摘　　要：一体化氧化沟占地面积小、工艺流程简单,因此已成为环保领域的研究热点.文中采用侧沟式一体化氧化沟技术处理生活污水,进行生物脱氮研究.试验期间,一体化氧化沟进水CODCr为200.00-400.00 mg/L,NH4^＋-N进水从1.24 mg/L迅速提高到39.72mg/L;出水CODCr保持在15.00mg/L以下,氨氮去除效果保持稳定,出水氨氮质量浓度在多数情况下保持在2.00mg/L以下.文中还分析了碱度、CODCr/NH4＋-N质量比对生物硝化作用的影响,并就如何提高反硝化效率提出了建议.At present, the Integrated Oxidation Ditch has become a research hotspot in the environmental protection field due to its small space occupancy and simple process. In this paper, a side-channel-separator Integrated Oxidation Ditch was used to treat the municipal sewage and to perform the biological nitrogen removal. In the experiment, the influent CODCr ranged from 200. 00 to 400. 00 mg/L, the content of NH4^＋ -N was rapidly increased from 1.24 to 39.72 mg/L, the effluent CODc~ was kept at less than 15.00mg/L, and the effluent content of NH4^＋ -N was generally kept at less than 2. 00 mg/L, showing a stable NH4^＋ -N removal efficiency. Furthermore, the effects of alkalinity and CODCr/NH4^＋ -N mass ratio on the biological nitrification process were analyzed, and some suggestions were proposed for promoting the denitrification efficiency.
