Kedu oge njide tank nke MBBR tank?
MBBR (Moving Bed Biofilm Reactor) bụ teknụzụ ọgwụgwọ ndu na-arụ ọrụ nke ọma nke ejiri maka ọgwụgwọ mmiri na-ekpofu mmiri. Ọ na-ejikọta uru nke sludge na-arụ ọrụ na usoro biofilm site n'ịgbakwụnye ihe nkwụnye ọkụ na-ejuputa na reactor iji mee ka mgbakwunye na uto ohere maka microorganisms, si otú ahụ na-eme ka ọgwụgwọ dị mma.
Ngụkọ oge ndochi hydraulic
Oge njide hydraulic (HRT) na-ezo aka na nkezi oge obibi nke mmiri mkpofu na reactor. Usoro maka ịgbakọ oge njigide hydraulic nke ọdọ mmiri MBBR bụ nke a:
HRT {0}QV
Ebe:
V bụ olu dị irè nke reactor (m3), N'ịtụle na reactor adịghị ejupụta na mmiri kpamkpam na arụ ọrụ n'ezie, a na-ewerekarị olu kwekọrọ na omimi mmiri.
Q bụ ọnụ ọgụgụ na-erute mmetụta (m3/h).
Otu esi agbakọ oge Njide Sludge?
Oge Njide Sludge (SRT), makwaara dị ka oge njigide biomass, na-ezo aka na nkezi oge obibi nke biomass (sludge) na sistemụ.
N'ime usoro MBBR, ịgbakọ SRT ozugbo dị mgbagwoju anya n'ihi nkọwapụta nke sistemu ahụ (biofilm etinyere na filler kama kwụsịtụrụ na mmiri kpamkpam). A na-ejikwa SRT n'ụzọ na-edoghị anya site n'ịchịkwa sludge nke sistemu ahụ yana nyochaa ọkpụrụkpụ biofilm kama ịgbakọ ya ozugbo.
Maka usoro MBBR, n'ihi na ọtụtụ n'ime ọgwụgwọ ndị dị ndụ na-eme n'elu biofilm n'elu filler, arụmọrụ nke usoro ahụ na-adabere ọ bụghị nanị na oge njigide hydraulic kamakwa na ọkpụrụkpụ na ọrụ nke biofilm. Ya mere, isi ihe na-achịkwa na ịkwalite usoro MBBR abụghị nanị site n'ịgbakọ na ịhazigharị HRT kamakwa nlekota na ịnọgide na-enwe ahụike nke biofilm na filler.
Maka ngụkọ akọwapụtara nke ọma na atụmatụ sistemu, ihe ndị dị ka njirimara mmiri mkpofu, ebumnuche ọgwụgwọ, paramita imewe reactor, wdg, kwesịrị ịtụle. Ndozi na njikarịcha nwere ike ịchọ mmemme injinịa na ahụmịhe.
Maka sistemu ọgwụgwọ sludge arụ ọrụ nke ọdịnala, anyị nwere ike gbakọọ Oge Njide Sludge (SRT), makwaara dị ka Oge Njide siri ike (SST) ma ọ bụ Oge Njide Biomass. Nke a bụ ihe atụ mgbako dị mfe iji nyere gị aka ịghọta otu esi agbakọ SRT.

Ngụkọta SS nwere mmetụta=olu mmetụta × Mmetụta SS na-emetụta=10,000 m3/ ụbọchị × 200 mg / L

Ka anyị gbakọọ ụkpụrụ ndị akọwapụtara.
