THE STUDY OF SORPTION PROPERTIES OF SORBENTS USING FERRITE REAGENT DURING WASTEWATER TREATMENT
The article presents the results of studies of the sorption properties of natural sorbents using ferrite reagents on the example of poultry wastewater treatment. The studies were conducted at the department «Applied Geodesy, Environmental Engineering and Water Use» at the laboratory-experimental installation «Wastewater Treatment» in two stages. At the first stage, the sorption properties of various natural adsorbents were studied under static conditions to remove heavy metals and ammonium. At the second stage of research, the sedimentation was carried out already with a zeolite and the addition of a ferrite suspension for the purification of wastewater to the maximum permissible concentration of impurities in them. To assess the accuracy of the results obtained, an «Expert-003» photocolorimeter was used with the preparation of calibration solutions. According to the results of the research it was found that as a sorption load, natural zeolite showed the best absorption properties for the extraction of heavy metals and ammonium ions. According to the calculations, it became clear that the largest percentage of the absorption of impurities from wastewater is observed when using ferrite reagents and zeolite as a filtering load. The degree of extraction of contaminants, such as iron, copper, cadmium, and so on, was more than 90%. The use of this method will allow the use of treated wastewater for irrigation of agricultural crops, as a result of the effective work of the reagent-mechanical method of wastewater treatment, which meets all standards. The use of ferrite reagents and zeolite filter media in the complex is an effective technology for the removal of heavy metals and ammonium ions.
