Embodiment 1
[0039] This embodiment is a method for treating landscaping solid organic waste using a combined process of biomass carbonization + two-stage fermentation. The method includes the following steps:
[0040] (a) Separating branches, trunks and rhizomes from landscaping solid organic waste to obtain mixed materials and remaining materials of branches, trunks and rhizomes;
[0041] (b) Break the mixed material into a mixed material with a length not greater than 13 cm and a diameter not greater than 4 cm. Then, put the crushed mixed material in a carbonization machine and crack it at 550°C for 8 minutes to separate and obtain wood tar, Condensed wood vinegar, biomass charcoal and combustible gas, then use the combustible gas as a heat source for carbonization, and collect high-temperature tail gas;
[0042] (c) Crushing the remaining materials until the particle size is not greater than 0.8cm, then, 45 parts of the remaining materials after crushing, 15 parts of chicken manure, 16...
Embodiment 2
[0048] This embodiment is a method for treating landscaping solid organic waste using a combined process of biomass carbonization + two-stage fermentation. The method includes the following steps:
[0049] (a) Separating branches, trunks and rhizomes from landscaping solid organic waste to obtain mixed materials and remaining materials of branches, trunks and rhizomes;
[0050] (b) Break the mixed material into a mixed material with a length not greater than 17cm and a diameter not greater than 6cm. Then, put the crushed mixed material into a carbonization machine, and crack it at 350°C for 12 minutes to separate and obtain wood tar, Condensed wood vinegar, biomass charcoal and combustible gas, then use the combustible gas as a heat source for carbonization, and collect high-temperature tail gas;
[0051] (c) Crushing the remaining materials until the particle size is not greater than 1.2cm, then, 40 parts of the remaining materials after crushing, 20 parts of chicken manure, ...
Embodiment 3
[0058] This embodiment is a method for treating landscaping solid organic waste using a combined process of biomass carbonization + two-stage fermentation. The method includes the following steps:
[0059] (a) Separating branches, trunks and rhizomes from landscaping solid organic waste to obtain mixed materials and remaining materials of branches, trunks and rhizomes;
[0060] (b) Break the mixed material into a mixed material with a length not greater than 15 cm and a diameter not greater than 5 cm. Then, put the crushed mixed material in a carbonization machine, and crack it at 450°C for 10 minutes to obtain wood tar, Condensed wood vinegar, biomass charcoal and combustible gas, then use the combustible gas as a heat source for carbonization, and collect high-temperature tail gas;
[0061] (c) crush the remaining materials until the particle size is not greater than 1cm, then mix 43 parts of the remaining materials after crushing, 18 parts of chicken manure, 17 parts of wat...
