Problems solved by technology

Many domestic researchers have done a lot of research on the underlying surface of different river basins, but there are very few studies on heavy metal pollution, and there is almost no prediction of heavy metal pollution load at the soil-water interface of heavy gold mines.

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and experimental examples.

[0028] In this example, the Hongqi mining area of ​​Hunan Xiangtan Manganese Mine is used as the experimental area, and the prediction model of the heavy metal manganese pollution load in the heavy metal pollution flow at the soil-water interface of the mining area is verified. The concrete steps of this embodiment are as follows:

[0029] (1) Sample collection and pretreatment:

[0030] The 2.6 square kilometers mining area of ​​Hongqi Mining Area of ​​Xiangtan Manganese Mine in Hunan Province is taken as the research area. According to the requirements of the principle of representativeness, uniformity and typicality, the sampling points of the sampling plan are arranged. The collection of water samples adopts the systematic random distribution method, and the sampling points are evenly distributed in the research area and GPS is...

Abstract

The invention discloses a metal-mining-area soil-water interface heavy metal pollution load forecasting method. The metal-mining-area soil-water interface heavy metal pollution load forecasting method mainly comprises the following steps of sample collection and pre-processing, sample detection, data processing, building of a GIS database, building of a metal-mining-area soil-water interface heavy metal migration and transformation kinetic model, and building, verification and optimization of a forecasting model method. The fitting degree of the forecasting method with a measured value of an actual load can meet the requirement for forecasting precision, and therefore theoretical foundations and scientific bases are provided for evaluation, controlling, treatment, restoration and the like of ecological risks of metal-mining-area heavy metal pollution.

Description

technical field [0001] The invention belongs to the technical field of environmental pollution evaluation and control of metal mines, and in particular relates to a method for predicting heavy metal pollution loads at soil-water interfaces in metal mine areas. Background technique [0002] Soil-water interface pollution flow is a composite pollution fluid produced by polluted soil under the action of rainfall or snowmelt runoff. The pollutants include various heavy metals, persistent organic matter, nitrogen, phosphorus and other nutrients, and are also non-point source pollution. A special form of expression. [0003] Heavy metals (such as Mn, Pb, Cd, Cr, Cu, Zn, etc.) are global environmental pollutants, all of which are chronically toxic and carcinogenic to humans and organisms. With the extensive use of various metals (such as iron, antimony, copper, manganese, lead, zinc, manganese, etc.) Under the action, the heavy metal pollution flow at the soil-water interface in ...
