Embodiment

[0065] Step 1. Determine the rare earth mine area that needs soft measurement, and collect groundwater samples in the determined area for ZN=58 consecutive days, and test the collected groundwater samples. Water quality indicators: nitrite nitrogen, nitrate nitrogen, total phosphorus , ammonia nitrogen, water temperature, pH value, dissolved oxygen, and total nitrogen, the collected groundwater quality index data is used as a sample data set; % is set as the training data set of the support vector machine, and the last 30% is set as the test data set;

[0066] Step 2, the user initializes the parameters, and the initialization parameters include soft measurement span days FD=2, population size Popsize=50, neighborhood radius NK=5, maximum unimproved times Limit=100, and maximum evaluation times MAX_FEs=400000;

[0067] Step 3, make the current evolution algebra t=0, the number of optimal design parameters of the support vector machine D=3, and make the current evaluation times...

Abstract

The invention discloses an artificial bee colony optimized rare-earth mine underground water total nitrogen concentration soft measurement method which adopts a support vector machine as a soft measurement model for total nitrogen concentration of underground water of a rare-earth mine, and a penalty factor C and a radial basis kernel parameter g of the support vector machine and a parameter epsilon are optimized and designed by using an adaptive artificial bee colony algorithm. In the adaptive artificial bee colony algorithm, search zoom factors are adaptively adjusted by using feedback information of an adaptive value, and information of an optimal individual of an adjacent domain and an optimal individual of a global domain is infused to a Gaussian variation strategy to generate new individuals adaptively. By adopting the method, the soft measurement precision of the total nitrogen concentration of the underground of the rare-earth mine can be improved.

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...
