pretreated

Pretreated rice straws were degraded by cellulose degradation bacterium HIT-3. The degradation rate and reduced suger yield are 70.3% and 10.6%.

预处理后的稻草秸秆经过微生物降解，转化率可以达到70.3%，还原糖产率为10.6%。

Results ① The particle size and Ca 2+ relative concentration of the glass powder acid-pretreated decreased, but the superfacial area increased with rising acetic acid concentration and extending the length time of acid-pretreatment.

结果①随着醋酸浓度增大或处理时间延长，玻璃微粉粒径和表面Ca2+相对浓度减小、比表面积增大；

With locally preponderant duckweed after selection and alternanthera philoxeroides cultivated in single species and accrete system, performance on removal efficiency of nitrogen and phosphorus in municipal wastewater and diluted anaerobically pretreated wastewater from a cattle farm were investigated.

以经筛选得到的本地优势浮萍和水花生为研究对象，通过设置浮萍、水花生单种和浮萍-水花生混养等三种体系，考察了其对生活污水和稀释的牛场厌氧废水N、P的净化效果。
