BPBC处理苯酚废水的实验研究结果表明，苯酚的降解速率与酚浓度呈一级反应关系，即随着实际电解时间的增加苯酚降解速率逐渐减小；随着槽电压的增大，苯酚的去除率也随之增大，但是槽电压超过10V后，苯酚去除率增加趋势减缓；在碱性条件下，pH值的变化对苯酚的去除率有一定的影响，随着pH值的增大，去除率逐渐的降低；空床流速过大时，苯酚去除率有一定的下降；投加电解质后，苯酚的去除率增加，而就投加NaCl和NaNO_3的情况下，投加等摩尔浓度的NaCl和NaNO_3，投加NaCl的效果要优于投加NaNO_3的效果；提高废水中的溶解氧有利于苯酚的去除。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
