1北京理工大学珠海学院 16 届本科生毕业设计深圳市某市政污水处理厂工程设计摘 要在如今社会，水资源的需求量越来越大。水污染已经被联合国列为一项非常严重的自然灾害，与空气污染和化学污染并列。水污染的危害极大，它会危害人体的健康、渔业和农业生产，也会增加清洁水供应的支出。水污染还会对生态系统构成危害:水体的富营氧化以及动植物物种的损失。此设计主要根据城市规划，地形条件，气候条件，河流的水文条件，依据排水管道系统的布置原则确定排水管网的平面设计，在保证排水安全通畅的前提下，使工程的造价最低。再根据生活污水的水量、水质条件及工业污水的水量以及受纳水体可接受的污染物的量确定污水的处理程度，进而确定污水处理工艺，并进行技术经济比较。为达到污水厂要求的排放标准，本工程设计选择氧化沟工艺结合深度处理和氧化沟工艺结合 MBR技术两种方案。通过对这两种具有脱氮除磷功能的污水处理工艺设计并进行经济技术比选，确定氧化沟工艺为较优方案。而污泥处理则采用浓缩、脱水工艺。 关键字：城市污水处理厂；氧化沟工艺；脱氮除磷；污泥处理; MBR 2北京理工大学珠海学院 16 届本科生毕业设计AbstractIn today's society, the demand for water resources is increasing. Water pollution has been listed by the United Nations as a very serious natural disaster, alongside air pollution and chemical pollution. Water pollution is so harmful that it endangers human health, fisheries and agricultural production, and increases spending on clean water supplies. Water pollution can also be harmful to ecosystems: the rich oxidation of water bodies and the loss of plant and animal species. Therefore, it is urgent to control the water pollution. This design is mainly based on the urban planning condition, climate condition, river hydrology condition, according to the layout principle of drainage pipe system, determine the layout design of drainage pipe net, make the cost of the system lowest under the premise of ensuring the drainage safe and smooth. Then according to the quantity of domestic sew...
