氧化沟的水力计算

HYDRAULIC CALCULATION OF OXIDATION DITCH

阐述了氧化沟进水流量、循环流量和断面平均流速的关系 ,分析了沟内平均流速所起的作用及调节方法 ;分析了提升水头与水头损失的关系 ,给出了它们的计算方法 ;对弯道导流板的作用进行了剖析 ,提出了导流板偏置可以减少导流板的数量 ,降低弯道摩阻 ,并可以避免弯道隔墙背流处的固体沉淀。

This paper expounds the relation between the inflow discharge,the circulating discharge and the average flow velocity of sections and analyses the function and modulatory way of the average flow velocity in the oxidation ditch,which includes the relation between the calculation way of lift head and the head loss.According to the dissection of the function of the diversion plate,the author puts forward that the offset of the diversion plate can reduce the quantity of it so as to cut down the bend friction and avoid the deposition of solids on the lee side of the bend partition.
