Description

Sewage toxin condition monitoring projection positioning tracing method and system Technical Field The invention relates to a sewage monitoring technology, in particular to a sewage toxin monitoring projection positioning tracing method and system. Background The sewage toxicity monitoring is to evaluate and pre-warn the overall toxicity of a certain area, such as important living communities, chemical enterprises park easy to make toxicity, and the like. Since 2018, regular sewage drug content detection work has been carried out in multiple provinces, and pollution discharge links and life discharge links in the production and manufacturing process are monitored, so that drug spreading is discovered, treated and restrained. And (3) deploying a plurality of sewage sampling points in urban areas, periodically sampling sewage at all the sampling points, sending the sewage to a sewage detection laboratory for drug content detection, judging whether the concentration value of each sampling point exceeds the standard by a worker, and checking tracing according to the list of the sampling points exceeding the standard if the concentration value exceeds the standard. Due to the sewage flow, one-time abnormal discharge can cause abnormal detection results of a plurality of sampling points, the concentration difference is very tiny, and the flow direction of a sewage pipe network is unknown. In a sewage pipe network with vertical grids, workers often unify concentration values of four points around a key area into a group to form a square area, and comprehensively consider the square area to judge whether the square area exceeds standard or not and determine a source. The scheme has the following defects: 1. The tracing efficiency is low, manual statistics and step-by-step calculation are needed, and the support of systematic whole process analysis and calculation is lacked. 2. The calculation method is inaccurate, the content value of each sampling point in normal discharge (due to the reasons of individual medicine taking and the like, the content is slightly less in normal time), the concentration change is unclear, and the result is influenced. 3. The statistical method is not scientific, and the concentration values of four points are directly compared, so that the integral drug content change of the square area cannot be accurately reflected. 4. And (3) lacking an early warning effect, such as building and identifying an electronic early warning fence in the traced key grid area. Disclosure of Invention In order to solve the defects in the prior art, the invention provides a sewage toxin monitoring projection positioning tracing method. The invention aims at realizing the following technical scheme: the sewage toxin condition monitoring projection positioning tracing method comprises the following steps: A1.
