Process for preparing organic fertilizer by biological mud and grass refuse of papermaking plant

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...
