Embodiment 1

[0022] Example 1. The invention discloses a method for making bio-organic fertilizer by using municipal sludge. It includes the following steps:

[0023] (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;

[0024] (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;

[0025] (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

[0032] 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.

[0033] 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%.

[0034] 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.

[0035]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.

[0036] All the other are with embodiment 1.

Embodiment 3

[0037] 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.

[0038] 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%.

[0039] 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.

[0040] 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.

[0041] All the other are with embodiment 1.

Abstract

The invention relates to a method that uses city sludge to make biology organic fertilizer. It includes the following steps: mixing, dissolving, fermenting, smashing, adding additive, and fining and graining. The weight proportions of the raw material is that: (9-10)% city sludge, 65-70% swine waste or hen dung, (13-17)% stalk, (2-3)% compounding corrupting bacterium agent, and the other is fly ash, adjusting the water content to 55-65%. The additive is made up from 8% urea, 5% ammiaonia sulfate, 3% rock phosphate, 5%, 0.5%, 1%, 1%, 1%, %, 1%, 2.5%, and the other is smashed material.

Description

technical field [0001] The invention belongs to the technical field of fertilizer manufacture, and more specifically relates to the design of a method for making bio-organic fertilizer from urban sludge. Background technique [0002] With the continuous expansion of cities, there is currently no scientific, reasonable, and environmentally acceptable process for treating sludge after urban sewage treatment. Just take Qingdao Licunhe Sewage Treatment Plant as an example. The plant treats about 80,000 cubic meters of sewage every day, and the treated sludge is about 8 to 10 tons. At present, the sludge after the sewage treatment of the plant covers an area of ​​about 20 mu, and it is increasing day by day. There are 9 sewage treatment plants in Qingdao, which produce about 100,000 tons of municipal sludge every year. It is estimated that 300,000 tons of urban sludge will accumulate after 10 years. If the average height of the accumulation is 3 meters, it will occupy 200 mu of...
