Study on the Impact of Demolition Activities of Abandoned Coal Gasification Plant Equipment on Soil Environmental Pollution
The study focused on monitoring the changes in petroleum hydrocarbons and organic pollutants in the soil before and after the removal of equipment at an abandoned coal gasification plant.The results showed that after the equipment removal,there was a significant increase in the concentrations of petroleum hydrocarbons,benzo(a)pyrene,naphthalene,and benzene in the soil compared to before removal.The areas affected by the removal activities included the equipment decontamination and dismantling area,water treatment area,temporary hazardous waste storage area,and construction access road.The removal activities had the greatest impact on the soil in the large equipment dismantling area and equipment decontamination and dismantling zone 1 in terms of spatial distribution.Before the removal,the soil samples in these areas had concentrations that were below the relevant standard limits.However,after the removal,the concentrations exceeded the limits.The main reason for the change in the degree of soil contamination before and after the removal of the equipment is the incomplete implementation of pollution prevention and control measures according to the planned requirements during the removal activities,as well as the lack of environmental supervision.
