Early warning method, device and system for water quality monitoring and computer readable storage medium

The embodiment of the invention provides an early warning method for water quality monitoring. The early warning method comprises the following steps: acquiring concentration information of a plurality of correlation factors in water quality monitoring parameters; the concentration information of the multiple correlation factors is calculated according to different preset concentration mean value algorithms to obtain respective corresponding calculation results, the respective corresponding calculation results are comprehensively compared with a water quality sudden change rule, and the current early warning level is determined; and sending corresponding early warning information according to the current early warning level. Automatic early warning is carried out on water quality monitoring based on concentration information of a plurality of correlation factors and a water quality sudden change rule, and early warning information of a corresponding grade can be timely sent out according to different change c
