Abstract

The invention discloses a heavy metal contaminated soil remediation method and a device thereof. The heavy metal contaminated soil remediation method comprises the following steps: crushing, screening, washing, precipitating, adding chemicals and reacting, standing and maintaining. The device used by the method comprises a crushing device, a vibrating and screening device, a washing device, a precipitating tank, a filtering device, a chemical adding device and a stirring device which are sequentially connected with one another. The heavy metal contaminated soil remediation method has high systematicness and continuous operation performance; the contaminated soil treatment process can be comprehensively controlled and managed; the construction operation area is reduced; the secondary pollution to the environment is reduced; the utilization rate of resources in the system is increased; the soil remediation effect and remediation efficiency can be improved; and the soil remediation cost can be reduced.

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...
