摘　　要：黄山风景区因水量和水质变化波动大、C/N比低、温差大、场地受限等特点,采用常规生化处理工艺难以达标排放。针对高山污水处理难点制定了提标改造方案,创新采用“气浮+Phoredox+高效沉淀池+精密转鼓过滤器+紫外消毒”工艺,辅以化学除P,并合理投加碳源,强化除磷和反硝化脱氮效果;同时针对游客量变化和冬季低温实行动态运维。工程自竣工投产运行以来稳定达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)中一级A标准,可为国内山岳景区污水处理工程的建设提供借鉴。Due to the large fluctuation of water quantity and quality,low C/N ratio,large temperature difference,limited site and other characteristics,it is difficult to ensure its discharge up to standard by using conventional biochemical treatment process in Huangshan mountains.Aiming at the difficulties of Alpine sewage treatment,the upgrading and transformation scheme was formulated,and the process of"air flotation+phoredox+high-efficiency sedimentation tank+precision drum filter+UV disinfection"was innovatively adopted.At the same time,the effects of denitrifying nitrogen and phosphorus removal were strengthened through chemical phosphorus removal and reasonable addition of carbon source.In addition,dynamic operation and maintenance shall be carried out according to the change of tourist volume and low temperature in winter.Since the project was completed and put into operation,it has stably reached the class I a standard in the Discharge Standard of Pollutants for Urban Sewage Treatment Plants(GB 18918-2002),which can provide reference for the construction of sewage treatment projects in domestic mountain scenic spots.
