Abstract

Effects of different amounts of pig slurry added in auxiliary materials on the composting efficiency were investigated for establishing an efficient composting technology to recycle huge amount of pig slurry in large-scale pig farms. Three treatments were arranged in the factory to investigate the effect of different amounts of pig slurry addition in the mixture of mushroom dregs, rice chaff and sawdust on the composting efficiency by monitoring the variations of physicochemical indexes including stack temperature, pH value, EC, C/N, moisture content, ammonium nitrogen, nitrate nitrogen, germination index, lignin content, cellulose content, hemicellulose content, water-soluble carbon content and nutrients during composting process. The highest composting temperature was observed in stack Z3 and its temperature dropped faster than stack Z1 and Z2 at the end of composting. The pH decreased at beginning and then increased during the composting. In the end, it dropped and reached stabilization stage. The C/N values of all treatments decreased gradually during the composting process. The ratio of the end C/N to the initial of stack Z3 was 0.59 indicating it was matured at the end of composting. The ammonium and nitrate content decreased and then increased gradually, respectively. The tyrosine and tryptophan like substances disappeared in Z2 and Z3, while the humic acids and fulvic acids became the main component of the DOM after composting. Compared to Z1 and Z2, Z3 showed a greater degradation rate of lignin, cellulose and hemicellulose during composting. Germination index of each treatment increased during composting process. At the end of composting, the germination indices of Z1, Z2 and Z3 were 72%, 84% and 101%, respectively. The organic matter of all treatments decreased while the total N, P and K increased during the composting process. The addition of pig slurry to the mixture of mushroom residue, rice hulls and sawdust led to effective high-temperature-composting, which could be a novel strategy to deal with the huge amount of pig slurry in pig farms.
