The 3^rd Beijing College Students’ Social Practice and Science & Technology Contest of Energy and Water Conservation and Low Carbon Emission Reduction was held in the Daxing Campus of Beijing University of Civil Engineering and Architecture (BUCEA) on October 30^th. USTB submitted a total of 15 works, among which the work "Flue Gas Whitening Device Based on the Principle of Condensation and Reheating " supervised by Prof. ZHANG Peikun won the Grand Prize of the Contest. Three other works including " Waterless Toilet Based on Solar Energy Synergistic Pyrolysis Waste Heat for Energy Production of Fecal Biochar " won the first prize; three works including " Membrane Has a Solution --Efficient Penetrating Pharmaceutical Wastewater Degradation Device Based on Oriented Carbon Nanofiber Membrane " won the second prize, and six other works including " Low Temperature Plasma Exhaust Gas Purification Technology Based on Temperature Differential Power Generation " won the third prize. Prof. ZHANG Peikun, Prof. DUAN Xiaoli, Prof. WANG Qunhui and Prof. WANG Cunhai won the Outstanding Instructor Award; and USTB won the Outstanding Organization Award.

Since its launch in July 2021, the Contest has received enthusiastic response and participation from various universities, with 22 universities from Beijing participating, covering more than 1,600 students. A total of 242 works entered the preliminary evaluation and 101 works were selected for the final evaluation. In the end, 17 special awards, 35 first awards, 49 second awards and 57 third awards were selected.

The finalists' works covered two categories: social practice investigation reports and scientific and technological inventions, including 13 groups of subdivisions including energy saving, water saving, material saving, etc. To cope with the impact of the epidemic, this year's contest innovatively adopted the combination of "online + offline" evaluation method. Nearly 1,000 students participated in the online physical demonstration, group defense and other links. More than 30 evaluation experts from various universities and research institutions participated in the 10 evaluation rooms within the campus of BUCEA. Under the guidance of the instructors and evaluation experts, the participants carried out self-presentation and exchange of ideas. During the defense, the participants systematically elaborated the project background, core technology, innovative design, and development prospect of their works. The participating students closely combined their knowledge with the development of science and technology, social needs, and frontier topics, and produced a number of innovative and creative works, fully demonstrating the determination and strength of Beijing university students to devote themselves into science, technology, and innovation.

In order to meet the Contest with high quality, USTB attaches great importance to it and provided solid guarantee for the participating teams to exchange and discuss, produce works and carry out experiments.

The Contest is held once a year for college students in Beijing. The theme of this year's contest is to innovate " Environmental Energy” technology and draw the “Dual-Carbon” blueprint, focusing on green low-carbon, energy-saving and emission reduction related professional fields. It aims to implement ecological civilization, improve the scientific and technological innovation ability and practical education level of universities, and promote the construction of related disciplines such as environment and energy. It has made a promising impact on the mechanism of organizing the contest, students' participation and its function, and has become a grand event for college teachers and students to participate in the construction of ecological civilization and scientific and technological innovation.
