摘要
探讨了生物接触氧化法的连续进水、间歇曝气运行方式与传统的连续进水、连续曝气运行方式在不同负荷下COD、NH3-N、TN和TP等的去除情况。结果表明:在停留时间5.8h,连续曝气4h,停止曝气1.8h的情况下,间歇曝气运行方式的混合样出水水质达到了传统运行方式的处理效果,满足《城镇污水处理厂污染物排放标准》(GB18918—2002)中一级B标准的要求。为节能工艺的开发提供了指导。
ting modes of organic loading The removal effects of COD, NH3-N, TN and TP by bio-contact oxidation process under operacontinuous influent intermittent aeration and continuous influent continuous aeration at different levels were discussed. The results showed that： when the HRT was 5.8 h, the continuous aeration time was 4 h and the aeration pause time was 1.8 h, the water treatment effect under the intermittent aeration mode was equal to that under the continuous aeration mode, and the effluent quality met the specification for level B of grade 1 in Discharge standard of poUutants for municipal wastewater treatment plant（GB 18918- 2002）. The study could provide guidance for the development of enenry-saving process.
