摘　　要：《城镇水务2035年行业发展规划纲要》提出2035年娱乐类以上标准的城镇水体比例不低于80%。劣V类水源条件下,在生境和场地限制的城市中心建设旁路处理的水体净化工程,综合跌水曝气、气浮除藻、生物除氨、滤池降浊、光催化氧化除氨及消毒、次氯酸钠备用等处理工艺,构建生物浮滤池为核心的多级处理流程,主体工程置于地下,满足周边景观要求,巧妙实现工艺过程融合、竖向叠合和平面贴合,出水浑浊度小于1.0 NTU,氨氮去除率大于40%,达到高标准景观水要求。The Outline of 2035 Urban Water Industry Development Plan proposes that the proportion of urban water bodies with entertainment standards or above in 2035 can not be less than 80%.Under the condition of inferior class V water source,water bypass treatment project in the urban center limited by habitat and site,which main structure is placed underground to meet the requirements of surrounding landscape,integrates water drop aeration,air flotation algae removal,biological ammonia removal,filter turbidity reduction,photocatalytic oxidation ammonia removal and disinfection,sodium hypochlorite standby and other treatment processes,builds a multistage treatment process with biological floatation filter as the core,skillfully realizes the integration of process,vertical superposition and plane fitting.The effluent turbidity is less than 1.0 NTU,and the ammonia nitrogen removal rate is greater than 40%,meeting the requirements of high standard landscape water.
