Abstract
The invention provides a reservoir water quality predicating system and a method thereof. The system comprises the components of a water quality monitoring device which monitors water quality index monitoring data and algae growth characteristic data of a monitoring point; a water quality predicating device which receives the water quality index monitoring data and the algae growth characteristicdata, performs analysis on the water quality index monitoring data and the algae growth characteristic data, obtains a reservoir water quality predicating model and performs predication on the water quality of a to-be-predicated reservoir according to the water quality index monitoring data, the algae growth characteristic data and the reservoir water quality predicating model, thereby obtaining predicating data; an early-warning grading device which receives the predicating data, determines a target early-warning grade according to the predicating data, and displays the target early-warning grade. The reservoir water quality predicating system can predicate the water quality of the to-be-predicated reservoir and can perform early warning before an algal booming event, thereby reminding related personnel of taking a countermeasure in advance, facilitating reservoir water quality management, and settling a technical problem of hysteresis in reservoir detection.
Description
technical field [0001] The invention relates to the technical field of water pollution control, in particular to a reservoir water quality prediction system and method. Background technique [0002] Nowadays, lakes and reservoirs have become an important water source for cities, and the water quality safety of reservoirs directly affects the health of urban residents and the development of urban economy. However, with the further intensification of non-point source pollution, the pollutants entering the reservoir have increased sharply, making the water quality of many lakes and reservoirs continue to deteriorate, and water quality safety cannot be guaranteed. At the same time, reservoir pollution sources are complex and diverse, and after pollutants enter the water body, they will migrate and transform with the flow of water. Due to the large volume of the reservoir, the water quality elements of the water body are different in spatial distribution, and due to the hydrologi...
