1、摘要本次设计为H处理5000吨的啤酒废水的污水厂设计。是在前期的城镇污水厂设计基础上的工业污水处理设计。啤酒废水有:COD,BOD等值较高,但是水量较小的特点。本次设计原进水指标为COD:1500mg/L;B0D5:800mg/L;SS:400mg/L;NII3-N:45mg/L;TP:6mg/L;pH:6~7。处理后将达到COD:W60mg/L;B0D5:^20mg/L;SS:^20mg/L;NH3-N:<15mg/L;TP:Wlmg/L;pH:5~11。设计厂区布置要求:根据厂方提供的资料,废水处理
2、站拟建在生产区以北,现有空地,场地基本平整,土质良好。废水通过厂区暗渠排入废水处理站,渠底标高为453.50m;经处理后的水直接排放,受纳水体洪水位标高为397m。拟建地夏季主导风向西南风,年平均气温13.4摄氏度,极端最高气温40.9摄氏度,极端最低气温-11・7摄氏度,最大冻土深度为0.5mo总设计流程考虑用厌氧加好氧的方案,厌氧工艺选定为UASBoUASB设备简单,运行方便,勿需设沉淀池和污泥回流装萱,不需要充填填料,也不需在反应区内设机械搅拌装置,造价相对较低,便于管理,且不存在堵塞问题。UAS
