Remote online water quality monitoring method based on curve fitting and toxicological analytical algorithm

Abstract

The invention provides a remote online water quality monitoring method based on a curve fitting and toxicological analytical algorithm. The method comprises the following steps: a water quality comprehensive biological toxicity analyzer is used for monitoring inhibition degree of toxic substances in sampling liquid on luminescence intensity of bioluminescent bacilli; luminescence intensity information is sent to a remote server; data processing of the luminescence intensity information is carried out by the server in order to determine class of pollution of sewage toxicity; and result information is searched on a remote client. Compared with the prior art, the improved curve fitting algorithm is implanted, a Fabonacci method is used for further optimizing each coefficient of an improved curve fitting model, in order to realize prediction of components and concentrations of toxic substances; at the same time, the effects of magnetic stirring time, culture temperature, culture time, exposure duration, and pH value range on the result measured value are also considered, the influences of each condition on biological toxicity tests of luminescent bacteria are analyzed, so that measurement precision and stability of the analyzer are improved, and remote online monitoring is realized.

Description

technical field [0001] The invention relates to the technical field of online water quality monitoring, in particular to a remote online water quality monitoring method based on curve fitting and toxicological analysis algorithms. Background technique [0002] With the development of modern science and technology, multi-component simultaneous detection and intelligent water quality sensors are currently a hot research direction for online water quality analysis and detection. The technology is becoming more and more mature and has gradually entered the application stage. Since the 1970s to the early 1980s, foreign scientists have successfully isolated luminescent bacteria that are harmless to the human body and sensitive to toxic chemicals from marine organisms, and used them to detect the comprehensive toxicity of water bodies. Now this simple and rapid water comprehensive toxicity detection technology has been widely used. In some foreign countries and regions, the techno...

However, these methods all use the minimum idea of ​​the longitudinal distance that the actual value deviates from the local similarity curve. Therefore, it essentially guarantees that the local similarity curve is "similar in value" rather than "similar in shape" to the points before the prediction time. The prediction accuracy of these methods is not high at the inflection point, and similar methods are currently widely used in weather forecasting operations, which can achieve very good prediction functions
