In the process of social and economic development, the process of urbanization is also accelerating. Environmental engineering has become an important task to ensure the urban environment and the quality of people’s living and living, and is also a key link to achieve urban layout optimization. Due to the late start of environmental engineering in China, there are still many problems to be solved. Based on China’s actual national conditions, this paper classifies the identified security risks and builds a safety evaluation index system for urban sewage treatment plants. Finally, the analytic hierarchy process is used to construct the importance model of security risk factors, and the importance ranking of the main security risk factors is obtained.
