In recent years, urbanization has been accompanied by the rapid development of population density and open space. People’s attention and understanding of water pollution issues have gradually increased, and the infrastructure of water pollution control (hereinafter referred to as WPC) has also developed rapidly. However, the increasing pressure of the water supply system, the shortage of water resources, the increase of household pollutant emissions, the pollution of rainwater runoff and the continuous deterioration of water environment quality have made the design, construction and technical selection of the WPC system face serious challenges. The current situation of water environment lies in the lack of theoretical guidance and system structure for the design and construction of the existing WPC system. This shows that it is difficult to solve the complex problems caused by the diversification of water pollution system technology and functional objectives. Based on this, this paper first analyzed the problems faced by the WPC system, focusing on the fact that the WPC technology has not formed a complete method and theoretical framework, the lack of systematic analysis of the WPC infrastructure construction, and the lack of analysis and assurance of the planning scheme of the WPC system. Then, this paper proposed the construction and application of robust optimization model in WPC system, and discussed the basic framework of robust optimization model and standard control system design. After that, the improved decision tree algorithm and robust optimization were proposed to strengthen the construction of WPC system. Through comparison, it can be seen that the pollution source control strength of the new WPC system was 0.34 higher than that of the traditional WPC system, and the water quality monitoring accuracy was 0.37 higher than that of the traditional WPC system. The system perfection under the new WPC system was 39.2% higher than that of the traditional WPC system, and the cost control effect was 48.2% higher than that of the traditional WPC system.
