Nitrification recovery behavior by bio-accelerators in copper-inhibited activated sludge system.

Abstract

Copper (Cu) is a toxic heavy metal which can cause inhibitory effects on nitrification process in biological wastewater treatment systems. However, few studies have done to dose accelerators into Cu-inhibited activated sludge system to promote bioactivity recovery of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB). In this study, four… (More)
