description: The topic of the final qualifying work: "Improving the efficiency of the energy economy of the enterprise in the implementation of a closed resource cycle of liquid waste". The purpose of this work is to substantiate the implementation of a complex of organizational and technical solutions for the return of liquid waste from industrial enterprises to the resource cycle. The object of the study is the energy economy of the enterprise. The subject of the study is a closed resource cycle for the processing of liquid waste. Research methodology: theoretical analysis and generalization of scientific literature, analysis of the regulatory framework, system analysis, comparison methods, hierarchy analysis method. In the course of the work, an analysis of the regulatory and legal documentation on the treatment of liquid waste in the Russian Federation was carried out. Insufficient regulation of discharges into water bodies has been revealed, recommendations for improving the system of regulatory and legal documentation have been proposed. A study of world and domestic experience has shown the prospect of using a membrane bioreactor (MBR) at pulp and paper enterprises (CBP). To date, Russia has experience in using this technology only at oil refineries. The use of ICBMs at the CBP will allow to return 90% of water to the resource cycle, thereby increasing the efficiency of the energy economy of the enterprise. An economic and environmental assessment of the introduction of a membrane bioreactor at the Kotlas Pulp and Paper Enterprise was carried out. The analysis showing the potential of reducing the costs of the Kotlas cellulose and paper enterprise when using a membrane bioreactor is carried out. The implementation of measures to improve the treatment plant system will lead to an improvement in the economic and environmental situation in the region.
