Prospects for reducing the impact of phosphates on aquatic ecosystems

Abstract

The object of research is the pollution of aquatic ecosystems with phosphates. The subject of research is the reduction of the impact of phosphates on aquatic ecosystems due to the improvement of wastewater treatment systems. The aim of the work was to analyze the prospects for reducing water pollution by phosphates and their impact on aquatic ecosystems due to the improvement of wastewater treatment system. Research methods: analytical, chemical, statistical methods of data processing. Relevance. In recent years, the amount of phosphates in the wastewater entering the treatment facilities of the city of Kyiv - Bortnytsia aeration station, has increased significantly. To date, it reaches almost 30 mg / l, with a standard discharge 8.0 mg / l. At this concentration of phosphates in the incoming water, the old treatment technologies do not allow to reach the established norms for wastewater, which causes eutrophication and death of aquatic organisms. The solution to this problem is to improve wastewater treatment systems and limit the use of phosphorus-containing detergents. Scientific novelty: an analysis of ways to reduce the impact of phosphates on aquatic ecosystems. Practical significance: the results of the study are prepared for implementation in a comprehensive program aimed at protecting aquatic ecosystems and reducing the content of phosphates in water bodies of Ukraine. Personal contribution of the author: elaboration of scientific literature on the topic of work, analysis of data of the Institute of Hydrobiology of the National Academy of Sciences of Ukraine and Kyivvodokanal, preparation for the implementation of research results.
