Abstract

At present, mechanical, chemical, biochemical and physicochemical methods of cleaning are developed and efficiently used to protect water bodies from sewage pollution. The methods of biochemical wastewater purification from organic contaminants with the use of activated sludge have received the highest recognition. Getting of additional nutrients (nitrogen, phosphorus, potassium) and other trophic precursors into the aquatic ecosystem directly leads to immediate biohydrogenase reaction of increase in the number and biomass of the primary producers of organic matter. Chemical composition of water is an important criterion for water quality assessment. Therefore, the study of the dynamics of qualitative and quantitative chemical composition of water is a priority task in determining the efficiency of wastewater treatment in bioreactors.
