Modern approaches to the treatment of various types of water (technological, wastewater, drinking) at thermal power plants
Keywords:
sorbents, water purification, thermal power plants, water treatment, petroleum products, waste waterAbstract
The article presents the types of new sorbents used in the industry from the point of view of their application for water purification for various purposes. A review of the literature and a selection of modern sorption materials of the new generation, which are raw materials of Russian production, for the purification of various types of water at thermal power plants to normalized indicators. Laboratory and industrial experiments were carried out to purify wastewater from petroleum products and drinking water from ammonium ions to normalized values using sorption materials APT-1, APT-2, APT-4 and BAU-A. At the Department of TOT of the MEI, work was carried out to study the properties of new sorption materials for the purification of technological, oil-containing wastewater and drinking-quality groundwater at thermal power plants. To determine the operability of sorbents for water purification from ammonium ions, a photocolorimetric analysis of filtrate samples was carried out. The sorption method of wastewater treatment is the most effective and environmentally acceptable method. A filter with a new sorbent should be installed as the last stage of purification of many types of water at thermal power plants to achieve the necessary water quality indicators: at a water purification plant from petroleum products; at a stormwater sewage treatment plant from petroleum products.
