摘　　要：结合重庆市某改良A^2/O工艺污水处理的工程实例,介绍了物联网技术和自动控制技术在系统中的应用方案及功能组成。使用物联网技术进行污水取样和相关参数测试,明确污水处理系统各功能部分的工作状态,使用三级计算机分散控制系统对污水处理过程进行实时信息化管理。运行结果表明,应用融合物联网的自动控制手段后,系统运行稳定性得到提升,数据采集测试频率可稳定维持在15 min/次,出水达标率>90%,耗电量<0.35 k W·h/m^3。According to a project case of the modified A^2/O process for wastewater treatment in Chongqing,the application project and function construction of the internet of things technique and automatic control technique to the system are introduced. The wastewater is sampled and relevant parameters are tested by the internet of things technique,to find out the working state of every functional part in the wastewater treatment system. Real-time information management has been implemented to the wastewater treatment process by the three-level computer distributed control system. The operation results show that the system operating stability is improved after applying the automatic control method combined with the internet of things. The data sampling and testing frequency keeps at 15 min per time,the standard-reaching rate of the effluent is over 90%,and power consumption rate is less than 0.35 k W·h/m^3.
