EFFICIENCY OF WASTEWATER TREATMENT WITH WATER HYACINTH EICHORNIA CRASSIPES

Abstract

Prevention of pollution of effluents of water bodies and the environment in general, as well as surface water protection from pollution by untreated wastewater are priority tasks facing humanity today. To achieve an optimal solution, it is necessary to use new technologies or an effective combination of existing methods at operating sewage treatment plants. It has been established that a greater amount of wastewater occurs in the warm period of the year, respectively, and the load on treatment facilities increases. As a result of the analysis of data on wastewater composition indicators, it has been concluded that the concentrations of most pollutants increase during the warm period. Therefore, to improve the quality of purified water, it is proposed to use water hyacinth (Eichornia) together with reeds, which is used on operating biological ponds. This will make it possible to carry out additional wastewater treatment effectively, compensating for the lack of efficiency of treatment facilities. The paper presents the results of experimental studies of the higher aquatic plant Eichornii in vitro by helding a model experiment with subsequent implementation at the research object. The adaptability of water hyacinth to reservoir conditions, as well as to coastal and aquatic vegetation, have been studied. The results have proved the possibility of using reeds and Eichornia together at a wastewater treatment plant. The indicators of the qualitative composition of wastewater after treatment meet the requirements of SanPiN 2.1.3684-21.
