双锥型污水处理旋流器分离效果研究

为了检验新型污水处理系统设备的除油性能，设计建造了一套室内双锥型水力旋流器试验装置，并在该装置上进行了旋流器的外特性试验。以柴油作为介质，测量出了最佳流量范围、流量调节比和分流比等特性参数。实验结果表明，水力旋流器的压降随流量的增加而增大。在一定流量范围内，水力旋流器的分离效率不变。分流比大于１％ 时，旋流器的分离效率基本不变。入口浓度不影响旋流器的分离效率，但底流浓度随入口浓度的增大而增大

SEPARATION EFFICIENCY OF BICONICAL HYDROCYCLONE FOR WASTE WATER TREATMENT

An indoor hydraulic experimental device is designed to test de\|oiling capability of hydrocyclone. The external characteristics of a biconical hydrocyclone used for waste water treatment are studied on the device. Somecharacteristic parameters, such as the optimum range of flow rate, the turndown ration of flow and reject ratio, are measured with diesel oil as the experimental medium. The experimental results show that the pressure drop can be raised with increase of flow rate. The separation efficiency of the hydrocyclone does not change when the flow rate is in a special range or when the reject ratio exceeds 1%. The entrance concentration has no effect on the efficiency of hydrocyclone, but the underflow concentration escalates along with the augment of entrance concentration.
