Beijing's upcoming heating season will see reclaimed water introduced into the heat supply system. The project uses centrifugal water-source heat pump units to extract thermal energy through contactless heat exchange with reclaimed water from the Qinghe Reclaimed Water Plant, without affecting water quality. Compared with conventional heating methods, this approach can save more than 30% of fossil energy and achieve zero carbon emissions. It will heat an area of 2.86 million square meters, saving over 30,000 tons of standard coal and reducing carbon emissions by more than 70,000 tons annually. By 2025, Beijing's reclaimed water utilization is expected to exceed 1.3 billion cubic meters, accounting for more than 30% of the city's total water supply. Going forward, the city will accelerate the construction of several key reclaimed water plants and effectively carry out the renewal and renovation of reclaimed water pipelines and sewage networks.
