Abstract

The invention relates to the technical field of soil remediation, in particular to a vehicle-mounted skid-mounted soil leaching system, which comprises a milling tunneling device arranged at the frontend of a frame chassis. A crushing device communicated with the milling tunneling device is arranged in a container body; the crushing device is arranged corresponding to the middle stock bin, the middle stock bin is communicated with a negative-pressure air inducing device, the other side of the negative-pressure air inducing device is communicated with a multi-stage rotary leaching device, andthe multi-stage rotary leaching device separates mud and pumps the mud into the centrifugal spin-drying device; tail pulp screened by the multi-stage rotary leaching device enters a purification treatment device; an outlet of the purification treatment device is communicated with slurry of a horizontal cake pressing device, and the horizontal cake pressing device is communicated with a feeding hole of the low-temperature carbonization furnace; a discharge hole of the low-temperature carbonization furnace is communicated with a discharge pipe arranged at the tail part of the container body. Thesystem is reasonable and novel in design and high in automation degree, collection and harmless treatment of contaminated soil and in-situ backfilling of most contaminated soil are achieved, and theadaptability and treatment efficiency of the device are greatly improved.

Description

technical field

[0001] The invention relates to the technical field of soil restoration, in particular to a vehicle-mounted skid-mounted soil washing system. Background technique

[0002] With the continuous acceleration of urbanization and industrialization, the overall situation of soil pollution in my country is grim. There are many reasons for soil pollution, such as industrial sludge, domestic garbage, sewage irrigation, pollutant deposition in the atmosphere, and extensive use of chemical fertilizers and pesticides containing heavy metals. According to preliminary statistics, nearly one-fifth of the existing cultivated land in the country is polluted to varying degrees. Polluted soil will lead to crop yield reduction, and may even cause excessive pollutants in agricultural products, especially heavy metals, which are fatal to the human body and are not conducive to the human body. healthy. In addition, the site pollution caused by industrial and mining enterprises is...
