Embodiment 1
[0025] Chicken manure and garden waste (flowering branches, leaves, plant stalks, etc.) from chicken farms were selected in a ratio of 7.5:2.5, respectively, and put into the thermal enzyme reactor for rapid recycling of organic waste, adding 0.1% heat-resistant enzyme and 0.05% thermophilic bacteria agent, the material temperature is 80 ℃, the stirring speed is controlled at 5r / min, the first fermentation, decomposing and exhausting, the exhaust volume per ton of material per hour is 150m 3 , the exhaust time is 18 hours; then the parameters are automatically changed to the material temperature controlled at 90 ℃, the speed of the stirring blade of the thermal enzyme reactor is 10 r / min, and the second exhaust volume is 700 m per ton of material per hour 3 , the exhaust time is 6 hours; after 24 hours of fermentation, the material is discharged, which is an organic fertilizer product, and the cooled organic fertilizer is sampled for inspection and self-inspection. 2011) and n...
Embodiment 2
[0032] The sludge and wood chips from the sewage treatment plant were added to the thermal enzyme treatment reactor for rapid recycling of organic waste in a ratio of 7:3, and 0.1% thermostable enzyme and 0.1% thermophilic bacteria composite decomposing agent were added. Parameters for the first 18 hours In order to keep the material temperature constant at 80℃, the stirring speed is controlled at 3r / min, the initial material humidity is about 65%, and the exhaust volume is 100m 3 / h; 16 hours; then use the setting program to automatically fine-tune the parameters until the material temperature is constant at 90°C, the stirring speed is controlled at 8rpm, and the induced air exhaust volume is 750m 3 / h. After 24 hours of fermentation, the organic fertilizer produced has been tested for conventional indicators, heavy metals and microbial indicators (see Table 3). :
