二、设计依据
2.1污水水量
工程设计处理水量：100m3/d
2.2污水水质
污水水质为：
CODCr≤600mg/l SS ≤200mg/l NH3—N≤70mg/l PH ：6～9
2.3处理后可排放水水质
污水经处理后，出水水质应满足如下控制指标：
CODCr≤150mg/l SS≤150mg/l PH：6—9
2.4其它设计基础资料
□ 给排水设计手册
□ 厂方提供的有关技术参数及要求
□ 土建成本估算中的地基处理，因没有地质资料，暂按

亚粘土地基考虑，地耐力要求?120kn/m2。土建造价按常规，降水费未计。 □ 电费：0.7元/度
三、设计原则
3.1 确保处理能力与出水水质 3.2 节约能耗，降低运行成本 3.3 易于操作，易于运行 3.4 尽量减少占地面积
四、设计范围
4.1水处理部分
自废水进入污水处理厂格栅井开始，经各处理单元后，至标准化排放口为止。
4.2其它部分
包括建筑结构、电气自控、照明等。
