1. Introduction of Shanghai Zhuyuan Sewage Treatment Plant:
The first and second sewage treatment plants in Zhuyuan, Pudong New Area were constructed in 2017. The first and second sewage treatment plants in Zhuyuan, Pudong New Area, Shanghai adopted the more advanced sewage treatment process AAO + advection precipitation + high efficiency precipitation + deep bed sand filtration. The design scale is 2.2 million cubic meters/day, and the preliminary daily treatment scale reaches 2.2 million cubic meters/day. It is designed by Shanghai Urban Construction Design and Research Institute. The project investment is nearly 396088792 million yuan. The first and second sewage treatment in Zhuyuan The main content of the new part of the plant’s upgrading and renovation project: new construction of 2.2 million cubic meters/day of sewage pre-treatment facilities, including the new coarse grid and inlet pump room, water distribution well, aeration grit tank, AAO biological reaction tank, blower room, External sludge return pump room, sludge storage tank, sludge dewatering machine room and silo, dosing room and drug storehouse, biological deodorization facilities, general substation, high-level distribution room, etc. Construction scale: The scale of upgrading and transformation is 2.2 million cubic meters/day, including Zhuyuan** sewage treatment plant 1.7 million cubic meters/day and Zhuyuan*2 sewage treatment plant 500,000 cubic meters/day. The design scale of the project is 800,000 m3/d of sewage. The sewage treatment adopts AAO+ advection sedimentation+ high-efficiency sedimentation+ deep-bed sand filtration, which meets the **A discharge standard in GB18918-2002, and the newly added land is about 23 hectares. Project investment: 396088792 million yuan.
