城市开发区工业与生活混合污水处理设计——以四川省成都市某工业开发区为例

Research on Treatment of Domestic and Industrial Wastewater in Urban Industrial Development Zone——A case study in Chengdu of Sichuan Province

城市工业开发区建设时推荐我国工业规模化和产业结构升级的重要措施和手段。但随着而来的是各种各样的工业废水、生活污水汇聚,为城市污水处理厂设计和工艺选择提出了新的要求。文章以四川省成都市为例,生化处理部分采用改良A2/O工艺。结果表明,该工艺具有较好的除氮去磷效果,出水可稳定达到国家《城镇污水处理厂污染物排放标准》(GB18918-2002)一级标准的A标准,能够满足工业开发区工业和生活混合污水处理需求。

Aim Providing a solution that combats industrial and domestic wastewater existed in current industrial development zone.Methods Using biochemical treatment,fabrication processing of improved A2/O process.Results Water can reach Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant（GB18918-2002）,A level of first classical standard.Conclusion Improved A2/O technology has good effect on removing nitrogen and phosphoric,which can meet the demand of industrial and domestic wastewater existed treatment in industrial development zone.
