Key innovations
The innovative mud-water self-circulation cascade phosphorus and nitrogen removal process achieves intelligent and efficient alternating treatment in the integrated reactor through electromechanical integration and automatic control, significantly reducing costs and reaching the international leading level.
Potential economic benefits
This green technology product has significant cost advantages over traditional A2/O processes by significantly reducing floor space, initial investment and daily operating expenses. This will lead to higher economic returns, faster payback periods and stronger market competitiveness.
Potential climate benefits
The process significantly reduces operating energy consumption and costs through intelligent control and optimization design. Compared with traditional A2/O processes, this means less power consumption and directly reduces carbon emissions from power generation. At the same time, efficient phosphorus removal and denitrification can effectively reduce water pollution, indirectly maintain ecological carbon sink functions, and help carbon neutrality.

Solution details

Project Introduction:

This project is a key scientific and technological research project in Jiangsu Province during the 10th Five-Year Plan. After four years of research from small, pilot and demonstration projects, two types of mud-water self-circulation cascade phosphorus and nitrogen removal processes and equipment have been developed. Through electromechanical integration and automatic control technology, the alternation of time and space, as well as the self-circulation flow of sludge and mixed liquor, are realized in the integrated reactor. It has the characteristics of intelligent and efficient phosphorus and nitrogen removal, occupying an area of land, Both investment and operating costs are lower than traditional A2/O phosphorus and nitrogen removal processes.


Project advantages:

This project has two invention patents. On November 8, 2006, the expert group headed by Academician Qian Yi reached the international leading level.
