Umenzi wesisombululo se-sodium acetate, isenzo se-sodium acetate kunye nokusetyenziswa

umenzi wesisombululo se-sodium acetate, isenzo se-sodium acetate kunye nokusetyenziswa,
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,
Ulwelo sodium acetate
① Iimpawu eziphambili:
Umxholo: Umxholo ≥20%, 25%, 30% Imbonakalo: ulwelo olucacileyo noluselubala, isisombululo samanzi se-byproduct sicacile kwaye sityheli kancinci ngombala.
Isiva: akukho vumba licaphukisayo. Izinto ezinganyibilikiyo zamanzi: 0.006% okanye ngaphantsi

I-58% eqinileyo yokulungisa isisombululo samanzi esingama-25%:

Ngokomlinganiselo we-1 kg ye-acetate ye-sodium ukuya kwi-1.3 kg yamanzi, ukushisa kwamanzi kwindawo yokushisa kwegumbi malunga nama-degrees angama-20, izinga lokuchithwa lihamba kancinci kune-10 degrees.

Indawo yokukhenkceza ye-25% yesisombululo samanzi malunga ne-10 degrees.

② Eyona nto isetyenziswayo:

Indima ephambili ye-acetate yesodium elulwelo kunyango lwelindle kukongeza umthombo wekhabhoni ye-denitrifying bacteria, ukuqeqesha udaka lwe-denitrifying, kwaye emva koko usebenzise isisombululo se-buffer ukulawula ukunyuka kwexabiso le-pH kwinkqubo ye-denitrification ngaphakathi koluhlu lwe-0.5. 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, ukunyangwa kwamanzi amdaka kuzo zonke izixeko kunye neengingqi kufuneka zongeze i-acetate ye-sodium njengomthombo wekhabhoni ukuba ifuna ukuhlangabezana nenqanaba lokukhupha I-standard.

③ umgangatho wonikezelo:
Xa i-dosage ye-acetate ye-sodium i-15mg / L, i-concentration ye-outlet ye-parameter nganye yenkqubo inokuhlangabezana ne-"Standard Discharge of Polltants kwi-Urban Sewage Treatment Plant" i-GB18918-2002 i-Class A standard. Xa i-dosage yayiyi-30mg / L, izinga lokukhululwa kwe-phosphorus yecandelo le-anaerobic, izinga lokufunxa i-phosphorus yecandelo le-aerobic kunye nesantya sokususwa kwe-nitrogen yecandelo le-anoxic yonke yayiphezulu, enokufikelela kwi-3.54 MgPo43-p / (g MLSS · h) 2.54 mgPO43– P/(g MLSS·h). Kwaye 1.53 mgNOx-N/(gMLSS·h). Xa i-dosage ye-acetate ye-sodium yayingu-9mg / L kunye ne-15mg / L, i-denitrification kunye nokususwa kwe-phosphorus kwenzeka kwicandelo le-hypoxia, kwaye izinga lokufunxa i-phosphorus laliyi-0.36mgPO43-P / (g MLSS · h) kunye ne-0.02 (mgPO43-P / () gMLSS · h), ngokulandelelanayo, inkqubo iya kuzinza kwaye inokwethenjelwa xa idosi ye-acetate ye-sodium i-30mg / L.
