- 摘要:
- 为了制定合理的曝气和除磷加药控制方案，以东莞大岭山连马污水处理厂作为示范，收集了该厂3年的历史监测数据及补充数据，利用污水处理厂模拟软件GPS-X建立并校正了污水处理工艺模型，利用动态模拟对比不同工艺控制方案，根据模拟结果建议按氨氮浓度变化设定DO值进行曝气控制；采用固定加药浓度投加除磷药剂，从而实现节能降耗。
- 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.
