NOVELTY - A control system for process of mixing compost of mud and organic garbage comprises reactor (1), fan (2) connected with reactor, temperature displaying instrument, single chip (4), relay electrically connected with fan, gas flow controller, and thermocouple set. All thermocouples are installed in the compost raw material. The thermocouple set is connected with temperature displaying instrument signal. The temperature displaying instrument is connected with single chip signal. The single chip is connected with relay signal.    USE - System for controlling the process of mixing compost of mud and organic garbage (claimed).    ADVANTAGE - The system achieves harmless effect, amount reduction and stabilization of the mud and organic garbage; and controls based on real situation of the composting system, thus reducing energy consumption during the process of composting and improving fertilizing efficiency of compost product.    DETAILED DESCRIPTION - A control system for process of mixing compost of mud and organic garbage comprises reactor, fan (2) connected with reactor, temperature displaying instrument, single chip (4), relay electrically connected with fan, gas flow controller, and thermocouple set. All thermocouples are installed in the compost raw material. The distance between the thermocouple close to the reactor bottom and the head face bottom is 15-25 cm. The distance between each two thermocouples is 10-20 cm. The thermocouple set is connected with temperature displaying instrument signal. The temperature displaying instrument is connected with single chip signal. The single chip is connected with relay signal. An INDEPENDENT CLAIM is included for a method for controlling the process of mixing compost of mud and organic garbage comprising monitoring temperature of the pile in real time with thermocouple, when temperature T1 of the pile is measured to be less than 55-65 degrees C, the single chip would control the fan to run 3-5 minutes and then stop working for 15-20 minutes, circulating in accordance with such mode to ventilate and supply oxygen to the reactor intermittently, and air quantity of the fan is detected by gas flow meter which is controlled at 0.8-12 m3/hour; using single chip to control the fan to blast continuously to the pile, where air quantity of the fan is controlled to 0.8-12 m3/hour until temperature of the pile is less than 50-60 degrees C; using the single chip to control the fan to ventilate and supply oxygen in accordance with the mode of running 3-5 minutes and then stopping running for 15-20 minutes, where air quantity of the fan is controlled to 0.8-12 m3/hour.    DESCRIPTION OF DRAWING(S) - The drawing is a schematic block diagram of control system for the process of mixing compost of mud and organic garbage.    Reactor (1)    Fan (2)    Single chip (4)
