In this article, biologically active tris-(2-hydroxyethyl) ammonium ionic liquids (IL) of the general formula [N(CH2CH2OH)3H]+ . –O(O)CCH2YAr (where Ar = aryl, Y = O, S, SO2) are studied as stimulators of biological wastewater treatment intensification (concentration is 10-4-10-8% mass). It was found that ionic liquids being introduced into the active sludge favorably influence the microorganisms of the activated sludge. When biostimulants are used, the biological wastewater treatment passes more intensively, and the indices of contaminantsm, such as ammonium ions and surfactants, decrease.
