ʻIke a me ka hoʻohana ʻana i ka mālama ʻana i ka wai

I.He aha ka wai ʻino?

ʻO ka wai hoʻoheheʻe e pili ana i ka wai i hoʻokuʻu ʻia mai ka hana a me nā hana ola. Hoʻohana nui nā kānaka i ka wai i ke ola o kēlā me kēia lā a me nā hana hana, a lilo kēia wai i mea haumia i nā pae like ʻole. Kapa ʻia ka wai i hoʻohaumia ʻia.

II.Pehea e hana ai i ka lepo?

Hoʻohana ʻia ka mālama ʻana i ka wai i nā ʻenehana a me nā ʻano hana like ʻole e hoʻokaʻawale, wehe, a hana hou i nā mea haumia i loko o ka ʻōpala a i ʻole e hoʻololi iā lākou i mea ʻino ʻole, no laila e hoʻomaʻemaʻe i ka wai.

III.Application o biochemical lapaʻau i loko o ka lepo?

Hoʻohana ka lāʻau biochemical o ka ʻōpala i nā kaʻina ola microbial e hoʻopau pono i nā mea hoʻoheheʻe ʻia a me kekahi mau mea ola ʻole mai ka wai ʻino, e hoʻomaʻemaʻe i ka wai.

IV. Ka wehewehe ʻana o ka maʻi bacteria aerobic a me anaerobic?

Aerobic bacteria: ʻO nā bacteria e koi ana i ka loaʻa ʻana o ka oxygen manuahi a ʻaʻole i hoʻopau ʻia ma ke alo o ka oxygen manuahi. ʻAnaerobic bacteria: ʻAʻole pono nā bacteria i ka oxygen manuahi a ʻaʻole hoʻopau ʻia me ka loaʻa ʻole o ka oxygen manuahi.

V.Relationship ma waena o ka wai wela a me ka hana?

Hoʻopilikia nui ka mahana o ka wai i ka hana o nā pahu aeration. I loko o kahi hale hoʻoheheʻe wai, hoʻololi mālie ka mahana o ka wai me nā kau a hiki ʻole ke loli i loko o hoʻokahi lā. Inā ʻike ʻia nā loli koʻikoʻi i loko o hoʻokahi lā, pono ke nānā ʻia e nānā i ke komo ʻana o ka wai hoʻoluʻu ʻoihana. Aia ka mahana o ka wai makahiki ma waena o 8-30 ℃, e emi ana ka maikaʻi o ka mālama ʻana o ka pahu aeration i ka wā e hana ana ma lalo o 8 ℃, a ʻo ka helu hoʻoneʻe BOD5 ma lalo o 80%.
