Announcement on Inquiry for Temporary Construction of Suixi Second Sewage Treatment Plant Expansion and Upgrading Project

We are now conducting an open inquiry for the temporary construction project of the expansion and upgrading of the Suixi Second Wastewater Treatment Plant. Bidders who meet the requirements are welcome to participate in the bidding.

1、 Project Name and Content

1. Project Name: Expansion and Upgrading Project of Weixi Second Wastewater Treatment Plant

2. Project location: Weixi Second Wastewater Treatment Plant

3. Tendering unit: Wancho Environmental Protection Co., Ltd;

4. Project scale: The land within the original factory wall of this project is 53398 square meters (80.09 acres), and the newly added land is 25257.69 square meters (37.88 acres). After completion, the land scale will reach 78655.69 square meters (117.95 acres), with a total project scale of 100000 m ³/d. The entire plant's tail water is discharged 60000 m ³/d, and the remaining tail water is directly reused after disinfection, with a reuse volume of 40000 m ³/d. The composition is as follows:

(1) Upgrading and renovation project: The design scale is 60000 m ³/d. Currently, the effluent from the secondary sedimentation tank of the first and second phases of the project converges into the middle lift pump room, and then uniformly lifts into the high-efficiency sedimentation tank, denitrification filter, and ozone oxidation tank. The effluent enters the reclaimed water reuse tank.

(2) Expansion project: Design capacity of 40000 m ³/d (including 15000 m3/d of chemical wastewater pretreatment, civil engineering implemented at a scale of 15000 m3/d, equipment installed in stages at a scale of 7500 m3/d). The main process adopts coarse grid and Jinshui pump room+fine grid aeration sedimentation tank+hydrolysis acidification tank+improved biochemical tank+high-efficiency sedimentation tank+denitrification filter tank+ozone oxidation tank. The tail water enters the reclaimed water tank, and the chemical wastewater is further treated by the main engineering biochemical system after Fenton oxidation and hydrolysis acidification.

(3) Supporting construction of blower room, power supply and distribution engineering, and outdoor overall system.
