Abstract

The invention relates to a test device for treating petroleum hydrocarbon pollutants in underground water and application of the test device, and belongs to the technical field of underground water pollutant treatment. The test device comprises a sewage container, a submersible pump, an oxidant container, an oxidant injection pump, an overflow groove, a reaction column and a filter inner core, wherein a sewage injection port is formed in the head end of the reaction column; a liquid outlet is formed in the tail end of the reaction column; the reaction column is filled with a seepage medium; anoxidant injection pipe, a sampling port and a filter inner core are sequentially arranged in the direction from the sewage injection port to the liquid discharge port; the oxidant container is connected with the interior of the reaction column through the oxidant injection pump and the oxidant injection pipe; the sewage container is connected with the sewage injection port through the submersiblepump; and the overflow groove is connected with the liquid outlet. The invention also discloses a method for treating petroleum hydrocarbon pollutants in underground water. The test device provided by the invention can simulate the dispersion condition of a single release point source in a fluid, and provides a basis for the design of a permeable reactive barrier in the later period.

Description

technical field [0001] The invention belongs to the technical field of groundwater pollutant treatment, in particular to a test device for treating petroleum hydrocarbon pollutants in groundwater and its application. Background technique [0002] Permeable reactive wall (PRB) is a treatment system for removing pollutants in the groundwater environment with small aquifer thickness and shallow depth, and can be used to treat petroleum hydrocarbon pollutants in groundwater. Osmotic reaction walls are generally constructed in the transport and dispersion area of ​​pollutants in the groundwater seepage field. According to the chemical composition and control requirements of pollutants, they are filled with granular media with functions such as adsorption, acid-base neutralization, or ion exchange to absorb or remove General acid and alkali, heavy metals and trace organic pollutants can be used to divide the polluted area of ​​the groundwater environment, purify the pollutants tra...
