down if the bioreactor landfill was to be operated for in situ nitrogen removal. During the initial stage, the leachate from the BLF and NBLF did not exhibit long-term COD accumulation and depression of pH, indicating that the hydrolyzed products could be consumed and/or removed as fast as they produced. Over a refuse reactor balance of leachate COD could be stated as follows
COD out=COD hydrolyzed+COD in — COD consumed;
where the COD consumed included the organic carbon assimilated by microbes, transformed into gas phase and lost in sampling. The COD attenuations of the BLF and NBLF went through two stages and degradation rate chan- ged significantly, which might be explained by the expres- sions. During the first stage, the COD attenuation rate of S4 was slower than that of S5. Based on the well established principle that pH (<6.0) in leachate was an effective inhib- itor of methanogenesis (Chynoweth et al., 1992), the COD consumed by microbial assimilation and transformation into CO2 was also little and negligible in the first stage. Meanwhile, the input COD also could be negligible be- cause the BLF and NBLF were circulated with S2 and S3 those containing little organic matter. Consequently, the interaction that refuse dissolved (or hydrolyzed) into leach- ate and recirculation caused dilution resulted in COD change of S4. In contrast to the BLF, denitrification proceeded in the NBLF. Thus, it was the interactions that dissolution (or hydrolysis) of solid refuse into leachate, dilution by recirculation and organic consumption led to the COD change of S5. The COD attenuation was mostly decided by solid refuse hydrolysis in either S4 or S5.
