i pau ki te whakaoho tere i te 150 rpm kia tino pā te para tango tae me ngā poke; ko ngā meneti e rima i muri mai i pau ki te whakaoho āta i te 30 rpm kia taea ai e ngā para te tipu haere. Nā tēnei huinga o te whakaoho tere me te puhoi i whakanui ake i te rahi o te matūriki para mai i te 50 μm ki te 200 μm, ā, i piki ake te tere o te taunga mā te 3 ngā wā.
5. Wā: Te Toi o te Whakatakotoranga
He rite te wā taunga ki te tukanga hanga waina: he poto rawa, ā, he ngoikore te waina, he roa rawa, ā, ka ngaro tōna hou. I kitea e tētahi pāka ahumahi matū mā roto i ngā whakamātautau whakatairite, i te whakaroahia o te wā taunga mai i te 30 meneti ki te 45 meneti, ka piki ake te tere tango SS mai i te 85% ki te 92%. Heoi, i muri i te 60 meneti, ka whakatārewatia anō ngā para kua taunga nā te "noho roa rawa," ka hoki anō te paru o te para.
Mai i te inenga me te pāmahana ki te uara pH me te whakaoho, ko ia taipitopito o te flocculant tango tae e whakatau ana i te kounga whakamutunga o te wai. E ai ki tētahi miihini maimoatanga wai mātau, "Kāore mātou e tukatuka ana i te wai, engari e kōrero ana ki ngā ngota." Ina kitea ia pata o te rongoā i tōna wāhi tika, ka tika ia nekehanga pāmahana, ā, ka mahia ia meneti o te whakatōtō me te manawanui, ka whakaatu te wai mārama i tēnei whakaute ki te taiao.
