Paʻi kānana kāʻei kiʻekiʻe

ʻO ka mīkini kānana kāʻei kiʻekiʻe he ʻano o nā mea hoʻoheheʻe wai me ka hiki ke hana kiʻekiʻe, ka maikaʻi o ka wai hoʻoheheʻe kiʻekiʻe, a me ke ola lawelawe lōʻihi.Ma ke ʻano he mea kākoʻo no ka mālama ʻana i ka wai, hiki iā ia ke kānana a hoʻomaloʻo i nā mea paʻa a me ka sediment ma hope o ka mālama ʻana i ka ea, a kaomi iā lākou i loko o nā pōpō lepo e hoʻokō i ke kumu o ka pale ʻana i ka pollution lua.Hiki ke hoʻohana ʻia ka mīkini no ke kaʻina hana e like me ka slurry concentration a me ka lawe ʻana i ka waiʻona ʻeleʻele.

Kuʻuna Hana

Hiki ke hoʻokaʻawale ʻia ke kaʻina hana hoʻomaʻemaʻe o ke kāʻei kānana kiʻekiʻe i ʻehā mau ʻāpana koʻikoʻi: pre-treatment, gravity dehydration, wedge zone pre pressure dehydration, a kaomi dehydration.I ka wā o ka hoʻomaʻamaʻa mua ʻana, hoʻohui ʻia ka mea flocculated i ke kāʻei kānana, e hoʻokaʻawale i ka wai manuahi ma waho o nā flocs mai nā flocs ma lalo o ka gravity, e hoʻemi mālie i ka ʻike wai o nā flocs sludge a hoʻemi i ko lākou wai.No laila, ʻo ka maikaʻi o ka dehydration o ka ʻāpana dehydration gravity e pili ana i nā waiwai o ke kānana kānana (kāʻei kānana), nā waiwai o ka sludge, a me ke ʻano o ka flocculation o ka sludge.ʻO ka ʻāpana hoʻohaʻahaʻa gravity e wehe i kahi hapa nui o ka wai mai ka ʻōpala.I ka wā o ka wīwī ma mua o ka hoʻoheheʻe ʻia ʻana o ka wai, ma hope o ka hoʻoheheʻe ʻia ʻana o ka gravity dehydration, e emi nui ana kona wai, akā paʻakikī nō naʻe e hoʻokō i nā koi no ka wai o ka sludge i ka pauku dehydration kaomi.No laila, ua hoʻohui ʻia kahi ʻāpana hoʻoheheʻe wai ma mua o ke kaomi ʻana ma waena o ka pauku dehydration kaomi a me ka pauku dehydration gravity o ka sludge.ʻO ka sludge i kahi liʻiliʻi a maloʻo i loko o kēia ʻāpana, e wehe ana i ka wai manuahi ma luna o kona ʻili, a ʻaneʻane nalowale ka wai, ʻo kēia ka mea e hōʻoia ai ʻaʻole e ʻoki ʻia ka sludge i loko o ka pauku dehydration kaomi ma lalo o nā kūlana maʻamau, e hana ana i nā kūlana no ka paʻi paʻa. dehydration.

Ka Lahui Noi

He kūpono ka mīkini kānana kāʻei kiʻekiʻe no ka hoʻomaʻemaʻe ʻana i ka wai i loko o nā ʻoihana e like me ka hoʻoheheʻe ʻana o ke kūlanakauhale, ka paʻi lole a me ke kala, electroplating, papermaking, ʻili, brewing, meaʻai, holoi lanahu, petrochemical, chemical, metallurgical, pharmaceutical, ceramic, etc. He kūpono hoʻi ia no ka hoʻokaʻawale paʻa a i ʻole nā ​​​​kaʻina leaching wai i ka hana ʻoihana.

Nā mea nui

ʻO ka mīkini kānana kāʻei kiʻekiʻe ka nui o kahi mea hoʻokele, kahi kiʻi, kahi pahu paʻi, kahi kāʻei kānana kiʻekiʻe, kahi kāʻei kānana haʻahaʻa, kahi mea hoʻonaninani kāʻei kānana, kahi mea hoʻomaʻemaʻe kāʻei kānana, kahi mea hoʻokuʻu, kahi mana pneumatic. ʻōnaehana, ʻōnaehana hoʻokele uila, etc.

Kaʻina hana hoʻomaka

1. E hoʻomaka i ka ʻōnaehana hui ʻana i ka lāʻau a hoʻomākaukau i kahi solution flocculant ma kahi ʻano kūpono, maʻamau ma 1 ‰ a i ʻole 2 ‰;

2. E hoʻomaka i ka ea compressor, e wehe i ka intake valve, e hoʻololi i ke kaomi intake i 0.4Mpa, a nānā i ka hana maʻamau o ka ea compressor;

3. E wehe i ka pahu komo nui e hoʻomaka i ka hoʻomaʻemaʻe wai a hoʻomaka e hoʻomaʻemaʻe i ke kāʻei kānana;

4. E hoʻomaka i ka mīkini hoʻoili nui, a i kēia manawa, hoʻomaka ke kāʻei kānana e holo.E nānā inā e holo maʻamau ana ke kāʻei kānana a e holo ana paha.E nānā inā he mea maʻamau ka hāʻawi ʻana o ka ea i nā ʻāpana pneumatic, inā paha e hana pono ana ka mea hoʻoponopono, a inā he maʻamau kēlā me kēlā me kēia huila kaʻa kaʻa a ʻaʻohe leo kūlohelohe;

5. E hoʻomaka i ka mea hui flocculation, flocculant dosing pump, a me ka sludge feed pump, a nānā i ka hana no nā walaʻau like ʻole;

6. Hoʻoponopono i ka nui o ka sludge, dosage, a me ka wikiwiki o ka hoʻololi ʻana o ke kāʻei kānana e hoʻokō i ka hiki ke hoʻomaʻamaʻa maikaʻi loa a me ka helu dehydration;

7. E ho'ā i ka peʻahi hoʻopau i loko a hoʻopau i ke kinoea i ka hikiwawe;

8. Ma hope o ka hoʻomaka ʻana i ka paʻi kānana kiʻekiʻe, e nānā inā holo maʻamau ke kāʻei kānana, e holo ana i ka deviation, a me nā mea ʻē aʻe, inā paha e hana pono ana ka mīkini hoʻoponopono, inā he mea maʻamau nā ʻāpana wili a pau, a inā he walaʻau ʻokoʻa.
