1 给水排水工程专业毕业设计说明计算书设计题目: 郑州龙口五污水处理厂设计学校: xx 工程大学班级:给水排水专业姓名: xx 学号: xxxxxx 指导教师: xx 完成日期: xx年x月x日 2 摘要东营市河口区设计人口 23万, 居住建筑内设有室内给排水卫生设备和淋浴设备。工业污水量为 万米 3/ 平均日,其中包括工业企业内部生活淋浴污水。城市公共建筑污水量按城市生活污水量的 30% 计。排水分体制: 完全分流制。根据测量的水量、水质和环境容量降低的结论确定污水及污泥处理应达到的标准,本节对其处理工艺流程进行方案筛选,并通过论证选择合理的污水及污泥处理工艺流程。本设计采用 A+A 2 /O 工艺。城市污水经处理后, 50% 就近排入水体—金水河。 50% 作为市政杂用水, 出水水质应执行《城市杂用水水质标准》( GB/T18920-2002 )。关键词: A+A 2 /O 工艺完全分流制水质标准污水和污泥处理工艺 abstract Design of Dongying City estuary population of 23 million, residential buildings are equipped with indoor plumbing sanitary equipment and shower of industrial sewage of m/ average day, including the internal life of industrial waste water amount of urban public buildings by municipal sewage effluent for 30% of total sub-system: full triage system. According to measurements of water, reduced water quality and environmental capacity of sewage and sludge treatment conclusions to determine the criteria to be met, this section of its screening process flow for programs, and by demonstrating a reasonable choice of sewage and sludge treatment design uses A+ A 2 /O process. After treatment of urban sewage, 50% into the nearest body of water - % of the plex water, water quality should be the implementation of "urban miscellaneous water quality standard" (GB/T18920-2002). Key words: A+ A 2 /O process water quality standards fully streaming process sewage and sludge treatment 3 目录第一章概论......................................................................................................................... 6 设计依据....................................................................................................................... 7 设计水量及水质........................................................................................................... 7 设计人口与当量人口.................................................................................................... 7 处理程度............
