Problems solved by technology

[0005] The purpose of the present invention is to provide a method and system for online dynamic tracking and monitoring of water pollution sources, which solves the problem that the frequency of online monitoring is automatically changed with the change of the flow rate of discharged industrial wastewater and / or the change of pollution concentration, so as to achieve monitoring in line with the actual state of sewage discharge technical issues

Embodiment Construction

[0019] The monitoring method of the present invention includes automatically and regularly starting the online monitoring instrument for analysis and determination and the fixed time interval control monitoring of sample retention at a specified time interval when the minimum flow condition is reached. In addition to this existing common monitoring method, the present invention The online dynamic tracking monitoring method for water pollution sources also has the function of effective monitoring as the enterprise's wastewater discharge volume increases abnormally and wastewater parameter indicators exceed the standard. The monitoring method of the present invention sets a minimum flow value a according to the actual situation of the production nature and scale of each enterprise (ie water pollution source), and also sets a flow mutation base value b and a large flow value e. When the monitoring system When the flow in the middle weir trough reaches the lowest flow value a, the f...

Abstract

This invention is about measurement. It is a method of on-line moving trail monitor towards water pollution source including the analytical determination and keeping sample via on-line monitoring device following the regulated space of time under minimum flow. It also sets the mutant basis and a multiple flow rates among which the on-line monitoring device starts to detect when the flow rate is C(1+N%), the C is the flow rate of the previous mutant rate, N is positive number that is less than 100. The on-line monitoring device will come into special time-control monitoring according to the set time-space of different enterprises when the flow rate more than or equal the maximum amount. If the index of over proof pollution is caught, the over-proof time control monitoring will start and keep the sample when the parameter of the latter monitor outnumbers the former. It settles the automatic change of the monitoring frequency according to the change of the amount of the trade waste and the pollution concentration so as to agree with the technology of the virtual condition of the monitoring pollution.

Description

Technical field: [0001] The present invention relates to measurement, in particular to a method and system for online dynamic tracking and monitoring of water pollution sources. Background technique: [0002] Water is one of the important resources that life on the earth depends on for survival, but with the development of human material civilization, rivers, seas, rivers, and lakes are constantly being polluted, and pure water resources are increasingly depleted. Due to water pollution, it not only directly endangers human beings, but also seriously disturbs the natural ecological environment. For this reason, the problem of water pollution is being paid more and more attention by governments of various countries, and corresponding regulations and measures have been formulated, and a lot of funds have been invested to protect water sources. Since the 1980s, my country has successively established automatic water quality monitoring stations in key industrial cities to measure an...
