Embodiment Construction

[0029] The present invention will be further elaborated and described below with reference to the accompanying drawings and specific embodiments. The technical features of the various embodiments of the present invention can be combined correspondingly on the premise that there is no conflict with each other.

[0030] The present invention can effectively treat the contaminated soil containing volatile and semi-volatile organic, set the pretreatment process according to the specific conditions of the contaminated soil, and excavate and dry the soil in advance before processing.

[0031] In this embodiment, the box body orientation of the multifunctional repair device is expressed as "up", "down", "left", "right", "front" and "rear". Specifically, refer to figure 1 orientation of the drawing. Among them, the dosing device is located above, the box support is located below, the feeding unit is located at the back, and the discharge port is located at the front. Heating layers...

Abstract

The invention discloses multifunctional remediation main body equipment and an organic contaminated soil remediation device and method thereof, and belongs to the field of environmental protection equipment. The equipment comprises a feeding unit, a repairing unit and an unloading unit, the repairing unit comprises a box body shell, a box body bottom plate and a top cover, and the box body shell, the box body bottom plate and the top cover define a repairing cavity; a bearing bottom plate fixed on the box body shell is arranged above the box body bottom plate, and an air inlet pipe and at least two first bearing bases are supported and fixed on the bearing bottom plate; a hollow shaft is vertically mounted on the first bearing base, and a spiral blade for stirring materials is coaxially fixed on the outer side of the hollow shaft; the dosing device, the hollow shaft and the spiral blade are communicated to form a dosing channel; the unloading unit comprises a hydraulic system and an inclined plate, and the hydraulic system is used for controlling opening and closing of a bottom plate of the box body; when the box body bottom plate is opened downwards, the box body bottom plate and the inclined plate can jointly form a slope enabling materials to slide down. The method can realize in-situ ex-situ remediation of single or composite organic contaminated soil, and has soil remediation and conditioning functions.

Description

technical field [0001] The invention relates to the technical field of contaminated soil treatment and restoration, in particular to a multifunctional restoration main device and a device and method for restoring organic contaminated soil. Background technique [0002] As an important production and environmental factor, soil is one of the natural resources on which human beings and the natural environment depend. With the rapid economic development, frequent industrial activities lead to a large amount of organic pollutants entering the soil environment. Organic pollutants have carcinogenic, teratogenic and mutagenic risks to living organisms, are not easily degraded under natural conditions, and can be transferred and transformed between different media, resulting in high environmental risks. The remediation of organically polluted soil is one of the focuses of current environmental protection work. Organic contaminated soil remediation methods include physical methods (...
