Hiki ke lilo ka ʻōpala i mea nui

ʻO ka hoʻopau ʻana i ka ʻōpala, i ka manaʻo o nā poʻe he nui, me he mea lā e hoʻopuka i ka haumia lua, a ʻo ka dioxin i hana ʻia i loko o ia mea e kamaʻilio ai nā kānaka.Eia nō naʻe, no nā ʻāina hoʻopau ʻōpala holomua e like me Kelemānia a me Iapana, ʻo ka incineration ka mea koʻikoʻi, ʻo ka loulou nui, o ka hoʻolei ʻōpala.I kēia mau ʻāina, ʻaʻole i hōʻole ʻia nā mea kanu ʻōpala nui e ka poʻe.No ke aha kēia?

E hana ikaika i ka mālama pono ʻole
Ua kipa aku nei ka mea kākau moʻolelo i ka hale hoʻoheheʻe ʻo Taisho ma lalo o ka Environmental Bureau o Osaka City ma Iapana.Ma ʻaneʻi ʻaʻole e hōʻemi nui i ka nui o ka ʻōpala ma ka hoʻopau ʻana i nā mea puhi ahi, akā hoʻohana maikaʻi nō hoʻi i ka wela ʻōpala e hana i ka uila a hāʻawi i ka ikehu wela, hiki ke ʻōlelo ʻia e lawelawe i nā kumu he nui.

ʻO nā mea e pono ai no ka hoʻopau ʻana i nā ʻōpala e pāʻani i nā hana he nui i ka hoʻokahi hahau ʻana he palekana a me ka haumia haʻahaʻa.Ua ʻike ka mea kākau moʻolelo i loko o ka hale hana o ka Dazheng Waste Treatment Plant he 40 mika ka hohonu o ka nui Waste shaft a he 8,000 cubic mika ka nui, hiki ke paʻa ma kahi o 2,400 tons o Waste.Na ke kookoo e hoomalu mamao i ka crane ma hope o ka paia pale aniani ma ka piko, a hiki ke hopu i 3 tona o na opala i ka manawa hookahi a hoouna aku i ka insinerator.

ʻOiai ka nui o ka ʻōpala, ʻaʻohe ʻala hoʻopailua i loko o ka hale hana.ʻO kēia no ka mea, ʻo ka ʻala i hana ʻia e ka ʻōpala e unuhi ʻia e ka peʻahi hoʻopau, hoʻomehana ʻia i 150 a 200 degere Celsius e ka ea preheater, a laila hoʻouna ʻia i ka incinerator.Ma muli o ke kiʻekiʻe o ka wela o ka umu, ua pau nā mea ʻala.

I mea e pale aku ai i ka hana ʻana o nā carcinogen dioxins i ka wā e hoʻopau ʻia ai, hoʻohana ka mea puhi ahi i kahi wela kiʻekiʻe o 850 a 950 degere Celsius e puhi loa i ka ʻōpala.Ma o ka pale nānā, hiki i nā limahana ke nānā i ke kūlana i loko o ka incinerator i ka manawa maoli.

Hoʻopili ʻia ka lepo i hana ʻia i ka wā o ka hoʻopau ʻana i ka ʻōpala e ka mea ʻohi lepo uila, a ua hana pū ʻia ke kinoea hoʻopau ʻia e nā mea holoi holoi, kānana ʻili lepo, a me nā mea ʻē aʻe, a hoʻokuʻu ʻia mai ke kapuahi ma hope o ka hālāwai ʻana i nā kūlana palekana.

ʻO ka lehu hope loa i hana ʻia ma hope o ka hoʻopau ʻia ʻana o ka ʻōpala ma kahi o hoʻokahi hapa iwakālua wale nō o ka leo kumu, a ʻo kekahi mau mea ʻino ʻaʻole hiki ke pale loa ʻia ua mālama pono ʻia me nā lāʻau lapaʻau.Ua lawe ʻia ka lehu i Osaka Bay no ka hoʻopaʻa ʻana.

ʻOiaʻiʻo, ʻo nā mea kanu hoʻōla ʻōpala e kālele ana i ka incineration he ʻoihana hoʻohui waiwai, ʻo ia hoʻi ka unuhi ʻana i nā kumuwaiwai pono no nā ʻōpala nui ʻole hiki ke puhi ʻia e like me nā keʻena hao, nā moena, a me nā kaʻa.Aia kekahi mau mea hoʻoheheʻe nui i loko o ka hale hana.Ma hope o ka ʻoki ʻia ʻana o nā mea i ʻōlelo ʻia ma luna, koho ʻia ka ʻāpana metala e kahi mea hoʻokaʻawale magnetic a kūʻai ʻia ma ke ʻano he kumu waiwai;ʻoiai e wehe ʻia ka pepa a me nā ʻōpala i hoʻopili ʻia i ka metala e ka nānā ʻana i ka makani, a hoʻouna pū ʻia nā ʻāpana ʻē aʻe i ke ahi.

Hoʻohana ʻia ka wela i hana ʻia e ka ʻōpala ʻōpala no ka hana ʻana i ka mahu, a laila hoʻoheheʻe ʻia i nā turbine mahu no ka hana mana.Hiki i ka wela ke hāʻawi i ka wai wela a me ka wela no nā hale hana i ka manawa like.Ma 2011, ma kahi o 133,400 tons o ka ʻōpala i puhi ʻia ma ʻaneʻi, ua hiki i ka hana mana i 19.1 miliona kwh, ʻo ke kūʻai uila he 2.86 miliona kwh, a ua hiki ke loaʻa i ka 23.4 miliona yen.

Wahi a nā hōʻike, ma Osaka wale nō, aia nō he 7 mau mea kanu ʻōpala e like me Taisho.Ma Iapana holoʻokoʻa, he mea nui ka hana maikaʻi ʻana o nā mea kanu ʻōpala o ke kūlanakauhale e pale aku i nā pilikia e like me ka "Waste siege" a me ka "pollution landfill of water source".
