The invention discloses a water pollution traceability method and a water pollution traceability device based on topological association. The water pollution traceability is carried out by setting a plurality of water quality monitoring stations along a river basin and carrying out correlation analysis and topological analysis on each water quality monitoring station. Firstly, based on the spatialdistribution of water quality monitoring stations, the topology of water quality monitoring stations is analyzed, and the topology structure between water quality monitoring stations is obtained. Based on the historical data, the correlation degree of water quality monitoring stations is obtained by correlation analysis. Then combining with the correlation degree and topological relationship between the water quality monitoring stations, the traceability analysis of the alarm stations is carried out, and the possible traceability points and their probabilities are obtained. The invention canbe effectively traced back to the pollution point, and has good accuracy, and can be practically applied to the development of embedded equipment and the environment protection big data platform.
Description
technical field [0001] The invention relates to a method and equipment for tracing the source of water pollution based on topological correlation, and belongs to the technical field of water environment monitoring. Background technique [0002] Due to the complexity of the watershed environment, it is difficult to accurately trace the source of water pollution. Therefore, the method of water pollution traceability based on probability is a commonly used method. According to the traceability method, multiple possible pollution sources are obtained, and the probability of them as pollution sources is calculated. Literature [1] (Wang Jiabiao, Lei Xiaohui, Liao Weihong, et al. Traceability of sudden water pollution in rivers and canals based on coupling probability density method [J]. Journal of Hydraulic Science, 2015, 46(11): 1280-1289) proposed a Based on the coupling probability density method, the method of tracing the source of sudden water pollution in rivers and canals ...
