The results obtain through varying the recycle ratio, the hydraulic retention time and the recirculation ratio between reactors show that BOD removal efficiency of organic matter and nitrogen removal efficiency are above 93%, 88% respectively, and the denitrification efficiency is above 85% when C/N ratio and H/A ratio are above 5 and 3,16, respectively.
The biological fluidized bed obtains 93% BOD removal in 48min, at 87% NH4+-N removal in32min, and at 84% NO3--N removal at each reactor.
