Umsebenzi kunye nokusetyenziswa kwe-acetate ye-sodium kunyango lwamanzi amdaka
Umsebenzi kunye nokusetyenziswa kwe-acetate yesodium kunyango lwamanzi amdaka,
Ulwelo lweAcetate yeSodium, iziphumo zesodium acetate, abavelisi be-sodium acetate engamanzi, ukusetyenziswa kwe-sodium acetate yamanzi, Abavelisi be-acetate yesodium,
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.

Iimveliso ze-sodium sulfate zahlulwe zibe ziindidi kunye neentlobo ezimbini zolwelo, umxholo we-sodium acetate C2H3NaO2 ≥58-60%, imbonakalo: ikristale engenambala okanye emhlophe ecacileyo. Umxholo we-acetate ye-sodium yamanzi: umxholo ≥20%, 25%, 30%. Imbonakalo: Ulwelo olucacileyo nolucacileyo. Uluvo: akukho vumba elicaphukisayo, into enganyibilikiyo yamanzi: 0.006% okanye ngaphantsi.
Isicelo: I-acetate ye-sodium isetyenziswe njengomthombo wekhabhoni eyongezelelweyo kwizityalo zokucocwa kwamanzi amdaka ukuze zilungelelanise i-sludge ye-denitrification, enokufumana isantya esiphezulu se-denitrification. Okwangoku, lonke ugutyulo lwamanzi amdaka kamasipala okanye amashishini amdaka ukuhlangabezana nenqanaba lokukhutshwa A umgangatho ufuna ukongezwa kwe-acetate yesodium njengomthombo wekhabhoni.
1. Ubukhulu becala idlala indima yokulawula ixabiso le-PH yamanzi amdaka. Iyakwazi ukwenza i-hydrolyze emanzini ukwenza i-OH-negative ions, enokuthi i-neutralize ion acidic emanzini, njenge-H +, NH4 + njalo njalo. Inxaki ye-hydrolysis yile: CH3COO-+H2O= ebuyiselwa umva =CH3COOH+OH-.
2. Njengomthombo wekhabhoni eyongezelelweyo, isisombululo se-buffer sisetyenziselwa ukulawula ukunyuka kwexabiso le-pH ngaphakathi kwe-0.5 kwinkqubo ye-denitrification. 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. Ubukho be-acetate ye-sodium ngoku buthatha indawo yomthombo wekhabhoni yangaphambili, kwaye i-sludge yamanzi iba yinto esebenzayo emva kokusetyenziswa.
3. Idlala indima ebalulekileyo ekuzinzeni komgangatho wamanzi. Kwimibhobho ye-nitrite kunye ne-phosphorus, ingasetyenziselwa ukulungelelanisa umphumo, unokuphucula ukuqina kwe-corrosion inhibition. Ukuba uvavanyo lwenziwa kwimithombo yamanzi eyahlukeneyo, inani elincinci le-acetate ye-sodium ye-industrial grade ingasetyenziselwa kuqala ukufumana i-dosage efanelekileyo. Ngokuqhelekileyo, inkqubo yemveliso yeshishini iya kuba ngumlinganiselo oqinileyo kunye nomlinganiselo wamanzi we-1 ukuya kwi-5, ukugqiba inkqubo yokuchithwa ngaphambi kokuba ungeze amanzi okuxutywa.
