In order to deal with the possible sudden water pollution incidents of the South-to-North Water Diversion Project,a technical system of sudden water pollution emergency regulation and treatment was established,which integrates the five links of numerical simulation,evaluation and diagnosis,tracing prediction,emergency regulation,and pollution treatment.This system includes water quantity and quality simulation technology,water quality safety evaluation and diagnosis technology,sudden water pollution tracing prediction technology,water pollution emergency regulation technology,and water pollution emergency treatment technology.The results could be applied to demonstration project and system platform,ensure water quality safety of the main of middle routes of South to North Water Diversion Project,and realize the target of transporting a canal of clean water to the North.
