ʻO ka mea hana hoʻonā sodium acetate, ka hana sodium acetate a me ka hoʻohana

ʻO ka mea hana hoʻonā sodium acetate, ka hana a me ka hoʻohana ʻana i ka sodium acetate,
Pākē sodium acetate solution, Nā mea hoʻolako sodium acetate Kina, Sodium Acetate, hopena sodium acetate, nā hopena a me ka hoʻohana ʻana o ka sodium acetate, ʻO nā mea hana sodium acetate, ʻO ka Sodium Acetate Solution, nā mea hana hoʻonā sodium acetate, nā mea hoʻolako sodium acetate, ka sodium acetate hoʻohana,
ʻO ka sodium acetate wai
① Nā hōʻailona nui:
Maʻiʻo: Maʻiʻo ≥20%, 25%, 30% ʻO ka ʻike: ʻike ʻia ka wai maʻemaʻe a maopopo, ʻike ʻia ka hopena wai o ka huahana a me ka melemele iki.
ʻIke: ʻaʻohe ʻala hoʻonāukiuki. Mea hiki ʻole ke hoʻoheheʻe wai: 0.006% a i ʻole

58% paʻa no ka hoʻomākaukau ʻana i 25% hoʻonā wai:

Wahi a ka ratio o 1 kg o ka sodium acetate i ka 1.3 kg o ka wai, ʻo ka mahana o ka wai ma kahi lumi lumi ma kahi o 20 degere, ʻoi aku ka lohi o ka dissolution rate ma mua o 10 degere.

ʻO ka pae maloʻo o 25% aqueous solution ma kahi o -10 degere.

② Hoʻohana nui:

ʻO ka hana nui o ka sodium acetate wai i ka hoʻomaʻamaʻa ʻana, ʻo ia ke hoʻohui i ke kumu kalapona no ka denitrifying bacteria, hoʻomaʻamaʻa i ka sludge denitrifying, a laila hoʻohana i ka hopena buffer e kāohi i ka piʻi ʻana o ka waiwai pH i ke kaʻina denitrification i loko o ka pae 0.5. 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. I kēia manawa, pono e hoʻohui i ka sodium acetate i ka hoʻomaʻemaʻe ʻana o nā kūlanakauhale a me nā kalana i ke kumu kalapona inā makemake ʻo ia e hoʻokō i ka pae hoʻokuʻu I standard.

③ Ke kūlana hoʻouna:
I ka manawa o 15mg / L ka nui o ka sodium acetate, hiki ke hoʻokō i ka manaʻo puka o kēlā me kēia ʻāpana o ka ʻōnaehana i ka "Discharge Standard of Pollutants from Urban Sewage Treatment Plant" GB18918-2002 Class A standard. I ka 30mg/L, ua kiʻekiʻe ka nui o ka hoʻokuʻu ʻana o ka phosphorus o ka pauku anaerobic, phosphorus absorption rate o ka ʻāpana aerobic a me ka neʻe ʻana o ka pauku anoxic, hiki ke hiki i 3.54 MgPo43-p /(g MLSS·h) 2.54 mgPO43– P/(g MLSS·h). A me 1.53 mgNOx-N/(gMLSS·h). I ka 9mg/L a me ka 15mg/L ka nui o ka sodium acetate, hoʻopau ʻia ka denitrification a me ka wehe ʻana o ka phosphorus ma ka ʻāpana hypoxia, a ʻo ka nui o ka hoʻoheheʻe ʻana o ka phosphorus he 0.36mgPO43-P/(g MLSS·h) a me 0.02(mgPO43-P/( gMLSS·h), ma ka hōʻuluʻulu manaʻo, e ʻoi aku ka paʻa o ka ʻōnaehana i ka 30mg/L.
