摘要
针对氧化沟弯道水流流态复杂的特点,分析了弯道横向环流和水流流速在弯道重新分布对污泥沉积的影响,对设置偏置导流墙前后的水流流速分布情况进行模拟比较,探讨了偏置导流墙对减少污泥沉积的机理。
According to the complex flow regime of the return circuit of an oxidation ditch, it is analysed the effect of sludge deposition when transverse circulatory flow and velocity of flow are redistributed at the return circuit.It is simulated the velocity distribution before and after installing off-center training wall. It is also discussed the mechanism of reducing sludge deposition after installing off-center training wall.
