- 摘要:
- 广东省茂名市某河道人工湿地工程处理规模为10 000 m3/d,进水BOD5/COD值为0.3,可生化性好,采用接触氧化+人工湿地工艺处理受污染河水。运行结果表明,该工艺运行稳定,出水主要指标达到《地表水环境质量标准》(GB 3838—2002)Ⅴ类水标准(氨氮≤4.4 mg/L)。工程总投资为1 500万元,运行及日常维护简单,年运行费用为190.81万元,运行成本为0.523 元/m3。
Abstract:- The treatment capacity of an ex-situ treatment constructed wetland in Maoming City in Guangdong Province was 10 000 m3/d, which was built for treating polluted river water. The influent BOD5/COD was 0.3, which meant that the river water had good biodegradability. The combined process of biological contact oxidation unit followed by constructed wetland was used to treat the polluted river water. The treatment performance of the treatment process was stable, and effluent quality could meet the class V criteria specified in the Environmental Quality Standards for Surface Water(GB 3838-2002)with ammonia nitrogen no more than 4.4 mg/L.The total investment was 15 million yuan, and the annual operating cost operating cost were both as low as 1.908 1 million yuan and 0.523 yuan/m3 due to the simple operation and maintenance.
