DECONTAMINATION TREATMENT OF WATER CONTAMINATED BY EMERGENT POLLUTANTS AND/OR MICROPOLLUTANTS, ESPECIALLY BY ORGANOCHLORINE COMPOUNDS

摘要

The present invention relates to a process for decontaminating water contaminated by emergent pollutants or micropollutants, characterized in that it comprises a step of injecting said contaminated water into a device comprising a vertically filtering planted organic filter, which planted organic filter comprises: an inlet for the contaminated water to be treated; an outlet for said contaminated water after being treated; filtration and decontamination means interposed between the inlet for said contaminated water and the outlet, characterized in that said filtration and decontamination means take the form of a planted organic substrate composed of a compost and insoluble aggregates, making it possible for said organic substrate to maintain a permeability of at least 40 litres per hour per m², preferably at least 70 litres per hour per m² and particularly preferably at least 100 litres per hour per m². The invention also relates to the use of such a device for decontaminating water contaminated by emergent pollutants or micropollutants.
