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,
Iimpawu eziphambili:
Umxholo: ≥20%, ≥25%, ≥30%
Ukubonakala: ulwelo olucacileyo nolucacileyo, akukho vumba elicaphukisayo.
Izinto ezinganyibilikiyo zamanzi: ≤0.006%

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.

Ukucaciswa komgangatho

Ukusetyenziswa kwe-acetate ye-sodium njengomthombo wekhabhoni owongezelelweyo kwizityalo zokucoca amanzi amdaka kubandakanya la manyathelo alandelayo

1) Ukulungelelanisa ixabiso le-ph lamanzi amdaka avela kwimizi-mveliso kwitanki elawulayo, kwaye emva koko ulungelelanise ixabiso le-ph le-ph ye-lindle lemizi-mveliso kwitanki yogutyulo ukuze kubekho imvula;

I-2) Ukungcola kwamashishini okugqithisiweyo kuthuthwa kwi-tank yenkcubeko ye-microbial yonyango lwe-microbial oxidation, kunye ne-acetate ye-sodium yongezwa kwinkqubo yokuthutha njengomthombo wekhabhoni we-microorganisms;

I-3) Amanzi amdaka amashishini emva kokunyangwa kwe-microbial oxidation iyancipha okwesibini ukufumana ukukhutshwa kwamanzi acacileyo. Ngaloo ndlela, ingxaki yokutsha kunye nokuqhuma kwe-methanol njengomthombo wekhabhoni ixazululwe, kwaye iindleko ziphantsi kune-methanol, isitashi, i-glucose, njl.

Ukusetyenziswa kwe-acetate ye-sodium njengomthombo wekhabhoni yangaphandle kwizityalo zokucoca ugutyulo lubonakaliswa ngamanyathelo alandelayo:

1) Ukulungelelanisa ixabiso le-ph lamanzi amdaka avela kwimizi-mveliso kwitanki elawulayo, kunye nokunciphisa amanzi amdaka avela kwimizi-mveliso emva kokulungelelanisa ixabiso le-ph kwitanki yokulungisa;

2) Ukuthuthwa kwamanzi amdaka emizi-mveliso ukuya kwitanki yenkcubeko ye-microbial yonyango lwe-microbial oxidation, kunye nokongeza i-acetate ye-sodium njengomthombo wekhabhoni we-microorganisms kwinkqubo yokuthutha. Isixa esongezelelweyo se-acetate ye-sodium yi-5 (Ne Ns) / 0.68 ngelitha yamanzi amdaka. Ugutyulo lwamanzi amdaka akhoyo ngoku luqulathe lwenitrogen mg/l, kwaye ilindle leNs ngumxholo wenitrogen mg/l kumgangatho wokuphunyezwa. I-0.68 yi-COD yexabiso elilinganayo le-acetate ye-sodium;

I-3) Amanzi amdaka amashishini emva kokunyangwa kwe-microbial oxidation iyancipha okwesibini ukufumana ukukhutshwa kwamanzi acacileyo.
