Abstract: An abandoned benzol refining workshop in a coking plant in Beijing was chosen as the experimental object.A foundation pit measured 10 m×10 m×4 mwas excavated as a risk management area.Micro-aeration barrier technology was applied to control benzene in the area.Results showed that anaerobic microorganisms were dominant without aeration.Aeration for 1 time could not change the anaerobic condition of deep soil,and could not meet enough O2 for aerobic microorganisms,either.Therefore,benzene could no... More
