- Study on Operation Optimization of Sludge Dewatering in Large Scale Sludge Incineration Project
摘要:- 介绍了白龙港污水处理厂污泥处理处置二期工程离心脱水系统的工艺设计、设备参数和进泥参数校正情况，并以实际调试为依据，对影响离心脱水机出泥含水率的几个重要因子（药剂投加量、污泥进泥量、稀释水、主机转速）进行试验分析，同时进行离心机恒扭矩试验，得出恒扭矩设置数值和最佳辅机扭矩目标值，最终确定该型号离心脱水机的运行区间；在该运行区间内进行168 h性能考核试验，最终得出最佳运行参数和运行结果，对类似大型污泥脱水系统工艺运行具有参考意义。
Abstract:- The process design, equipment parameters and sludge feeding parameter correction of centrifugal dewatering system for sludge treatment and disposal phase Ⅱ project of Bailonggang sewage treatment plant are introduced. On the basis of practical commissioning, several key factors such as agent dosage, sludge inflow, dilution water, and main engine speed, which affect the water content of the sludge outflow from the centrifugal dehydrator are tested and analyzed. At the same time, the constant torque test of the centrifuge is carried out, and the setting value of constant torque and the target value of the best auxiliary machine torque are obtained. Finally, the operation range of this type of centrifugal dehydrator is determined. The 168 h performance test is carried out in the operation range, and the optimal operation parameters are obtained, which has reference significance for similar large sludge dewatering system process operation.
