<p>The innovation refers to wastewater treatment equipment. Its objective lies in the development of such treatment equipment, which would ensure a high level of treatment of polluted wastewater and could be applied for the treatment of all types of industrial and communal wastewater, which contains chemical admixtures, phenols, fats, oil and other substances. The proposed equipment consists of six basic units, where the first unit is designed for the hard particles separation from wastewater, at the same time separating also fats and oil from wastewater; the second unit deals with the separation of oil and fats from wastewater; the third unit cools the partially mechanically treated wastewater prior to the biological processing and nitrification; the fourth unit processes the partially treated wastewater biologically; the fifth unit deals with the sedimentation of the developed biological sludge and possible admixtures; in the sixth unit the treated wastewater leaks out through the infiltration system and is drained into the independent place, moreover, depending on the wastewater quantity and the level of its pollution, each unit can be supplemented with a corresponding functional unit.</p> |
