针对秸秆类废弃物厌氧发酵的速度慢以及常规的氨化预处理后物料氨氮含量高影响后续厌氧发酵的问题,提出鸡粪和稻秆混合物氨化预处理工艺,并在稻秆长度10 mm 及混合物 C/N 为25:1的条件下,研究氨化温度30℃和35℃对混合物TS降解率、VS降解率、氨氮含量和挥发性脂肪酸的影响。结果表明:鸡粪和稻秆混合物可以取得较好的氨化预处理效果,并可以实现TS 和 VS 的部分降解,而且氨化后产生的挥发性脂肪酸主要以乙酸为主;温度对鸡粪和稻秆混合物氨化预处理具有一定影响,30℃时的氨化预处理各指标均优于35℃。
針對秸稈類廢棄物厭氧髮酵的速度慢以及常規的氨化預處理後物料氨氮含量高影響後續厭氧髮酵的問題,提齣鷄糞和稻稈混閤物氨化預處理工藝,併在稻稈長度10 mm 及混閤物 C/N 為25:1的條件下,研究氨化溫度30℃和35℃對混閤物TS降解率、VS降解率、氨氮含量和揮髮性脂肪痠的影響。結果錶明:鷄糞和稻稈混閤物可以取得較好的氨化預處理效果,併可以實現TS 和 VS 的部分降解,而且氨化後產生的揮髮性脂肪痠主要以乙痠為主;溫度對鷄糞和稻稈混閤物氨化預處理具有一定影響,30℃時的氨化預處理各指標均優于35℃。

Ammoniation pretreatment technology of chicken manure and rice straw was put forward for the slow speed of anaerobic fermentation of straw waste and for the subsequent anaerobic fermentation influenced by materials still having high levels of ammonia nitrogen after conventional ammoniation pretreatment .The influences of ammoniation temperature at 30℃and 35℃respectively on TS degradation rate , VS degradation rate , ammonia nitrogen concentration and VFA of mixture were studied under the condition of rice straw length being 10 mm and mixture C/N being 25:1 .The results indi-cated that a better ammoniation pretreatment effect of chicken manure and rice straw could be achieved , TS and VS could be degraded partly and VFA generated after ammoniation was primarily acetic acid;ammoniation pretreatment of chicken manure and rice straw could be influenced by temperature to some degree and the indexes of ammoniation pretreatment at 30℃ were all superior to those at 35℃.
