Aikace-aikacen sodium acetate a cikin injin tsabtace najasa
Yin amfani da sodium acetate a cikin masana'antar kula da najasa,
Maganin sodium acetate na kasar Sin, Masu samar da sodium acetate na kasar Sin, Sodium acetate, sodium acetate sakamako, sodium acetate sakamako da kuma amfani, Sodium acetate masana'antun, Sodium acetate Solution, sodium acetate bayani masana'antun, masu samar da sodium acetate, amfani da 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.

Sodium acetate yana taka muhimmiyar rawa wajen daidaita darajar PH a cikin maganin najasa. Sodium acetate wani abu ne na sinadari na alkaline wanda za'a iya sanya shi cikin ruwa don samar da OH- negative ions a cikin ruwa, wanda zai iya kawar da ions bai acid a cikin ruwa, irin su H+, NH4+, da dai sauransu. , amma ka san yadda ake amfani da shi? A yau, ƙaramin bugu na Hebei Pengfa zai tattauna da ku.
Da farko dai, ba a fara amfani da sinadarin sodium acetate a masana’antar sarrafa ruwa ba, ana amfani da ita a masana’antar bugu da rini. Kawai saboda masana'antar kula da najasa tana haɓaka a cikin 'yan shekarun nan, kuma akwai ainihin buƙatar sodium acetate don inganta manufar kula da najasa. Shi ya sa ake amfani da shi a masana’antar najasa. An yi amfani da Sodium acetate azaman ƙarin tushen carbon don haɓaka sludge denitrification, sannan aka yi amfani da maganin buffer don sarrafa haɓakar ƙimar pH a cikin tsarin denitrification tsakanin kewayon 0.5. Bakteriya mai hanawa na iya mamaye CH3COONa, don haka ana iya kiyaye ƙimar COD na ƙazanta a ƙaramin matakin lokacin da ake amfani da CH3COONa azaman ƙarin tushen carbon don ƙirƙira. A halin yanzu, duk maganin najasa na birni da gundumomi don saduwa da ƙa'idodin fitarwa yana buƙatar ƙari na sodium acetate (sodium acetate) azaman tushen carbon.
