The invention discloses a method and equipment for tracing the source of water pollution based on topological correlation. A plurality of water quality monitoring stations are set along a river basin, and correlation analysis and topological analysis are performed on each water quality monitoring station to trace the source of water pollution. The specific method is as follows: firstly, based on the spatial distribution of water quality monitoring stations, the topological analysis of the water quality monitoring stations is carried out to obtain the topological structure between the water quality monitoring stations; and based on the historical data, the association analysis of the water quality monitoring stations is carried out to obtain the relationship between the water quality monitoring stations. Correlation degree; then combined with the correlation degree and topological relationship between 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 can effectively trace back to the pollution point, and has better accuracy, and can be actually applied to the development of embedded equipment and the environmental 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 ...
