Liquid sodium acetate
1. Manyan alamomi:
Abun ciki: ≥20%, ≥25%, ≥30%
Bayyanar: ruwa mai tsabta kuma mai tsabta, babu wari mai ban haushi.
Ruwa marar narkewa: ≤0.006%
2. Babban manufar:
Don kula da najasar birni, yi nazarin tasirin shekarun sludge (SRT) da tushen carbon na waje (sodium acetate solution) akan denitrification na tsarin da kawar da phosphorus. Sodium acetate ana amfani da shi azaman ƙarin tushen carbon don ɗaukar sludge denitrification, sannan amfani da maganin buffer don sarrafa haɓakar pH yayin aikin denitrification tsakanin kewayon 0.5. Ƙunƙarar ƙwayoyin cuta na iya ɗaukar CH3COONa da yawa, don haka lokacin amfani da CH3COONa azaman tushen carbon na waje don denitrification, ƙimar COD mai zubar da ruwa kuma za'a iya kiyaye shi a ƙaramin matakin. A halin yanzu, maganin najasa a duk birane da gundumomi yana buƙatar ƙara sodium acetate a matsayin tushen carbon don saduwa da ƙa'idodi na matakin farko.
