摘要
对常规活性污泥法和一体化氧化沟工艺在中原油田基地污水厂的应用效果进行了对比分析。月度抽查对比监测发现,两种生物处理法对有机物均有较好的去除效果。一体化氧化沟工艺是一种新型的生活污水处理技术,它对SS、NH3-N的去除效果优于常规法。连续三天的日均值监测结果表明,新工艺对各种污染物的去除效果达到91%以上。这种工艺集通氧、沉淀、废渣分离和回收为一体,占地面积小,操作简单,在中原油田污水站取得了较好的应用效果。
The integrative oxidation ditch process is a new technology for domestic sewage disposal. The process integrates the functions of oxygen aeration, settle, sludge separation and sludge recovery. It retrenches area of land occupation. The unit is characterized by compact configuration and simple operation. The application of the integrative oxidation ditch process in Zhongyuan Oilfield Sewage Treatment Plant shows that the removal rates of COD, BOD5, NH3-N and SS are all over 90% after application of the new process and detection for 9 months.
