On January 10, 2020, the CPC Central Committee and the State Council solemnly held the 2019 National Science and technology award conference in the Great Hall of the people. Xi Jinping, Li Keqiang, Wang Huning, Han Zheng and other party and state leaders attended the conference and awarded prizes to the winning delegates. Xi Jinping presented the prize to the highest prize winner.


Nanjing Jiusi High Tech Co., Ltd.'s "membrane preparation, integration technology and application for zero discharge of pulping wastewater" won the "second prize of national science and Technology Progress Award" in 2019.

In view of the demand of industrial wastewater emission reduction, the research idea of "pulping wastewater can be exhausted by chemical production method" is proposed. A new process of zero discharge of membrane pulping wastewater, which combines efficient pretreatment, multi membrane integration technology and efficient evaporation crystallization, is invented. The preparation method of super hydrophilic special ultrafiltration membrane and the collaborative control technology of water softening and membrane pollution are developed It has become a large-scale production line of special ultrafiltration membrane, implemented the world's first set of zero discharge project of membrane pulping wastewater with a capacity of 40000 tons / day, which has solved the international problem of zero discharge treatment of pulping wastewater, turned industrial wastewater into purified water for resource utilization, and was selected into the national "12th Five Year Plan" scientific and Technological Innovation Exhibition, and became a model for solving social development problems with science and technology.


The relevant achievements have been popularized and applied in pulping and papermaking, fine chemical industry, salt chemical industry, pharmaceutical industry and other waste water resources. The cumulative emission reduction of wastewater is 130 million tons, and COD is more than 7000 tons. The environmental benefits are very significant; remarkable economic and social benefits are generated, and important contributions are made to the high-quality development of economy and society.
