Te Wehewehe i ngā Huakita
Whakaahuatanga
Tono kua tukuna
E pā ana ki ngā tipu maimoatanga waipara ā-tāone, ngā waipara o ngā ahumahi matū, te waipara tā me te tae, te waipara o te tāpui whenua, te waipara tukatuka kai me ētahi atu maimoatanga waipara ahumahi.
Pānga Matua
1. He pai te mahi whakapōrearea a ngā huakita wehewehe i ngā mea rauropi i roto i te wai. He tino kaha tōna ātete ki ngā āhuatanga kino o waho, e āhei ai te pūnaha maimoatanga paru kia kaha te ātete ki te ru o te kawenga. I taua wā, he kaha tōna kaha ki te maimoatanga. Ina tino rerekē te kukū o te paru, ka taea hoki e te pūnaha te mahi noa kia pai ai te tukunga o te para.
2. Ka taea e ngā huakita wehewehe te whakangaro i ngā matū macromolecule ātete-wai, ā, ka tangohia ā-kore te BOD, te COD me te TSS. Ka taea e ia te whakanui ake i te kaha o te whakatōtō totoka i roto i te tāke whakatōtō, me te whakanui ake i te rahinga me te kanorau o ngā protozoa.
3. Ka taea e ia te tīmata wawe me te whakaora i te pūnaha wai, ka whakapai ake i tōna kaha tukatuka me tōna kaha ārai-ru.
4. Nō reira, ka taea te whakaiti i te nui o te paru toenga me te whakamahinga o ngā matū pēnei i ngā mea whakapūkara, ā, ka taea hoki te penapena hiko.
Tikanga Tono
1. Me hangai te wai para ahumahi ki te taupū kounga wai o te pūnaha matū koiora, ko te horopeta tuatahi ko te 80-150 g/m3(i tatauhia e te rōrahi o te tāke matū koiora). Mena he nui rawa te piki me te heke o te kaha e pā ana ki te pūnaha, me tāpiri he horopeta o te 30-50 g/m3(ka tatauhia e te rōrahi o te tāke matū koiora).
2. Ko te horopeta o te paru o te tāone he 50-80 g/m3(ka tatauhia e te rōrahi o te tāke matū koiora).
