- Abstract:
- The total design treatment capacity of the first surface water plant in a city of Shandong Province is 6×104 m3/d, and the treatment capacity of the first phase is 4×104 m3/d. The treatment process consists of pre-ozonation, mechanical mixing, grid flocculation, inclined tube sedimentation, ozonation, activated carbon filter, sand filter and NaClO disinfection. The process has several problems such as long process, few available footprints, incomplete plant area divided by municipal roads, which bring difficulties to process layout and passage of personnel. Therefore, intensive layout was adopted in the design. All the water treatment facilities were centralized in the comprehensive water purification room, and the sludge treatment facilities were centralized in the sludge treatment workshop. The design not only met the process treatment requirements, but also reduced the footprint and facilitated the management. Connecting different areas of the water plant through the underground passage not only met the needs of personnel and small tools/appliances passage, but also avoided the trouble of frequent passing through municipal roads. The operation practice showed that the treatment performance of the water plant was good, and all 106 water quality indices of the effluent met the requirements of Standards for Drinking Water Quality (GB 5749-2006).
