The effects of the manure compost/coconut peels on the ammonia removal efficiency were examined from dairy manure composting mixed with crop residues. The high rapid composting and manure compost biofiltration experiments consisted of three biofilter vessels with one composter. Dairy manure amended with rice hulls and sawdust was composted in 605 L pilot-scale composter using continuous aeration for 19 days. Three pilot-scale manure compost biofilter amended with media bed 500 mm in depth and 300 mm in diameter were built to clean ammonia emission from composter, respectively. The manure compost biofilter media in the three experimental vessels was using a 50:50 by weight mixture of manure compost and coconut peels (MC/CP). The ammonia concentrations at the inlet and outlet biofilter media were measured by boric acid traps as described by Hong et al. [Hong, J.H., Keener, H.M., Elwell, D.L., 1998. Preliminary study of the effect of continuous and intermittent aeration on composting hog manure amended with sawdust. Compost Science and Utilization 6 (3), 74-88]. Results indicated that the mixture of MC/CP performed well as a biofilter media and the ammonia removal efficiency was 100% for the filter depth of 500 mm.
研究了粪肥堆肥/椰壳对奶牛粪便与作物残渣混合堆肥过程中氨去除效率的影响。高速堆肥和粪肥堆肥生物过滤实验由三个生物过滤容器和一个堆肥器组成。用稻壳和锯末改良的奶牛粪便在605升中试规模的堆肥器中进行连续曝气堆肥19天。建造了三个中试规模的粪肥堆肥生物过滤器,其介质床深度为500毫米,直径为300毫米,分别用于净化堆肥器排放的氨气。三个实验容器中的粪肥堆肥生物过滤介质采用粪肥堆肥和椰壳按重量比50:50的混合物(MC/CP)。按照Hong等人[Hong, J.H., Keener, H.M., Elwell, D.L., 1998. 连续和间歇曝气对用锯末改良的猪粪堆肥效果的初步研究。堆肥科学与利用6 (3), 74 - 88]所述,通过硼酸阱测量生物过滤介质进出口处的氨浓度。结果表明,MC/CP混合物作为生物过滤介质表现良好,对于500毫米的过滤深度,氨去除效率为100%。
