    The concentration of biomass in aeration tank can be increased to 6g/L and the removal rates of COD Cr and ammonia can also be improved by adding carrier to ordinal aeration tank. When the HRT is 8h and the sludge age is 5d, the removal rates of COD Cr and ammonia are increased by 20% and 9.6% respectively. The influence of hydraulic retention time on nitrification in hybrid biological reactor is less than in conventional activated sludge process.

  nitrification
Low levels of NO3- in these forest soils generally correspond to low net rates of nitrification.
      
Nitrification and denitrification in subalpine coniferous forests of different restoration stages in western Sichuan, China
      
Nitrification is the biological conversion of organic or inorganic nitrogen compounds from a reduced to a more oxidized state.
      
The results showed that forest restoration stage had no significant effects on gross nitrification rates or denitrification rates (One-way ANOVA (analysis of variance), p >amp;lt; 0.05).
      
There was no significant difference in the temperature coefficient (Q10) for gross nitrification rate among all the forest sites (One-way ANOVA, p >amp;lt; 0.05).
