Taking the tunnel sewage of a railway project as an example,through comprehensively analyzing the change law of SS and pH value online monitoring data,an early warning threshold judgment method based on frequency analysis method was established.Based on this method,combined with the early warning duration,an online monitoring and early warning system for tunnel construction wastewater was also constructed.Through real-time monitoring and timely classification early warning,the abnormal situation of sewage discharge can be found in time to avoid the discharge of sewage that is not up to the standard,which provides technical support for the dynamic management of railway tunnel construction wastewater.
