METHOD, INJECTOR AND SYSTEM FOR THE REMEDIATION OF ANOXIC MARINE SEDIMENTS

摘要

The invention relates to a method and system for the remediation of anoxic marine sediments, which comprises: suctioning seawater using a suction pump; storing the suctioned sea water in a tank; carrying out an oxygenation treatment of the sea water in the tank, using a bubble system, until the water is saturated in oxygen, said bubble system being formed by a plurality of diffusers and an air blower, the oxygen concentration being measured with an oximeter; and injecting, by means of a drive pump, the saturated water into a hydraulic circuit comprising tubes with a plurality of injectors that are introduced into the sediment to be treated, the injectors having perforations through which the oxygen-saturated water is injected with a sequence of 90-180 minutes of rest and 50-70 minutes of injecting into said sediment.
