温度对鸡粪和稻秆混合物氨化预处理的影响
Influence of Temperature on Ammoniation Pretreatment Characteristics of Chicken Manure and Rice Straw
摘要
Abstract
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℃.关键词
