Kornienko I. Protection of water objects from biogenous elements and suspended substances (on the example of Dniprodzerzhinsk)

Subject of the research work: protection of water objects against the pollution with returnable waters (in area of Dneprodzerzhinsk). Purpose: to define ecological consequences of pollution of the river Dnepr with waste waters and develop technical decisions concerning normalization of quality of the returnable waters on nitrogen ammonium, phosphates and the measured substances according to the limits of MCL (on the example of Dneprodzerzhinsk). Methods: photometric, gravimetric, titrimetric, atomic and absorption. Theoretical and practical results: dependences of nitrogen ammonium and phosphates concentration in returnable waters on the content of fulfilled silt, dead seaweed and doze of active silt has been theoretically proved. The advanced technology of waste water clearing has been developed. Innovation: the role of Herpobdella octoculata, Asellus aquaticus in the process of returnable water cleaning has been defined. Degree of introduction: the results of the research work are partiallyintroduced at "Dneprodzerzhinskvodocanal". Due to this nitrogen ammonium and measured substances concentration has been normalized according to the norms of maximum concentration limit. Area of use: organizations that deal with of cleaning constructions municipal enterprises.
