Ka hana a me ka hoʻohana ʻana o ka sodium acetate i ka mālama ʻana i ka wai
ʻO ka hana a me ka hoʻohana ʻana o ka sodium acetate i ka mālama wai ʻino,
Liquid Sodium Acetate, nā hopena sodium acetate wai, nā mea hana wai sodium acetate, ka wai sodium acetate hoʻohana, ʻO nā mea hana sodium acetate,
1. Nā hōʻailona nui:
Maʻiʻo: ≥20%, ≥25%, ≥30%
ʻO ke ʻano: ka wai maʻemaʻe a maopopo, ʻaʻohe ʻala hoʻonāukiuki.
ʻAʻole hiki ke hoʻololi i ka wai: ≤0.006%
2. Ke kumu nui:
No ka mālama ʻana i ka wai ʻino o ke kūlanakauhale, e aʻo i ka mana o ka sludge age (SRT) a me ke kumu kalapona waho (sodium acetate solution) i ka denitrification a me ka wehe ʻana o ka phosphorus. Hoʻohana ʻia ʻo Sodium acetate ma ke ʻano he kumu kalapona hou e hoʻomaʻamaʻa i ka sludge denitrification, a laila hoʻohana i kahi hopena paʻa e kāohi ai i ka piʻi ʻana o ka pH i ka wā o ke kaʻina denitrification i loko o ka laulā o 0.5. Hiki i ka bacteria Denitrifying ke hoʻopili nui i ka CH3COONa, no laila ke hoʻohana nei ʻo CH3COONa i kumu kalapona waho no ka denitrification, hiki ke mālama ʻia ka waiwai COD effluent ma kahi haʻahaʻa. I kēia manawa, pono ka hoʻomaʻamaʻa ʻana i ka wai ma nā kūlanakauhale a me nā kalana e hoʻohui i ka sodium acetate ma ke ʻano he kumu kalapona e hoʻokō i nā kūlana hoʻokuʻu pae mua.

Hoʻokaʻawale ʻia nā huahana sodium sulfate i loko o ka paʻa a me ka wai ʻelua ʻano, paʻa sodium acetate C2H3NaO2 maʻiʻo ≥58-60%, ʻano: colorless a keʻokeʻo aniani aniani. Liquid sodium acetate maʻiʻo: maʻiʻo ≥20%, 25%, 30%. ʻAno: ʻO ka wai maʻemaʻe a maopopo. ʻIke: ʻaʻohe ʻala hoʻonāukiuki, mea hiki ʻole ke hoʻoheheʻe wai: 0.006% a i ʻole.
Noi: Hoʻohana ʻia ka Sodium acetate ma ke ʻano he kumu kalapona hou i nā mea kanu hoʻomaʻemaʻe wai e hoʻomaʻamaʻa i ka sludge denitrification, hiki ke loaʻa i kahi helu denitrification kikoʻī kiʻekiʻe. I kēia manawa, pono ka hoʻohui ʻana o ka sodium acetate ma ke ʻano he kumu kalapona.
1. ʻO ia ka mea nui e hoʻoponopono i ka waiwai PH o ka wai. Hiki iā ia ke hydrolyze i loko o ka wai e hana i nā ion OH-ʻole, hiki ke hoʻokaʻawale i nā ion acidic i ka wai, e like me H+, NH4+ a pēlā aku. ʻO ka hoohalike hydrolysis: CH3COO-+H2O= hoʻohuli =CH3COOH+OH-.
2. Ma ke ʻano he kumu kalapona hou, hoʻohana ʻia ka hopena buffer e kāohi i ka piʻi ʻana o ka waiwai pH i loko o 0.5 i ke kaʻina o ka denitrification. Hiki i nā bacteria Denitrifying ke hoʻopā i ka CH3COONa, no laila hiki ke mālama ʻia ka waiwai COD o ka effluent ma kahi haʻahaʻa ke hoʻohana ʻia ʻo CH3COONa i kumu kalapona hou no ka denitrification. ʻO ka hele ʻana o ka sodium acetate i kēia manawa ke hoʻololi nei i ke kumu kalapona mua, a ʻoi aku ka ikaika o ka wai ma hope o ka hoʻohana ʻana.
3. He kuleana koʻikoʻi ia i ka paʻa o ka maikaʻi o ka wai. I loko o ka wai o ka nitrite a me ka phosphorus, hiki ke hoʻohana ʻia no ka hopena coordination, hiki ke hoʻomaikaʻi i ka ikaika o ka inhibition corrosion. Inā hoʻokō ʻia ka hoʻāʻo ʻana ma nā kumu wai like ʻole, hiki ke hoʻohana mua ʻia kahi mea liʻiliʻi o ka sodium acetate ʻenehana no ka loaʻa ʻana o ke ʻano kūpono. ʻO ka maʻamau, ʻo ke kaʻina hana o ka ʻoihana ʻo ia ka paʻa a me ka wai ratio o 1 a 5, e hoʻopau i ke kaʻina hoʻoheheʻe ma mua o ka hoʻohui ʻana i ka wai no ka dilution.
