Description
Technical field: [0001] The invention relates to a contaminated soil remediation device, in particular to a fluidized bed thermal desorption device. Background technique: [0002] With the development of society, technology and economy, people's living standards and health levels are constantly improving, which puts forward higher requirements for the realization of a green environment, and the control of environmental pollution has become an important issue in urban construction. With the adjustment of the industrial structure, many industrial enterprises in the main urban areas of many cities have closed down or relocated, leaving behind a large amount of highly polluted soil, including a large amount of organic polluted soil, which will pollute the surrounding air and water, causing adverse effects on people's life and health. These polluted sites must undergo soil remediation before they can be put into new uses. Therefore, remediation and treatment of polluted soil has ...
