Problems solved by technology

[0002] At present, livestock and poultry manure is processed by composting and fermenting. This method has the disadvantages of 1) large area and high equipment costs; 2) long fermentation time and low production efficiency, 15 days of fermentation in summer and 30 days of fermentation in winter, or even longer; 3) The deodorization is not complete, and the sterilization is not clean; 4) The stacking smell is strong, the sewage damage is strong, and even sewage seeps into the ground, polluting the environment
[0003] At present, there is no method for the treatment of livestock and poultry manure with small footprint, short fermentation treatment time, thorough deodorization and sterilization, less odor, no sewage, and no environmental pollution.

Embodiment 1

[0031] The harmless treatment method of livestock and poultry manure is carried out according to the following steps:

[0032] 1) Add the dispersant to the dehydrated livestock and poultry manure and mix well to disperse the livestock and poultry manure;

[0033] 2) Add the dispersed livestock and poultry feces to the high-frequency corona ozone sterilization device for ozone treatment after stirring, and perform negative ion deodorization treatment in the ultra-low pressure negative ion sterilization and deodorization device to obtain harmless livestock and poultry manure;

[0034] The dispersant is a composition of polyacrylamide and straw powder in a mass ratio of 4:96;

[0035] The mass ratio of dispersant and dehydrated livestock and poultry manure is 8:100;

[0036] The ultra-low voltage means that the negative ion generating voltage is 200V.

Abstract

The invention relates to a harmless treatment method for livestock and poultry manure. The method is characterized by comprising the following steps that a dispersing agent is added into dehydrated livestock and poultry manure, and uniformly mixed to obtain dispersed livestock and poultry manure; and the dispersed livestock and poultry manure is sequentially subjected to high-frequency corona ozone disinfection and sterilization treatment and ultra-low-pressure negative ion sterilization and deodorization treatment, and harmless livestock and poultry manure is obtained.

Description

technical field [0001] The invention relates to a harmless treatment method for livestock and poultry manure. Background technique [0002] At present, livestock and poultry manure is processed through composting and fermentation. This method has 1) large area and high equipment costs; 2) long fermentation time and low production efficiency, 15 days of fermentation in summer and 30 days of fermentation in winter, or even longer; 3) The deodorization is not complete, and the sterilization is not clean; 4) The stacking smell is strong, the sewage damage is strong, and even sewage seeps into the ground, polluting the environment. [0003] At present, there is no method for treating livestock and poultry manure that occupies a small area, has short fermentation treatment time, complete deodorization and sterilization, less odor, no sewage, and no environmental pollution. Contents of the invention [0004] The invention provides a harmless treatment method for livestock and po...
