Problems solved by technology

The infrastructure construction period of the disposal site is long and the cost is high, which is not suitable for small and medium-sized projects
After the contaminated soil is treated, the structure needs to be demolished, which is time-consuming, laborious and costly
Moreover, during the process of off-site disposal, the dust containing chromium pollution is easy to escape into the atmosphere, causing air pollution

Abstract

The invention relates to a dump leaching remediation system for chromium contaminated soil. The dump leaching remediation system comprises a buried shell, the buried shell is buried under the ground;a storage part is placed in the buried shell, a chromium contaminated soil dump is stored in the storage part, the buried shell is further filled with remedied soil, the outer surface of the storage part is connected with a spraying pipe, the spraying pipe sprays remediation liquid into the storage part, and a circulation opening is formed in the outer surface of the buried shell. A built-in supporting plate is fixedly connected to the interior of the buried shell, a placement opening is formed in the built-in supporting plate, and the storage part is placed in the placement opening. The dumpleaching remediation system is simple in structure, convenient to operate and flexible to use, the whole system device can be recycled, the soil outside the externally-hidden pipe is independently treated, detection is facilitated, the external soil is replaced according to the remediation process, the remediation efficiency is improved, and application and popularization are facilitated.

Description

technical field [0001] The invention belongs to the technical field of soil restoration, and in particular relates to a heap leaching restoration system for chromium-contaminated soil. Background technique [0002] At present, chromium-contaminated soil remediation mostly adopts ex-situ remediation. In the past remediation process, most projects were to excavate and transfer the contaminated soil to specific structures for treatment. The structure is generally a concrete structure, which needs to occupy a large site space. The infrastructure construction period of the disposal site is long and the cost is high, and this kind of disposal method is not suitable for small and medium-sized projects. After the contaminated soil is treated, the structures need to be dismantled, which is time-consuming, laborious and costly. Moreover, during the process of off-site disposal, the dust containing chromium pollution is easy to escape into the atmosphere, causing air pollution. The...
