Problems solved by technology

However, the use of this technology will be limited by the place. It is only suitable for the place where the soil air lift technology is feasible. At the same time, the effect of the bioinjection method is also affected by petrography and soil stratigraphy. Before the air enters the unsaturated zone, it should be As far as possible from the coarse porous layer, avoid affecting the contaminated area
In addition, it is not effective in dealing with refractory organic matter

Abstract

The invention discloses a microporous diffuser and a method for treating petroleum pollutant, belonging to the technical field of treating petroleum pollutant. The diffuser comprises a foam maker, a compressor, an interval controller, a pressure pump, a timer, a power supply, an air inlet pipe, a telescopic filler, a water pump, an ozone pipe and an outflow check valve. The microporous diffuser can generate superfine microbubbles of different apertures, and inject the superfine microbubbles in a subterranean layer so as to remove petroleum pollutant. The diffuser has the advantages of compactstructure, easiness for operation, fast effect and high reliability, and is especially suitable for removing difficultly degradable organic pollutants in the subterranean layer.

Description

technical field [0001] The invention belongs to the technical field of petroleum pollutant treatment, and in particular relates to a microporous diffuser and a method for treating petroleum pollutants. Background technique [0002] Petroleum organic pollutant pollution of soil is another major pollution after pesticides and heavy metals in recent years. Petroleum is mainly a mixture of alkanes, naphthenes and aromatic hydrocarbons, which have the potential of carcinogenic, teratogenic and mutagenic. Crude oil is scattered on the ground during oil extraction and transportation. With the continuous development of the petroleum industry, the organic pollution caused by petroleum has gradually become the focus of attention. With the continuous development of oil and gas exploration and development, the oil pollutants produced in the production process are increasing day by day, and the composition is becoming more and more complex. [0003] Before the 1980s, the treatment of ...
