Abstract

The invention discloses a double-phase vacuum suction simulation system and a simulation method thereof, and belongs to the technical field of recovery technology for petroleum environmental pollution. The simulation system comprises: a three dimensional simulation zone, pollution source, a double-phase vacuum suction well, a monitoring well, a suction pump, a fluviograph, a water pump, an air compressor, a steam generator and the like. According to the present invention, a transmission process, a migration process, a conversion process and a biodegradation process of nonaqueous phase liquidsof petroleum pollutants in groundwater are simulated through adopting a multiphase and multicomponent simulation method, such that the double-phase vacuum recovery process is effectively simulated, parameter calibration problems during the double-phase vacuum suction technology design process are solved well, a optimal design is ensured. According to the simulation model, objective reality of theunderground layer can be reflected more veritably, and pollution status and recovery effect of the soil and the underground water can be well simulated and predicted.

Description

technical field [0001] The invention belongs to the technical field of petroleum environmental pollution restoration, and in particular relates to a two-phase vacuum suction simulation system and a simulation method thereof. Background technique [0002] In recent years, groundwater pollution caused by the petroleum industry has become a serious worldwide environmental problem. Every year, a large amount of organic pollutants enter the groundwater and soil due to oil extraction, transportation, storage and accidental leakage, causing serious damage to the ecological environment. Among these pollution sources, underground organic leakage has become the most important underground pollution source. Pollutants from leakage of underground oil storage tanks, underground pipelines, petroleum processing equipment, etc. often have the "three effects" of carcinogenicity, teratogenicity, and mutagenicity, and are difficult to remove through natural degradation processes in groundwater...
