Maopopo anei iā ʻoe?Ma waho aʻe o nā ʻōpala e pono e hoʻokaʻawale ʻia, pono e hoʻokaʻawale ʻia ka leachate landfill.
E like me nā hiʻohiʻona o ka hoʻoheheʻe ʻāina, hiki ke hoʻokaʻawale ʻia i: ka hoʻoili ʻana i ke kahua hoʻopaʻa ʻāina leachate, kīhini ʻōpala leachate, landfill landfill leachate, a me nā mea kanu hoʻoheheʻe ʻia.
He aha nā hiʻohiʻona o kēia mau ʻano ʻehā o ka ʻōpala ʻāina?
ʻO nā hiʻohiʻona o ka leachate station transfer:
1. Nui nā kumu nui o ka wai ʻino: ʻo ka wai ʻino ka nui o ka hale, ka wai ʻōpala, a me ka leachate landfill.
2. Ma muli o ka pōkole o ka noho ʻana o ka ʻōpala i loko o ke keʻena hoʻoili ʻōpala, liʻiliʻi ka puka o ka leachate.
3.ʻOi aku ka haʻahaʻa o ka pollutants ma ke kahua hoʻoili ma mua o nā mea haumia ʻē aʻe, a ʻo ka neʻe ʻana o COD ma kahi o 5000 ~ 30000mg / L..
ʻO nā hiʻohiʻona nui o ka leachate landfill:
①Nui nā ʻano mea hoʻohaumia kūlohelohe, a paʻakikī ka maikaʻi o ka wai (loaʻa nā ʻano mea ʻona)
②ʻO ke kiʻekiʻe o ka pollutants a me ka laulā o nā loli (ʻo ka BOD mua a me ka COD ka mea kiʻekiʻe loa, a hiki i nā ʻumi kaukani milligrams i ka lita, pH waiwai ma kahi a haʻahaʻa iki paha ma mua o 7, B / C ma waena o 0.5-0.6, a me ka maikaʻi nā waiwai biochemical), ma ka ʻōlelo maʻamau, e emi ana ka ratio COD, BOD, BOD/COD me ka "makahiki" o ka pae ʻāina, a piʻi ka alkalinity.
③ʻOkoʻa loa ka maikaʻi a me ka nui o ka wai: ʻokoʻa ka nui o ka wai me nā kau (ua ʻoi aku ka nui o ka ua ma mua o ke kau maloʻo);ke hoʻololi pū nei ka haku mele ʻana a me ka noʻonoʻo ʻana o nā mea haumia me nā kau;ke hoʻololi ʻia ka haku mele ʻana a me ka neʻe ʻana o nā mea haumia me ka manawa o ka pae ʻāina.
ʻO nā hiʻohiʻona nui o ka leachate landfill i nā mea kanu incineration:
①Nā kiʻekiʻe kiʻekiʻe o COD, BOD, a me ka amonia nitrogen (hiki i ka COD ke hiki i 40,000 ~ 80,000)
②ʻOi aku ka lōʻihi o ka manawa fermentation ma mua o ka hale hoʻoili.
ʻO nā hiʻohiʻona nui o ka leachate ʻōpala kīhini:
①ʻO nā mea paʻa kiʻekiʻe i hoʻokuʻu ʻia: ʻO nā leachates ʻokoʻa nā ʻāpana like ʻole o nā mea paʻa i hoʻopaʻa ʻia i ke kūlana hoʻonā a me ka colloidal state, e like me ke kiʻekiʻe o 60,000 a 120,000 mg/L, me ka hoʻopuehu kiʻekiʻe a paʻakikī ke hoʻokaʻawale;
②ʻO ka aila kiʻekiʻe: ka nui o nā aila holoholona a me nā mea kanu, a hiki i 3000mg/L ma hope o ka hoʻomaʻamaʻa ʻana
③COD kiʻekiʻe, maʻalahi maʻalahi e biodegrade, a hiki i 40,000 a 150,000 mg / L;
④pH haʻahaʻa (maʻamau ma kahi o 3);⑤nui ka paʻakai.
