- Abstract:
- The total long?term scale of a high?quality drinking water plant in Hebei Province is 35×104 m3/d, and the current scale is 19×104 m3/d, of which the scale of phase Ⅰ project is 15×104 m3/d, and the emergency expansion scale is 4×104 m3/d. The water sources are the main canal of the middle route of the South-to-North Water Diversion Project and the local reservoirs, which has the characteristics of high turbidity and high algae in summer and low temperature and low turbidity in winter. The waterworks adopts the combined treatment process consisting of enhanced conventional treatment process (coagulation, precipitation, filtration), ozone-activated carbon advanced treatment and combined disinfection process consisting of ultraviolet and chlorine dioxide disinfection. The total investment of the project is 802.00 million yuan, and the operating cost is 0.65 yuan/m3 (excluding the water resources charge). The turbidity in effluent from the waterworks is less than 0.30 NTU, the CODMn is less than 2.0 mg/L, and the water quality is better than the requirements specified in Standards for Drinking Water Quality (GB 5749-2006), and further meets the high-quality drinking water requirements specified in Water Quality Standards for Fine Drinking Water (CJ 94-2005).
