Abstract

The invention discloses a pretreatment device and a soil in-situ remediation system, relates to the technical field of soil remediation and is designed for solving the problems of secondary pollutionand non-ideal remediation effect in the existing soil remediation process. The pretreatment device comprises a closed chamber, a crushing and screening device which is arranged in the closed chamber and a waste gas treatment device; the crushing and screening device is fixedly provided with a first blower; and the waste gas treatment device is used for treating gas in the closed chamber and exhausting the gas out of the closed chamber. The soil in-situ remediation system comprises the pretreatment device, a conveying device, a stirring device and a medicament storage device which provides a medicament for remediating soils into the stirring device, wherein the conveying device, the stirring device and the medicament storage device are arranged in the closed chamber. The pretreatment deviceand the soil system thereof provided by the invention are used for remediating the soils and exhausting the waste gas produced in the remediating process after treating the waste gas.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a pretreatment device and an in-situ soil remediation system. Background technique [0002] Today's industrialization process is accelerating, and the application of chemical fertilizers and pesticides has caused serious soil pollution. Although the soil itself has a certain purification ability, when the amount of pesticides entering the soil exceeds the environmental capacity of the soil, soil pollution will be formed, which will have a serious impact on the soil ecosystem. At the same time, it will also enter the human body through the food chain, causing serious damage to human health. harm. [0003] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil, reducing its concentration to an acceptable level, or converting toxic and harmful pollutants into harmless substances. ...
