摘要:
安康江南再生水厂采用半地下建设形式，设计规模为8×104 m3/d，近期设备按6×104 m3/d安装。为满足汉江50年一遇防洪要求，箱体入口高于防洪水位0.52 m。通过集约化设计，将综合楼、科普馆、臭氧发生间布置于箱体顶部，其余空间打造景观公园。污水处理采用改良AAO加悬浮填料、臭氧接触氧化主体工艺，出水主要指标达到了《地表水环境质量标准》（GB 3838—2002）Ⅳ类标准。污泥处理采用离心脱水+低温干化工艺，处理后污泥含水率≤60%。通水运行以来，实际出水水质稳定优于设计标准。
Abstract:
Ankang Jiangnan reclaimed water plant is a semi-underground plant. Its design scale is 8×104 m3/d, and the equipment is installed according to recent scale of 6×104 m3/d. The box entrance is 0.5 m higher than the flood control level to meet the flood control requirements of Hanjiang River 50-year return period. Through intensive design, the complex building, science museum and ozone generation room were arranged on the top of the box, and the rest space was built as a landscape park. The main treatment process consists of modified AAO with suspended carrier and ozone contact oxidation tank, and the main indicators of effluent meet the class Ⅳ limit specified in Environmental Quality Standards for Surface Water (GB 3838-2002). The sludge treatment process includes centrifugal dewatering and low temperature drying, and water content of the treated sludge is lower than 60%. Since the operation, the actual effluent quality is always better than the design standard.
