- Abstract:
- Abstract：The design scale of Xinlong biomass high-performance fiber R & D platform and industrial water supply plant in Weifang is 5.0×104 m3/d. The designed water source is from the Xiashan reservoir derived from Yellow River, and the water quality meets the class Ⅲ criteria specified in Environmental Quality Standards for Surface Water（GB 3838-2002）. The product water of the water supply plant with turbidity below 1 NTU is used for production (chemical fiber) and fire fighting in the industrial park. The project has the characteristics of a small footprint area, low temperature and low turbidity of the raw water in winter and seasonal algae bloom occasionally. Therefore, the combined process of high-density sedimentation tank and D-type fiber filter was designed. Compared with the traditional process, the footprint area of this project decreased by about 50% through the optimization of the process design, “broken line” layout of the high-density sedimentation tank, application of new comet fiber filter and the ingenious combined construction of the structures.
