【摘要】 针对原水长距离输送建立了管道模型,研究了LPBR及PAC-LPBR的水质改善效果。结果表明:LPBR对氨氮、UV₂₅₄、COD_Mn、DOC、微量有机物均有一定的去除能力,但其效果不如采用粉末活性炭强化的PAC-LPBR反应器。当粉末活性炭投加量为17 mg/L、反应时间为8 h时,PAC-LPBR对氨氮、UV₂₅₄、COD_Mn、DOC的去除率比LPBR分别提高了14.3%、56.6%、34.6%、43.2%,对微量有机物的去除能力亦大大提升。采用生物预处理/PAC-LPBR组合工艺可进一步强化处理效果。更多还原

【Abstract】 A raw water delivery pipeline model was established to investigate the water quality improvement effect of LPBR and PAC-LPBR.The results indicated that LPBR could remove ammonia nitrogen,UV₂₅₄,COD_Mn,DOC and trace organic compounds,but its removal effect was not so good as that of PAC-LPBR.Compared with LPBR,the removal rates of ammonia nitrogen,UV₂₅₄,COD_Mn and DOC in PAC-LPBR with PAC dosage of 17 mg/L and reaction time of 8 h were increased by 14.3%,56.6%,34.6% and 43.2%,respectively.The removal rate of trace organic matter was also greatly promoted.The treatment effect could be enhanced using the combined process of biological pretreatment and PACLPBR.更多还原
