Assessment the maximum-permissible impact on self-cleaning processes in the small waterway ecosystem

Criteria of choice the priority pollutant of eutrophic waterway on which transformation it is expedient to carry out an assessment of self-cleaning processes are given. Influence of various substances on processes of nitrification the ammonium nitrogen is considered and assessment of maximum-permissible loading on water object on inhibition the nitrification processes with use of a method of laboratory modeling is carried out.
