At the 2022 International Water Association (IWA) World Water Conference and exhibition held in the 2022 International Water Association in Danish Copenhagen, IWA Project Innovation Awards (PIA) were awarded by the School of Environmental Sciences and Engineering of Tongji University The team of professors is led, and the projects of Tongji University, Shanghai Municipal Engineering Design and Research Institute, Zhenjiang Water Industry Co., Ltd., Shanghai Tongzhdland Biomass Energy Co., Ltd., and Brenrek University of Technology in Germany "Based on collaboration and disgusting Oxigo -digestive municipal sludge and kitchen waste and other organic waste such as sustainable resource use treatment technology and model "won the international silver award. There are 6 categories in this project innovation award, each of which has one gold and silver and copper award. A total of 18 projects in the world have won awards, and 2 projects in China have won silver awards.

With the major support of national water pollution control and governance technology, the project team targets the problem of low and poor operating benefits of low organic matter sludge in my country, and the poor operating benefits of the lack of operation. It clarifies the ammonia/salt/organic acid suppression and relief mechanism of organic waste such as sludge and dining and kitchen, identifies key regulatory parameters for strengthening the coordinated digestion of sludge and organic waste, and developed a sludge based on multi -agency compatibility models With organic waste coordinated anaerobic digestive regulation technology, without increasing pool capacity, the sludge digestive facilities can be treated at the same time, and the kitchen waste can be treated at the same time. The lack of acidification of kitchen waste is significantly improved, significantly improved the comprehensive effectiveness of anaerobic digestion. This technology has successfully realized engineering applications in Zhenjiang, Jiangsu. After being purified by natural gas generated by the creatures, biogas dregs are used for urban greening and soil. The "Zhenjiang Model" of Land and City Organic Organic Qigate-Land Use, and achieves promotion and application in Zhenjiang Phase II, Jiujiang, Liu'an and other places, playing a good role in demonstration and leading. benefit. In addition, the coordinated treatment of kitchen waste and life sludge has a negative carbon emissions effect, which is of great significance for achieving the carbon emission reduction in the sewage treatment industry.

The International Water Association's Project Innovation Award (PIA) aims to recognize outstanding contributions and significant innovations in water technology, management, research and technology in global water technology, management, research, and technology. Make contribution.

Professor Kala Vairavamoorthy, Executive Chairman of the International Water Association, positively evaluated the scientific and technological innovation exploration practice of Tongji University. He said that the implementation of the project solves the problem of sludge the sludge of the sewage treatment plant, improves the living environment of cities and residents, and provides new ways to resource treatment and safety disposal for organic waste such as urban kitchen waste. The recycling and low -carbon development of China's sewage treatment industry has important inspiration and reference significance.
