Abstract

Abstract

Sewage contains abundant heat energy. Recycling heat energy in sewage is an important research direction in the field of energy conservation. Sewage source heat pump technology is an important technical means for recycling sewage heat energy. However, the long-term operation of sewage source heat pump in sewage will cause its heat exchanger affected by corrosion and scaling, thereby reducing the conversion efficiency of sewage heat energy and the resource utilization rate of sewage treatment plants. Therefore, taking the water source heat pump heat exchanger of urban sewage treatment plant as the research object, the key water quality factors affecting its heat transfer performance are deeply explored, and the effect of protective measures taken under complex water quality conditions is comprehensively evaluated. This study provides a reference for solving the long-term pollution problems of water source heat pump heat exchanger in the sewage treatment process with high efficiency and low cost, helps achieve the goal of carbon neutralization operation of sewage treatment.
