【摘要】 通过分析一体化氧化沟船式沉淀器在工艺运行中的特征,结合工程实例,对工艺实际运行中出现的船式沉淀器活性污泥沉降比下降、泥斗排泥不畅、出水堰“跑泥”等现象,应用水力学原理进行了分析。提出通过增加水力机械,增大船底水流速,进而增大船尾进水流速,并将船出水平流堰改进为梯形溢流堰等措施,提高船式沉淀器的处理效果。更多还原

【Abstract】 According to the technological characteristics of boat-type precipitator in an integrated oxidation ditch,the article discussed some phenomena that active sludge sedimentation rate descend and abnormal draining sludge in sludge funnel and "sludge flow" in drainage weir of precipitator,and analyzed the principium in hydraulics.The measures were indicated that increase waterpower machine and accretion water velocity of flow in boat bottom and tail,and laminose overfall drainage water become trapezia.更多还原
