摘要:
有效贮存新鲜水稻秸秆，确保沼气工程周年运行的原料供应,对于水稻秸秆厌氧发酵能源化利用技术持续健康发展极为重要。本研究以新鲜水稻秸秆及青贮后的水稻秸秆为原料,研究了其在室内中温[(37±2) ℃]条件下厌氧发酵产沼气特性。结果表明,水稻秸秆经青贮30 d后,秸秆pH降低至4.02,纤维素与总碳含量分别降低了6.39％和8.40％,均达显著水平。厌氧发酵30 d,青贮水稻秸秆产气量(3 370 ml)比新鲜秸秆(2 754 ml)显著提高22.36％。表明:青贮作为一项新鲜稻秸贮存与预处理方法,技术上是可行的,可确保沼气工程周年运行的原料供应。
Abstract:
It is important to conserve fresh rice straw effectively for sustainable resource supply for year-round biogas production. In this study, experiments were carried out evaluate the impacts of ensiling pretreatment on biogas production of rice straw at medium temperature [(37±2)℃]. Results showed that, after 30 d ensiling, pH value of the rice straw significantly dropped to 4.02, cellulose content was significantly decreased by 6.39％ and total carbon content was decreased by 8.40％, compared with un-ensiled rice straw. The anaerobically digested ensiled rice straw produced 3 370 ml biogas, 22.36％ greater than fresh rice straw. Ensiling is technically feasible as a conservation and pretreatment measure for fresh rice straw biogas production.
