摘要:为了提高堆肥效率以及改进传统的堆肥方式,采用分层的堆置方式,以竹炭作为分隔材料,进行好氧堆肥实验,系统地分析了堆肥过程中常规理化特性的变化以及氮素损失情况。结果表明:木屑处理组(A)和竹炭处理组(B)中温度均经历了升温期、高温期以及降温期3个阶段,满足堆肥3阶段理论；以竹炭作为分层材料使高温期pH值降低至8.23,低于A组(8.98),而pH值的降低有利于控制氨气挥发；堆肥结束时,B组中DOC降解率为75.3%,明显高于A组(60.2%)。B组处理中氨气累积释放量为2 127.8 mg,小于A组的2 522.8 mg,可见竹炭作为堆体分隔材料对堆肥过程有机质的降解利用以及氨气挥发的控制均有一定的促进作用。

Abstract:To enhance composting efficiency and improve traditional composting method, composting of sewage sludge with bamboo biochar as layered material was investigated. Changes in physicochemical properties and nitrogen loss were analyzed. The results showed that three stages including mesophilic, thermophilic and cooling phases were observed in both sawdust treatment (A) and bamboo biochar layered treatment (B), which could meet the typical three-stages theory. During thermophilic stage, the pH value in the treatment with bamboo biochar as layered material decreased to 8.23 compared with treatment A of 8.98. This decrease of pH is helpful to controlling NH3 emission. At the ending stage of composting, the DOC degradation rate in treament B was 73.5%, which was significant higher than that of treatment A (60.2%). The cumulative ammonia emission of treatment B was 2 127.8 mg, which was lower that treatment A (2 522.8 mg). Concludely, using bamboo carbon as layered material is beneficial to degradation of organic matter and reduce ammonia emission during sewage sludge composting process.
