Method and device for the treatment of effluents containing the raw industrial or agricultural chemical (fungicides, insecticides, phytosanitary)

摘要

The procedure uses a plant with a water tank (35) for washing out containers that have held chemicals, a pump (25) and an electrolytic tank (12) in which the filtered water is degraded by flocculation. the tank contains electrodes (06) fed by a direct current converted from the mains alternating current in a control unit (28) that maintains a constant amperage during the electrolysis process. The treatment process operates in a closed circuit, with the filter taking out the flocculated materials and other pollutants each time the water is pumped through it, and a second tank (33) allows a low pressure to be created in it so that water can be evaporated at a lower temperature and chemicals separated from it by gravity. The evaporated water is collected in a buffer tank (21), and chemicals are drawn off and destroyed.
