I-Fluidized bed filler, eyaziwa nangokuthi i-MBBR filler, iwuhlobo olusha lwesithwali se-bioactive. Yamukela ifomula yesayensi, ngokwezidingo ezihlukene zekhwalithi yamanzi, ihlanganisa izinhlobo ezahlukene zama-microelements ezintweni ze-polymer ezisiza ukukhula ngokushesha kwama-microorganisms ekunamathiselwe. Isakhiwo se-filler engenalutho siyisamba sezingqimba ezintathu zemibuthano engenalutho ngaphakathi nangaphandle, indilinga ngayinye ine-prong eyodwa ngaphakathi nama-prong angu-36 ngaphandle, ngesakhiwo esikhethekile, futhi isigcwalisi simisiwe emanzini ngesikhathi sokusebenza okujwayelekile. Amagciwane anaerobic akhula ngaphakathi kwesigcwali ukuze akhiqize i-denitrification; amagciwane e-aerobic akhula ngaphandle ukuze asuse izinto eziphilayo, futhi kukhona kokubili inqubo ye-nitrification ne-denitrification kuyo yonke inqubo yokwelapha. Ngezinzuzo zendawo enkulu ethile, i-hydrophilic kanye nokuhlangana okuhle kakhulu, umsebenzi ophezulu wezinto eziphilayo, ifilimu elenga ngokushesha, umphumela omuhle wokwelapha, impilo ende yesevisi, njll., kuyisinqumo esingcono kakhulu sokususa i-ammonia nitrogen, i-decarbonization kanye nokususwa kwe-phosphorus, ukuhlanzwa kwendle, ukusetshenziswa kabusha kwamanzi, i-COD ye-sewage deodorization, BOD ukuphakamisa izinga.
