Experimental Study on the Removal of Nitrobenzene in Groundwater by Ultrafiltration
In order to solve the pollution of groundwater caused by persistent organic contaminants, the removal efficiency and affecting factors of nitrobenzene removal from groundwater by using ultrafiltration technology was investigated. The experimental results indicate that the ultrafiltration system can work continuously for 68 hours when initial concentration is 85μg/L, and the nitrobenzene concentration of outflow is less than 17μg/L. Fe and Mn in groundwater have no significant impact on the removal efficiency, but the effect of initial nitrobenzene concentration of inflow is obvious. The continuous operation time decrease sharply from 68 to 14 hours when nitrobenzene concentration is 340 μg/L. 2％ CH3CH2OH has the best performance for cleaning the fouling caused by nitrobenzene. As an urgent treatment technology, ultrafiltration technology could guarantee the security of drinking water for people living in rural area.
