Beijing is about to enter a new heating season, and reclaimed water will join the ranks of heat energy. The centrifugal water source heat pump unit operated by Beijing Beipai Clean Energy Investment Co., Ltd. departs at least 100,000 m³ of reclaimed water every day from the Qinghe Reclaimed Water Plant and extracts 5℃ temperature difference heat energy through “air insulation and heat transfer” to meet the heating needs of Dongsheng Science Park. It does not enter the heating pipes, does not affect water quality, and the return water temperature is about 10℃. Compared with traditional energy heating, the project saves more than 30% of fossil energy consumption and zero carbon emissions. The heating area is 2.86 million square meters, saving more than 30,000 tons of standard coal and reducing carbon emissions by more than 70,000 tons a year. Wang Zhe, deputy head of the reclaimed water section of the Beijing Drainage Management Service Center, said that in 2025, the amount of reclaimed water used will exceed 1.3 billion cubic meters, accounting for more than 30% of the city's total water supply; the next step will be to promote the construction of key reclaimed water plants such as Jiuxianqiao No. 2, reduce Hebei, and Taihu Lake, and carry out the renewal and transformation of reclaimed water pipelines and sewage networks.
