Hygienic evaluation of effectiveness of drinking water purification facilities in Saratov institutions of social significance

Abstract

The purpose of the given work was studying of overall performance of the local equipments on water treating, both on superficial, and on underground sources of water supply. Material and metods. In research 60 assays of water from various superficial, underground reservoirs and planting system of water supply of the Saratov region have been selected and 900 definitions of the maintenance of chemical substances are spent. Results. Priority pollutants of underground waters in the Saratov and Fedorovsky districts of the Saratov region, it are established: rigidity salts, iron. For superficial sources of the same districts of area it: iron, manganese, Phenolum, Natrii phosphases. Water of open reservoirs also didn»t satisfy on organoleptic indicators and indicators of processes of self-cleaning. Efficiency of water-purifying constructions of Fedorovsky district, has appeared low. Water from underground sources got to the consumer without passage through water-purifying constructions. The conclusion: 1) water of underground and superficial reservoirs of rural settlements of the Saratov region has adverse organoleptic indicators and contains chemical pollution in the concentration exceeding maximum permissible; 2) efficiency of rural water-purifying constructions doesn»t allow to spend water treating according to SanPiN 2.1.4.1074-01; 3) application of the local equipments on potable water clearing has allowed to achieve reception on an exit from them the quality corresponding to demands SanPiN 2.1.4.1074-01.
