摘要：Surface run-off from developed urban territories, be it orderly disposed surface run-off or diffused surface run-off, is among the main sources of man-made pollution and degradation of urban water bodies lo-cated within the boundaries of Moscow. In the present-day context, the improvement of their ecological condition is possible only in case of im-plementation of measures aimed at the reduction of human-induced impact on water bodies, elimination of accumulated environmental damage, re-covery of their self-purification ability and groundwater protection against pollution. The authors give the results of the seasonal monitoring of sur-face run-off composition and the composition of sludge produced by the treatment facilities located on urban territories of different functional pur-pose. The studies proved the idea that the application of polymeric floccu-lants intensifies the process of dewatering the sludge produced by treat-ment facilities in different seasons. The criteria characterizing the main ef-ficiency indices for the selection of technological approaches and equip-ment, were developed based on generalized and summarized experience in seasonal observations and evaluation of process and hydraulic parameters of the operation of surface run-off treatment facilities.
