Abstract

The invention relates to a vehicle-mounted oily sludge microbial degradation and aeration-extraction treatment device which comprises a material storage device, an aeration-extraction device and a stirring device. The material storage device comprises a stirring tank, a feed opening and a discharge opening; the aeration-extraction device comprises an air compressor, a blast pipe, an air-pumping storage tank and a waste gas treatment detection tank; the stirring device comprises an independent motor, an auger and the like. The vehicle-mounted oily sludge microbial degradation and aeration-extraction treatment device provided by the invention can perform on-site or mobile treatment on pollutants such as petroleum hydrocarbon and volatile organic compounds in oily sludge on a polluted site inconvenient for the construction of a large-scale treatment device through a vehicle-mounted mobile processing device, so that the treatment of the oily sludge on the polluted site is more convenient.

Description

technical field [0001] The invention relates to the field of soil remediation of oil-contaminated sites, in particular to a vehicle-mounted oily sludge microbial degradation and aeration-extraction combined treatment device and method, which can treat various It is inconvenient to remove petroleum hydrocarbons, VOCs and easily degradable organic pollutants in the soil where it is inconvenient to build a large-scale treatment device. Background technique [0002] With the rapid development of petrochemical enterprises, the exploitation of oil fields is also increasing, and a large amount of oily sludge will be generated in the process of oil extraction, transportation, refining and storage. Moreover, with the deep exploitation of the oil field, the muddy water content in the crude oil produced will also become higher and higher. These oily sludges usually contain water, oil, VOCs, sediments, heavy metals and other toxic and harmful solid substances. If not treated in time, t...
