Shandrovych V. Raising environmental safety through improvement of municipal wastewater treatment plants

The thesis is devoted to improving the environmental safety of urban sewage treatment plants. The analysis of the sources of environmental hazards municipal wastewater treatment plants and promising ways to minimize their environmental impact. Studies in laboratory efficiency of aeration at different initial concentrations of ammonia nitrogen and dissolved oxygen. Based on the data built the mathematical model of the process at various costs of waste water for various concentrations of ammonia nitrogen and dissolved oxygen. A long-term (320 days) experimental studies ANAMMOX process, to be able to implement it in urban wastewater treatment plants for treating highly concentrated ammonium wastewater generated after the stage of dehydration of waste sludge. The evaluation of the danger of surfactants and definite ability to biodegradable, the most popular of them. The possibility of cleaning filtrates solid waste landfills m. Lviv on urban wastewater treatment plants by mixing and subsequent purification of household waste arriving at them.
