As the efficiency of biological wastewater treatment in activated sludge systems can be increased if powdered mineral materials are added, the work described here investigated the effect of powdered keramsite on activated sludge and wastewater treatment in a sequencing batch reactor on the laboratory scale. Specifically, experiments were carried out on two sequencing batch reactors, with the reference system being the classical SBR with conventional activated sludge, while the second system involved a K-SBR (Keramsite - Sequencing Batch Reactor) with powdered keramsite added with a view to enhancing the effectiveness of the activated sludge. The concentration of powdered keramsite in the latter reactor was maintained at 0.75 g/L. The results confirmed the greater efficiency of biological wastewater treatment processes where activated sludge was supported by the keramsite.
如果在活性污泥系统中添加粉末状矿物材料，可以提高生物废水处理的效率，因此这里描述的工作研究了粉末状陶粒对活性污泥和序批式反应器中废水处理的影响，该实验是在实验室规模下进行的。具体来说，实验在两个序批式反应器上进行，参考系统是传统活性污泥的经典 SBR，而第二个系统涉及添加粉末状陶粒的 K-SBR（陶粒-序批式反应器），目的是提高活性污泥的效果。后者反应器中粉末状陶粒的浓度保持在 0.75 g/L。结果证实，在活性污泥得到陶粒支持的情况下，生物废水处理过程的效率更高。
