Loaʻa ka hoʻouna ʻana i ka lele lele ʻana

I Kekemapa, 2021, ua hoʻopau ʻia ka lele ʻana o ka ea i hoʻoheheʻe ʻia a hoʻokō i ke kūlana o ka hale hana e hoʻopuka maikaʻi ai.

ʻO ka Dissolved Air Flotation (DAF System) kahi hana mālama wai e hoʻomaʻamaʻa ana i ka wai ʻino (a i ʻole wai ʻē aʻe, e like me ka muliwai a i ʻole ka loko) ma ka wehe ʻana i nā mea paʻa susupended a i ʻole ka aila a me ka momona.Hoʻohana nui ʻia ia i ka mālama wai ʻino no ka hoʻokaʻawale ʻana i ka wai paʻa, hiki iā ia ke wehe i nā mea paʻa i hoʻokuʻu ʻia, ka aila a me ka momona a me ka waiwai colloidal.I kēia manawa, hiki ke hoʻemi ʻia ka COD, BOD.ʻO ia ka mea hana nui no ka mālama ʻana i ka wai ʻōpala.

Nā hiʻohiʻona hoʻolālā
ʻO ka ʻōnaehana DAF ka nui o ka pauma ea i hoʻoheheʻe ʻia, ka ea compressor, ka moku ea i hoʻoheheʻe ʻia, ke kino pahu kila rectangle, ka ʻōnaehana skimmer.

1. ʻO ka hana maʻalahi a me ka hoʻokele maʻalahi, ka mālama pono ʻana i ka nui a me ka maikaʻi o ka wai.

2. ʻO nā micro bubbles i hana ʻia e ka moku ea i hoʻoheheʻe ʻia he 15-30um wale nō, ʻo ia ka mea hoʻopili me ka flocculant ikaika e hoʻokō i ka hopena flotation maikaʻi.
3. Unique GFA dissolved ea nenoaiu, kiʻekiʻe ka pono o ka ea dissolving hiki i 90% +, ikaika ikaika no ka clogging.

4. Chain-plate type skimmer, paʻa ka hana a me ka hana kiʻekiʻe e ʻoki.

Manao Hana

ʻO ka wai ea i hoʻoheheʻe ʻia e ka ʻōnaehana GFA e puhi ʻia i loko o ka mea hoʻokuʻu ea ma ka hoʻemi ʻana i ke kaomi.ʻO 15-30um mau ʻōhū liʻiliʻi mai ka mea hoʻokuʻu ea e hoʻopili i nā mea paʻa i hoʻopaʻa ʻia e ʻoi aku ka māmā ma mua o ka wai, a laila hiki ke lana nā mea paʻa i hui pū ʻia me nā ʻōpala liʻiliʻi ma luna o ka ʻili e hana i kahi papa scum e ʻoki ʻia e ka ʻōnaehana skimmer i loko o ka pahu sludge. .Kahe ka wai maʻemaʻe haʻahaʻa i loko o ka pahu wai maʻemaʻe.ʻO ka liʻiliʻi he 30% o ka wai maʻemaʻe e hana hou ʻia no ka ʻōnaehana GFA aʻo nā mea ʻē aʻe e hoʻokuʻu ʻia a paʻi ʻia i ke kaʻina hana aʻe.

Palapala noi

ʻO ka ʻōnaehana DAF, ma ke ʻano he kaʻina hoʻomaʻemaʻe wai hoʻokahi, hoʻohana nui ʻia i ka ʻenekini hoʻomaʻemaʻe wai.Hiki ke hoʻohana ʻia no kēia mau ʻoihana:

1. ʻOihana pepa - hana hou ka pulp i ka wai keʻokeʻo a me ka wai maʻemaʻe i hana hou ʻia no ka hoʻohana ʻana.

2. ʻOihana lole, paʻi a me ka hoʻoluʻu - hoʻemi ʻana i ka chromaticity kala a me ka wehe ʻana o SS

3. Hale pepehi kanaka a me ka 'oihana mea'ai

4. ʻOihana Petro-chemical - hoʻokaʻawale ʻaila-wai
