NOVELTY - High temperature aerobic composting stage oxygen ventilation and temperature feedback automatic control includes obtaining an actual value of a stack temperature and oxygen concentration through a temperature sensor and oxygen sensor, transmitting the signal to a programmable logic controller and an upper computer configuration control software, and automatically adjusting the electromagnetic valve opening degree to control the stack ventilation quantity according to the predetermined working control parameters.    USE - High temperature aerobic composting stage oxygen ventilation and temperature feedback automatic control (claimed).    ADVANTAGE - Flexible control of the ventilation quantity is realized. The compost is kept in a desired temperature range and oxygen concentration range. The method has short treatment period and maintains an aerobic environment of the compost. By virtue of using a low-ventilation continuous running strategy, the power needed by a fan device is greatly reduced, and harmlessness and resource utilization of the compost are realized.    DETAILED DESCRIPTION - High temperature aerobic composting stage oxygen ventilation and temperature feedback automatic control comprises:    (A) setting a temperature at 25-30 degrees C, inserting a temperature sensor into a center block, connecting the temperature sensor with a controller and a sensor power supply, and raising the temperature of the stack;    (B) controlling the temperature at a maximum of 50-55 degrees C, providing an oxygen sensor, reading the stack oxygen concentration value, and adjusting the ventilation quantity by adjusting the electromagnetic valve opening degree, so that an oxygen concentration value of the stack is maintained at 8-15% or more;    (C) maintaining a maximum temperature of 55-65 degrees C for 7-10 days;    (D) controlling the ventilation of the stack by the electromagnetic valve, rapidly dehydrating, and cooling to room temperature for 2-5 days; and    (E) obtaining an actual value of the stack temperature and oxygen concentration through the temperature sensor and oxygen sensor, transmitting the signal to a programmable logic controller and an upper computer configuration control software, and automatically adjusting the electromagnetic valve opening degree to control the stack ventilation quantity according to the predetermined working control parameters.
