Preferred Method: Inoculating a composite microbial inoculum into compost for promoting fast corrupting specifically comprises: (a) mixing crushed straw with a length of 30 to 50 mm with fresh animal dejection (such as the cow dropping with a water content of 70 to 90%), then controlling the water content of the mixture at 65%, and then regulating the pH value to about 7.6 by adding lime powder; (b) inoculating the composite microbial inoculum of 0.3 to 0.5% of the compost by weight into the compost, then turning and mixing well, and then transferring into a fermentation tank to carry out aerobic fermentation, where the fermentation tank is a hand-placed concrete structure with a length of 1000 mm, a width of 1500 mm and a height of 800 mm, the central of the tank bottom is equipped with an iron grid for discharging residual waste water immediately, and the position of 90 mm away from the bottom of the fermentation tank is equipped with a ventilation pipe for the benefit of aerobic fermentation and volatilization of the moisture of the compost; (c) symmetrically infusing air into the fermentation tank through an air compressor, then controlling the amount of infused air in the stage of heat and the stage of high temperature fermentation at 2 to 4 m3/hour through a gas flow meter, to promote the rapid rise of the compost temperature and to accelerate the fermentation speed of high temperature compost, and then controlling the amount of infused air in the temperature reduction fermentation stage at 0.5-1.5 m3/hour; (d) measuring the temperature and turning the stack at regular time, namely measuring the temperature of the compost material in the fermentation tank by inserting the temperature gauge into the position of 25 to 30 cm below the surface of the compost body and simultaneously recording the environment temperature around the same, and then turning the compost for every three or four days according to the change of the fermentation temperature; and (e) regularly detecting, namely, regularly sampling from the different positions of the compost, and then analyzing the biological indexes and physicochemical indexes of the sample.
