| 摘 要： | 为分析螺旋挤压式固液分离机、滚轴过滤固液分离机和卧式螺旋沉降离心机3种固液分离设备的性能,用这3种设备对猪场粪水进行固液分离,检测处理后的液体的固体悬浮物含量、COD(化学需氧量)、总氮总磷,并对处理成本等进行分析。结果表明,卧式螺旋沉降离心机处理的粪水固体悬浮物较少,COD值和总氮总磷含量较低;螺旋挤压式固液分离机和滚轴过滤固液分离机能耗较低;卧式螺旋沉降离心机的附加投入较小。综合分析后认为用卧式螺旋沉降离心机对猪场粪水进行初步处理较为合适。

Effect of Three Kinds of the Solid-liquid Separation Equipment on Piggery Wastes and Its Cost Comparison |
| |
| Abstract: | In this study,the performance of three kinds of solid-liquid separation equipments such as screw extrusion solidliquid separator,roller extrusion filter solid-liquid separator and horizontal scroll decanter centrifuge for piggery wastes were analyzed.The evaluation index included the content of suspended particles,COD (chemical oxygen demand),total nitrogen and total phosphorus in the liquid after treatment and the operation costs.The results showed that the horizontal scroll decanter centrifuge had the lowest content of suspended particles,COD,total nitrogen and total phosphorus values;screw extrusion solid-liquid separator and roller extrusion filter solid-liquid separator had less energy consumption;horizontal scroll decanter centrifuge had lower additional investment.It suggested that the horizontal scroll decanter centrifuge is more suitable for preliminary treatment of piggery wastes. |
