摘要:- 介紹了白龍港污水處理廠污泥處理處置二期工程離心脫水系統(tǒng)的工藝設計、設備參數(shù)和進泥參數(shù)校正情況，并以實際調試為依據(jù)，對影響離心脫水機出泥含水率的幾個重要因子（藥劑投加量、污泥進泥量、稀釋水、主機轉速）進行試驗分析，同時進行離心機恒扭矩試驗，得出恒扭矩設置數(shù)值和最佳輔機扭矩目標值，最終確定該型號離心脫水機的運行區(qū)間；在該運行區(qū)間內進行168 h性能考核試驗，最終得出最佳運行參數(shù)和運行結果，對類似大型污泥脫水系統(tǒng)工藝運行具有參考意義。
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.
