Ukusetyenziswa kwe-acetate ye-sodium kwisityalo sokunyanga kwamanzi amdaka
Ukusetyenziswa kwe-acetate yesodium kwisityalo sokunyanga amanzi amdaka,
Isisombululo se-acetate saseTshayina, Abathengisi baseTshayina be-sodium acetate, I-Sodium Acetate, iziphumo ze-sodium acetate, iziphumo ze-acetate ye-sodium kunye nokusetyenziswa, Abavelisi be-acetate yesodium, Isisombululo se-Sodium Acetate, abavelisi besisombululo se-sodium acetate, ababoneleli be-sodium acetate, ukusetyenziswa kwe-sodium acetate,
1. Iimpawu eziphambili:
Umxholo: ≥20%, ≥25%, ≥30%
Ukubonakala: ulwelo olucacileyo nolucacileyo, akukho vumba elicaphukisayo.
Izinto ezinganyibilikiyo zamanzi: ≤0.006%
2. Injongo ephambili:
Ukunyanga i-sewage yasezidolophini, funda impembelelo yobudala be-sludge (SRT) kunye nomthombo wangaphandle wekhabhoni (isisombululo se-acetate ye-sodium) kwi-denitrification yenkqubo kunye nokususwa kwe-phosphorus. I-acetate ye-sodium isetyenziswe njengomthombo wekhabhoni eyongezelelweyo ukuze kugcinwe i-denitrification sludge, kwaye emva koko isebenzise isisombululo se-buffer ukulawula ukunyuka kwe-pH ngexesha lenkqubo ye-denitrification ngaphakathi koluhlu lwe-0.5. Iibhaktheriya ezichazayo zinokubhengeza i-CH3COONA ngokugqithisileyo, ngoko ke xa usebenzisa i-CH3COONA njengomthombo wekhabhoni wangaphandle we-denitrification, ixabiso le-COD elimdaka nalo linokugcinwa kwinqanaba eliphantsi. Okwangoku, ukucocwa kwamanzi amdaka kuzo zonke izixeko kunye neengingqi kufuneka zongeze i-acetate ye-sodium njengomthombo wekhabhoni ukuhlangabezana nemigangatho yokukhutshwa kwenqanaba lokuqala.

I-acetate ye-sodium idlala indima ebalulekileyo ekulawuleni ixabiso le-PH kunyango lwamanzi amdaka. I-acetate ye-sodium yikhemikhali ye-alkaline enokuthi ifakwe nge-hydrolyzed ukwenza i-OH-negative ions emanzini, enokuthi i-neutralize ion ze-bai acid emanzini, njenge-H +, i-NH4 +, njl. , kodwa ngaba uyazi ukuba isetyenziswa njani? Namhlanje, uhlelo oluncinci lweHebei Pengfa luyakuxoxa nawe.
Okokuqala, i-acetate yesodium ayizange isetyenziswe ekuqaleni kwishishini lokunyanga amanzi, yayisoloko isetyenziswa kushishino lokuprinta nokudaya. Kungenxa yokuba imboni yokucocwa kwamanzi amdaka ikhula kwiminyaka yakutshanje, kwaye kukho imfuneko yokwenyani ye-acetate yesodium ukuze kuphuculwe injongo yokucocwa kogutyulo. Yiyo loo nto isetyenziswa kwishishini logutyulo. I-acetate ye-sodium isetyenziswe njengomthombo wekhabhoni eyongezelelweyo ukuqhelanisa i-denitrification sludge, kwaye isisombululo se-buffer sasetyenziswa ukulawula ukunyuka kwexabiso le-pH kwinkqubo ye-denitrification ngaphakathi kwe-0.5 uluhlu. Iibhaktheriya ze-Denitrifying zinokufunxa ngokugqithisileyo i-CH3COONa, ngoko ke ixabiso le-COD lamanzi amdaka linokugcinwa kwinqanaba eliphantsi xa i-CH3COONA isetyenziswa njengomthombo wekhabhoni owongezelelweyo we-denitrification. Okwangoku, yonke idolophu kunye ne-county ye-sewage yonyango ukuhlangabezana nemigangatho yokukhupha idinga ukongezwa kwe-acetate ye-sodium (i-acetate ye-sodium) njengomthombo wekhabhoni.
