It is reported that the project has developed 3 key technologies including "Technology for Rapid Construction of Water Environment Technology Assessment Index Tree under Various Assessment Scenarios" in key links such as "technology assessment, secondary development, technology transaction, and industrial incubation". The National Eco-environmental Science and Technology Achievement Transformation Comprehensive Service Platform” has completed 17 technical assessments, 3 secondary development of technologies, 11 technical transactions, and 3 technical achievements incubation and transformation.

Tracing the source, this project was launched in December 2018, mainly to serve the construction of a green and ecological new urban area in Xiongan New Area. In addition, the water project also has a topic for the water environment of Baiyangdian Lake - "Research and Demonstration of Key Technologies for Water Ecological Environment Improvement and Water Safety Guarantee in Baiyangdian and Daqing River Basin (Xiongan New Area)". A major breakthrough has been made in this regard.

The project has developed 4 key technologies including "chemical pesticide process wastewater (wastewater from the production process of metazone)", and integrated 3 complete sets of technologies including "complete technology for recycling sodium chloride waste salt in fine chemical industry". Developed 3 complete sets of equipment including "simultaneous and continuous granular activated carbon adsorption/multi-stage regeneration equipment", and also compiled 3 technical specifications and 2 technical guidelines, and the harvest was full.

It is reported that 7 projects of its promotion and application have realized the harmless treatment of industrial wastewater of 40,000 m³/d, driving the related output value of more than 600 million, and solving the bottleneck problem of high-salt and high-concentration organic wastewater treatment that has long restricted enterprises.

The project has formed two complete sets of technologies for water ecological management and precise control of pollution sources, made breakthroughs in 14 key technologies, and compiled 26 guidelines, norms, standards, and guidelines to scientifically support the water environment protection and ecological restoration work in the Taihu Lake Basin.

It is worth mentioning that the issue of water environment governance in the Taihu Lake Basin has always received attention. Whether it is the research and conquering of its causes, or the complex technical research, as well as the large-scale demonstration application, the key motivation has been obtained from the special water project. The local government also mentioned in the feedback that the water project has achieved rich scientific research results in the Taihu Lake Basin. It is concentrated in three aspects:

①A number of technical achievements have been made in the control of nitrogen and phosphorus pollution in the river basin, river management, ecological restoration and prevention and control of cyanobacterial blooms;

② On the basis of intelligent supervision, build a precise and efficient water ecological environment management technology system in the Taihu Lake Basin;

③More than 200 project demonstration projects have been completed, and more than 100 standard specifications have been issued.

It is reported that Jiangsu Academy of Environmental Sciences, Nanjing University and other colleges and universities participated in the project, built a six-in-one Taihu Lake Basin environmental protection technology information exchange platform, and applied for 24 domestic patents. The total scale of 30 promotion and application processing exceeds 300,000 t/d, and the output value exceeds 500 million yuan.

The project integrates three technical process packages in the reduction and recycling of wastewater toxicity, deep denitrification and phosphorus removal of low-pollution water, and monitoring of water quality safety and water ecological health in sensitive waters. A number of new equipment and new material production bases such as biochemical tailwater multi-effect treatment chemical production lines.
