hoʻoheheʻe sodium formate
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%
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.
