Tap water detection method and system and storage medium

The invention discloses a tap water detection method and system and a storage medium, and the method comprises the steps: obtaining current turbidity data, pH data, water temperature data and dissolved oxygen concentration data, and inputting the data into a standard water quality detection model to obtain a water quality detection score value; when it is judged that the water quality detection score value is smaller than a preset score threshold value, an alarm instruction is generated and sent to the control end, so that the control end closes the corresponding abnormal water source according to the alarm instruction; the standard water quality detection model training process comprises the following steps: acquiring historical turbidity data, pH data, water temperature data and dissolved oxygen concentration data, and carrying out data preprocessing and PCA dimension reduction operation to obtain dimension reduction data; and on the basis of taking the dimension reduction data and preset standard water qua
