Problems solved by technology

The method of adopting landfill then exists to take up a large area, and can cause secondary pollution to groundwater after rotting; Incineration can produce a large amount of soot and waste residue, still can pollute environment; Long (30 days-180 days), destruction of organic matter, incomplete deodorization, complex process, large investment, poor environment and other disadvantages
In the methods disclosed by CN1077942A, CN1134925A, CN1137030A, and CN1137504A, the common defects that exist are all processed by fermentation
This method is through the action of physics and microorganisms, so the processing time is long

Embodiment 1

[0019] Example 1 of Fermentation-free Treatment of Decomposed Organic Wastes to Prepare Organic Fertilizers

[0020] 1. Acid hydrolysis

[0021] Take 20 parts of urban sludge or human, livestock and poultry manure or animal viscera and fur, or a mixture of any two or more of the above-mentioned substances, and add 20 parts to the acidification equipment, and add nitric acid solution, hydrochloric acid solution or phosphoric acid solution One or 2 parts of any two or more of the above-mentioned solutions are added to the acidification equipment, stirred and mixed to make them uniform, and after 5 minutes to 60 minutes, the high temperature (60°C-90°C) generated by the system will destroy the harmful substances in the material. The fungus and weed seeds are completely killed, the material is fully degraded, the unpleasant smell is completely decomposed and eliminated, and the water in the material evaporates by 40%-60%. At this time, the material is strongly acidic.

Embodiment 2

[0029] Example Two of Fermentation-free Treatment of Decomposed Organic Wastes to Prepare Organic Fertilizers

[0030] 1. Acid hydrolysis

[0031] Take 98 parts of urban sludge or human, livestock and poultry manure or animal viscera and fur, or a mixture of any two or more of the above-mentioned substances, and add them to the acidification equipment. One or 40 parts of a mixture of any two or more of the above-mentioned solutions is added to the acidification equipment, stirred and mixed to make it uniform, and after 5 minutes to 60 minutes, the high temperature (60°C-90°C) generated by the system will be harmful to the material. The fungus and weed seeds are completely killed, the material is fully degraded, the unpleasant smell is completely decomposed and eliminated, and the water in the material evaporates by 40%-60%. At this time, the material is strongly acidic.

[0039] Non-fermentation treatment of rotten organic waste to prepare organic fertilizer Example 3

[0040] 1. Acid hydrolysis

[0041] Take 50 parts of urban sludge or human, livestock and poultry manure or animal viscera and fur, or a mixture of any two or more of the above, and add 50 parts to the acidification equipment, and take nitric acid solution, hydrochloric acid solution or phosphoric acid solution. One or a mixture of any two or more of the above-mentioned solutions 20 is added to the acidification equipment, stirred and mixed to make it uniform, and after 5 minutes to 60 minutes, the high temperature (60°C-90°C) generated by the system will kill harmful bacteria in the material Insects and weed seeds are completely killed, the material is fully degraded, the unpleasant smell is completely decomposed and eliminated, and the water in the material evaporates by 40%-60%. At this time, the material is strongly acidic.

Abstract

Production of organic fertilizer by non-fermentation treatment is carried out by taking urban sludge or excrement of human and livestock or animal viscus or hair and skin or mixture, adding into acid splitting agent-nitric acid or hydrochloric acid or sulfuric acid or phosphoric acid or mixed solution, dewatering at high temperature, deodorizing, sterilizing, killing pests and weeds, degrading base raw materials, adding into neutralizer-ammonium bicarbonate or fused calcium-magnesium phosphate fertilizer or magnesium oxide or calcium oxide or mixtures, neutralization reacting, regulating pH value and drying to obtain products. It is simple and cheap, can increase granular structure and keep soil fertility.

Description

technical field [0001] The invention relates to a method for preparing organic fertilizer from rotten organic waste without fermentation, which belongs to the category of agricultural fertilizers. Background technique [0002] Organic fertilizer is a kind of fertilizer, which belongs to the category of soil fertilizer. Applied to crops, it has the characteristics of loosening the soil, increasing the aggregate structure, and maintaining fertility. The invention prepares the organic fertilizer with the rotten waste-urban sludge or manure, livestock and poultry feces, animal viscera and fur as basic raw materials. [0003] With the rapid increase of urban population and the increasing scale of aquaculture production, the disposal of urban garbage, sludge and a large amount of livestock and poultry excrement has become a new problem that needs to be solved urgently. Due to the high water content, large volume, and high treatment costs in these excrements, some farming owners ...
