Test Study on Simultaneous Ozonation Sludge Reduction

  • 摘要: 通过模拟某污水处理站的序批式活性污泥法(SBR)工艺运行条件,对其污泥混合液参数的变化规律进行了试验研究。结果表明:随着原位臭氧投加量的不断增加,SBR的混合液悬浮固体浓度(MLSS)和混合液挥发性悬浮固体浓度(MLVSS)呈下降趋势,污泥活性明显降低;臭氧氧化作用对污泥微生物细胞的破解可以引起污泥混合液中溶解性化学需氧量(SCOD)、总有机碳(TOC)、总氮(TN)和总磷(TP)浓度的升高,其最高值分别可达到1 366.5 mg/L、420.50 mg/L、31.89 mg/L和19.54 mg/L。污泥混合液中的氨氮(NH4+-N)浓度和pH值均呈下降的趋势,硝酸盐氮(NO3--N)浓度和亚硝酸盐氮(NO2--N)浓度表现为增加的规律,但NO2--N浓度随着臭氧量的继续投加呈现出下降的趋势。
