Ponomarenko R. Increasing ecological safety of drinking water in the region in terms of surface contamination source

Dissertation is devoted to solving scientific problems increasing the environmental security of the region in terms of pollution of surface water sources by bringing the level of ionic impurities in water to the norms established SSanRandN 2.2.4-171-10. Established causes of deterioration of water quality Karachunivskoho reservoir, the estimation of the residual capacity of the existing technical solutions to drinking water. Based on the structuring of processes, development and combating environmental hazards reasonably need to introduce new technical solutions in the preparation of drinking water on tap Karachunivskomu complex. The expediency of application in the preparation of drinking water engineering solutions on a "coagulation with additional processing sodium carbonate - сationites - сalcination - anion" that allows for the improvement of environmental security in terms of pollution of surface sources of drinking water. A mathematical model of the formation of sediment soluble compounds provides prompt correction flow rate of heterogeneous reactions by adding water to the starting sodium carbonate stage coagulation process of drinking water. Experimentally proved that the water reservoir Karachunivskoho maximum destruction efficiency of stable complex compounds of calcium and excretion of them in solid phase, which provides rigidity to the salt content of the normative level, reached by water introduced in the initial stage of coagulation concentration of sodium carbonate in 700 mg / liter. The results of research implemented in the technical task of designing reconstruction Karachunivskoho plumbing industry. Estimated cost effectiveness of implementing the technical solutions of 5.01 million. a year.
