It is necessary to maintain and increase the capacity of water and land recycling and reuse systems, and to develop waste-free and resource-saving technologies. The problem of treating wastewater (leachate) from solid waste landfills is one of the most pressing issues of national importance. Such leachates from solid waste landfills pose a serious threat to the environment due to large-scale and uncontrolled pollution of groundwater and surface water. Today, in Ukraine, landfill leachate is usually not treated and flows into surface and groundwater without any treatment, causing enormous environmental damage. Therefore, the aim of this work is to study the process of ammonia blowing in order to obtain quantitative regularities necessary for further design of the relevant equipment and determine the required technological modes. The results of the work showed that increasing the pH of the filtrate during liming creates favourable conditions for ammonia blowing off at the pre-membrane treatment stage. It has also been shown that ammonia blowing under these conditions can reduce the concentration of ammonium nitrogen by 10 times or more, which makes it possible to bring its content in the filtrate to the standards for discharge into the sewer after further baromembrane treatment, as well as to obtain a valuable fertiliser by capturing it with acid in the form of ammonium nitrate or sulphate. Thus, it can be concluded that the proposed technological method is effective and economically justified for the treatment of landfill leachate. The results of the studies carried out in this work on laboratory equipment show the high efficiency of the application of the studied methods in the technology of water purification from ammonium compounds with subsequent recovery for the production of ammonium fertilisers. The theoretical regularities of the studied processes presented in this work make it possible, taking into account the minimum number of experimental measurements, to graphically determine the values required for further technological calculations, in particular, to determine the energy consumption of the relevant technological operations.

REMOVAL OF AMMONIA FROM SOLID WASTE LANDFILL WASTEWATER BY BLOWING |
| description |
An urgent task at the current level of society's development is to clean the environment from pollution caused by human activity. It is necessary to maintain and increase the capacity of water and land recycling and reuse systems, and to develop waste-free and resource-saving technologies.
The problem of treating wastewater (leachate) from solid waste landfills is one of the most pressing issues of national importance. Such leachates from solid waste landfills pose a serious threat to the environment due to large-scale and uncontrolled pollution of groundwater and surface water.
Today, in Ukraine, landfill leachate is usually not treated and flows into surface and groundwater without any treatment, causing enormous environmental damage.
Therefore, the aim of this work is to study the process of ammonia blowing in order to obtain quantitative regularities necessary for further design of the relevant equipment and determine the required technological modes.
The results of the work showed that increasing the pH of the filtrate during liming creates favourable conditions for ammonia blowing off at the pre-membrane treatment stage. It has also been shown that ammonia blowing under these conditions can reduce the concentration of ammonium nitrogen by 10 times or more, which makes it possible to bring its content in the filtrate to the standards for discharge into the sewer after further baromembrane treatment, as well as to obtain a valuable fertiliser by capturing it with acid in the form of ammonium nitrate or sulphate. Thus, it can be concluded that the proposed technological method is effective and economically justified for the treatment of landfill leachate.
The results of the studies carried out in this work on laboratory equipment show the high efficiency of the application of the studied methods in the technology of water purification from ammonium compounds with subsequent recovery for the production of ammonium fertilisers. The theoretical regularities of the studied processes presented in this work make it possible, taking into account the minimum number of experimental measurements, to graphically determine the values required for further technological calculations, in particular, to determine the energy consumption of the relevant technological operations. |
