NOVELTY - Continuous batch autothermal aerobic composting, comprises (i) piling the mixed compost material to a tank body to form static piling, and performing aerobic fermentation, (ii) taking a high temperature pile as a heating source, introducing the hot gas generated by the heating source into the primary pile, (iii) terminating heating, and changing with another heating source pile for continuously supplying heat, and continuing to ferment, (iv) taking compost sludge as an initial material, and transferring the remaining compost sludge into warehouse, and (v) repeating the steps (i)-(iv).    USE - The method is useful for continuous batch autothermal aerobic composting.    ADVANTAGE - The method shortens the compost period; and reduces the operation cost, and also reduces the discharge of bad odor in sludge composting process.    DETAILED DESCRIPTION - Continuous batch autothermal aerobic composting, comprises (i) piling the mixed compost material to a tank body for 1-3 days to form static piling, and performing aerobic fermentation for the static piling, where the number of tank body is 6-24, (ii) taking a high temperature pile with a temperature of 60-70 degrees C as a heating source, carrying out aerobic fermentation for 2-3 days, and introducing the hot gas generated by the heating source into the primary pile through an aeration pipe at the bottom of the pile by a draught fan, (iii) terminating heating, when the pile temperature of the heating source is reduced to 50-55 degrees C, and changing with another heating source pile for continuously supplying heat, when the primary pile reaches to 35-40 degrees C, terminating the receiving heat supply, and continuing to ferment for 3-5 days to form compost sludge, (iv) taking 10-50% compost sludge as an initial material, and transferring the remaining rotten sludge into finished product warehouse, and (v) repeating the steps (i)-(iv). An INDEPENDENT CLAIM is also included for continuous batch autothermal aerobic composting device, comprising a tank body. The bottom of the tank body is provided with a ventilation pipe. The ventilation pipe is radially provided with pores. The two ends of the ventilation pipe are provided with an electromagnetic valve of a control switch. The number of the groove is 6-24. A temperature sensor is placed on the tank body. The temperature sensor is connected to the thermocouple for detecting the temperature. An engine fan and a microcomputer is set out of the tank body. The draught fan and the temperature sensor are connected with the microcomputer. The draught fan is connected with the pipeline through the air pipeline. The microcomputer is suitable for controlling the starting or closing electromagnetic valve according to the temperature signal. The tank body forms static piling tank body.
