正交试验法在河道底泥脱水调理剂筛选试验中的应用
Application of Orthogonal Test in Dewatering Conditioners Screening Test for Sediment Sludge
摘要
Abstract
Objective] The aim was to select dewatering conditioners efficiently.[Method] A control group(without conditioner) and two exper-imental groups(formula I and formulaⅡ) were included in this study.The experimental groups were orthogonal tests,with specific resistance of sludge (SRF) as the index,conditioner compositions as factors and dosages as levels.[Result] The optimal proportion in formula I was:activated carbon powder 0.034 0 g,fly ash 0.085 0 g,quicklime powder 0.034 0 g,polymeric aluminum ferric chloride 0.169 8 g,SRF 2.12 ×109 m/kg;the optimal proportion in formulaⅡwas:iron powder 0.014 8 g,sodium hyposulfite 0.040 0 g,chitin citric acid 0.014 8 g,SRF 5.37 ×1010 m/kg. [Conclusion] Orthogonal test can be used in sediment dewatering field,not only to select dewatering conditioners with good effect rapidly and ef-fectively,but also to optimize the proportions of conditioners,which is vital to practical production.关键词
