摘要
为探讨如何能快速形成好氧颗粒污泥,在不同的SBR反应器内分别加设网板直径为16cm和6cm,孔径为8mm,孔间距为1mm的水平网板,并在此基础上改变反应器的高径比(H/D),分析了网板及H/D对好氧颗粒污泥快速颗粒化的影响.试验结果表明:在反应器加设网板的条件下,H/D≥75∶7时可培养出好氧颗粒污泥,而H/D=1∶1时不能形成好氧颗粒污泥.
In order to investigate how to form aerobic granular sludge quickly,the intermittent flow method has been used in the experiment.The process which aerobic granular sludge is steadily fostered in Pore Plate of Plastic Sequencing Batch Reactor with different aspect ratio is studied in this paper.The paper also expounds the factor of reactor type（H/D） and affect that is caused by setting up Pore Plate of Plastic in the reactor when aerobic sludge granules form fast and steadily.The experimental results show that in the reactor under the condition of adding Pore Plate of Plastic,aerobic granular sludge can be fostered when H/D≥75∶7 but can not be fostered when H/D=1∶1.
