摘要/Abstract

摘要： In this article, a steady-state mathematical model was developed and experimentally
evaluated to investigate the effect of influent flow distribution and volume ratios of
anoxic and aerobic zones in each stage on the total nitrogen concentration of the effluent
in the step-feed biological nitrogen removal process. Unlike the previous modeling methods,
this model can be used to calculate the removal rates of ammonia and nitrate in each stage
and thereby predict the concentrations of ammonia, nitrate, and total nitrogen in the
effluent. To verify the simulation results, pilot-scale experimental studies were carried
out in a four-stage step feed process. Good correlations were achieved between the measured
data and the simulation results, which proved the validity of the developed model. The
sensitivity of the model predictions was analyzed. After verification of the validity, the
step feed process was optimally operated for five months using the model and the criteria
developed for the design and operation. During the pilot-scale experimental period, the
effluent total nitrogen concentrations were all below 5mg•L－1, with more than 90% removal
efficiency.
