3400吨/天啤酒废水处理装置工程设计 作者：龙艳 指导老师：肖菡曦 （湖南科技大学化学化工学院 湘潭，411201） 摘　要:根据对原水水质的分析，在大量查阅了啤酒废水处理相关文献的基础上，综合考虑技术经济因素，确定了UASB—SBR艺，3400 t/d，废水CODCr 4150mg/L，BOD 2600 mg/L， SS 1893 mg/L，N 80 mg/L，pH值6～9。经UASB反应器处理后COD去除率为85%，BOD去除率为90%，其出水进入SBR反应器中，经SBR反应器处理后COD去除率为85%，BOD去除率为92%，SS去除率为75%，N的去除率为85%，其出水直接排入河流，最终出水COD约为4 mg/L，BOD约为19mg/L，SS约为27 mg/L，N约为12 mg/L，。各处理单元所排出的污泥经重力浓缩及脱水后直接外运。产生数量可观的沼气，沼气可回收对UASB反应器进行加热。总投资额约为万元，废水处理成本约为元/m3。 Design of the 3400 t/d brewery production wastewater treatment system Designer: Long Yan Tutor: Xiao Hanxi (School of chemistry and chemical engineering, Hunan University of Science and Technology Xiangtan,411201) Abstract: Based on analysis of the raw wastewater, we employed the UASB-SBR process. The design capacity is 3400 t/d and CODCr is 4150mg/L, BOD is 2600 mg/L, SS is 1893 mg/L, NH3-N is 80 mg/ L, pH value is 6~9. The elimination rate of CODCr in UASB reactor is 85%, BOD is 90%, The elimination rate of CODCr in SBR reactor is 85%, BOD is 92%, SS is 75%, NH3-N is 85%, the CODCr of the discharged water would be 7 4 mg/L, BOD would be 19mg/L, SS would be 27 mg/L, NH3-N would be 12 mg/L，requirement of the national lntegrated Waste Water Discharge Standar.
