The invention provides intelligent normal-temperature desorption remediation equipment and method for volatile organic contaminated soil. According to the invention, an intelligent precise dosing system intelligently adds a soil conditioner into the soil, the soil moisture content is effectively reduced, and the soil properties are improved; an efficient turning and throwing system is used for turning and throwing soil in a targeted manner according to soil properties or a remediation stage; a hot air system blows hot air into the contaminated soil to promote desorption of pollutants in the soil; an intelligent monitoring platform calculates the adding amount of the soil conditioner and the spraying frequency of the soil conditioner according to the soil moisture content detection result;the intelligent monitoring platform calculates the type, the spacing, the group number, the turning and throwing frequency and time of the gears to be turned and thrown according to the soil property;the intelligent monitoring platform calculates the required heating wind speed, temperature and time according to the pollutant PID value; and the intelligent monitoring platform carries out autonomous training and learning to form optimal control parameters for volatile organic pollutants, and related optimal control parameters can be directly called in subsequent work.
Description
technical field [0001] The invention relates to the technical field of soil remediation, in particular to an intelligent, high-efficiency normal temperature desorption repair equipment and method for volatile organic polluted soil. Background technique [0002] Pesticide factories, coking plants, petroleum processing plants and other industrial factories are producing more and more organic pollution to the soil because of the volatile organic compounds in their products. With the change of urban development plan, the factory moved to a new site, and it is urgent to control the soil pollution in the decommissioned factory area to meet the new development plan. At present, normal temperature desorption technology is often used to remediate soil polluted by volatile organic compounds. The repair effect of normal temperature desorption technology is easily affected by the external environment (temperature and humidity, air flow rate, etc.), soil properties (texture, moisture co...
