Study of the imact of chemical plant wastewater on the adaptation of activated sludge at the municipal wastewater treatment facilities

Summary

The impact of diluted wastewater of a chemical plant on the biocenosis of microorganisms in activated sludge at the municipal wastewater treatment facilities is considered. In the course of studies, wastewater of Khimvolokno enterprise in Blagoveshchensk with known pollution concentrations was taken as a basis. Experiments were conducted to examine the impact of industrial wastewater on biological treatment, namely, in what proportions blending this wastewater with no harmful effect on the biocenosis of microorganisms is possible. Observations of the activated sludge show that at 1:50 dilution supplying wastewater with this ratio provides for slower inhibition of microorganisms than when supplying wastewater with a dilution of 1:10, 1:20, 1:30, 1:40. This wastewater can supplied to treatment facilities with gradual long-term adaptation of the biocenosis to it.

Key words
