Evaluation and mechanism of ammonia nitrogen removal using sediments from a malodorous river.

ABSTRACT: Malodorous rivers are among the major environmental problems of cities in developing countries. In addition to the unpleasant smell, the sediments of such rivers can act as a sink for pollutants. The excessive amount of ammonia nitrogen (NH₃-N) in rivers is the main factor that causes the malodour. Therefore, a suitable method is necessary for sediment disposition and NH₃-N removal in malodorous rivers. The sediment in a malodorous river (PS) in Beijing, China was selected and modified via calcination (PS-D), Na⁺ doping (PS-Na) and calcination-Na⁺ doping (PS-DNa). The NH₃-N removal efficiency using the four sediment materials was evaluated, and results indicated that the NH₃-N removal efficiency using the modified sediment m
