Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] see figure 1 , the embodiment of the present invention provides an ex-situ chemical remediation system for polluted soil, which is mainly used to remove pollutants in polluted soil through chemical agents. Of course, different chemical agents should be selected for different types of pollutants, such as pollutants For organic substances or heavy metals, different chemical agents should be selected accordingly. The restoration system includes material b...

Abstract

The invention relates to environmental protection equipment, and provides a polluted soil heterotopic chemical restoration system, which includes a material box for storing chemical agents and a mixing box for storing polluted soil. The mixing box is provided with a rotating shaft that can rotate around its own axis. A number of stirring rods are arranged on the rotating shaft, and each stirring rod is set from the surface of the rotating shaft to a direction away from the rotating shaft. nozzle. In the restoration system of the present invention, tubular stirring rods are arranged on the rotating shaft, and high-pressure nozzles are arranged at the ends of each stirring rod. The nozzle is sprayed into the soil, which can form a sufficient mixture between the soil and the chemical agent, which not only has high efficiency, but also uses less chemical agent, and does not need to dry the repaired soil, which is very convenient.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to an ex-situ chemical restoration system for polluted soil. Background technique [0002] my country's land resources are in short supply, and soil pollution is severe. With the development of my country's industry and agriculture and the acceleration of urbanization, as well as the adjustment of my country's industrial structure and the acceleration of urbanization, large and medium-sized cities across the country have implemented the policy of "retreating from two to three" and "retreating from cities and entering parks". A large number of polluting enterprises involved in chemical industry, metallurgy, petroleum, transportation, light industry and other industries have been relocated or closed down successively. In the process of redevelopment and utilization of the contaminated soil left by the relocation of a large number of industrial enterprises, the toxic and harmful su...
