核基地污水生物处理技术分析

Analysis of Biological Treatment of Sewage in Nuclear Base

为评价生物接触氧化兼活性污泥技术对大亚湾核基地生活污水的处理效果,对2015-2016年基地内多处生活生产污水处理厂的进出口COD_(cr)、BOD_5、SS、NH_3-N和TP这五个监测指标含量的分析。结果表明,该处理技术对生活污水的废水COD_(cr)、BOD_5、SS、NH_3-N和TP的季度平均去除率分别为97.9%、99.5%、93.2%、97.6%、97.2%,八个污水处理厂的废水处理工艺符合环保及农用要求,对环境没有造成污染,污染指标的去除效果极佳;并对部分时段超标区域的超标原因进行了分析,提出了部分解决方案,此结果将为大亚湾核电基地污水处理系统的改进提供一定的参考。

The water quality in entrance and exit of eight wastewater treatment plant were monitoring for two years, in order to better evaluate the operation effect of the biological contact oxidation and activated sludge technology in sewage treatment plant, at Dayawan Nuclear Base, The results showed that the removal rates of BOD, CODer, SS, TP and NH3-N from the sewage treatment plant were 9%9 %, 99.5 %, 93.2 %, 9%6 %, 97.2 %, respectively, indicating the excellent wastewater treatment performance of biological technology and long-term underrating of the wastewater treatment plant. The results had a directive and practical importance for the design and late running of the sewage treatment plant.
