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、UV_(254)、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、UV_(254)、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。
A raw water delivery pipeline model was established to investigate the water quality im- provement effect of LPBR and PAC-LPBR. The results indicated that LPBR could remove ammonia nitro- gen, UV254, CODMn, 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, UVz54, CODM, 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 PAC- LPBR.
