| 摘 要： | 考察了螺旋压榨式脱水机对污泥的脱水性能.结果表明:对于含水率为97.9%的消化污泥,在絮凝剂投配率为0.51%、螺杆转速为0.25 r/min的条件下,脱水后泥饼含水率最低可达70.3%、固形物回收率为98.89%、污泥处理量为24.84 kg/h;对于含水率为99.7%的剩余污泥,在絮凝剂投配率为0.94%、螺杆转速为0.75 r/min的条件下,脱水后泥饼含水率为82.5%、固形物回收率为92.46%、污泥处理量为8.64 kg/h.螺旋压榨式脱水机对污泥的处理效果较带式脱水机有很大提高. |
| 关 键 词： | 螺旋压榨式脱水机 污泥 脱水 絮凝剂 含水率 |

| Abstract: | The sludge dewatering performance of screw press dehydrator was investigated.The results show that for the digested sludge with moisture content of 97.9%,under the condition of flocculant dosing rate of 0.51% and screw speed of 0.25 r/min,the minimum cake moisture content after dewatering is 70.3%,the solid recovery is 98.89% and the sludge treatment capacity is 24.84 kg/h.For the excess sludge with moisture content of 99.7%,under the condition of flocculant dosage rate of 0.94% and screw speed of 0.75 r/mi... |
| Keywords: | screw press dehydrator sludge dewatering flocculant moisture content |
