Embodiment 1
[0025] Water hyacinth, food waste are air-dried and broken into 15-30mm, fully mixed by sludge: water hyacinth (air-dried): food waste=7: 6: 8 mass ratio proportioning, mixture moisture content is 53.7%, C / The N ratio is 27:1. Put the mixed stock into the sealed bin to start a fermentation for 10 hours, then start intermittent ventilation, 20 minutes per hour, and the air flow rate is 0.08~0.15m 3 / min·m 3 , after 12 days, the composting in the fermentation bin was changed to open-air stacking, and proper ventilation was maintained, and the compost was turned once a day, and decomposed compost was obtained after 19 days of open-air stacking. The detection found that the compost organic matter was 44.2%, TN was 1.29%, TP was 0.63%, and TK was 3.52%.
Embodiment 2
[0027] Water hyacinth, food waste are air-dried and broken into 15-30mm, fully mixed by sludge: water hyacinth (air-dried): food waste=7: 6: 8 mass ratio proportioning, mixture moisture content is 53.7%, C / The N ratio is 27:1. Put the mixed stock into the sealed bin to start a fermentation for 12 hours, and then start intermittent ventilation for 15 minutes per hour, and the air flow rate is 0.04~0.08m 3 / min·m 3 , after 11 days, the composting in the fermentation bin was changed to open-air stacking, and proper ventilation was maintained, and the compost was turned once a day, and decomposed compost was obtained after 18 days of open-air stacking. The detection found that the compost organic matter was 43.3%, TN was 1.32%, TP was 0.63%, and TK was 3.67%.
Embodiment 3
[0029] Water hyacinth, food waste are air-dried and broken into 15-30mm, fully mixed by sludge: water hyacinth (air-dried): food waste=7: 4: 3 mass ratio proportioning, the mixture moisture content is 52%, C / The N ratio is 23:1, put the mixed stock into the sealed bin to start a fermentation for 12 hours, and then start intermittent ventilation, ventilation for 20 minutes per hour, and the air flow rate is 0.04~0.08m 3 / min·m 3 , after 11 days, the composting in the fermentation bin was changed to open-air stacking, and proper ventilation was maintained, and the compost was turned once a day, and decomposed compost was obtained after 18 days of open-air stacking. The detection found that the compost organic matter was 44.2%, TN was 1.49%, TP was 0.53%, and TK was 3.07%.
