摘要(Abstract)：
针对目前国内污水处理搅拌池内流场测试研究空白,为研究污水处理搅拌机性能,选用NACA翼型,应用升力法对污水处理搅拌机叶片进行水力设计,并对搅拌池内流体流场分布进行试验研究。在设计的试验台上,利用流速仪,通过空间布点测量了污水搅拌池内不同位置的流体速度。利用EXCEL软件绘制了污水处理搅拌池内不同位置截面上的流体速度分布图,分析了池内流体速度分布规律。流体速度沿着轴向传递明显,流体径向扩散相对较小,且污水搅拌池内流体的流速基本沿污水处理搅拌机轴对称分布。试验表明:该测量方法可行,且该污水处理搅拌机具有明显的轴向导流和减少池壁边界对池内流体的影响作用。
For blank of the wastewater treatment flow field testing and to study the performance of wasterwater treatment mixer,blade was designed by using the lifting design method,and the velocity flow field distribution in the wasterwater mixing pool was experimental studied.On the test bed designed by ourselves,the fluid velocity at the different points of the pool was measured by using the velocity instrument.The velocity distribution graphes of the different section in the wastewater mixing pool were drawn by software EXCEL,and the velocity distribution rule was analyzed.The fluid flow obviously transfers along the axial direction of wastewater treatment mixer but little diffuses along the radial direction,and fluid velocity symmetrical along the mixer axis.The experimental results indicate that the wastewater treatment mixer can guide flow in axial direction,and it can reduce the effect of boundary of pool wall on the fluid in pool.
