On October 18th, the country’s first sewage treatment plant with a leading demonstration effect—Yixing Urban Sewage Resource Concept Plant was officially completed and put into operation in the Environmental Science Park. , A smart and relaxed brain, a highland of technological growth, and a garden full of love" as the goal, to implement the international advanced concept of low-carbon and green.

The concept plant business is a major industry innovation initiated by the China Urban Sewage Treatment Concept Plant Expert Committee led by Academician Qu Jiuhui in 2013. After eight years of investigation and research, technical verification, and project implementation, the construction was completed in two years.

Academicians Qu Jiuhui and Ren Hongqiang of the Chinese Academy of Engineering, Professors Wang Kaijun and Yu Gang, School of Environment, Tsinghua University, Deputy Director Ke Bing, China Agenda 21 Management Center, Professor Yu Hanqing, Department of Environmental Science and Engineering, University of Science and Technology of China, North China Municipal Engineering Design Institute Co., Ltd. Company Chief Engineer Zheng Xingcan, Professor Li Ji of the School of Environmental and Civil Engineering of Jiangnan University and other 8 experts from the Expert Committee of China's Urban Sewage Treatment Concept Plant; Zhang Dingming, Member of the Party Group and Deputy General Manager of China Three Gorges Group, and Liu Yi, Dean of the School of Environment of Tsinghua University, etc. Representatives of universities and leading enterprises in the environmental field; Zhang Bo, Chief Engineer of the Ministry of Ecology and Environment, Director of the Department of Water Ecological Environment, Xia Bing, Deputy Director of the Jiangsu Provincial Department of Science and Technology, Qin Yadong, Deputy Director of the Jiangsu Provincial Department of Ecology and Environment, Party Committee of Jiangsu Environmental Protection Group Xu Feng, deputy secretary and general manager, and leaders of Yixing City Feng Xiaochun, Zhu Xufeng, Chu Hongbiao, and Pei Zhiliang attended the commissioning ceremony.

The Yixing Concept Factory adopts the "Trinity" ecological complex structure texture of a water purification center, an organic matter co-processing center, and a production-oriented R&D center. Aiming at actual production applications, Yixing Concept Factory has developed and further breakthroughs in the application of technical processes: new technology for primary sedimentation and fermentation, which can simultaneously realize carbon source supplementation and deep phosphorus removal; multi-point water intake and multi-stage A/O biochemical technology, Realize the effective use of carbon sources in sewage in the denitrification process; dry anaerobic fermentation technology can realize the synergy of high solid content (15%-35%) and a variety of complex materials under low energy consumption and high load conditions Oxygen digestion; produces high-quality, standardized, and modular large-scale equipment that can achieve energy saving and consumption reduction in the operation of sewage treatment plants; with the goal of sustainable technology leadership and practical innovation, the establishment of a thousand-ton production test line and real-time display of advanced sewage Processing technology provides accelerators and new scenarios for accelerating scientific and technological innovation; forming concept factory processes, construction and operation modes for different goals and needs, making the concept factory reproducible and extendable.

It is reported that the Yixing Concept Plant is the first sewage treatment plant to fully introduce the concept and pursuit of the concept plant, and is called the original version of the concept plant. The Yixing concept plant expands the demonstration sewage plant from the basic functions of pollutant reduction to urban energy plants, water source plants, and fertilizer plants, and then develops into a new type of environmental infrastructure that integrates with cities and villages in an all-round way and symbiosis with each other.
