The invention belongs to the technical field of
pollution source detection, and discloses a
pollution source detection method and
system for
water environment treatment. Comprising the steps that acoustic disturbance data are collected through an
underwater acoustic sensor, real-time edge preprocessing is carried out,
water environment data of different depths are synchronously collected,
water environment gradient data are calculated, and then
data synchronization is achieved through a unified
timestamp.
Fourier transform is adopted to extract
frequency domain characteristics of the sound disturbance signals, the main frequency, the energy difference and the
frequency spectrum skewness are calculated, and disturbance
sound wave indexes are generated according to the main frequency, the energy difference and the
frequency spectrum skewness. In combination with disturbance
sound wave indexes and
water body environment gradient data, a sliding window is adopted to construct a
time sequence sample set, a
recurrent neural network model for predicting future
pollution release risks is trained, differentiated pollution release threshold values are set according to different
water body types, and when model output exceeds the threshold values,
sediment pollution early warning instructions of corresponding levels are automatically generated. And efficient and graded pollution event intelligent identification and response are realized.
