Reagent Treatment of Domestic Wastewater in Arctic Settlements from Ammonium Ions
The problem of treatment and disposal of domestic wastewater is very relevant for remote small settlements in the Arctic. Biological purification, as a traditional method, is problematic in conditions of low temperatures and high flow irregularity of wastewater. The organic substances characterized by BOD, COD and nitrogen compounds, which can be harmful when poorly treated wastewater is discharged into water bodies, are particularly difficult to extract from the water. In the conditions of the deteriorating environmental situation around the world, effective methods of wastewater treatment are being sought. This study examines the method of physical and chemical treatment of domestic wastewater from the small Arctic settlements. The experiment is carried out according to the standard laboratory research methods. For the study, real wastewater from the septic tanks was taken. These water samples were similar in composition to wastewater from the remote northern settlements. Particular attention is paid to the purification of water from ammonium ions at a temperature of 5 ℃. It turned out that it was possible. It is possible to reduce the concentration of ammonium ion by 96% by using the chemical precipitation method in combination with preliminary coagulation, oxidation and filtration. In addition, the effectiveness of physical and chemical treatment does not depend much on the temperature of incoming wastewater.
