Wace rawa sodium acetate ke takawa wajen kula da najasa

Wace rawa sodium acetate ke takawa wajen 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.

Yana taka muhimmiyar rawa wajen daidaita ƙimar PH na najasa. Sodium acetate wani abu ne na sinadari na alkaline wanda za'a iya sanya shi cikin ruwa don samar da ions OH-kore a cikin ruwa, wanda zai iya kawar da ions acidic a cikin ruwa, kamar H+ da NH4+. Ma'auni na hydrolysis na sodium acetate shine CH3COO-+ H2O = mai juyawa = CH3COOH + OH-

amfani

1. Ƙaddamar da gubar, zinc, aluminum, iron, cobalt, antimony, nickel da tin. Complex stabilizer. Auxiliary wakili na acetylation, buffer, desiccant, mordant.

2, ana amfani dashi don tantance gubar, zinc, aluminum, iron, cobalt, antimony, nickel, tin. An yi amfani da shi azaman wakili na esterification don haɓakar kwayoyin halitta da magungunan hoto, magani, bugu da rini mordant, wakili mai buffer, reagent sinadarai, anticorrosion nama, pigment, fata tanning da sauran fannoni da yawa.

3, wanda aka yi amfani da shi azaman mai buffering, wakili na kayan yaji, mai haɓaka ƙamshi da ph regulator. A matsayin wakili na buffering, yana iya rage warin da ba a so da kuma hana canza launi don inganta dandano lokacin amfani da 0.1% ~ 0.3%. Yana da wasu tasirin tabbacin mildew, kamar amfani da 0.1% ~ 0.3% a cikin kayan niƙan kifi da burodi.

4, wanda aka yi amfani da shi azaman sulfur mai sarrafa neoprene roba coking wakili, sashi shine gabaɗaya 0.5 taro. Hakanan za'a iya amfani da shi azaman wakili mai haɗin gwiwa don manne dabba.

5, ana iya amfani da wannan samfurin don ƙarar tin alkaline plating, amma ba shi da wani tasiri mai mahimmanci akan tsarin plating da plating, ba wani abu ba ne. Sodium acetate ana yawan amfani da shi azaman buffer, kamar a cikin galvanizing acid, plating tin alkaline da nickel plating mara amfani.
