▎ 摘　　要

NOVELTY - The device has a housing (111) provided with an inlet (112) and an outlet (114), through which the liquid is intended to enter and leave the housing, respectively. A ferrous cation generator is provided with an iron anode (118), housed in the casing. A graphene and/or silica and/or phosphorene cathode (119) is partially compressed between the anode and a housing wall. The graphene and/or silicane and/or phosphorene cathode has the form of a layer covering more than 50% of an interior surface of the casing. The layer is set in contact with several iron blocks traversed by the channels (122) allowing the circulation of the liquid. USE - Device for treating liquid, discharged from production of oil or gas, mining extraction, hydraulic fracturing, metering or treatment of drinking or non-potable water, comprising organic pollutant such as volatile and semi-volatile organic compounds, polychlorinated biphenyl (PCB), pesticides, herbicides, dioxins, furans, explosive products and their products of degradation, humic products and dyes (all claimed) in target such as industrial building, residential building or tertiary building, hospital, school or wastewater treatment plant. Uses include but are not limited to acetylenes, alcohols, aldehydes, alkanes, aromatic compounds, carboxylic acids, alkenes, in particular chlorinated alkenes, ketones, nitrogenous organic compounds, olefins, phenols, organic sulfur compounds, and mixtures. ADVANTAGE - The ferrous cations are generated without the supply of electrical energy, such that the efficiency of the treatment is improved. The contact surface between the anode and the cathode is increased, and thus the efficiency of the generator is increased. The deformability of graphene advantageously allows the close contact of the anode and cathode with large manufacturing tolerance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) an installation for treating liquid containing organic pollutant; and (2) a method for treating liquid containing organic pollutant. DESCRIPTION OF DRAWING(S) - The drawing shows a longitudinal sectional of the hydrodynamic reactor used in treatment device.
