英文摘要	［中文文摘］采用序批式活性污泥法(SBR)处理模拟淀粉废水,研究缺氧时间、曝气时间、温度、进水负荷对处理效果的影响.结果表明,SBR法在室温下就能高效地处理淀粉废水.对于淀粉浓度≤1.0g·L-1、CODcr≤1115mg·L-1的废水,单用完全曝气SBR法就能得到很好的去除效果;随着浓度增大,则需要设置缺氧段,以促进淀粉被水解酸化成小分子有机酸,但缺氧段的设置对CODcr的去除不明显,曝气反应对CODcr的去除起主导作用.缺氧段的长短应由废水性质来决定.用SBR法处理淀粉废水具有较好抗负荷冲击能力和系统稳定性,在进水淀粉浓度高达6.0g·L-1、CODcr达6690mg·L-1时,淀粉去除率为97.3%,CODcr去除率为94.0%,经过1个多月的运行,废水中淀粉去除率和CODcr去除率均保持稳定.［英文文摘］The effects of anoxia time , aeration time , temperature and the organic load on the t reatment of starch wastewater in SBR reactor were investigated by using synthetic starch wastewater. It is shown that starch wastewater could be efficiently t reated at room temperature. Aerobic phase alone was sufficient for starch removal when starch concent ration and CODcr were less than 1. 0 g·L - 1 , 1 150 mg·L - 1 , respectively. When in2 creasing the organic load , anoxic phase was required to degrade most of the starch into organic acid. It was also found that CODcr was hardly removed by the anoxic biodegradation , whereas CODcr was mostly eliminated in aerobic phase. Moreover , SBR process seemed more insensitive to load fluctuation. Starch and CODcr removal efficiency achieved 97.3% and 94.5% , respectively , when starch concent ration in influent reached 6. 0 g·L - 1 (CODcr : 6 690 mg·L - 1) . Both the starch and CODcr removal efficiency kept stable during over2one2month operation.; 国家自然科学基金(20076037)
