- 摘要:
- 廣東省茂名市某河道人工濕地工程處理規(guī)模為10 000 m3/d,進(jìn)水BOD5/COD值為0.3,可生化性好,采用接觸氧化+人工濕地工藝處理受污染河水。運(yùn)行結(jié)果表明,該工藝運(yùn)行穩(wěn)定,出水主要指標(biāo)達(dá)到《地表水環(huán)境質(zhì)量標(biāo)準(zhǔn)》(GB 3838—2002)Ⅴ類水標(biāo)準(zhǔn)(氨氮≤4.4 mg/L)。工程總投資為1 500萬(wàn)元,運(yùn)行及日常維護(hù)簡(jiǎn)單,年運(yùn)行費(fèi)用為190.81萬(wàn)元,運(yùn)行成本為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.
