Case Analysis of Remediation Engineering for PAHs Contaminated Sites
With the popularization of ecological civilization in the new era,the public's awareness of environmen-tal protection has been further enhanced,and higher requirements have been put forward for ecological environ-ment governance.Under the guidance of the current theme of developing new productive forces,it is necessary to continuously promote the allocation ratio of efficient,precise,and green low-carbon remediation elements to em-power its governance technology.Based on the above ideas and concepts,the remediation project of a polluted coal to gas plant was selected as the research object.The characteristics and pollution status of polycyclic aromatic hydrocarbons were summarized.On the basis of analyzing common remediation technologies,detailed discussions were conducted from the aspects of project overview,application requirements,technical routes,implementation plan,detection and effect evaluation.At present,the project has completed remediation,and the characteristic pol-lutants such as polycyclic aromatic hydrocarbons and petroleum hydrocarbons in soil and groundwater have been detected to reach the target values determined by the Detailed Site Investigation and Risk Assessment Report and the Restoration Technical Plan.There is no secondary pollution to the surrounding area during the construction process.The smooth implementation of this project is of great significance for improving the safe utilization of land resources and ecological environment protection,and also provides a reference for similar polluted site resto-ration projects.
