Embodiment 1
[0026] Example 1. The invention discloses a method for making bio-organic fertilizer by using municipal sludge. It includes the following steps:
[0027] (1) Material preparation: mix and stir urban sludge, chicken manure, pig manure, cow manure, organic materials, compound decomposing bacteria agent and water according to a certain proportion;
[0028] (2) Solid solution treatment: Put the above-mentioned prepared materials into a high-pressure mixer for solid solution treatment, so that all materials and decomposed bacteria can achieve microscopic uniformity and refinement in a semi-solid state, and each gram of weight of various materials And the content of decomposing bacteria is uniform;
[0029] (3) Aerobic fermentation: put the material after the above solid solution treatment into the fermentation tank, use the turning machine provided in the fermentation tank to turn over the material once a day to achieve the purpose of fully dissolving oxygen, and ferment for 10 d...
Embodiment 2
[0036] Example 2. The invention discloses a method for making bio-organic fertilizer by using municipal sludge. Wherein the time of aerobic fermentation is 9 days.
[0037] The quality formula for material preparation is as follows: 9% of urban sludge, 28% of pig manure, 40% of chicken manure, 17% of straw, 3% of compound decomposing bacteria agent, and the rest is fly ash, and then add water to adjust the water content to 55%.
[0038]The mass ratio of additives is: urea 9%, monoammonium sulfate 6%, phosphate rock powder 4%, potassium sulfate 6%, borax 0.6%, zinc sulfate 0.8%, magnesium sulfate 0.8%, manganese sulfate 0.8%, iron sulfate 0.8% % and 2% of clay, and the rest are pulverized materials.
[0039] The technical conditions of the solution treatment are: the speed of the high-pressure mixer is 58 rpm, the temperature is 55°C, the pressure is 0.25Mpa, and the solution time is 0.9 minutes.
[0040] All the other are with embodiment 1.
Embodiment 3
[0041] Example 3. The invention discloses a method for making bio-organic fertilizer by using municipal sludge. Wherein the time of aerobic fermentation is 11 days.
[0042] The mass formula for material preparation is as follows: 9.5% of urban sludge, 70% of pig manure, 13% of straw, 2% of compound decomposing bacteria agent, and the rest is fly ash, and then add water to adjust the water content to 60%.
[0043] The mass ratio of additives is: urea 7%, monoammonium sulfate 4%, phosphate rock powder 2%, potassium sulfate 4%, borax 0.4%, zinc sulfate 1.2%, magnesium sulfate 1.2%, manganese sulfate 1.2%, iron sulfate 1.2% % and 3% of clay, and the rest are pulverized materials.
[0044] The technological conditions of the solution treatment are: the speed of the high-pressure mixer is 58 rpm, the temperature is 35°C, the pressure is 0.15Mpa, and the solution time is 1.1 minutes.
[0045] All the other are with embodiment 1.
