Shaqada iyo codsiga sodium acetate ee daaweynta biyaha wasakhda ah

Shaqada iyo adeegsiga sodium acetate ee daaweynta biyaha wasakhda ah,
Sodium acetate dareere ah, dareeraha sodium acetate saamaynta, dareeraha soodhiyam acetate saarayaasha, dareeraha sodium acetate isticmaalo, Soosaarayaasha acetate sodium,
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.

Alaabooyinka sodium sulfate waxay u kala qaybsan yihiin laba nooc oo adag iyo dareere, sodium acetate adag C2H3NaO2 content ≥58-60%, muuqaal: crystal hufan oo aan midab lahayn ama cad. Waxyaabaha dareeraha ah ee sodium acetate: content ≥20%, 25%, 30%. Muuqaalka: dareere cad oo hufan. Dareen: ma laha ur cuncun leh, biyo aan milmi karin: 0.006% ama ka yar.

Codsiga: Sodium acetate waxaa loo isticmaalaa ilaha kaarboonka ee dheeriga ah ee dhirta lagu daweeyo bulaacada si ay u xoojiso dhoobada denitrification, taas oo heli karta heer sare oo denitrification gaar ah. Waqtigan xaadirka ah, dhammaan bulaacada degmada ama daaweynta biyaha wasakhda ah ee warshadaha si ay u buuxiyaan heerka dheecaanka Heerka A wuxuu u baahan yahay in lagu daro sodium acetate sida isha kaarboon.

1. Waxay inta badan ka ciyaartaa doorka nidaaminta qiimaha PH ee wasakhda. Waxay ku shubi kartaa biyaha si ay u samaysato ion OH-negative ah, kuwaas oo ka takhalusi kara aions acidic ee biyaha, sida H+, NH4+ iyo wixii la mid ah. Isla'egta hydrolysisku waa: CH3COO-+H2O= dib loo rogi karo =CH3COOH+OH-.

2. Sida ilaha kaarboonka ee dheeriga ah, xalinta kaydinta waxaa loo isticmaalaa in lagu xakameeyo kor u kaca qiimaha pH gudaha 0.5 ee habka denitrification. 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. Joogitaanka sodium acetate hadda waxay bedeshaa il kaarboon hore, iyo dhoobada biyuhu waxay noqotaa mid firfircoon ka dib isticmaalka.

3. Waxay door muhiim ah ka ciyaartaa xasiloonida tayada biyaha. Biyaha wasakhda ah ee nitrite iyo fosfooraska, waxaa loo isticmaali karaa saameynta isuduwidda, taas oo hagaajin karta xoojinta xakamaynta daxalka. Haddii tijaabada lagu sameeyo ilo biyo oo kala duwan, qadar yar oo ah heerka warshadaha sodium acetate ayaa marka hore loo isticmaali karaa si loo helo qiyaasta ku habboon. Sida caadiga ah, habka wax soo saarka ee shirkadu waxay noqon doontaa saamiga adag iyo biyaha ee 1 ilaa 5, si loo dhamaystiro habka kala dirida ka hor inta aan lagu darin biyaha lagu qasi karo.
