改性煤矸石吸附剂吸附工业废水氨氮、COD的实验研究

Experimental Study on the Adsorption of Ammonia Nitrogen and COD in Industrial Wastewater Using Modified Coal Gangue Adsorbent

为进一步探究煤矸石和焦化废水的有效处理方式,本次研究提出对煤矸石进行处理而后吸附工业焦化废水的方法,以实现煤矸石和工业废水的双重处理。通过制备改性煤矸石并将其用于吸附工业废水氨氮和COD后发现,其对工业废水中的氨氮和COD均具有较优的吸附效果,且在实际情况下的表现也较优,证明本次的研究路线具有较高的可行性。

In order to further explore effective treatment methods for coal gangue and coking wastewater,this study proposes a method of treating coal gangue and then adsorbing industrial coking wastewater,in order to achieve dual treatment of coal gangue and industrial wastewater.After preparing modified coal gangue and using it to adsorb ammonia nitrogen and COD in industrial wastewater,it was found that it has excellent adsorption effects on both ammonia nitrogen and COD in industrial wastewater,and its performance in practical situations is also excellent,proving the high feasibility of this research route.
