T城自来水厂工程设计
设计内容简介：本设计根据山东省某城市的设计资料，进行自来水厂设计，选择合适的工艺流程，计算后得出平面布置和高程布置结果。具体步骤为分析研究水质资料，确定给水处理厂工艺流程，进行处理构筑物型式的选择，进行各单项处理构筑物的设计计算，确定水厂的附属构筑物和建筑物，进行水厂的平面布置，进行水头损失计算，确定水厂的高程布置。净水厂设计流量4.5万m/d，水源为地表水源，根据地表水水质要求以及经济技术限制，选择方案工艺流程如下：
原水→泵站→管式静态混合器→水平轴机械絮凝器→平流沉淀池→普通快滤池→臭氧接触池→生物活性炭滤池→清水池→二级泵站→用户 关键词：工艺流程 、构筑物计算、方案布置
