摘要

The procedure for treating liquid/viscous effluents (4) such as sludge, comprises storing the effluents in a storage tank (3), introducing the effluents into a biological bed (2) by capillarity, pretreating the stored effluents, and activating microorganisms in the biological bed. Degradation of plant health products comprises a step of introducing the effluents into the biological bed made up of a substrate having micro-organisms to degrade the effluents in which the substrate is maintained at 12-35[deg]C. The procedure for treating liquid/viscous effluent (4) such as sludge, comprises storing the effluents in a storage tank (3), introducing the effluents into a biological bed (2) by capillarity, pretreating the stored effluents, and activating micro-organisms in the biological bed. Degradation of plant health products comprises a step of introducing the effluents into the biological bed made up of a substrate having micro-organisms to degrade the effluents in which the substrate is maintained at 12-35[deg]C. Moisture in the biological bed contains retention capacity (60-120%) of the substrate. A given volume of effluents are introduced into the biological bed according to- an evaporation rate of the bed, and a retention rate of the product by fixing on the substrate of the bed. The effluents are introduced into the biological bed in such a way that the evaporation rate of the biological bed contains 500-1000 liters of the water effluent. During the pretreatment acidity i.e. a pH value of the stored effluents are modified. The pretreatment step comprises introducing organic matter and microbial inoculums into the effluents to stimulate the products. The activation stage of the microorganisms comprises refreshing the biological bed. The refreshed biological bed is obtained by introducing an air from the bottom of the bed. An independent claim is included for a water treatment device.
