Emergency control system based on the analytical hierarchy process and coordinated development degree model for sudden water pollution accidents in the Middle Route of the South-to-North Water Transfer Project in China

Abstract

Water transfer projects are important for realizing reasonable allocation of water resources, but once a water pollution accident occurs during such a project, the water environment is exposed to enormous risks. Therefore, it is critical to determine an appropriate emergency control system (ECS) for sudden water pollution accidents that occur in water transfer projects. In this study, the analytical hierarchy process (AHP) integrated with the coordinated development degree model (CDDM) was used to develop the ECS. This ECS was developed into two parts, including the emergency risk assessment and the emergency control. Feasible emergency control targets and control technology were also proposed for different sudden water pollution accidents. A demonstrative project was conducted in the Fangshui to Puyang channel, which is part of the Beijing-Shijiazhuang Emergency Water Supply Project (BSP) in the Middle Route of the South-to-North Water Transfer Project (MR-SNWTP) in China. However, we could not use an actual toxic soluble pollutant to validate our ECS, so we performed the experiment with sucrose to test the ECS based on its concentration variation. The relative error of peak sucrose concentration was less than 20 %.

Introduction - Emergency Operation Technologies for Sudden Water Pollution Accidents

“…Lian et al [25] built a 2D hydrodynamic water quality model based on CE-QUAL-W2 at the Three Gorges Reservoir and put forward different scheduling rules for the Three Gorges Reservoir to inhibit the outbreak of algal blooms according to the simulation results. Long et al [26] established a joint emergency scheduling model for canals where an accident occurred and upstream and downstream sections thereof based on the risk evaluation of sudden water pollution accidents in the MRP. Xu et al [27] set up a rapid emergency scheduling model for canals where an accident occurred in the MRP and put forward the method to operate two check gates in such canals.…”

Integrated Assessment Method of Emergency Plan for Sudden Water Pollution Accidents Based on Improved TOPSIS, Shannon Entropy and a Coordinated Development Degree Model

“…Lei et al (2018) [19] developed and implemented a decision support system that can provide technical support in managing pollution accidents. Xu et al (2016) [20] proposed a real-time, rapid emergency control mode. Wang et al (2018) [21] proposed a method for identifying pollution sources in rivers that could quickly control the spread of pollution.…”

The Spatial and Temporal Research on the Coupling and Coordinated Relationship between Social Economy and Energy Environment in the Belt and Road Initiatives

“…In contrast with EKC theory, the coupling coordinated development theory focuses on the relative status among two or more systems, but not on the absolute relationship among them [15]. Thus, this theory is widely applied to study the relationship among different systems [16][17][18][19]. In economy, environment, and energy (3E) research, the coupling coordinated degree model derived from the aforementioned theory is applied to explore the relationship among 3E systems.…”
