摘　　要：以贵州某高原环境下城镇污水一体化氧化沟工艺优化提标工艺段COD、氨氮、硝氮、总氮、总磷的含量变化作为检测分析指标,结果表明:改进优化后的氧化沟工艺,COD去除率为79.3%,COD去除率较改造前增加了3.4%;氨氮总体去除率为60.1%,较改造前去除率增加了4.0%;硝氮去除率为56.4%,较改造前增加了10.5%;总氮去除率为59.2%,较改造前增加了5.4%;总磷改造后去除率为81%,较改造前增加了13.8%。工艺技改优化后的脱氮除磷效果有较显著提高。In this paper,the concentrations of COD,ammonia nitrogen,nitrate nitrogen,total nitrogen and total phosphorus were used as detection indexes to analyze the optimization effect of an integrated oxidation ditch for sewage treatment in Guizhou.The results showed that,after the optimization,the removal rates of COD,ammonia nitrogen,nitrate nitrogen,total nitrogen and total phosphorus were 79.3%,60.1%,56.4%,59.2% and 81%,respectively,3.4%,4.0%,10.5%,5.4% and 13.8% higher than before,respectively.The optimized integrated oxidation ditch achieved obviously higher removal efficiency of nitrogen and phosphorus.
