| 摘 要： | 通过管道实验和明渠实验模拟尾水输送过程,研究不同输送方案对尾水中COD、BOD5、SS、TN、氨氮、TP、DO、雌酮(E1)、辛基酚(OP)、壬基酚(4-n-NP)等指标的去除规律,为徐州市截污导流工程尾水输送方案的选取提供理论依据.结果表明:(1)除DO、TP和SS外,管道输送方案对其他指标的控制能力均优于明渠;管道输送过程中,除SS和TN外,污染物的浓度变化主要发生在0～48 h.(2)在选择管道输送方案的基础上,可以考虑在实际输送时提高流速,缩短尾水在管道中的停留时间. |

| Abstract: | The simulated experiment of tail-water transportation by pipeline and open channel were conducted to study the effect of different tail-water transportation programs on the COD,BOD5,SS,TN,NH+4-N,TP,DO,estrone(E1),octyl phenol(OP) and nonyl phenol(4-n-NP) removal.The finding would provide theoretical references for selecting the tail-water transportation programs in Xuzhou sewage interception and diversion project.The results showed that the pipeline transportation program was superior to open channel transportation programs in pollution control except DO,TP and SS.During the tail-water pipeline transportation process,the pollutant removal occurred mainly in 0-48 h besides SS and TN.Thus,it was a wise choice to increase the tail-water flow in pipeline so as to decrease the tail-water retention time. |
