Bayyanar: ruwa mai tsabta kuma mai tsabta, babu wari mai ban haushi.
Ruwa marar narkewa: ≤0.006%

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.

Aikace-aikacen sodium acetate a matsayin ƙarin tushen carbon don tsire-tsire masu kula da ruwa ya haɗa da matakai masu zuwa

1) Daidaita ƙimar ph na najasar masana'antu a cikin tanki mai daidaitawa, sannan daidaita ƙimar ph na najasar masana'antu a cikin tankin hazo don hazo;

2) Ana jigilar dattin masana'antu da aka haɓaka zuwa tankin al'adun ƙananan ƙwayoyin cuta don maganin oxidation na microbial, kuma ana ƙara sodium acetate a cikin tsarin sufuri azaman tushen carbon na ƙwayoyin cuta;

3) Ruwan sharar gida na masana'antu bayan maganin oxidation na microbial yana haɓaka a karo na biyu don samun fitowar ruwa mai tsabta. Don haka, ana magance matsalar flammable da fashewar methanol a matsayin tushen carbon, kuma farashin ya yi ƙasa da na methanol, sitaci, glucose, da sauransu.

Aikace-aikacen sodium acetate a matsayin tushen carbon na waje a cikin tsire-tsire masu kula da najasa yana da matakai masu zuwa:

1) Daidaita ƙimar ph na najasar masana'antu a cikin tanki mai daidaitawa, da haɓaka najasar masana'antu bayan daidaita ƙimar ph a cikin tanki mai daidaitawa;

2) Shigar da najasar masana'antu da aka haɗe zuwa tankin al'adun ƙananan ƙwayoyin cuta don maganin oxidation microbial, kuma ƙara sodium acetate a matsayin tushen carbon na ƙwayoyin cuta a cikin tsarin sufuri. Ƙarin adadin sodium acetate shine 5 (Ne Ns) / 0.68 kowace lita na najasa. Ne najasa shine abun ciki na nitrogen da ake fitarwa a halin yanzu mg/l, kuma Ns najasa shine abun ciki na nitrogen mg/l a cikin ma'aunin aiwatarwa. 0.68 shine COD daidai darajar sodium acetate;

3) Ruwan sharar gida na masana'antu bayan maganin oxidation na microbial yana haɓaka a karo na biyu don samun fitowar ruwa mai tsabta.
