Riverway sewage draining exit tracing method based on gridding water quality monitoring

Abstract

The invention relates to a riverway sewage draining exit tracing method based on gridding water quality monitoring, which comprises the following steps of dividing a river into a plurality of river reaches, carrying out gridding water quality monitoring on each river reach, and obtaining monitoring data of each river reach, according to the monitoring data of each river reach, acquiring the discharge water quantity of the sewage draining exit of each river reach, and achieiving quantitative accounting of the pollutant discharge amount, and obtaining the river reach with sewage discharge according to the quantitative accounting result, encrypting the gridding water quality monitoring of the river reach with sewage discharge, and gradually narrowing the troubleshooting range to realize the source tracing of the riverway sewage draining exit. Compared with the prior art, the method solves the problem that on-site troubleshooting is difficult due to pollution discharge amount accounting, underwater discharge and the like of the sewage draining exit, and provides a relatively convenient traceability troubleshooting means for the riverway sewage draining exit.

Description

technical field [0001] The invention relates to the field of traceability of river sewage discharge, in particular to a method for traceability of river sewage outlets based on gridded water quality monitoring. Background technique [0002] The investigation and remediation of river sewage outlets is the basic work of water environment governance. At present, although the statistical sewage collection rate in my country's urbanized areas has reached an average of more than 90%, but according to the calculation of the pollution load collection rate, the average is only 60%, indicating that a large number of pollutants still enter the river. The sewage outlets entering the river are the last "gate" for pollutants to enter the river. Only by fully understanding the number of sewage outlets entering the river and the amount of pollutants discharged can we effectively improve the pollutant collection capacity and promote the fundamental improvement of the water environment qualit...

AI Technical Summary

Problems solved by technology

[0003] The situation of sewage outlets in rivers is complicated. Under the current situation that the investigation of sewage outlets above the water surface has achieved remarkable results, the current difficulty is the investigation of underwater sewage outlets and the calculation of pollutant discharge volume.

It is difficult to identify hidden underwater sewage outlets by relying on traditional methods such as manual inspection on foot and aerial survey by UAV; Difficult to implement and other issues, so it is difficult to conduct round-the-clock surveys, and it is impossible to quantitatively calculate the amount of sewage and pollutant discharge
