ʻO nā hiʻohiʻona a me ka mālama ʻana i ka wai ʻino o ka ʻoihana mahiʻai

ʻO ka wai ʻino mai ka mahiʻai a me ka hana ʻaiHe mau hiʻohiʻona koʻikoʻi e hoʻokaʻawale ai ia mai ka wai ʻino o ke kūlanakauhale maʻamau i mālama ʻia e nā mea kanu hoʻomaʻemaʻe lehulehu a pilikino paha a puni ka honua: he biodegradable a ʻaʻohe mea ʻawaʻawa, akā he kiʻekiʻe ke koi o ka oxygen biological (BOD) a me nā paʻa paʻa (SS). He paʻakikī ke ʻike ʻia ka hoʻohui ʻana o ka wai ʻai a me ka wai ʻai ʻai ma muli o nā ʻokoʻa o ka BOD a me nā pae pH i ka wai ʻōpala mai nā mea kanu, nā huaʻai a me nā huahana ʻiʻo, a me nā ʻano hana ʻai a me nā kau.

Pono ka wai maikaʻi e hana i ka meaʻai mai nā mea maka. ʻO ka holoi ʻana i nā mea kanu e hoʻohua mai ka wai i loaʻa ka nui o nā mea ʻala a me kekahi mea hoʻoheheʻe ʻia. Hiki ke loaʻa nā surfactants a me nā pesticides.
Hoʻopuka pinepine nā hale iʻa (nā mahiʻai iʻa) i ka nui o ka nitrogen a me ka phosphorus, a me nā paʻa paʻa. Hoʻohana kekahi mau hale hana i nā lāʻau lapaʻau a me nā pesticides i loaʻa i ka wai ʻino.

Hoʻopuka nā mea kanu hana waiū i nā mea haumia maʻamau (BOD, SS).
ʻO ka pepehi ʻana a me ka hana ʻana i nā holoholona e hana i nā ʻōpala organik mai nā wai kino, e like me ke koko a me ka ʻōpū. ʻO nā mea haumia i hana ʻia, ʻo ia nō ka BOD, SS, coliform, nā aila, ka nitrogen organik, a me ka amonia.

Hana ʻia ka meaʻai i hana ʻia no ke kūʻai ʻana i ka ʻōpala mai ka kuke ʻana, ka mea i waiwai pinepine i nā mea kanu-organic a loaʻa paha i nā paʻakai, nā mea ʻono, nā mea kala a me nā waikawa a i ʻole nā ​​kumu. Nui paha nā momona, ʻaila a me nā momona ("FOG") i hiki ke hoʻopaʻa i nā ʻauwai. Pono kekahi mau kūlanakauhale i nā hale ʻaina a me nā mea hana meaʻai e hoʻohana i nā mea pale momona a hoʻoponopono i ka lawelawe ʻana o FOG i nā ʻōnaehana sewer.

ʻO nā hana hoʻoponopono meaʻai e like me ka hoʻomaʻemaʻe ʻana i nā mea kanu, ka mālama ʻana i nā mea, ka ʻōmole a me ka hoʻomaʻemaʻe huahana e hana i ka wai ʻino. Nui nā hale hana meaʻai e pono ai ka mālama ʻana ma ka pūnaewele ma mua o ka hoʻohana ʻia ʻana o ka wai ʻino ma ka ʻāina a i ʻole ka hoʻokuʻu ʻia ʻana i loko o kahi ala wai a i ʻole ka ʻōnaehana sewer. Hiki ke hoʻonui i ka BOD i nā pae paʻa paʻa i hoʻokuʻu ʻia a hiki ke hopena i nā uku hoʻonui kiʻekiʻe. Hoʻohana maʻamau ʻia ka hoʻoheheʻe ʻana, nā pale ʻano wedge, a i ʻole ka kānana ʻāwili ʻana (microsieving) e hōʻemi i ka ukana o nā mea paʻa i hoʻokuʻu ʻia ma mua o ka hoʻokuʻu ʻia ʻana. Hoʻohana pinepine ʻia ka Cationic high-efficiency oil-water separator i loko o ka meaʻai meaʻai aila wai hoʻokaʻawale (high-efficiency aila-wai hoʻokaʻawale no ka loaʻa ʻana o nā kinikini anionic a i ʻole nā ​​​​mea i hoʻopiʻi maikaʻi ʻia o ka lepo a i ʻole ka wai ʻino, inā hoʻohana wale ʻia a me ka hoʻohana pū ʻana i ka coagulant inorganic. hiki ke hoʻokaʻawale wikiwiki a hoʻomaʻemaʻe paha i nā kumu wai ka wikiwiki, e hoʻemi i ke kumukūʻai o ka hoʻohana ʻana i nā huahana).
