Paʻi kānana kāʻei lepo

Paʻi kānana kāʻeihe 'ano o ka sludge dewatering lako me ke ki'eki'e ka hana 'ana, ki'eki'e dewatering pono, a me ka lō'ihi o ka lawelawe 'ana.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 dehydration o ka paʻi kānana kāʻei i ʻehā mau pae koʻikoʻi: pre-treatment, gravity dehydration, wedge zone pre pressure dehydration, and press 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.
