The road to bidding for the largest sewage plant in Asia

Pudong Heqing Town, the expansion of the third phase of the Bailong Port Sewage Treatment Plant, the measurement and release work of main structures such as the pipeline renovation of the plant, the three links, the flat sinking sand pool, etc. are promoting.

The third phase of the expansion project is based on the current status of 2.8 million cubic meters per day of the current status of Bailong Port sewage treatment plant, and then expands 700,000 cubic meters/daily sewage treatment facilities and supporting sludge treatment facilities. On January 4, 2022, The construction of construction, planning to reach the standard in 2025, will help further solve the problem of overload operation of the Bailong Port sewage treatment plant, reduce pollutant emissions, improve the quality of the environment of the Yangtze River port, and implement the requirements of the Yangtze River protection and control of sewage overflow.

As the largest sewage treatment plant in Asia, the Bailong Port Sewage Treatment Plant is a major strategic decision -making result of the Shanghai Municipal Party Committee and Municipal Government. It is also another boutique project created by Shanghai Urban Investment.

At present, the Bailong Port Sewage Treatment Plant mainly accepts sewage in Xuhui, Jing'an, Huangpu, Wuyu, Minhang region and Minhang New District Zhaojiagou. The service area is 1,225 square kilometers. The processing scale is 2.8 million cubic meters per day, and the annual sewage volume is 1.1 billion tons.

As a key environmental protection project during the "Thirteenth Five -Year Plan" period in Shanghai, the Bailong Port Sewage Treatment Plant successfully implemented the second phase of the project and the second -phase project of the sludge treatment and disposal of the sludge treatment. The above emission standards, the annual COD reduction of 350,000 tons, accounting for about one -third of Shanghai's decreased displacement. The problem of water pollution control in the central urban area has been fundamentally solved. Complete the "Thirteenth Five -Year Plan" COD emission reduction task, and provides important guarantees to achieve the goal of harmlessness and reduction of sludge treatment. At the same time, it has significantly improved the overall environmental quality of Shanghai, greatly improved the regional water environment, and the regional water environment. Economic and social development is positive. As the last line of defense of the Yangtze River protection, it greatly improves the ecological environment of the Yangtze River mouth and achieves a win -win situation for environmental and social benefits.

It is worth mentioning that while carrying out the bidding and reconstruction project, the Bailong Port Sewage Treatment Plant also simultaneously improved the deodorizing system to improve the influence on the surrounding environment during the sewage treatment process. "". This is also the first time in China for more than 100 sewage sludge treatment facilities for large sewage plants, and tens of thousands of high -concentration odor release sources to implement a special rectification project for fully closed and full treatment. In the end, the total amount of odor is 42 million cubic meters per day, the cover area of ​​over 250,000 square meters, the collection of over 78.5 kilometers, and the new recycled water treatment and the self -cultivation of biological dewangbuishandiococcus suppliers. Completed and achieved the world's best in scale, and the standard has reached the highest domestic.

The Bailong Port Sewage Treatment Plant reflects the concept of independent innovation and energy conservation and environmental protection during engineering design and project construction management. The overall technology has reached the international advanced level. For example, the project adopts a multi -mode AAO nitrogen removal and phosphorus removal process to adapt to changes in different water quality, and at the same time, it can also improve the efficiency of treatment and water outlet. For another example, the project adopts a group intensive layout method, with a group of 400,000 cubic meters per day as a group. The first sinking pool, the AAO biological reaction pool, the second sinking pool, the return sludge pumping room of the return sludge, etc. Occupy.

After the third phase of the expansion of the Bailong Port Sewage Treatment Plant is completed, the Bailong Port Sewage Treatment Plant will become a world -class oversized sewage treatment plant of 3.5 million cubic meters per day, which will continue to rank first in Asia and further improve Shanghai. The sewage treatment capacity adds a strong stroke to the national "Yangtze River Protection" strategy.
