Pili pili ke ola o kēia au me nā hana o ka ʻoihana kemika. 'Pala, nā mea hoʻonaninani, nā ʻōpala hana - pono kēia i ka hoʻolei kūpono. ʻO "ʻōpala" i loaʻa ʻia e nā kemika ke ʻano o ka wā palaho lōʻihi, a i kekahi mau hihia, kahi weliweli nui i ke kaiapuni.
He aha ka mea i kapa ʻia he ʻōpala kemika?
ʻO ka ʻōpala kemika kahi "ʻōpala" like ʻole i hoʻokumu ʻia e nā hana o ka ʻoihana pili. ʻŌpala i nā kaha puana, e like me ka hoʻohui i nā mea paʻa, aia paha he wai. ʻO ka mea mua, he ʻōpala kēia mai nā ʻoihana kemika e hana i nā mea reagents a me nā hoʻomākaukau no ka hoʻohana hou.
ʻO ka hana ʻana i nā mea ukana, nā lāʻau, ka wahie no ka lawe ʻana, nā mea kanu mahiʻai a me nā waiwai ʻē aʻe e pili pū ana i ka hana ʻana i nā ʻōpala like ʻole e hiki ke hōʻeha i ke kaiapuni a me nā kānaka.
He aha ke ʻano o nā ʻōpala kemika ma laila?
Māhele ʻia kahi ʻōpala o kahi ʻano kemika i hiki ke hoʻolei ʻia i mau ʻano: acid, alkalis, pesticides, residues aila, electrolytes, nā aila a me nā lāʻau lapaʻau. Hoʻokumu ʻia ka aila ʻōpala i ke kaʻina hana o ka loaʻa ʻana o ka ʻaukā, ka wahie diesel, ka ʻaila, ka aila wahie a ʻaʻole hiki ke hoʻohana hou ʻia. Hoʻomaʻamaʻa hou ʻia nā wai a me nā alkali, akā pono lākou e hoʻolei ʻia i nā nui i nā landfill kūikawā.
I kekahi mau mea, hiki ke koho ʻia nā mea hale i hopena o ka hana o ka hana kemika ma ke ʻano he neoneo kemikala. ʻO ka mea mua loa, ʻo kēia nā ʻano āpau āpau. ʻO nā manawa i piha ka meaʻai a me nā pono hana hale i loko o ka pepa ua hala lōʻihi a i kēia manawa ke noho aliʻi nei nā wahī ma aneʻi. ʻO nā ʻeke, nā ʻeke kūʻai, nā kāleka plastic, nā mea pono kīnā ʻole - hoʻolei ʻia kēia mau mea āpau i nā landfills maʻamau, akā he wā lohi loa. Inā ʻaʻohe mea i koe o ka pahu pepa i hoʻokahi makahiki a i ʻole ʻelua, a laila e waiho ka ipu ʻeleʻele ma ka landfill i 30 mau makahiki. ʻO ka hapa nui o nā mea lula ʻaʻole e hoʻopau loa a hiki i ka makahiki 50th.
He aha ka hopena i nā ʻōpala kemika?
Hiki ke hoʻolilo i nā ʻōpala kemika i mau mea maka no kekahi hana hana ʻē aʻe, a i ʻole hoʻolilo ʻia. Kaukaʻi ʻia i ke ʻano o ka ʻōpala a me ke kēkelē o kona makaʻu i ka honua puni, aia nā ʻenehana hoʻolei ʻokoʻa: ka hoʻohaʻahaʻa, chlorination me ka hoʻowali ʻana, ka waiʻona, ke ʻano thermal, distillation, ke ʻano biological. Hoʻonohonoho ʻia kēia mau hana āpau e hōʻemi i ka mea ʻawahia o kahi kemika, a i kekahi mau manawa e loaʻa nā waiwai ʻē aʻe e pono ai no ka mālama ʻana i loko.
ʻO ka hapanui o nā ʻōpala kemika he mea weliweli a weliweli loa ia. No laila, hoʻokokoke ʻia kā lākou hoʻolilo kuleana. Hoʻokomo pinepine ʻia nā ʻoihana loea no kēia kumu. No kekahi ʻano ʻōpala, no ka laʻana, nā huahana koena o ka distillation aila, hana ʻia nā landfills kūikawā - kahi waiho sludge.
ʻO ka hana hou ʻana i nā ʻōpala kemika e hoʻopili pinepine i ka hana hou ʻana. Eia kekahi, i nā manawa he nui, hiki ke hana hou ʻia nā ʻōpala o ka home, kahi mea weliweli i ke kaiapuni ma mua o ke kau ʻana i kahi landfill. No kēia kumu, ua haku ʻia ka hōʻiliʻili ʻōpala a me ka hoʻokaʻawale ʻana i nā mea kanu.
ʻO kahi laʻana maikaʻi o ka hana hou ʻana i nā ʻōpala kemika o ka home ka shredding o nā lula a me ka hana ʻana i kahi nuipa no ka hoʻolei hou. Hiki ke hoʻohana kūleʻa ʻia nā pika kaʻa maʻamau no ka hana ʻana o ka palupalu, kahi ʻāpana o nā uhi o nā kahua pāʻani, anoaeuoiau, ka papa hele ma nā pae pae.
Nā kemika weliweli i ke ola o kēlā me kēia lā
Hana ʻia i ke ola o kēlā me kēia lā ke alo nei kekahi kanaka i kahi kemikina e hoʻoneʻe i kahi weliweli koʻikoʻi. ʻO kahi laʻana, inā ʻoe e uhaʻi i kahi thermometer lapaʻau maʻamau, a laila e ninini ʻia ka mercury. Hiki ke hoʻoheheʻe kēia metala i ke ana wela o ka lumi, a ʻawahia kāna mau mahu. Hiki i ka lawelawe lima ʻole ʻana o ka mercury ke alakaʻi i ka lāʻau make, no laila, ʻoi aku ka maikaʻi o ka hāʻawi ʻana i kēia mea i ka poʻe loea a kāhea i ke Kuhina o nā Pilikia.
Hiki i kēlā me kēia ke hana i kahi kōkua maʻalahi akā maikaʻi loa i ka hoʻolei ʻana i nā ʻōpala o ka home i makemake ʻole ʻia no ke kaiapuni. ʻO kahi laʻana, hoʻolei ʻōpala i nā ipu kaʻawale, a hāʻawi i nā paila (loaʻa iā lākou ka electrolyte) i nā helu hōʻiliʻili loea. Eia naʻe, ʻo ka pilikia ma kēia ala ʻaʻole wale ka nele o ka makemake e "hoʻopilikia", akā ʻo ka nele pū kekahi o nā hanana. I ka hapa nui o nā kauhale liʻiliʻi ma Rūsia, ʻaʻohe wahi ohi no nā pākahiko a me nā ipu ʻōpala kaʻawale.
