Pollution discharge enterprise monitoring method based on power consumption data distribution

Abstract

The invention discloses a pollution discharge enterprise monitoring method based on power consumption data distribution. The pollution discharge enterprise monitoring method comprises the following steps: screening pollution discharge enterprises to be monitored: obtaining daily power consumption data of the pollution discharge enterprises to be monitored in an observation time period, and an average value and a standard deviation of the power consumption data; setting a first interval by adopting a normal distribution 3 sigma principle, and screening a first suspected abnormal pollution discharge enterprise list; grouping all the to-be-monitored pollution discharge enterprises according to industries, and calculating the average value and the standard deviation of the current-day power consumption data of each group of enterprises day by day; setting a second interval by adopting a normal distribution 3 sigma principle, and screening a second suspected abnormal pollution discharge enterprise list; and carrying out cross validation on the first suspected abnormal pollution discharge enterprise list and the second suspected abnormal pollution discharge enterprise list to obtain a final suspected abnormal pollution discharge enterprise list. According to the invention, pollution discharge enterprise monitoring is realized based on double intervals and multiple thresholds by using the power consumption data, and the pollution discharge condition of the enterprises can be reflected more objectively.

Description

technical field [0001] The invention belongs to the technical field of enterprise sewage discharge status monitoring, and relates to a sewage discharge enterprise monitoring method based on electricity consumption data distribution. Background technique [0002] Monitoring of polluting enterprises is a very important task for environmental governance. At present, the monitoring methods for the sewage discharge of enterprises can be classified into two categories: civil air defense and technical air defense. [0003] Civil air defense mainly conducts regular inspections and supervision by the environmental department, or conducts investigations by accepting social reporting clues; on the one hand, this method makes the workload of the environmental department larger, and on the other hand, the discovery of abnormal sewage discharge has a certain degree of chance. [0004] Technical prevention mainly introduces sensors that can monitor in real time to sewage equipment or sewa...

AI Technical Summary

Problems solved by technology

This kind of technical defense method requires additional equipment to establish a system, which requires enterprises or the government to bear additional costs, which increases the cost of monitoring.

[0005] In addition, in the process of technical defense and civil air defense, there are still hidden abnormal sewage discharge behaviors, and sewage discharge enterprises can conduct sneak discharge by bypassing monitoring equipment, and the feedback data is inaccurate

[0006] To sum up, there are usually shortcomings in the existing enterprise sewage monitoring technology, such as high labor cost, heavy burden on enterprises, and distortion of monitoring data.
