Production of organic fertilizer

Abstract

Production of organic fertilizer is carried out by charging, extracting materials from bins, delivering them into vacant bin, re-extracting materials from vacant bin, returning them to original bins, heating, discharging and separating. It's cheap, large scaled and has no environmental pollution. It utilizes animal and urban feces as raw material to produce by-product methane as agricultural fuel.

Description

technical field [0001] The invention relates to a method for preparing fertilizer, in particular to a method for preparing organic fertilizer. Background technique [0002] The development of rural breeding industry is a means for Chinese farmers to get rich. In rural China, modern large-scale breeding has developed rapidly, bringing benefits to farmers. But at the same time of development, it has also brought a large amount of livestock and poultry manure that is difficult to deal with. For example, a county in Shandong Province produces 7,000 tons of livestock and poultry manure every day, causing serious air and surface water pollution. In a place where pigs are concentrated in Hunan, the water source has been polluted by livestock and poultry feces, which has reached 10 meters underground, seriously affecting life. At present, the annual production of livestock and poultry manure in my country has reached 1.9 billion tons, which is more than twice the discharge of ind...

AI Technical Summary

Problems solved by technology

In the above method, there is still pollution to the air and surface water; in the process, a conditioning agent or regulator must be added, and the process is more and the production time is longer

In addition, in the above method, the mixing of materials is not easy, the temperature rise of the whole material is not easy to be consistent, and the product quality is difficult to improve, which cannot completely solve the problem of urban and rural human and animal manure treatment.
