中文摘要：

利用序批式活性污泥反应器（SBR）研究了不同温度、溶解氧（DO）条件下的短程同步硝化反硝化（SND）过程特征及处理效果.本试验最佳温度控制范围在15～25℃,当DO在0.5～1.0 mg.L-1时,氨氮（NH4＋-N）去除率均在95%～98%,总氮（TN）去除率为85%～87%,化学需氧量（COD）的去除率达到90%～93%.试验结果表明：在一定的温度范围内,控制合适的DO,可以实现SND.

英文摘要：

Characteristics and treatment effect of simultaneous nitrification and denitrification（SND） were studied under different temperatures and DO in activated sludge sequencing batch reactor（SBR）.In the test,when shortened SND optimum temperature control range was 15~25 ℃and DO was 0.5~1.0 mg·L-1,the removal of NH＋4-N was 95%~98%,TN was 85%~87% and COD was 90%~93%.The results showed that it could implement shortened simultaneous nitrification and denitrification at right temperature and DO range.
