Chemical oxygen demand (COD) electrochemical rapid online monitoring system

Abstract

The invention discloses a COD (chemical oxygen demand) electrochemical rapid online monitoring system, and particularly relates to the technical field of COD detection. The COD electrochemical rapid online monitoring system is provided with a plurality of sampling modules, a position information integration module, a networking module, a judgment module and an alarm module. The judgment module can judge whether the COD data is abnormal or not by combining the change of the detection data, obtained by the data analysis module, of each monitoring point at different time points, the change of the detection data, obtained by the data analysis module, of the multiple monitoring points at the same time and historical detection data logs in a database, and meanwhile, the networking module collects weather information of an area where data abnormity occurs, judges whether data abnormity changes are caused by raining or not, and can judge an approximate monitoring area where the data abnormity occurs according to the position information of all the monitoring points and a layout diagram of all the monitoring points, so that accurate judgment of the data abnormity situation is guaranteed, the probability of false alarm due to rainy weather is reduced to a certain extent, an abnormal area with an abnormal condition can be quickly and accurately judged, and an accurate position can be timely found out for checking and overhauling.

Description

technical field [0001] The invention relates to the technical field of COD detection, more specifically, the invention relates to a COD electrochemical rapid on-line monitoring system. Background technique [0002] Chemical oxygen demand (COD) is a chemical method to measure the amount of reducing substances that need to be oxidized in a water sample. The oxygen equivalent of substances (generally organic matter) that can be oxidized by strong oxidants in wastewater, wastewater treatment plant effluent and polluted water. In the study of river pollution and the nature of industrial wastewater and the operation and management of wastewater treatment plants, it is an important and quickly measured organic pollution parameter, often expressed by the symbol COD. [0003] A high COD means that the water contains a lot of reducing substances, mainly organic pollutants. The higher the chemical oxygen demand, the more serious the organic matter pollution of the river water. The so...

Problems solved by technology

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a COD electrochemical rapid online monitoring system. The technical problem to be solved by the present invention is: the distance setting between a large number of existing monitoring points is unreasonable, and there may be waste of resources or The monitoring efficiency is not ideal. At the same time, most of the monitoring points are operated independently. The staff of the monitoring point is relied on to judge whether the detection data is abnormal. When the data is abnormal, it still takes a lot of time to screen the abnormal position.
