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,
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%

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.

Tilmaamaha tayada

Codsiga sodium acetate sida ilo kaarboon oo dheeri ah oo loogu talagalay dhirta daaweynta biyaha wasakhda waxaa ka mid ah tillaabooyinka soo socda

1) Hagaajin qiimaha ph ee bulaacada warshadaha ee haanta nidaaminta, ka dibna hagaaji qiimaha ph ee wasakhda warshadaha ee haanta roobabka;

2) bulaacada warshadaha ee degdega ah waxaa loo qaadaa taangiga dhaqanka microbial si loogu daweeyo oksaydheynta microbial, iyo acetate sodium waxaa lagu daraa habka gaadiidka sida isha kaarboon ee microorganisms;

3) Biyaha wasakhda ah ee warshadaha ka dib daawaynta oksaydheynta microbial ayaa soo degdegay mar labaad si loo helo dheecaan biyo nadiif ah. Haddaba, dhibka guban kara iyo kuwa qarxa ee methanol sida isha kaarboonka waa la xalliyaa, qiimuhuna wuu ka hooseeyaa kan methanol, istaarij, gulukoos, iwm.

Codsiga sodium acetate sida isha kaarboonka dibadda ee dhirta daaweynta bulaacada waxaa lagu gartaa tillaabooyinka soo socda:

1) Hagaajin qiimaha ph ee wasakhda warshadaha ee haanta nidaaminta, oo soo dedeji wasakhda warshadaha ka dib marka la hagaajiyo qiimaha ph ee haanta dejinta;

2) U rarida bulaacada warshadaha ee degdega ah taangiga dhaqanka microbial si loogu daweeyo oksaydheynta microbial, oo ku darsodiyam acetate sida isha kaarboon ee noolaha ee habka gaadiidka. Qadarka dheeriga ah ee sodium acetate waa 5 (Ne Ns) / 0.68 litirkii bulaacada. bulaacada nee waa dareeraha nitrogen ee hadda jira mg/l, iyo wasakhda Ns waa maadada nitrogen mg/l ee heerka fulinta. 0.68 waa COD qiimaha u dhigma ee sodium acetate;

3) Biyaha wasakhda ah ee warshadaha ka dib daawaynta oksaydheynta microbial ayaa soo degdegay mar labaad si loo helo dheecaan biyo nadiif ah.
