PAGE 成都电子机械高等专科学校毕业设计（论文） PAGE I 接触氧化法处理小区废水 环境工程专业 摘要 本设计以“某生活小区污水为原水进行处理后回用”这个主题为研究对象，利用所学的知识，结合工程实际，对小区污水处理站的工艺流程、主要构筑物和整体布局进行了设计。污水处理与回用系统以生物接触氧化法为二级处理方法，以过滤和消毒为深度处理工艺，对污水进行处理，出水回用于小区生活杂用水；同时对各部分产生的污泥进行了处理，达到了无害化。整个系统流程简洁，处理效率高，出水水质稳定，操作管理方便，占地少；平面布局紧凑有序，地面进行绿化，清洁美观，给居民营造了一个健康的生态小区环境。 关键词：生物接触氧化工艺 生物膜 填料 回用 生态小区 Abstract This paper is about a sewage treatment and reuse system.The crude wastewater is from a biotope and the treated water is to be used to flush the toilets、vehicles and for afforestation .The system use biological contact oxidation process as the main and filtration and decontamination as the advanced treatment process，at the same time，the sludge formed in the process is concentrated and dewatered so as to reduce its size and make it innocuous .The whole system is efficient and automatic，it’s very easy to operate and manage，and the effect is good and stable.The area of the sewage disposal plant is small，the style of the main structures is harmony with the residences，and the ground surface is afforested . All these make the sewage disposal plant clean and artistic，a healthy ecological biotope is supplied to people .
