- 摘要:
- 在长江大保护的背景下，江西省九江市两河全地下水质净化厂应运而生。作为江西省首座花园式概念全地下污水处理设施，设计规模3×104 m3/d，负责收集处理九江市濂溪区约10 km2范围内的生活生产污水，出水水质需达到地表水准Ⅳ类标准，尾水最终排入长江。该净化厂污水处理构筑物均位于地下，地上设计运行管理用房及构思巧妙的景观公园。污水处理采用预处理+Bardenpho活性污泥法+高密度沉淀+反硝化深床滤池工艺，通水后各项出水指标均稳定达标。
- Abstract:
- The Lianghe underground wastewater treatment plant in Jiujiang City, Jiangxi Province emerges in the context of the great protection of the Yangtze River. As the first garden-type conceptual full underground wastewater treatment plant in Jiangxi Province, the designed scale is 3×104 m3/d, the domestic sewage and production wastewater collection area is approximately 10 km2 covering Lianxi District of Jiujiang City, and the effluent is discharged into the Yangtze River after meeting the surface water quasi class Ⅳ standard. The treatment structures of the wastewater treatment plant are located underground, while the operation and management rooms and a well-conceived landscape park are on the ground. The treatment process consists of pretreatment process, Bardenpho activated sludge process, high density sedimentation tank and denitrification deep bed filter. After commissioning, all the indexes of the effluent have stably reached the discharge standard.
