Embodiment 1
[0037] In this embodiment, the specific steps for rapid aerobic composting of residual sludge and corn stalks (with a particle size of 1 to 5 mm) after sewage treatment in a food factory are as follows:
[0038] (1) Mixing: Mix the excess sludge and corn stalks from food factory sewage treatment in a ratio of 6:4. / N) ratio is 25, moisture content is 60%, puts into the composting reactor after mixing, and keeps stirring.
[0039] (2) Staged aerobic composting: the composting temperature is controlled at 35°C, and the ventilation rate is 5.5m 3 / h, composting for 12h; then, the composting temperature is controlled at 55°C, and the ventilation rate is 10m 3 / h, composting for 58h; finally, the composting temperature is controlled at 65°C, and the ventilation rate is 5.5m 3 / h, composting 2h. At the end, the material seed germination index was 74.58%, basically decomposed.
[0040] (3) Post-decomposition: take out the material after the staged aerobic composting, adjust the mo...
Embodiment 2
[0042] In this embodiment, the specific steps for rapid aerobic composting of excess sludge and corn stalks (with a particle size of 1 to 5 mm) by using sewage from a food factory are as follows:
[0043] (1) Mixing: Mix the remaining sludge and corn stalks from the sewage treatment of food factories in a ratio of 9:1. The moisture content of the remaining sludge and corn stalks is 80% and 12% respectively, so that the carbon and nitrogen of the compost raw materials ( C / N) ratio is 15, moisture content is 55%, puts into composting reactor after mixing, and keeps stirring.
[0044] (2) Staged aerobic composting: the composting temperature is controlled at 30°C, and the ventilation rate is 3.5m 3 / h, compost for 24h; then, control the compost temperature at 60°C, and the ventilation rate is 12m 3 / h, composting for 47h; finally, the composting temperature is controlled at 75°C, and the ventilation volume is 3.5m 3 / h, composting 1h. At the end, the material seed germination ...
Embodiment 3
[0047] In this embodiment, the specific steps for rapid aerobic composting of excess sludge and corn stalks (with a particle size of 1 to 5 mm) by using sewage from a food factory are as follows:
[0048] (1) Mixing: Mix the excess sludge and corn stalks from food factory sewage treatment in a ratio of 5:5. / N) ratio is 30, moisture content is 65%, puts into the composting reactor after mixing, and keeps stirring.
[0049] (2) Stage-by-stage aerobic composting: the composting temperature is controlled at 40°C, and the ventilation rate is 7.5m 3 / h, composting for 10h; then, control the composting temperature at 50°C and the ventilation volume at 7m 3 / h, composting for 59h; finally, the composting temperature is controlled at 60°C, and the ventilation rate is 3.5m 3 / h, composting 3h. At the end, the material seed germination index was 68.72%, basically decomposed.
[0050] (3) Post-decomposition: take out the material after the staged aerobic composting, adjust the moistu...
