Embodiment 1

[0053] 4 parts of grass residue, 3.5 parts of biochemical sludge, 1.5 parts of fly ash (fly ash of Jining Power Plant), 1 part of chicken manure, 0.007 parts of biological fermentation agent (Yian Shenli produced by Shandong Yian Bioengineering Co., Ltd. Brand CM composite microbial agent), make the moisture content of mixture at 55~60%, put in the fermenting pond of 1 meter below ground 0.7 meter in proportion, make material mix evenly, the width of fermenting pond is 8 meters. When the temperature of the material rises to 50°C, turn over and throw it. The fermentation tank is equipped with turning and throwing equipment, and then turn it over once a day; when the temperature of the material no longer rises significantly, after 7 to 12 days of fermentation, the fermented material can be taken out Dry to a moisture content of 15-30%. The fermented material is crushed by a chain crusher, passed through a 30-mesh sieve, and compounded with nitrogen, phosphorus, potassium and tra...

Embodiment 2

[0057] 4 parts of grass residue, 3.5 parts of biochemical sludge, 1.5 parts of fly ash (fly ash from Jining Power Plant), 1 part of chicken manure, 0.007 parts of biological fermentation bacteria agent (EM bacteria agent produced by Shandong Yian Bioengineering Co., Ltd.) , so that the moisture content of the mixture is 55-60%, put it into a fermenting tank 1 meter underground and 0.7 meters above the ground in proportion, and make the materials mix evenly as much as possible. The width of the fermenting tank is 8 meters. When the temperature of the material rises to 50°C, turn it over (the fermentation tank is equipped with a turning device), and then turn it over once a day; when the temperature of the material no longer rises significantly, after 7 to 12 days of fermentation, the fermented material can be Take it out and dry it until the moisture content is 15-30%. Use a chain crusher to crush the fermented materials, pass through a 40-mesh sieve, and crush the fertilizer n...

Embodiment 3

[0061] 4 parts of grass dregs, 3.5 parts of biochemical sludge, 1.5 parts of fly ash, 1 part of chicken manure, 0.007 parts of biological fermentation agent, so that the moisture content of the mixture is 55-60%. In the rice fermentation tank, the materials are mixed as evenly as possible, and the width of the fermentation tank is 8 meters. When the temperature of the material rises to 50°C, turn it over (the fermentation tank is equipped with a turning device), and then turn it over once a day; when the temperature of the material no longer rises significantly, after 7 to 12 days of fermentation, the fermented material can be Take it out and dry it until the moisture content is 15-30%. The fermented material is crushed with a chain crusher, and the fermented material is crushed through a 60-mesh sieve, and the fermented stock solution of compound phosphorus-solubilizing and potassium-solubilizing bacteria (Shandong Lihaoyuan Biological Engineering Co., Ltd. production), the ...

Abstract

The invention relates to a method of using biochemistry sludge and grass of paper mill to make organic fertilizer that belongs to organic fertilizer technology field. It contains 3-6 portions of grass, 3-5 portions of biochemistry sludge, 1-2 portions of fly ash, 1-2 portions of chicken manure, 0.005-0.01 portion of bio-fermentation agent, water content is 55%-60%. Putting the material into fermenting tank, after the temperature reaching to 50 degree centigrade, turning over, keeping fermenting for 7-12 days when the temperature altering not so obvious, drying the material, adding chemical fertilizer and microelement, normal organic fertilizer and organic inorganic mixture fertilizer would be gained. The invention is simple technology, and would stop the pollution to the environment from fertilizer.

Description

(1) Technical field [0001] The invention relates to a method for producing organic fertilizer by using industrial organic waste, in particular to a method for preparing organic fertilizer by using biochemical sludge and grass dregs in paper mills, and belongs to the technical field of organic fertilizer. (2) Background technology [0002] The amount of organic waste produced in my country ranks among the top in the world. Due to the low awareness of people for a long time, coupled with many factors such as backward technology and insufficient investment, the development and utilization of it is still relatively backward. At present, most of them are used in one-time utilization mode, with simple process, backward technology, low utilization rate, and limited processing capacity and utilization scale. With the development of the economy and the continuous improvement of people's awareness level, the agricultural utilization of waste will gradually develop in a large-scale, co...
