Characteristics of nitrogen and phosphorus loads in peat mining wastewater

摘要

Runoff water quality from a peat mine was studied during 1995 and 1996 in Central Finland. Water samples from three drained sub-catchments and groundwater were analysed for all the standard Physio-chemical parametres including different forms of nitrogen and phosphorus. The annual leaching of Phosphorus, nitrogen and suspended solids was estimated to be 16-38 kg km~-2, 1073-1500kg km~-2, and 2-8 t km~-2, respectively.
