Abstract
In the Russian Federation, the current standards oblige to carry out not only complete biological treatment of wastewater, but also their additional treatment. The main task of post-treatment technological processes is the removal of biogenic elements and some specific pollutants from water that has undergone biochemical treatment. Thus, the improvement of post-treatment remains an urgent environmental task, and the requirements for it can be defined as follows: ensuring the most complete removal of biogenic and other specific pollutants, including those contained in post-treatment wastewater in the form of colloids; ensuring the safety of discharges into water bodies by reducing the formation of carcinogens during disinfection; ensuring a high cleaning effect with increased instability of waste management conditions; ensuring technological simplicity and reliability of post-treatment devices; ensuring a reduction in the consumption of clean water for restoration work. This paper investigates a method for post-treatment of wastewater by a slow filmless filter with a vertical filtering surface. The properties of the slow filter cassette with respect to ammonium and phosphorus ions have been studied. The analysis of the integral kinetic curves is carried out. The efficiency of additional purification of wastewater from biogenic elements by a filmless slow filter for ammonium and phosphates has been investigated.
