Abstract

The invention discloses a remediation device and method for semi-in-situ treating of a volatile organic compound pollution site. The remediation device for semi-in-situ treating of the volatile organic compound pollution site comprises a slotting pipe, wherein the slotting pipe is embedded into the pollution site; one end of the slotting pipe is connected with a vortex air pump located on the earth surface through a pipeline; a capsule pressure gauge and a vortex shedding flowmeter are sequentially arranged on the pipeline between the vortex air pump and the slotting pipe; and a soil gas probeis arranged in the pollution site. The remediation device for semi-in-situ treating the volatile organic compound pollution site disclosed by the invention is simple in structure, less in work amountwhen in use, high in applicability and good in remediation effect.

Description

technical field [0001] The invention relates to the technical field of volatile organic compound treatment, in particular to a restoration device and method for semi-in-situ treatment of volatile organic compound polluted sites. Background technique [0002] Due to the different points of concern, the definition of volatile organic compounds, that is, VOCs, also has its own emphasis. The US ASTMD3960-98 defines it as any organic compound that can participate in atmospheric photochemical reactions; the World Health Organization defines the melting point below room temperature and the boiling point at 50 Volatile organic compounds between ℃ and 260 ℃ are defined as total volatile organic compounds (TVOC); BASF also believes that VOCs should be defined according to their boiling point. The most common view is that VOCs refer to those organic substances whose boiling point is lower than or equal to 250°C. [0003] VOCs outdoors mainly come from fuel combustion and transportatio...
