Ayyuka da aikace-aikacen sodium acetate a cikin maganin ruwa mai tsabta
Aiki da aikace-aikace na sodium acetate a cikin sharar gida magani,
Liquid sodium acetate, ruwa sodium acetate effects, ruwa sodium acetate masana'antun, ruwa sodium acetate amfani, Sodium acetate masana'antun,
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 sulfate kayayyakin sun kasu kashi biyu m da ruwa iri biyu, m sodium acetate C2H3NaO2 abun ciki ≥58-60%, bayyanar: crystal m ko fari m. Liquid sodium acetate abun ciki: abun ciki ≥20%, 25%, 30%. Bayyanar: ruwa mai haske kuma bayyananne. Sensory: babu wari mai ban haushi, ruwa maras narkewa: 0.006% ko ƙasa da haka.
Aikace-aikace: Ana amfani da sodium acetate azaman ƙarin tushen carbon a cikin tsire-tsire masu kula da najasa don haɓaka sludge denitrification, wanda zai iya samun ƙimar ƙima ta musamman. A halin yanzu, duk najasa na birni ko na masana'antu don saduwa da matakin fitarwa A misali yana buƙatar ƙarin sodium acetate azaman tushen carbon.
1. Yafi taka rawa wajen daidaita darajar PH na najasa. Yana iya yin ruwa a cikin ruwa don samar da ions na OH-negative, wanda zai iya kawar da ions acidic a cikin ruwa, kamar H+, NH4+ da sauransu. Ma'aunin hydrolysis shine: CH3COO-+H2O= mai juyawa = CH3COOH+OH-.
2. A matsayin ƙarin tushen carbon, ana amfani da maganin buffer don sarrafa haɓakar ƙimar pH a cikin 0.5 a cikin aikin denitrification. 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. Kasancewar sodium acetate yanzu ya maye gurbin tushen carbon na baya, kuma sludge na ruwa ya zama mafi aiki bayan amfani.
3. Yana taka muhimmiyar rawa a cikin kwanciyar hankali na ingancin ruwa. A cikin najasa na nitrite da phosphorus, ana iya amfani dashi don tasirin daidaitawa, wanda zai iya inganta ƙarfin hana lalata. Idan an gudanar da gwajin a kan maɓuɓɓugar ruwa daban-daban, za a iya amfani da ƙaramin adadin sodium acetate na masana'antu da farko don samun adadin da ya dace. Yawancin lokaci, tsarin samar da kamfani zai kasance mai ƙarfi da ruwa na 1 zuwa 5, don kammala aikin rushewa kafin ƙara ruwa don dilution.
