Essay

The dissertation is devoted to solving the scientific and applied problem of improving the environmental safety of wastewater infrastructure by developing scientific and methodological foundations of environmentally friendly technologies for phytoremediation of municipal wastewater in the context of post-war reconstruction of the state. The paper analyses the current state and prospects of innovative development of methods and technologies for improving the state of the aquatic environment. The concentrations of biogenic compounds in municipal wastewater were estimated. The choice of theoretical and experimental methods for studying the nutrient depletion in wastewater is substantiated. The metabolism of Ch. Vulgaris, Ch. Reinhardtii, O. Neglecta and E. Gracilis. According to the results of the study, it was found that the efficiency of nitrite (initial concentration 23 mg l-1), nitrate (initial concentration 9.3 mg l-1) and phosphate (initial concentration mg l-1 22.49) removal by Ch. Vulgaris was; 82.6%; 78.55%; 30.9%, respectively. According to the results of the study, it was found that the efficiency of N-NH4+ removal from synthetic wastewater with the participation of Ch. reinhardtii is 49-63 %, while P-PO43- is 6-18 % (depending on the initial concentration of nutrients). Thus, Ch. reinhardtii is, first of all, a promising microalgae species for the removal of ammonium nitrogen from wastewater. The culture of O. neglecta was sensitive to excessively high concentrations of N-NH4+ (90-140 mg l-1) and P-PO43- (26-90 mg l-1). Nevertheless, these microalgae are characterized by high functional activity, as well as high efficiency of removal of both ammonium nitrogen (60-61%) and phosphorus phosphate (43-55%) at initial concentrations of 30-50 mg l-1 and 7-14 mg l-1, respectively. It was found that Euglena gracilis is characterized by resistance to high concentrations of nitrogen and phosphorus. The ability of Euglena gracilis to almost completely remove ammonium nitrogen and phosphorus phosphate from the studied wastewater within 7 days was experimentally proved. Mathematical modelling of phytoremediation processes was performed. The peculiarities of using mathematical models of interaction between microalgae and biogenic pollution of the "predator-prey" type were investigated. Mathematical models of microalgae interaction with phosphates and nitrates were developed and tested, and the efficiency of microalgae use in the processes of phytoremediation of wastewater was evaluated. The thesis analyses current approaches to the organization of municipal infrastructure on the basis of environmental safety and identifies a number of problems associated with inefficiency, deterioration and obsolescence of municipal facilities. Based on a critical analysis of current approaches to the organization of municipal infrastructure, a conceptual model for the reconstruction of water treatment facilities on the basis of environmental sustainability is developed. The prospects for the development of phytoremediation technologies in the context of post-war reconstruction of the state are substantiated. Different designs of photobioreactors are analyzed and their own designs are proposed to increase the efficiency of biomass cultivation with simultaneous treatment of wastewater contaminated with nutrients. Methodological bases for decision-making in the preparation of organizational and technical measures for the restoration of wastewater infrastructure in the conditions of post-war reconstruction of the country on the basis of environmental safety have been developed. A system of target indicators has been formed, on the basis of which an organizational and target model and an algorithm for the implementation of organizational and technical measures for the restoration of wastewater infrastructure have been proposed. An organizational model for the introduction of the method of phytoremediation of wastewater into the technological process of treatment within the framework of infrastructure organization on the basis of environmental safety has been developed. A methodology for assessing the prospective level of environmental safety and the prospective results of environmental safety management of the restored infrastructure using the methods of pairwise comparisons and methods of expert evaluation is developed and proposed. A model of strategic management of infrastructure restoration is proposed, which determines the procedure for strategic planning of restoration, the procedure for assessing the prospective level of environmental safety of rebuilt or restored facilities, and the procedure for managing the environmental safety of restored infrastructure.
