Abstract

The invention discloses a heavy metal-contaminated soil restoration method and equipment thereof. The heavy metal-contaminated soil restoration method includes the steps of crushing, sieving, cleaning, sedimentation, chemical addition reaction and standing maintenance. The equipment in the method includes successively connected crushing equipment, vibrating screening equipment, stone washing equipment, sedimentation tank, defiltration equipment, dosing equipment and stirring equipment. The heavy metal-contaminated soil remediation method of the present invention has a high degree of systematicness and continuous operation, which is beneficial to the overall control and management of the contaminated soil treatment process, reduces the construction work surface, reduces the secondary pollution of the environment, and improves the utilization rate of resources in the system. And it can improve the effect and efficiency of soil remediation and reduce the cost of soil remediation.

Description

technical field [0001] The invention relates to the technical field of remediation and treatment of polluted soil, in particular to a method for remediating heavy metal-contaminated soil and equipment used therein. Background technique [0002] According to the "National Soil Pollution Survey Bulletin" issued by the Ministry of Environmental Protection and the Ministry of Land and Resources in April 2014, the overall situation of the national soil environment is not optimistic. protrude. The pollution types are mainly inorganic, mainly including chromium, cadmium, mercury, arsenic, lead, copper, zinc, nickel and so on. Soil pollution not only causes serious harm to the ecological environment and human health, but also hinders the development of my country's economy. [0003] The distribution of heavy metal soil pollution is wide, the amount of pollution is large, and the cost of treatment is high, and the treatment period is long. If the concrete, bricks, stones and other...
