湘江流域污染土壤修復(fù)技術(shù)選擇與優(yōu)化應(yīng)用分析
[Abstract]:With the rapid development of industrialization and urbanization, the discharge of "three wastes" into the environment increases day by day, resulting in severe environmental pollution problems, causing adverse effects, and environmental restoration work needs to be carried out urgently, in which soil pollution presents multi-source and compound type. The pollution characteristics of large quantity, wide area and strong toxicity make the process of soil environment restoration project complicated and arduous. In recent years, soil pollution and soil remediation have aroused widespread concern from all walks of life, and a large amount of funds have been invested in the remediation of pollution. The environmental remediation work in various places has made some progress, with the increasing demand for soil remediation. The research on site restoration project technology selection and site management is of great significance. In this paper, the method of multi-objective decision analysis is applied to the selection of restoration technology, which can synthetically affect the various factors of site restoration, assist in scientific decision making and promote the development of site restoration. The soil pollution in Xiangjiang River Basin is serious, and it is a state-led experimental area for heavy metal pollution remediation. The study on the selection and optimization of soil remediation technology can provide guidance for environmental remediation in this area and even in the whole country. In this paper, the heavy metal pollution control area in Xiangjiang River Basin is taken as the research object. Firstly, the development of soil remediation technology and project decision analysis is reviewed and analyzed, and then the natural resource characteristics and social and economic development of the basin are analyzed. This paper reviews the serious heavy metal pollution in this area and analyzes the main reason for the serious pollution of farmland and sediment in Xiangjiang river basin is the industrial structure dominated by heavy chemical industry. Secondly, this paper tries to combine the analytic hierarchy process (AHP) of multi-objective decision analysis with the method of distance between advantages and disadvantages, and establish the AHP-TOPSIS evaluation model to screen the soil remediation technology suitable for the key area of Xiangjiang river basin. According to the influencing factors of site restoration project and the pollution status of the research area, the preliminary screening of technology, the construction of evaluation index system, and the evaluation index and primary selection technology are evaluated by expert questionnaire survey. Analytic hierarchy process (AHP) is used to deal with the data to determine the index weight, and the final ranking of the primary selection technology is carried out by using the method of distance between advantages and disadvantages, and the evaluation results are obtained. The applicability of the main remediation technology in the key areas of Xiangjiang River Basin is fixed / hidden plant remediation technology soil leaching technology chemical oxidation technology electric remediation technology. Finally, the paper puts forward some reasonable suggestions for the optimal application of fixed / stabilized technology in this area. It is considered that the technology research and innovation can be developed in the direction of environmental friendliness, the cost structure can be optimized and the comprehensive restoration technology can be developed, and so on. To improve the applicability of this technique in the soil remediation of Xiangjiang River Basin.
