Ukusetshenziswa kwe-acetate ye-sodium endaweni yokuhlanza indle

Ukusetshenziswa kwe-sodium acetate endaweni yokuhlanza indle,
Isixazululo se-Chinese sodium acetate, Abahlinzeki be-Chinese sodium acetate, I-Sodium Acetate, imiphumela ye-sodium acetate, imiphumela ye-sodium acetate kanye nokusetshenziswa, Abakhiqizi be-sodium acetate, Isixazululo se-Sodium Acetate, abakhiqizi besisombululo se-sodium acetate, abahlinzeki be-sodium acetate, ukusetshenziswa kwe-sodium acetate,
Izinkomba eziyinhloko:
Okuqukethwe: ≥20%, ≥25%, ≥30%
Ukubukeka: uketshezi olucacile futhi olusobala, alukho iphunga elicasulayo.
Amanzi angancibiliki: ≤0.006%

Injongo eyinhloko:
Ukwelapha indle yasemadolobheni, funda umthelela weminyaka yodaka (SRT) kanye nomthombo wekhabhoni wangaphandle (isixazululo se-acetate ye-sodium) ekukhishweni kwesistimu nokususwa kwe-phosphorus. I-sodium acetate isetshenziswa njengomthombo wekhabhoni yokwengeza ukuze kufuywe udaka lwe-denitrification, bese kusetshenziswa isisombululo se-buffer ukulawula ukwanda kwe-pH phakathi nenqubo yokukhishwa kwe-denitrification phakathi kwebanga elingu-0.5. Ibhaktheriya ehlukanisayo ingakhanga i-CH3COONa ngokweqile, ngakho-ke uma usebenzisa i-CH3COONA njengomthombo wekhabhoni yangaphandle ukuze i-denitrification, inani le-COD elingcolile lingagcinwa lisezingeni eliphansi. Njengamanje, ukuhlanzwa kwendle kuwo wonke amadolobha nezifunda kudinga ukwengeza i-sodium acetate njengomthombo wekhabhoni ukuze kuhlangatshezwane namazinga okuphuma kwezinga lokuqala.

Ukucaciswa kwekhwalithi

Ukusetshenziswa kwe-sodium acetate njengomthombo owengeziwe wekhabhoni wezitshalo zokuhlanza amanzi angcolile kubandakanya izinyathelo ezilandelayo

1) Lungisa inani elingu-ph lokukhucululwa kwendle ezimbonini ethangini elilawulayo, bese ulungisa inani elingu-ph lokukhucululwa kwendle ezimbonini ethangini lemvula ukuze kunemvula;

I-2) Indle encishisiwe yezimboni ithuthelwa ku-tank yesiko le-microbial yokwelashwa kwe-microbial oxidation, futhi i-acetate ye-sodium yengezwa ohlelweni lokuthutha njengomthombo wekhabhoni wezinto ezincane;

I-3) Amanzi angcolile ezimbonini ngemva kokwelashwa kwe-microbial oxidation ancipha okwesibili ukuze kutholwe ukuchithwa kwamanzi acacile. Ngakho-ke, inkinga evuthayo futhi eqhumayo ye-methanol njengomthombo wekhabhoni iyaxazululwa, futhi izindleko ziphansi kune-methanol, isitashi, i-glucose, njll.

Ukusetshenziswa kwe-sodium acetate njengomthombo wekhabhoni wangaphandle ezitshalweni zokuhlanza indle kubonakala ngezinyathelo ezilandelayo:

1) Lungisa inani elingu-ph lokukhucululwa kwendle ezimbonini ethangini elilawulayo, bese unciphisa indle yasezimbonini ngemva kokulungisa inani elingu-ph ethangini lokulungisa;

2) Thutha indle enciphile yezimboni uyiyise ethangini le-microbial culture ukuze kuhlanzwe i-microbial oxidation, bese wengeza i-sodium acetate njengomthombo wekhabhoni wama-microorganisms ohlelweni lokuthutha. Inani elingeziwe le-sodium acetate ngu-5(Ne Ns)/0.68 ilitha ngalinye lendle. I-Ne sewage ingumthamo wamanje we-nitrogen engcolile engu-mg/l, kanti indle ye-Ns ingukuqukethwe kwe-nitrogen mg/l ezingeni lokusetshenziswa. I-0.68 inani elilinganayo le-COD le-acetate ye-sodium;

I-3) Amanzi angcolile ezimbonini ngemva kokwelashwa kwe-microbial oxidation ancipha okwesibili ukuze kutholwe ukuchithwa kwamanzi acacile.
