Improvement of biological purification technology

Abstract

This article discusses the current state of the “Dasht” wastewater treatment plant in Karshi, the need for its reconstruction and improvement of biological treatment technologies. As a result of the increase in the population, the construction of new residential areas, industrial enterprises and social facilities, the volume of wastewater is increasing, which is exceeding the maximum capacity of the treatment facilities. Therefore, the issue of introducing biological treatment methods, environmentally safe disinfection of wastewater using high-water grasses (pistia, eichhornia, chlorella) and microorganisms is becoming increasingly important. The possibility of reusing wastewater through deep biological treatment - in industrial cooling systems, for agricultural irrigation - is analyzed. At the same time, the economic efficiency of using purified water in rice cultivation is taken into account. The article substantiates the principle of operation of biological water bodies, their advantages, their contribution to saving water resources and their role in preventing environmental pollution. The article discusses the issues of reconstruction of the aerator of the wastewater treatment plant of the Dasht station in the city of Karshi, improvement of the technology of biological treatment of wastewater and their reuse. The need to develop scientifically based measures to reconstruct the facility and increase its reliability was noted. The objectives, technology and advantages of biological treatment of wastewater, the prospects for cooling equipment at industrial enterprises, and the reuse of purified water for agricultural needs, which will significantly save clean drinking water and technical water, improve the environment, are presented in the article.
