[Treatment of ANAMMOX technique on treating high concentration poultry wastewater].
Taking the effluent of the UASB-shortcut nitrification technique of typical high concentration poultry wastewater as the object, it is discussed that the ANAMMOX is applicable as a treatment of denitrification. Firstly, it successfully starts ANAMMOX reactor by the denitrifying activated sludge, on this basis, finding the optimal ammonia loading is about 0.2 kg/(m3 x d) and the HRT of system is 2 d. Moreover, after studyingon the operating conditions, the optimum is that pH is about 7.50; temperature is 30 degrees C without adding organic carbon. Under optimum conditions, the removal efficiencies of ammonia and nitrite nitrogen could be above 85% and 95%, the system is running well and has reproducibility. Finally, it reaches that the reaction rates of ammonia and nitrite nitrogen are 0.0126 d(-1) and 0.0131 d(-1) through dynamic analysis. So it can make the theory basis for spreading and application of after/continuous process, neural network simulation and "UASB + SBR shortcut nitrification + ANAMMOX + land treating system" newly combined process.
