Nearly, production pollution due to human economic activity increased, resultingin many parts of the world soil pollution area is expanding. And it has affected the soilecological structural and stability. At present, the industry moved from the city center,the factory covers an area of most of the pollution, make it inappropriate for vegetationgrowth on the surface, at the same time is bad for humans to construction. For refiningand oil factory, because the oil leakage serious pollution on the ground, it is difficult todeal with. The leaking during transport industrial raw materials, may contain corrosiveacid or alkaline substances, can cause pollution of soil. The pollution of the soil will bea certain influence on the crops and groundwater around.It directly results in thedecrease of grain yield and quality decline, even endanger human body health. With thedeepening of human understanding of importance of soil, soil research is highlyattention, also gradually became a hot issue of environmental science.Research and development process of soil pollution and repair equipment simulationsystem main purpose: First, the simulation of different pollutants under different soiltypes of three-dimensional proliferation, migration and transformation; Second, soilrepair mechanism and repair methods can be used to remove different kinds of pollutionin the soil; Third, it can realize monitoring function such as pressure, temperature,humidity, PH, ORP, salt, etc. And volatile components of collection and the monitoringfunction.This paper analyzes the soil pollution at home and abroad and based on the studyof the repair and related equipment, It fitting the simulated soil pollution and fix twotechnological process. This paper also simulated device enclosure, heating element,simulate saturated soil water flow rate of water seepage device, adjusting device ofoxygen content in the box body, and the structure design of the soil sampling device. Atthe same the paper is to design and realize the temperature control inside the equipmentfor monitoring soil parameters inside the equipment selection and arrangement of instrument. This paper in order to realize automatic extraction and liquid pollutants onsoil samples/repair agent automatic injection, preliminary finished three coordinates, thedesign of traveling mechanism.Soil repair equipment in our country, mainly on a large scale, assist to small. Theequipment for Simulation of soil pollution and Simulation of soil restoration is fewreport. It is very little for applied to the experimental equipment. The research of thispaper fills the blank of this field in domestic. This equipment can be in indoor simulatednatural environment under the condition of atmosphere, soil pollution mechanism,regularity and repair methods of research. It can be for soil pollution and repair theresearchers provide a practical platform. It the study of soil repair equipment has verygood reference and guidance, and it has good practical significance.
