Embodiment
[0037] The implementation process of this embodiment is in a steel slag landfill site in Ma'anshan City, Anhui Province. The plot covers an area of about 27129m 2 , Due to historical reasons, a large amount of industrial solid waste was buried. Before the remediation, the catchment area in the site was blue-green, and white sediment was clearly visible at the bottom. The vegetation was severely damaged, and there were potential environmental risks.
[0038] (1) Attribute investigation of solid waste in informal landfills:
[0039] ① Carry out traceability analysis to determine that the industrial solid waste in landfill is steel slag generated in the process of iron and steel smelting. In the relevant EIA documents, it is characterized as general industrial solid waste;
[0040] ② Carry out on-site investigation and sampling. Due to the relatively clear source and single nature of solid waste, 30 solid waste samples were collected. According to expert judgment and prelimin...

The invention discloses a technical method for evaluating a cleaning effect after illegal disposal of general industrial solid wastes. The method comprises the specific steps of identifying the general industrial solid wastes, determining the position of the solid wastes, stripping the solid wastes from undisturbed soil, judging a cleaning state and evaluating the cleaning effect. According to the technical method, the current situation that a cleaning effect evaluation system for general industrial solid waste is lacked is made up, and the problems of unnecessary expenditure and high disposal load caused by incomplete or excessive cleaning of general industrial solid waste in a polluted land parcel, particularly excessive sentences for handling an environment pollution case and the like are fully solved. In addition, the method is clear in thought, accurate in problem recognition, low in cost, capable of being comprehensively popularized and fully suitable for a large number of polluted land parcels, such as regular or irregular landfills and decommissioned sites of industrial enterprises, related to ectopic cleaning of general industrial solid waste at present.
Description
technical field [0001] The invention relates to the technical field of risk management, control and restoration of polluted land plots, and in particular relates to a technical method for evaluating the cleaning effect of general industrial solid wastes requiring ex-situ cleaning and disposal. Background technique [0002] Since the implementation of policy documents such as the "Ten Soil Articles" and "Waste Removal Action", the investigation of my country's informal solid waste landfills, the promotion of forensic identification of environmental damage, and the comprehensive investigation of soil environmental quality in key industries and enterprises across the country, a large number of general The industrial solid waste cleaning work faces the problem of difficult acceptance. At present, the cleaning effect of residual hazardous wastes on construction land in my country is clarified in the Technical Guidelines for Soil Pollution Risk Control and Restoration Monitoring of...
