粉煤灰对垃圾填埋场黄土垫层的改性试验

通过击实、渗透试验得到粉煤灰改性-黄土的最佳配比为10%。对压实黄土和压实粉煤灰改性-黄土,分别用清水和渗滤液进行室内渗透试验,结果表明:渗滤液在压实粉煤灰改性黄土中的渗透系数≤1.0×10-7cm/s,在压实黄土中的渗透系数≤1.0×10-5cm/s,前者可作为填埋场防渗垫层,后者可作为填埋场防渗保护垫层。对COD、NH3-N的去除效果前者优于后者。     

不同温度下MESBR工艺和传统的SBR工艺对比试验研究

在不同温度下,研究了流化填料分格式SBR工艺(简称MESBR工艺)与传统的SBR工艺的COD去除率,有机物降解速率,脱氮效果和污泥沉降性能。结果表明:MESBR系统温度下降到5℃时,COD的去除率基本稳定在90%以上,比传统SBR系统高出15%左右;MESBR系统与传统SBR系统的温度系数θ分别为1.021和1.045。温度由20℃下降至5℃时,传统SBR系统的TN和NH3-N去除率分别降低26.5%和20%,而MESBR系统分别降低18.6%和11%。传统SBR系统SVI值随温度变化较大,当温度下降到5℃时SVI值达到234.8 mL/g,而MESBR系统的SVI值没有明显的变化,基本维持在120~130 mL/g。
