12. Nitrification and denitrification accord with the theory of maldistribution of DO and theory of deficiency of oxygen in microenvironment.

13. Denitrification gradually took over methanogenesis to become the main reaction responsible for decomposition of MSW while nitrogen gas, a clean byproduct, was generated instead.

14. There are substrata competition between the heterotrophic denitrification bacteria and ANAMMOX bacteria when organics the influent.

16. Advantages and disadvantages of the SNCR denitrification systems were separately compared by using different reactants, such as aqueous ammonia, anhydrous ammonia and urea etc.

17. Pulverized bark or even wood shavings can be used as it is so exposed to the air that denitrification is avoided.

18. Application of IFC at a proper rate can slightly accelerate ammonification and inhibit denitrification in the soil, and yet does not affect much microbial biomass in the soil.

19. Nitrate utilization rate test showed that the contents of organic compounds in raw wastewater were not sufficient for complete denitrification.
