摘要

The ocher pellets, called limnomedicine, that consist of ocher and calciumnitrate were used to suppress phosphorus release from contaminated sediment underanaerobic condition. The proposed model represents the fate and transport of nitratereleased from the pellets, both in water column and sediment. Most of nitrate (83.6%)released from the pellet was consumed for degradation of organic matter and FeS in thesediment for 12 days. An increase in the amount of pellet dosage has a good effectaccelerating sediment treatment rate, but produce a side effect of increased mass ofnitrate diffused out to the water column. Through quantitative analysis on these effectsusing the proposed mathematical model, we might determine the proper usage of pelletbased on sediment conditions such as organic matter contents.
