ʻO nā lako hoʻomaʻemaʻe wai wai

Nā kumu o ka wai hoʻoheheʻe wai

Kaʻina hana: hoʻoheheʻe ʻia nā mea maka → iʻa ʻoki ʻia → hoʻomaʻemaʻe → ka hoʻouka ʻana i ka pā → hoʻoheheʻe wikiwiki ʻO nā mea iʻa maloʻo ka hoʻoheheʻe ʻia ʻana o ka iʻa, ka holoi ʻana i ka wai, ka mālama ʻana i ka wai, disinfection, hoʻomaʻemaʻe a me nā kaʻina hana ʻē aʻe e hoʻopuka i ka wai ʻino, nā mea haumia nui i hoʻokuʻu ʻia mai ka wai holoi o nā lako hana. a me ka papa hana he CODcr, BOD5, SS, amonia nitrogen, etc.

ʻenehana kaʻina hana mua

Ma muli o ka hoʻokuʻu ʻole ʻia ʻana o ka wai hoʻoheheʻe wai a me nā loli nui o ka maikaʻi o ka wai, pono ia e hoʻoikaika i nā hana ma mua o ka mālama ʻana i mea e loaʻa ai nā hopena lapaʻau paʻa.Hoʻopaʻa ʻia ka wai ʻōpala e kahi mānoanoa e wehe i nā mea ʻala mai ka wai, a ua hoʻokaʻawale ʻia nā mea paʻa paʻa e like me ka ʻili iʻa, ka ʻili ʻiʻo, a me nā iwi iʻa ma mua o ke komo ʻana i ka pahu hoʻoponopono.Hoʻokomo ʻia kahi mea aeration i loko o ka pahu, nona nā hana e like me ka deodorization a me ka wikiwiki i ka hoʻokaʻawale ʻana o ka aila i loko o ka wai ʻino, hoʻomaikaʻi i ka biodegradability o ka wai ʻino a me ka hōʻoia ʻana i ka maikaʻi o ka mālama olaola ma hope.Ma muli o ka nui o ka momona i loko o ka wai ʻino, pono e hoʻokomo ʻia nā mea lawe ʻaila.No laila, ʻo ke kaʻina hana ma mua o ka: grating and lifting pump room, air flotation tank, hydrolysis acidification tank.

Ke koi hana

1. ʻO ka maikaʻi o ka effluent o ka hoʻokuʻu ʻana i ka wai hoʻoheheʻe e kū i ke kūlana pae mua i ʻōlelo ʻia ma ka "Comprehensive Wastewater Discharge Standard" (GB8978-1996).

2. Pono ʻenehana:

① Pono ke kaʻina hana * *, ʻenehana hilinaʻi, a me ka hoʻokele waiwai.Pono ka hoʻolālā kūpono a me ka wāwae liʻiliʻi.

② ʻO nā keʻena nui o ka hale hoʻoheheʻe wai e hoʻohana i kahi ʻano kila kila semi aboveground.

③ Hoʻopili ʻia ka wai inlet ma o ka paipu pipili, me ke kiʻekiʻe o lalo o -2.0m.Ma hope o ka hele ʻana i ka pūnāwai ana, hoʻoheheʻe ʻia ka wai i loko o ka paipu aupuni ma waho o ka hale hana.

ʻO ka maʻamau pae mua i kuhikuhi ʻia ma ka “Comprehensive Wastewater Discharge Standard” (GB8978-1996): wae: mg/L paʻa paʻa SS ＜ 70;BOD < 20;COD<100;Ammonia nitrogen<15.
