Disclosed are a total phosphorus measurement method and system for a high-turbidity sample, an automatic water quality monitoring station, a device, and a storage medium. According to the total phosphorus measurement method for the high-turbidity sample in the present invention, an entire measurement process is automated and intelligent, particularly, determination of a relative stable time point of a total phosphorus content in the high-turbidity sample does not need artificial intervention, but is calculated on the basis of a preset algorithm and a historical turbidity-standing time curve, such that the determination accuracy is high; moreover, the measured total phosphorus content result is close to the measurement result of a pre-processing mode in the existing specifications, such that the technical requirements of the existing specifications can be well met, and the invention has wide promotion significance in the application to the automatic water quality monitoring station.
