Description:
Land treatment is a method of handling wastes that are used by the petroleum refinery industry and others. This method allows the simultaneous treatment and final disposal of the wastes. The soil properties and biota are depended upon to degrade, transform or immobilize the hazardous constituents of the wastes. A mathematical model of the land treatment process has been developed which will simulate the movement of contaminants as oily wastes are degraded. The model examines the fate of these constituents in the soil, oil, water and air phases of the treatment system. The model assumes no dispersion, local equilibrium, linear partitioning of the contaminant between phases, volatile losses by a modified Thibodeaux-Hwang approach, first-order degradation kinetics, no migration of oil after application, a uniform soil profile, and constant water flux throughout the treatment zone.
