[0126] Specifically, a first threshold is set for the average failure time interval of the device, a second threshold is set for the average maintenance time interval of the device, and a third threshold is set for the average error reporting time interval of the device.

[0127] Among them, when the average failure time interval of the equipment is lower than the first threshold, it is considered that the threshold is reached; when the average maintenance time interval of the equipment is higher than the second threshold, it is considered that the threshold is reached; when the average error time interval of the equipment is lower than the third threshold, it is considered that the threshold is reached.

[0128] Furthermore, the risk warning module 16 includes: a sewage treatment risk warning module 32, which performs sewage treatment risk warning according to the arithmetic mean, variance value and root mean square error value of the detection instrument data.

[0129] Specifically, the sewage treatment risk warning module 32 is used to identify whether the arithmetic mean of the detection instrument data is within a preset range. If not, a sewage treatment risk warning is issued; if so, it continues to determine whether the variance value and the root mean square error value of the detection instrument data are both within the preset range. If not, a sewage treatment risk warning is issued.

[0130] Preferably, the risk warning module 16 provided by the present invention can also achieve more accurate sewage treatment risk warning based on normalized data by introducing SVR model, LSTM model, GRU model and LSTM-GRU combination model.
