- Abstract:
- The Wuhan Huangxiao River combined sewer overflow (CSO) enhanced treatment facility with intermittent operation mode is applied to treat the combined sewer overflow collected at the beginning of Huangxiao River open channel in the rainy season. The design scale of the facility is 6 m3/s. It adopts physical?chemical wastewater treatment processes such as fine grid, aerated grit chamber, high efficient sedimentation tank, precision filtration equipment, ultraviolet disinfection, and a belt thickening and dewatering machine which can efficiently deal with inorganic sludge is selected to reduce the excess sludge in the plant. In the design scheme, the operation and maintenance requirements under intermittent operation mode were fully considered, and special designs such as self-circulation of the effluent from the high efficient sedimentation tank and venting for the operation and maintenance convenience of the whole plant facilities were carried out. The tail water in the plant was recycled to save water resources and reduce the operating cost. The odor of odorous monomer was treated by ion deodorization process and emitted after reaching the emission standard. In addition, the high?standard greening design such as roof garden was adopted, making the project environment-friendly.
