Codsiga sodium acetate ee warshadda daweynta wasakhda

Codsiga sodium acetate ee warshadda daweynta wasakhda,
Xalka sodium acetate ee Shiinaha, Alaab-qeybiyeyaasha sodium acetate ee Shiinaha, Sodium acetate, saamaynta sodium acetate, Saamaynta iyo isticmaalka sodium acetate, Soosaarayaasha acetate sodium, Sodium Acetate Solution, soo saarayaasha xalalka acetate, alaab-qeybiyeyaasha sodium acetate, sodium acetate ayaa loo isticmaalaa,
1. Tilmaamayaasha ugu muhiimsan:
Waxa ku jira: ≥20%, ≥25%, ≥30%
Muuqashada: dareere cad oo hufan, ma laha ur cuncun leh.
Walxaha biyaha aan la milmi karin: ≤0.006%

2. Ujeedada ugu weyn:
Si loo daweeyo bulaacada magaalada, baro saamaynta da'da dhoobada (SRT) iyo isha kaarboonka ee dibadda (sodium acetate solution) ee nidaamka denitrification iyo ka saarista fosfooraska. Sodium acetate waxa loo isticmaalaa il kaarboon ah oo dheeri ah si loo demiyo dhoobada denitrification, ka dibna la isticmaalo xal kaydinta si loo xakameeyo korodhka pH inta lagu jiro habka denitrification gudahooda inta u dhaxaysa 0.5. Bakteeriyada diida waxay u adkeysan kartaa CH3COONa si xad dhaaf ah, sidaa darteed marka CH3COONa loo isticmaalo ilo kaarboon dibadda ah oo loogu talagalay denitrification, qiimaha COD ee wasakhaysan sidoo kale waxaa lagu ilaalin karaa heer hoose. Waqtigan xaadirka ah, daaweynta bulaacada ee dhammaan magaalooyinka iyo gobollada waxay u baahan yihiin inay ku daraan sodium acetate sida il kaarboon si ay ula kulmaan heerarka qiiqa heerka koowaad.

Sodium acetate waxay door muhiim ah ka ciyaartaa nidaaminta qiimaha PH ee daaweynta bulaacada. Sodium acetate waa maaddo kiimiko ah oo alkaline ah oo la hydrolyzed karo si ay u sameeyaan OH-negative ions ee biyaha, taas oo ka takhalusi karta ions bai acid ee biyaha, sida H+, NH4+, iwm. , laakiin ma garanaysaa sida loo isticmaalo? Maanta, daabacaadda yar ee Hebei Pengfa ayaa kaala hadli doonta.

Ugu horreyntii, sodium acetate markii hore looma isticmaalin warshadaha daaweynta biyaha, had iyo jeer waxaa loo isticmaali jiray warshadaha daabacaadda iyo midabaynta. Sababtoo ah warshadaha daaweynta bulaacada ayaa kor u kacaya sanadihii ugu dambeeyay, waxaana jira baahi dhab ah oo loo qabo sodium acetate si loo hagaajiyo bartilmaameedka daaweynta bulaacada. Taasi waa sababta loogu isticmaalo warshadaha bulaacada. Sodium acetate waxaa loo isticmaalay ilo kaarboon oo dheeri ah si loo kiciyo dhoobada denitrification, ka dibna xalka bakhaar ayaa la isticmaalay si loo xakameeyo kor u kaca qiimaha pH ee habka denitrification gudaha 0.5. Bakteeriyada diidista waxay si xad dhaaf ah u nuugi kartaa CH3COONa, markaa qiimaha COD ee wasakhda waxaa lagu hayn karaa heer hoose marka CH3COONa loo isticmaalo ilo kaarboon oo dheeraad ah oo loogu talagalay denitrification. Waqtigan xaadirka ah, dhammaan daaweynta bulaacada ee magaalada iyo degmada si loo buuxiyo heerarka dheecaanka waxay u baahan yihiin in lagu daro sodium acetate (sodium acetate) il kaarboon ahaan.
