Problems solved by technology

[0003] However, the heat transfer efficiency of the thermal desorption and grasping devices for soil treatment in the prior art is relatively low, making it difficult to completely remove the persistent organic pollutants in the soil, which affects the later use of the soil; on the other hand, the lack of thermal desorption process The treatment of volatile organic gases generated in the process, direct discharge is likely to cause air pollution

Abstract

The invention discloses an integrated device for persistent organic contaminated soil remediation treatment. The device comprises a soil pretreatment device, a soil thermal desorption device, a fixing plate, a bacteria solution delivery device and an electric control box; the soil pretreatment device is arranged at the upper end of the fixing plate, the soil pretreatment device is used for performing crushing and impurity removing on soil, late thermal desorption treatment is facilitated, the soil thermal desorption device is arranged at the lower end of the fixing plate and used for performing thermal desorption treatment on persistent organic pollutants, the organic pollutants in the soil are volatilized, and finally treatment is conducted through a flue gas combustion cylinder, and the bacteria solution delivery device is used for adding the composite bacteria solution into the treated soil, and the electric control box is used for controlling operation of the device. The device is reasonable in structural design, high in treatment efficiency, small in secondary pollution and suitable for mass promotion.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to an integrated device for remediation treatment of persistent organic polluted soil. Background technique [0002] Persistent organic pollutants (POPs) refer to long-distance migration through various environmental media (atmosphere, water, organisms, etc.) Natural or synthetic organic pollutants that pose serious hazards to human health and the environment, mainly including organochlorine pesticides, polychlorinated biphenyls, and dioxins. With the gradual public awareness of the environmental and health hazards of organic pollutants, there is an urgent need for economical and effective methods to deal with these toxic substances. The main remediation technologies for organic pollutant-contaminated soil include biological remediation, chemical remediation, physical remediation, etc. Among many physical remediation or chemical remediation technologies, thermal desorption...
