<p>The invention relates to a method and device for the thermal oxidation of organic sludge produced by polluted-water-treatment plants. The inventive method consists in: stirring an organic sludge having a dryness of between 12 and 18 % with steel balls having a temperature of between 145 DEG C and 165 DEG C, such as to produce a mixture of dry combustible particles and balls; and subjecting the mixture thus produced to a hot air stream having a temperature of between 350 DEG C and 395 DEG C, thereby causing the thermal oxidation of the dry particles. The method and device can be used to produce very compact units in order to satisfy sludge disposal requirements. The invention is particularly suitable for the in situ thermal oxidation of organic sludge produced by small and medium treatment plants.</p> |
