- Abstract
Today the number of individual wastewater treatment plants in the country is increasing. Popular are biological treatment, activated sludge-based operating units. There are almost no data on how the wastewater disposed of nitrogen compounds, especially in the cold (winter) period. The article analyzes the small domestic wastewater treatment plant AT-6 available in the main clean-up indicators (pH, T, SS, BOD7, nitrate nitrogen, nitrite nitrogen, ammonia nitrogen concentrations). The investigation period as the AT-6 type device treated wastewater in line with the general requirements of the natural environment, effluents (depending on the temperature, odor, pH, and SS, BOD7 concentrations). Nitrate nitrogen and nitrite nitrogen concentrations in the effluent of the device did not exceed the requirements into the natural environment effluents. Ammonium nitrogen concentration in the treated wastewater the entire study period exceeded requirements (5 m. / l) of the discharge into the natural environment. It should be more research during the cold months to confirm this.
