piʻi i luna anaerobic sludge moe reactor (UASB)
ʻO UASB kekahi o nā mea kanu ulu wikiwiki, i hōʻike ʻia e ka kahe o ka wai o ka wai ma lalo o ka moena sludge granular i hoʻonui ʻia. Māhele ʻia ka digester i ʻekolu mau ʻāpana, ʻo ia hoʻi ka moena sludge, layer sludge a me ʻekolu-phase separator. Hoʻokaʻawale ka mea hoʻokaʻawale i ke kinoea a pale i nā mea paʻa mai ka lana ʻana a kahe ʻana i waho, no laila ua hoʻonui nui ʻia ka MRT ke hoʻohālikelike ʻia me HRT, a hoʻomaikaʻi maikaʻi ʻia ka hana metana. ʻO ka wahi moe moe wale nō no 30% o ka nui digester ma ka awelika, akā 80 ~ 90% o nā meaola i hoʻohaʻahaʻa ʻia ma aneʻi.
ʻO ka mea hoʻokaʻawale ʻekolu o ka lakohana kī o ka UASB anaerobic digester. ʻO kāna mau hana nui ka hoʻokaʻawale kino-wai, ka hoʻokaʻawale paʻa-wai a me ka reflux sludge, akā ua haku ʻia lākou āpau i ke sila ʻōpala, ka ʻāpana sedimentation a me ka hui reflux.
Nā pono hana
Has He hale maʻalahi ka digester a ʻaʻohe mea hoʻohuihui a me ka mea hoʻopihapiha (koe ʻekolu mau mea hoʻokaʻawale).
② Hana ʻo SRT lōʻihi a me MRT e hoʻokō i ka helu o ka ukana kiʻekiʻe.
③ ʻO ke kūkulu ʻia ʻana o ka sludge granular e hoʻoneʻe kūlohelohe i ka microorganism a hoʻonui i ka paʻa o ke kaʻina.
④ Haʻahaʻa ka ʻike SS o ka effluent.
Hoʻonohonoho i nā hemahema
. e hoʻouka ʻia ʻekolu mea hoʻokaʻawale.
② koi ʻia kahi mea hāʻawi wai kūpono e hana like i ka hānai.
③ E haʻahaʻa ka ʻike o SS.
④ Ke kiʻekiʻe ka hoʻouka neaa a kiʻekiʻe paha ka ukana SS, maʻalahi e nalo i nā mea paʻa a me nā microorganism.
Requirements Nā koiʻenehana kiʻekiʻe no ka hana.
