6、.1设计题目描述(1)设计题目某城市污水处理厂工艺初步设计。(2)设计内容根据任务书所给定的资料，综合运用所学的基础、专业基础和专业知识，设计一个中小型污水处理厂。①确定污水处理方法和工艺流程；②选择各种处理构筑物形式，并进行工艺设计计算（计算书中要附计算草图）；③估算各辅助构筑物的平面尺寸；④进行污水厂平面布置和高程布置。(3)原始资料该城市位于湖北地区原始资料如下：①设计规模：近期：20万人；远期：40万人；最大生活污水量为180-200。.工业污水占最大生活污水量的1/3。按近期计算，预留远期面积，用虚线画出。②城市污水水质：SS=210mg

7、/L，去除率为60%；BOD＝200mg/L，要求出水为25mg/L。22③当地最高水温为30℃，。④夏季主导风向为东南风。⑤污水厂北面200米处有一条河流，最高洪水位为46.00米，常水位为42.00米。⑥污水厂地形平坦，设计标高为48.00米；地下水位标高为42.00米，地基良好。⑦城市污水总管从污水厂南面进入，干管终点水面标高为43.00米，管径1200mm。2.2设计要求设计时间为一周。设计成果要求如下：(1)设计说明书（含课程设计的目的、原始资料、工艺方案比较、污水处理构筑物选型及主要设计参数、污水厂的平面布置、高程布置及设计的心得体会等

8、，A4纸打印）(2)设计计算书（污水处理构筑物的设计计算、高程计算、草图）(3)污水处理厂总平面图一张（1号图，1∶500
