中文题目：阜新市城市污水生物接触氧化法+深度处理工艺设计外 文 题 目 ： Fuxin City Sewage Biological Contact Oxidation + Advanced Treatment Process Design毕业设计（论文）共 69 页（其中外文文献共 15 页） 图纸共 5 张完成日期：2025 年 6 月 5 日 答辩日期：2025 年 6 月 18 日摘要当今，随着人民生活水平的提高，环境污染日益严重，加强城市生活污水的治理迫在眉睫。现拟建一座阜新市生活污水处理厂，处理规模为 60000m3/d。为达到规定的污水排放标准，对比多种工艺后，本设计选用了生物接触氧化法与深度处理相结合的工艺来处理城市污水。该法是现今生活污水处理厂常用的一种工艺。该法流程简单，操作简便，脱氮除磷效果好，省去了污泥回流过程，产泥量少，不易发生污泥膨胀，动力消耗也不高，而且该法对池子的利用率高，节约了基建投资和运行费用。关键词：城市污水；生物接触氧化；深度处理；污泥处理ABSTRACT Today, with the improvement of people's living standards,environmental pollution increased,wastewater governance should be strengthened in imminent municipal. Now proposing a sewage treatment plant in Fuxin city, deal with the scale of 60000m3/d.To achieve the required effluent standards,compared to a variety of techniques,Based on the present design ， using biological contact oxidation process combined with the depth of processes to deal with municipal sewage.The method is a modern sewage treatment plant processes commonly be used. The method is simple, easy operation,removaling nitrogen and phosphorus well,eliminating sludge return process,producing less sludge,less prone to sludge bulking,and power consumption is not high,and the utilization of the method of the pond is high, saving construction investment and operating costs.Key words: municipal wastewater; biological contact oxidation; depth of treatment; sludge treatment目录前言·····························································...
