Four different additives of Medical stone (MS), Zeolite (ZL), Bamboo biochar (BC), and Wood vinegar (WV) were investigated in pig manure composting. The four additives reduced the peak CH emission from 54% to 74%, while reduced NO loss from 36% to 69%, compared with control (CK). WV and ZL showed better ability in NO loss reduction, yet MS with the efficient inhibition both on CH and NH emissions. The bacterial community analysis indicated that bacterial diversity in the maturity phase was higher than that in the thermophilic phase, especially with treatments of ZL, BC and WV. The selected factors of pH, temperature, TOC and DOC could influence the thermophilic phase, while EC and TKN related closely with maturity phase in pig manure composting.
四种不同的添加剂(麦饭石、沸石、竹炭和木醋液)被应用于猪粪堆肥中。与对照组相比,这四种添加剂将 CH 排放峰值降低了 54%至 74%,同时将 NO 损失降低了 36%至 69%。WV 和 ZL 对减少 NO 损失的效果较好,而 MS 对 CH 和 NH 排放的抑制效果较好。细菌群落分析表明,在成熟阶段的细菌多样性高于在高温阶段,特别是在添加 ZL、BC 和 WV 的情况下。pH、温度、TOC 和 DOC 等选定因素会影响高温阶段,而 EC 和 TKN 则与猪粪堆肥的成熟阶段密切相关。
