Abstract:
In order to make a reasonable control programme of aeration and phosphorus removal, three years of historical monitoring data and supplementary test data were collected in the demonstration project of Dalingshan Lianma Wastewater Treatment Plant in Dongguan.Process model of the wastewater treatment plant was developed and calibrated by using GPS-X dynamic simulation software, and different process control scenarios were compared by dynamic simulation of the model. According to the simulation results, it was suggested that DO value should be set to control aeration in accordance with the change of ammonia nitrogen concentration, and phosphorus removal chemicals should be added at a fixed concentration to save energy and reduce consumption.
