Umkhiqizi wesisombululo se-sodium acetate, isenzo se-sodium acetate nokusetshenziswa

Umkhiqizi wesisombululo se-sodium acetate, isenzo nokusetshenziswa kwe-sodium acetate,
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,
I-acetate ye-sodium ewuketshezi
① Izinkomba eziyinhloko:
Okuqukethwe: Okuqukethwe ≥20%, 25%, 30% Ukubukeka: uketshezi olucacile futhi olusobala, isixazululo samanzi somkhiqizo sicacile futhi siphuzi kancane ngombala.
Izinzwa: alikho iphunga elicasulayo. Izinto ezingancibiliki emanzini: 0.006% noma ngaphansi

58% okuqinile ukulungisa amanzi angama-25%:

Ngokwesilinganiso se-1 kg ye-acetate ye-sodium kuya ku-1.3 kg wamanzi, izinga lokushisa lamanzi ekamelweni lokushisa lingama-degree angu-20, izinga lokuchithwa lihamba kancane kune-10 degrees.

Iphuzu eliqandayo lika-25% lesisombululo esinamanzi licishe libe ngu-10 degrees.

② Ukusetshenziswa okuyinhloko:

Indima eyinhloko ye-sodium acetate ewuketshezi ekuhlanzeni indle ukunezela umthombo wekhabhoni wamagciwane ahlukanisayo, ukuqeqesha udaka lwe-denitrifying, bese usebenzisa isisombululo se-buffer ukulawula ukukhuphuka kwe-pH yenqubo yokukhishwa kwe-denitrification phakathi kwebanga elingu-0.5. I-Denitriifying bacteria ingamunca ngokweqile i-CH3COONa, ngakho-ke inani le-COD lamanzi angcolile lingagcinwa lisezingeni eliphansi lapho i-CH3COONA isetshenziswa njengomthombo owengeziwe wekhabhoni wokukhishwa kwe-denitrification. Njengamanje, ukuhlanzwa kwendle kwawo wonke amadolobha nezifunda kudinga ukwengeza i-acetate ye-sodium njengomthombo wekhabhoni uma ifuna ukuhlangabezana nezinga lokukhishwa kwe-I.

③ Izinga lokulethwa:
Uma isilinganiso se-sodium acetate singu-15mg/L, ukugxilwa kwe-outlet yepharamitha ngayinye yesistimu kungahlangabezana ne-“Discharge Standard of Pollutants from Urban Sewage Treatment Plant” GB18918-2002 Class A standard. Lapho umthamo wawungu-30mg/L, izinga lokukhululwa kwe-phosphorus lesigaba se-anaerobic, izinga lokumuncwa kwe-phosphorus lesigaba se-aerobic kanye nezinga lokususwa kwe-nitrogen lesigaba se-anoxic konke kwakuphakeme, okungafinyelela ku-3.54 MgPo43-p / (g MLSS·h) 2.54 mgPO43– P/(g MLSS·h). Futhi 1.53 mgNOx-N/(gMLSS·h). Lapho umthamo we-sodium acetate wawungu-9mg/L no-15mg/L, i-denitrification kanye nokususwa kwe-phosphorus kwenzeka esigabeni se-hypoxia, futhi amazinga okumuncwa kwe-phosphorus ayengu-0.36mgPO43–P/(g MLSS·h) kanye ne-0.02(mgPO43–P/( gMLSS·h), ngokulandelana, isistimu izozinza kakhulu futhi ithembeke lapho umthamo we-sodium acetate ingu-30mg/L.
