摘要： The present invention provides simple methods for treating aqueous chelating agent compositions containing one or more nitrilotriacetic acid (NTA) salts with one or more adsorbents, such as activated carbon, two or more activated carbon adsorbent in sequential treatments, to remove the NTA without removing more than 5 wt.%, or more than 3 wt.% or, preferably, more than 1 wt.% of the chelating agent in the aqueous chelating agent compositions. The methods comprise treating aqueous chelating agent compositions having a pH of from 7 to 12 and can be carried out at from 10 to 110 C. The methods can be used to treat a wide range of aqueous chelating agent compositions having, for example, from 700 to 6000 ppm of NTA, such as waste streams.

摘要：本发明公开了一种废旧电池放电处理高盐废水的方法和应用，该方法包括以下步骤：回收废旧锂电池，分离得到铝、铜、锰，将铝熔化，加入铜、锰，制成铝掺铜锰片，接入直流电稳压器的正极；将高盐废水过滤，再将接有铝掺铜锰片的正极、负极浸入高盐废水中，放电处理，过滤，得到硫酸盐废水。与现有技术相比，本发明利用废旧锂电池的电能处理高盐废水，既能达到废旧锂电池彻底放电的效果，又能除去高盐废水的NH 4 +、Na +、SO 4 2-、F -、碳酸脂类等物质，同时能间接地降低了成本。铝掺铜锰片是铝中加入铜、锰，加速铝电极电解，增加铝电极的自溶，加速铝离子处理废水，同时使铝不易钝化。
