Published: May 2014

Based on the Nagel-Schrekenberg (NaSch) model, a cellular automation model is proposed to describe the mixing traffic flow in a single-lane roundabout with open boundary condition. In this model, the impact of the injection probability and the mixed proportion coefficient on the mixed traffic flow is emphatically studied. Simulation results indicate that the injection probability can change the system density, velocity and flow in a certain range for a constant mixed proportion coefficient. Moreover, for a fixed injection probability, when the injection probability is lower than the critical level, the system average velocity will be more affected by the mixed proportion coefficient, By contrast, the system flow will not change by the mixed proportion coefficient; When the injection probability is higher than the critical level, the mixed proportion coefficient can only change the system density, average velocity and flow in a small range.

Authors: Li An Feng , Ning Yan Ying , Xu Wen Jiang , Pan Tao
Published: May 2014

High concentrations of ammoniacal nitrogen in fecal sewage pose a great threat to subsequent treatment steps. The conventional removal technique in China mainly involves air stripping. However, the concentration of ammonia in the effluent is often very high, and the fillers in towers could exhibit scaling resulting in reduced lifetime in operation. Because of its high mass transfer characteristics, fluidized bed technology was used in our study of the air stripping method for improving the removal efficiency, using spherical biological ceramsites as the filler. The effects of temperature, pH, and fluidized bed residence time on the removal process were investigated. To compare the various effects of fluidized bed operation on nitrogen removal efficiency, traditional air stripping experiments were carried out using the identical gas flowrate, liquid flowrate, temperature and pH. The results show that the removal efficiency of ammoniacal nitrogen was improved using a fluidized bed. The mechanism of free ammonia mass transfer using fluidized bed technology was proposed. Finally, the filler adhesion problem was reduced and the technology was successfully applied to the air stripping of high concentration ammoniacal nitrogen from fecal sewage.
