| 摘要 |
<p>The present invention relates to a method for treating wastewater comprising adding a peracid to such wastewater after such wastewater has undergone a filtration step, characterized in that said peracid is added to said wastewater at a first peracid addition point; as well as at one or more subsequent peracid addition point(s) placed at sequential location(s) in a contact chamber. It has been unexpectedly found that such sequential addition is more effective than adding such peracid at a single location.</p> |
