ʻO nā lako hoʻomaʻamaʻa wai ʻōpala i loko o ka pahu pehea e hana ai i ka wai ʻōpala kiʻekiʻe o ka ʻoihana

Me ka hoʻomau mau ʻana o ka hoʻomohala ʻana i ka ʻoihana ma Kina, ke hoʻomāhuahua nei nā ʻano wai ʻona a pau. E hoʻohaumia i nā kino wai i ka wai ʻino nui i hana ʻia e ka ʻoihana, i hiki ʻole i nā mea ola i loko o nā kino wai ke ola, e luku ana i ke koena kaiaola; inā komo ka wai ʻino i loko o ka lepo, e hoʻohaumia nō hoʻi ia i ka wai lepo, e pili ana i ka palekana o ka wai inu o kānaka. Eia kekahi, hiki ke hoʻolilo ʻia kekahi mau mea ʻawaʻawa a me nā mea ʻino i ka wai ʻino i loko o ke kaulahao meaʻai a komo i loko o ke kino o ke kanaka, e hoʻoweliweli ana i ke olakino kanaka, e koi ana i ka hoʻomaʻamaʻa ʻoihana me nā mea hoʻomaʻamaʻa wai hoʻoneʻe kiʻekiʻe.

I kēia manawa, ʻo ka wai ʻōpala kiʻekiʻe e hiki ai iā mākou ke hoʻopili i ka: ʻoihana kemika wai ʻino, lāʻau lapaʻau wai ʻino, paʻi a me ka wai kala ʻana, electroplating wastewater a pēlā aku. Loaʻa paha i kēia mau wai ʻino ka nui o nā mea olaola, nā mea ʻole, nā metala kaumaha, nā mea ʻona a me nā mea pōʻino.

He nui nā pilikia i ka mālama ʻana i ka wai ʻino nui, ʻo ia hoʻi: mua, . ʻO ke kiʻekiʻe kiʻekiʻe: ʻo ke kiʻekiʻe o nā mea haumia i loko o ka wai ʻino e pono ai nā ala lapaʻau ikaika loa no ka wehe pono ʻana. ʻO ka lua, ka haku mele paʻakikī: ʻo ka wai ʻōpala kiʻekiʻe ka mea maʻamau i loaʻa nā ʻano mea haumia, a paʻakikī kona haku ʻana, e paʻakikī ke mālama ʻia. ʻO ke kolu, maikaʻi ʻole ka biodegradability: ʻaʻole hiki ke hoʻoheheʻe ʻia kekahi o ka wai ʻino nui loa, a pono e hana mua ʻia me nā ʻano lapaʻau ʻē aʻe. ʻEhā, ʻona nui: aia paha kekahi mau mea ʻawaʻawa i loko o kekahi wai ʻona nui, e hoʻoweliweli ana i nā mea hana lapaʻau a me nā mea hana. ʻO ka lima, ʻo ka paʻakikī o ka loaʻa ʻana: kiʻekiʻe ka nui o ka wai ʻino i ke kaʻina hana, e hoʻokō i ka paʻakikī o ka loaʻa ʻana a me ka hoʻohana hou ʻana.

I kēia manawa, makemake nā mea hana hoʻomaʻemaʻe wai hoʻomaʻamaʻa kiʻekiʻe e hana i kēia ʻano wai, hoʻohana nui i ke ʻano o ka mālama kino, ke ʻano hana kemika, ke ʻano o ka mālama ola, ke ʻano hoʻokaʻawale membrane, ke ʻano o ka oxidation kiʻekiʻe, a me nā mea ʻē aʻe, ka mālama maoli, pinepine e like me ka nā hiʻohiʻona o ka wai ʻino a me nā koi lapaʻau, koho i ke ʻano lapaʻau kūpono a i ʻole ka hui pū ʻana o nā ʻano hana like ʻole.

Liding kaiapuni mālama 'oihana i hana i ka hoʻomaʻemaʻe wai no ka oi aku mamua o umi makahiki manawa, kona hana ana a me ka noiʻi a me ka hooulu ana o kiʻekiʻe-concentration wai wastewater lāʻau 'o Blue Whale moʻo, i kela la i keia la hiki ke hoʻoponopono i oi aku mamua o hoʻokahi haneri tonnes o kiʻekiʻe-concentred wai wastewater, ikaika a paʻa. kūpono ke kumu kūʻai, kūpono ka effluent i nā kūlana.
