Optimization of AmOn Integrative Nutrients Removal Reactor Based on Numerical Simulation

Abstract

The aim of this study is to analisis the method of estabishing a model of AmOn integrative nutrients removal reactor, and based on the results of experiments, to optimize the operating conditions as well. The ASM mechanisms and WEST software were unilized in the model. Results showed that the relatively errors of COD, NH3-N, TN and TP between value of experiment and simulated are 7.2%, 9.1%, 12.5% and 6.3%, respectively. The values ranges of operating parameters are: gas/liquid ratio is between 20∶1–30∶1, and C/N is above 10∶1. A good method of simulating AmOn reactor is found and validated. The model offers a theory base which can using AmOn integrative reactor in practical more effectively.
