САЖЕТАК / ABSTRACT:
As an important part of urban infrastructure, the stable operation and energy saving and emission reduction of underground wastewater treatment plants are of great significance to the sustainable development of cities. This paper discusses in depth the potential and practical path of underground wastewater treatment plants in terms of resilient, energy saving and low-carbon operation and maintenance. Through the investigation of the construction and development history and operation and maintenance of underground wastewater treatment plants at home and abroad, this paper analyzes and summarizes the problems such as operation and maintenance energy consumption, environmental pollution, comprehensive energy utilization, and intelligent monitoring of underground wastewater treatment plants, puts forward the resilience of underground wastewater treatment plants and low-carbon operation and maintenance ideas. Aiming at the problems of high energy consumption in operation and maintenance of underground wastewater treatment plants, difficulties in overhauling and odor treatment, etc., this paper carries out the research on the utilization of thermal energy of wastewater, refined intelligent control, and development and application of high-efficiency energy-saving equipment. Combined with different typical application cases, this paper explores the measures of low-carbon operation and maintenance management and intelligent monitoring system of underground wastewater treatment plants, explores the thermal energy, photovoltaic and reclaimed water utilization of wastewater, puts forward feasible and resilient operation and maintenance strategy and resource utilization scheme to realize cost reduction and efficiency which provide strong support for the sustainable development of the city. The research results of this paper provide an important reference value for guiding the resilient operation and maintenance of underground wastewater treatment plants and the application of low-carbon technologies.
