一段式厌氧氨氧化技术处理养猪废水

Ammonia Removal from Swine Wastewater by Anammox

研究采用一段式厌氧氨氧化处理养猪废水的可行性,分析D0、pH、温度对脱氮效率的影响,以及在最佳DO、pH、温度时的容积负荷,并与硝化反硝化技术进行了比较。结果表明,厌氧氨氧化可用作养猪废水的脱氮工艺,最佳的控制参数:D0为0.8 mg/L.pH值为7.9-8.0温度为35℃、容积负荷为1.49 kg N/(m^(3)·d)。与硝化反硝化脱氮相比,一段式厌氧氨氧化节省占地和运行费用。

Studied on the feasibility of ammonia removal from swine wastewater by anammox,analyzed the ffeets of DO,pH and temperature on the denirification fficiency,volume load rate in case of the optimal DO,pH and temperature,compared with nitrifi-cation and denitification process.Anammox achieved a relatively high denitrification efficiency while DO is 0.8 mg/L,pH value is 7.9~8.1,temperature is 35℃,volume load rate 1.49 kg N/(m^(2)·d).Compared with nitrification and denitrification process,Anam-mox saving more footprint and operation cost.
