中文摘要：
预处理条件选择是提高碳源碳释放性能的关键问题.本实验比较了未处理、酸处理、碱处理、高温蒸煮处理后,玉米秸秆的碳释放性能.结果表明,酸预处理、碱预处理和高温预处理均能起到明显破坏纤维素结构、释放有机质的作用.但是高温预处理质量损失较大,达到312.4mg·g-1,造成微生物可利用的碳源流失,降低了生物质碳源的使用周期.碱处理释放效果优于酸处理,10d内平均释放量达11.9mg·（g·d）-1.实验进一步比较了碱处理的预处理条件,结果表明,当碱浓度为2% NaOH、固液比为1∶10、浸泡时间为10h时释放效果较好.动力学试验表明,该预处理条件下,溶解性COD具有在12h内快速释放的特点,后期释放缓慢.
英文摘要：
The choice of pretreatment conditions was a key to improve the performance of carbon release. Experiment compared the carbon release properties of maize straw by untreated, acid treatment, alkali treatment and high temperature cooking treatment. The results showed that the acid pretreatment, alkali pretreatment and high temperature pretreatment could obviously destroyed the cellulose structure, released organic matter. But quality loss in high temperature pretreatment was larger and up to 312.4mg/g, could resulted in the loss of microbial available carbon source and the reduction of biomass carbon cycle. Effect of alkali treatment was better than the acid treatment, and the average release quantity was up to 11.9 mg/（g·d） in 10 days. Further experiments with the alkali treatment as pretreatment showed that when the alkali concentration, solid-liquid ratio and soaking time were 2% NaOH, 1：10, 10 h, release effect was better. The pretreatment conditions, dynamic test showed that the solubility of COD had the characteristics of quick release within 12h, the late released slowly.
