摘要
围绕城市污水处理问题,设计开发了微孔曝气变速氧化沟处理系统。先简要分析了该技术的研究背景,然后梳理选择池、氧化沟、二沉池、附属装置的配置思路和安装调试过程,并在此基础上评估了系统的运行效果。结果发现:系统整体的污染处理效果较好,COD、氨氮的平均去除率可达93%和95%,TN、TP的平均去除率可达83%和94%,试验用污泥硝化能力可在90 d后恢复,所以具有一定的可借鉴意义。
Focusing on the issue of urban sewage treatment,a micro-porous aeration variable-speed oxidation ditch treatment system was designed and developed.Firstly,the research background of this technology was briefly analyzed.Then,the configuration ideas and installation and commissioning processes of the selection tank,oxidation ditch,secondary sedimentation tank and auxiliary devices were sorted out.On this basis,the operation effect of the system was evaluated.The results show that the overall pollution treatment effect of the system is relatively good.The average removal rates of COD and ammonia nitrogen can reach 93%and 95%respectively,and the average removal rates of TN and TP can reach 83%and 94%respectively.The nitrification capacity of the experimental sludge can be restored after 90 days,so it has certain reference significance.
