Abstract
The general properties of modern filtering materials of the new generation, such as natural zeolites, are considered. The aspects for the use of natural zeolites for the purification of surface sewage waters from highways are analyzed. It is determined that zeolites are an extremely promising natural raw material, which is characterized by high technological parameters and the absence of negative environmental conse quences in their widespread use. Mathematical models of aerobic and anaerobic biological treatment of surface sewage waters are presented. One of the ways to increase the efficiency of biological treatment is the intro duction of a biosorption method based on the joint biological and adsorption treatment of sewage waters in time and space. The simulation results made it possible to evaluate the adequacy of the mathematical models used to describe the dynamics of the purification of surface sewage waters from highways using natural zeolites in order to provide further recommendations and optimal control of sewage treatment plants during biological treatment. An improved mathematical model can be used to determine the quality of surface sewage waters from highways. As a result of experimental studies, the efficiency of using alternative filtering natural materi als has been determined. The introduction of new cleaning methods with the use of natural zeolites solves the problem of improving the technical level of roads, traffic safety and environmental performance.
