Abstract

The invention relates to a contaminated soil remediation technology, and solves the problem of low treatment efficiency of thermal desorption equipment caused by high water content in contaminated soil. The invention discloses the contaminated soil treatment equipment which comprises a treatment equipment shell and a soil sample car which can go in or out of the shell, wherein hot air conveying pipelines are arranged in the shell and the soil sample car, and the contaminated soil is heated and blown by high-temperature heat; and the shell is connected with the soil sample car through a pulley-sliding rail mechanism, and a hydraulic stay rod capable of overturning the soil sample car is arranged at the outer side of the shell. The soil pre-treated by the equipment enters the thermal desorption equipment, so that the energy consumption of baking the soil can be saved, the effective residence time can also be increased, and the remediation efficiency is improved. By using the equipment, the remediation speed of the soil can be greatly improved, the energy consumption of remediation can be effectively reduced, the cost is saved, the operation is simple, and the practicality is strong.

Description

technical field [0001] The invention belongs to the technical field of contaminated soil remediation, in particular to industrial contaminated soil processing equipment. Background technique [0002] In the remediation of contaminated sites, thermal desorption and desorption technology is generally used for contaminated soil with high concentrations of organic matter. However, at present, this kind of equipment directly enters the equipment for treatment. The energy consumption in the treatment process is greatly increased, and the effective residence time is insufficient, which reduces the treatment efficiency of the thermal desorption and desorption equipment. Contents of the invention [0003] The purpose of the present invention is to solve the problem of reduced treatment efficiency of thermal desorption equipment caused by high water content in polluted soil, and provide a polluted soil treatment equipment for pretreatment of pollution before thermal desorption and d...
