某经济开发区污水处理厂设计方案工程实例

Project Example of Design Proposal of Wastewater Treatment Plant in an Economic Development Zone

某经济开发区污水处理厂进水主要是生活污水和少量工业废水,采用预处理+多模式AAO工艺+絮凝沉淀池+活性砂滤池+紫外线消毒工艺,处理出水COD_(Cr)平均浓度为36.4mg/L,氨氮平均浓度为1.63 mg/L,其他指标也均能满足《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准。

A sewage treatment plant in an economic development zone, the influent of which is mainly domestic sewage and a small amount of industrial wastewater, using the pretreatment process ＋ multi-mode AAO processes and flocculation sedimentation tank ＋ continuous sand-filter ＋ UV disinfection process. Average effluent concentrations of C0DCr and ammonia nitrogen are 36. 4 mg/L and 1.63 mg/L respectively. Other indicators are also able to meet Urban Sewage Treatment Plant Pollutant Discharge Standardmulti-mode AAO processes continuous sand-filter design proposal（GB 18918-2002） ＂I-A＂ standard.
