Abstract

The invention discloses a soft measurement method for total nitrogen concentration in underground water in rare earth mining areas optimized by artificial bee colony. The present invention adopts the support vector machine as the soft sensor model of the total nitrogen concentration in the groundwater of the rare earth mining area, and utilizes the adaptive artificial bee colony algorithm to optimize and design the penalty factor C, the radial basis kernel parameter g and the parameter ฮต in the insensitive loss function of the support vector machine . In the adaptive artificial bee colony algorithm, the feedback information of the fitness value is used to adaptively adjust the search scaling factor, and the information of the neighborhood optimal individual and the global optimal individual is fused into the Gaussian mutation strategy to adaptively generate new individuals . The invention can improve the soft measurement accuracy of the total nitrogen concentration in the underground water of the rare earth mining area.

Description

technical field

[0001] The invention relates to the field of measurement of total nitrogen concentration in groundwater, in particular to a soft measurement method for total nitrogen concentration in groundwater in rare earth mining areas optimized by artificial bee colony. Background technique

[0002] The southern region of my country is rich in ionic heavy rare earth resources, and heavy rare earths are indispensable raw materials in modern industrial production. At present, the mining of ionic rare earth resources generally uses the in-situ leaching process. The process is to drill some liquid injection holes on the ionic rare earth mine, and then inject the chemical solution into the mine through the liquid injection holes. However, during the mining of ionic heavy rare earth resources, these chemical solutions injected into the mine will gradually seep into the ground, causing groundwater pollution. The pollution control of groundwater in ion-type rare earth mining a...
