Embodiment Construction
[0054] The water quality analysis object of the present invention is surface water. Due to the variable sampling locations, the composition of water samples and the content of each component also vary greatly with the different pollution conditions. From the perspective of the analysis object, the interference of suspended solids, colloidal substances and inorganic ions in the water sample to be analyzed will seriously affect the analysis accuracy. However, these interferences cannot be physically separated and removed, and have no clear statistical characteristics. They cannot be removed by ordinary filters. Other effective means must be used to reduce the impact of interference. The existing denoising methods either require more prior knowledge, or the setting of the denoising mechanism is unreasonable, and are not suitable for the research object of water quality spectral analysis; and the feature extraction method is not specially designed for signal denoising, and cannot ...
