Problems solved by technology

[0007] However, most of the current experiments on the reduction of greenhouse gas emissions by compost additives are carried out in the laboratory or through small-scale simulation experiments, and there are few studies in actual production, and there are large differences in the experimental results obtained by different scholars, such as Liu et al. (Liu Jinshan, Xie Zubin, Liu Gang, et al. A holistic evaluation of CO 2 equivalent greenhouse gas emissions from compost reactors with aeration and calcium superphosphate addition[J].Journal of Resources and Ecology,2010,1(2):177-185.) The study found that adding 7.5% calcium superphosphate to the mixture of chicken manure, cow manure and wheat straw Superphosphate, the greenhouse gas emissions of its treatment increased slightly compared with the control

Abstract

The invention discloses a livestock and poultry manure composting additive and an application thereof. The livestock and poultry manure composting additive is a mixture formed by a mixture A formed byferrous sulfate and zeolite, calcium superphosphate, bacillus subtilis WJC11 and bacillus cereus WJC2 according to a mass ratio of (1-50):(30-50):1:1. The livestock and poultry manure composting additive is used under a conventional operation technology of composting, a composting yield can be guaranteed and composting quality is improved, and a greenhouse gas released in a composting process ispreferentially reduced, thereby pollution to the environment caused by gas release in the composting process is effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of solid waste recycling in environmental protection pollution control, and in particular relates to a low-carbon and environment-friendly livestock and poultry manure composting additive for reducing greenhouse gas emissions and an application thereof. Background technique [0002] In recent years, my country's animal husbandry has developed rapidly, and the scale, intensification, and mechanization are getting higher and higher. At the same time, the discharge of livestock and poultry manure has increased sharply, which has brought huge pressure and threats to the environment we depend on for survival. . According to the data of the National Bureau of Statistics in 2010: in 2009, the discharge of livestock and poultry manure (feces + urine) in China was 3.264 billion tons of fresh weight, which was 1.6 times the total industrial solid waste discharge in the same period (National Bureau of Statistics of the ...
