  The paper presents the results of a study of parameters used for determining the amount of organic pollutants in wastewater flowing into a collective wastewater treatment plant with a population equivalent of about 120 000 PE. The plant constituted part of a sewage system. Assays were performed for biochemical oxygen demand (BOD5), chemical oxygen demand (CODCr), permanganete index (CODMn) and total organic carbon (TOC). In addition,...

  Nowadays more than 100 constructed wetlands are in operation in Poland. Most of them are one stage wetland systems with horizontal subsurface flow. Such constructed wetlands ensure efficient removal of organic matter (BOD5, CODCr) and suspended solids but efficiency of nitrogen compounds removal in many cases is insufficient.In the period from 1995 to 2003 measurements of removal of contaminations in 11 individual pilot household...
