Palapala Noi i Waiho ʻia
Pili i nā hale hana mālama wai ʻino o ke kūlanakauhale, nā ʻano wai ʻino like ʻole o nā ʻoihana kemika, ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai ʻino, ka leachate landfill, ka wai ʻino hana meaʻai a me nā ʻano hana mālama wai ʻino ʻē aʻe.
Hopena Nui
1. He hana hoʻohaʻahaʻa maikaʻi ko ka bacteria māhele no nā mea olaola i loko o ka wai. Loaʻa iā ia ke kūpaʻa ikaika loa i nā mea ʻino o waho, e hiki ai i ka ʻōnaehana mālama wai ʻino ke kūpaʻa kiʻekiʻe i ka haʻalulu ukana. I kēia manawa, he mana mālama ikaika kona. Ke loli nui ka nui o ka wai ʻino, hiki i ka ʻōnaehana ke hana maʻamau e hōʻoia i ka hoʻokuʻu paʻa ʻana o ka effluent.
2. Hiki i ka bacteria māhele ke luku i nā hui macromolecule refractory, a laila e wehe pololei ʻole ana i ka BOD, COD a me TSS. Hiki iā ia ke hoʻonui nui i ka hiki ke hoʻoheheʻe paʻa i loko o ka pahu sedimentation a hoʻonui i ka nui a me ke ʻano like ʻole o nā protozoa.
3. Hiki iā ia ke hoʻomaka koke a hoʻōla i ka ʻōnaehana wai, e hoʻomaikaʻi ana i kona hiki ke hana a me ka hiki ke kū'ē i ka haʻalulu.
4. No laila, hiki iā ia ke hōʻemi pono i ka nui o ke koena sludge a me ka hoʻohana ʻana i nā kemika e like me nā flocculants a mālama i ka uila.
ʻAno Hoʻopili
1. Pono e hoʻokumu ʻia ka wai hoʻoneoneo ʻoihana ma ka helu kuhikuhi o ka maikaʻi o ka wai o ka ʻōnaehana biochemical, ʻo ka mahele mua he 80-150 g / m3(i helu ʻia e ka nui o ka pahu biochemical). Inā nui loa ka loli o ka influent e hoʻopilikia ana i ka ʻōnaehana, a laila pono ia i kahi mahele hou o 30-50 g/m3(i helu ʻia e ka nui o ka pahu biochemical).
2. ʻO ka nui o ka wai ʻino o ke kūlanakauhale he 50-80 g/m3(i helu ʻia e ka nui o ka pahu biochemical).
