摘要
污水污泥样品经过105℃干燥处理后,在管式电阻炉和热天平上分别以15℃/min升温速率,在0～950℃温度范围进行污泥混合石英砂的热解实验研究。石英砂污泥混合热解实验发现:混合热解的产气总量得到提高,石英砂的加入不改变污泥热解生成可燃气的规律。在热解的高温段(800～950℃),由于加入了石英砂,CO浓度得到了提高。
The experimental sewage sludge samples were dried at 105℃,and pyrolysis of sewage sludge,quartz sand and sludge-quartz sand blends were studied by TG and fixed bed reactor at 15℃/min in the temperature range 0～950℃.The results showed that the gas generation could increase,but could not change the characteristics of the gas production and gas composition.In the pyrolysis temperature range of 800～950℃,CO concentration could be improved greatly because of quartz sand.
