摘要

摘要: 在厌氧折流板反应器(ABR)不同进水流量(150~500 L/h)和不同污泥高度(0~45 mm)的组合工况下,利用激光粒子图像测速技术(PIV)研究了ABR第一隔室内部的液相流场特性,获得了反应器关键截面的液相流场数据。结果表明:在污泥高度为0 mm时,ABR降流区径向平均速度随进水流量的增加呈先下降后增加再下降趋势;污泥高度为15 mm时,轴向平均速度随进水流量的增加呈先下降后增长趋势;平均涡量随进水流量的增加呈逐渐增加趋势。升流区径向和轴向平均速度随进水流量呈波动趋势。降流区的返混程度随污泥高度的增加而增大,矢量速度高速区集中在降流区距进水口180~250 mm处。升流区涡核数量随污泥高度增加而增加,矢量速度高速区集中在下部0~20 mm处。

Abstract: Different influent flow rates of 150-500 L/h and different sludge heights of 0-45 mm were combined in anaerobic baffled reactor (ABR).The liquid phase flow characteristics in the first compartment of ABR were investigated by laser particle image velocimetry (PIV), and the liquid phase flow field of the critical section of the reactor obtained. The results showed that when the sludge height was 0 mm, the radial mean velocity of the ABR down-flow zone decreased first, then increased and finally decreased with the increase of inflow rate; when the sludge height was 15 mm, the axial mean velocity decreased first and then increased with the increase of inflow. The vorticity intensity increased gradually with the water inflow, and the radial and axial mean velocities fluctuated upward and downward with the increase of inflow. With the increase of sludge, the degree of back flow in the down-flow zone became larger. The high vector velocity area was concentrated on the 180-250 mm away from the inlet of the down-flow zone. The number of vortex cores increased with the increase of sludge height, and the high vector velocity area was concentrated on the lower part of 0-20 mm.
