Water quality evaluation method for real-time early warning of water supply network

The invention discloses a water quality evaluation method for real-time early warning of a water supply network, and belongs to water supply network water quality evaluation methods. According to the water quality evaluation method, water quality of the water supply network is evaluated systematically according to two indexes, including residual chlorine and turbidity, in real-time water quality monitoring data of the water supply network on the basis of water quality classification, and accordingly, water quality control and water pollution early warning of the water supply network are achieved. The water quality evaluation method includes 1, classifying the water quality of the water supply network, and creating a fuzzy set of water quality parameters; 2, determining the membership degree of the water quality parameters to acquire an evaluation matrix; 3, calculating entropy values of the evaluation indexes; 4, calculating entropy weight values of the evaluation indexes; 5, performing comprehensive evaluation on the water quality of the water supply network. The water quality evaluation method has the advantages that the implementation scheme of the water quality evaluation method is systematic and orderly, water quality conditions of different water quality motoring points of a water supply network system can be evaluated rapidly and effectively, water quality evaluation for real-time early warning of the water supply network is achieved, and the water quality evaluation method can be applied to water supply network systems of different regions and cities of China.
