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.
