NOVELTY - The apparatus comprises a condenser (23) rotatably arranged within a process chamber (22) of a dryer, and condensing the steam generated from organic waste. A heat refluxing part (25) heats a workpiece. The process chamber is connected to a downstream side of a gas-liquid separator for separating condensed water and air using wastewater treatment and activated sludge processes. A suction pump sucks the condensed water and air in the gas-liquid separator. An ozone reactor (6) processes the air separated from the gas-liquid separator. A water storage tank is connected with a transducer.    USE - The apparatus is useful for fermenting and drying workpiece in a sewage disposal plant, where the workpiece comprises sludge generated from industrial waste and kitchen refuse.    ADVANTAGE - The condensed water and air are mixed with the cooling water and the nanobubble is dispersed in the condensed water for long time without ventilation in the reaction bath, which is in tight state thus removing foul smell from the workpiece. The condensed water and the air from the process chamber can be efficiently processed, so that the drying efficiency of the workpiece can be enhanced.    DETAILED DESCRIPTION - The apparatus comprises a condenser (23) that is rotatably arranged within a process chamber (22) of a dryer and condenses the steam generated from organic waste. A heat refluxing part (25) heats a workpiece. The process chamber is connected to a downstream side of a gas-liquid separator for separating condensed water and air using wastewater treatment and activated sludge processes. A suction pump sucks the condensed water and air in the gas-liquid separator. An ozone reactor (6) processes the air separated from the gas-liquid separator. A water storage tank is connected with a transducer including a calculator. A distributing valve distributes the condensed water induced from the gas-liquid separator, which is installed in a pipe. A cooling device supplies cooling water as cooling medium in a vacuum pump (5) and the ozone reactor. A kneading section of the dryer is provided with a hollow rotary shaft, which is supported in a bearing. The bearing is installed with the dryer. A casing of a transfer wing is connected to the rotary shaft, and forms spiral shape in an external diameter of the rotary shaft. A spiral pipe is arranged in the external diameter of the spiral pipe. A nanobubble generation apparatus produces the nanobubble of the air in the condensed water. Aerobic microorganism is added in the condensed water in a reaction bath for condensing organic compound, where the organic compound is cohered with the action of the aerobic microorganism.
