A new generation of sewage treatment technology accelerates the empowerment of the water industry

Modern sewage treatment equipment and intricate pipeline systems are operating in an orderly manner. In the treatment pools, the water sways gently, and bubbles can be vaguely seen rolling under the water surface. This is the scene after the sewage is initially treated. These sewage will eventually flow into Shatangyong with clear and pure water quality that meets the standards.

This is the sewage treatment plant of Sanshui Southern District Industrial Park, Foshan City, Guangdong Province, Yixin Water, where the new generation of sewage biological treatment technology-Beijing Control Speed ​​Granule Technology is showing its prowess.

With the rapid progress of science and technology and the increasing awareness of environmental protection, the traditional water industry is calling for technological innovation, management innovation and model innovation to improve the efficiency and quality of sewage treatment and achieve higher standards of sustainable development. The water industry will provide new momentum for the high-quality development of the industry by cultivating new quality productivity.

Yixin Water's sewage treatment plant in Sanshui Southern District Industrial Park, Foshan City, Guangdong Province has a designed daily treatment capacity of 50,000 cubic meters, mainly treating 70% of industrial sewage and 30% of domestic sewage. The first large-scale engineering application project of Beijing Enterprises Speed ​​Granules was launched in the sewage treatment plant in July 2022, with a treatment scale of 8,000 cubic meters per day, and has been operating stably to date.

Yixin Speed ​​Granules is a new technology product independently developed by Yixin Water based on the characteristics of China's low carbon-nitrogen ratio sewage quality and aerobic granular sludge technology.

In 1991, aerobic granular sludge (AGS) was first discovered. It is considered to be a special biological aggregate formed by microorganisms under the action of self-agglomeration. Compared with traditional activated sludge, AGS has the characteristics of dense structure, high biological retention, and multifunctional bacterial colonization, which has attracted widespread attention from researchers at home and abroad.

However, the concentration of organic matter in urban domestic sewage in my country is generally low, the carbon-nitrogen ratio of raw water in sewage treatment plants is low, and the water quality fluctuates greatly, which are not conducive to the stable operation of the AGS process. How to realize the engineering application of the AGS process is a technical problem that needs to be overcome in the field of sewage treatment.

To this end, Yixin Water officially launched a major scientific and technological research project on Yixin Speed ​​Granular Technology in 2018. After six years and the accumulation of hundreds of thousands of data, it finally successfully overcame cutting-edge technical difficulties such as rapid cultivation of aerobic granular sludge and long-term stable operation in low carbon-nitrogen ratio sewage engineering applications, and formed a number of core technical achievements.
Yixin Technology Professional Company, newly established by Yixin Water, hopes to link scientific and technological resources, transform scientific and technological products, realize scientific and technological value, build an innovation platform, and continuously incubate new technologies and new achievements in the water industry.

This technology has excellent sludge settling performance. While achieving high-standard removal of chemical oxygen demand, ammonia nitrogen, total nitrogen, and total phosphorus in sewage, energy consumption can be reduced by more than 20%, project land area can be reduced by 50%, construction period can be reduced by 2/3, and investment can be saved by more than 20%. It can be quickly applied in scenarios such as decentralized sewage, urban sewage, industrial park sewage, and point source industrial wastewater.

Today, Yixin Speed ​​Granular Technology has become a leading green technology product for pollution reduction and carbon reduction in sewage treatment with its advantages of high integration, high performance, land saving, and investment saving.

At the same time, the Yixin Speed ​​Granule modular prefabricated water plant, which integrates the concept of Yixin Speed ​​Granule and prefabricated water plant and can be quickly assembled on the project site, has also come into being. The prefabricated concept significantly improves the construction quality of sewage treatment plants, shortens the construction period, and reduces the impact of construction. The modular prefabricated sewage integrated system can achieve a more refined module design scheme from the process.

This is a major breakthrough from 0 to 1 achieved by my country based on the AGS process. Behind the major breakthrough of Yixin Speed ​​Granule technology is the solid and powerful technical research of scientific researchers. It is the integrated joint result of production, learning, research and application from laboratory to pilot to industrialization. It is the powerful green vitality and unlimited possibilities of the new quality productivity to empower the ecological environment industry.

Yixin Water Group will promote the innovation and upgrading of the environmental protection industry through scientific and technological innovation and high-quality development of the industry, so that the original "municipal infrastructure" will gradually develop into a safer, cleaner and greener guarantee in the field of life, and at the same time become a more critical means of production in the production field, the clean elements and green elements in the new quality productivity, and continuously improve the "green content" of the development of the environmental protection industry, forming a green productivity with Chinese characteristics.

The spark of innovation is constantly being stimulated, and the development of the water industry is being injected with continuous momentum.
