The method for direction selection of activated sludge is developed, allowing receiving the silt possessing lowered, for removal technology of biogenic elements, sludge index (80...100 cm³/g) and higher deposition retrogradation. The possibility exists of increase the dose of activated sludge in the aeration tanks, projected by denitrification and phosphorus (from 2...3 to 4.5...6.5 g/l) due to the removal of the system of slowly settling silt fraction. At the current stage of working estimated the stability of the formed sludge in the ecological community for 1.2 years and by means of mathematical OxiD model the operating practice of effluent treatment in Moscow from ammonia nitrogen is defined. The OxiD model allows to solve real operational problems to stability augmentation of the quality of effluent treatment and to calculate the technological and design parameters of the aeration tanks, which will provide a programme quality of effluent water in the real dynamics of the input flow.
