重庆啤酒集团某分厂4000吨污水处理工程设计(含CAD图)(外文翻译,计算说明书10000字,CAD图8张)
摘 要
本设计为某啤酒废水处理设计。设计程度为初步设计。啤酒废水水质的主要特点是含有大量的有机物,属高浓度有机废水,故其生化需氧量也较大。该啤酒废水处理厂的处理水量为4000 ,不考虑远期发展。原污水中各项指标为:BOD浓度为800mg/L,COD浓度为1500mg/L,SS浓度为600mg/L。因该废水BOD值较大,不经处理会对环境造成巨大污染,故要求处理后的排放水要严格达到国家二级排放标准,即:BOD≤20mg/ L,COD≤100mg/ L,SS≤70mg/ L。
经分析知该处理水质属易生物降解又无明显毒性的废水,可采用两级生物处理以使出水达标。一级处理主要采用物理法,用来去除污水中的悬浮物质和无机物。二级处理主要采用生物法,包括厌氧生物处理法中的UASB法和好氧生物处理法中的SBR法,可有效去除污水中的BOD、COD。本设计工艺流程为:
啤酒废水 → 格栅 → 污水提升泵房 → 调节沉淀池 → UASB反应器
→ SBR池 →处理水
整个工艺具有总投资少,处理效果好,工艺简单,占地面积省,运行稳定,能耗少的优点。

Abstract
This design is one beer waste water treatment. The degree of the design is in a preliminary phase. The main distinguishing feature of the beer waste water is that it contains the massive organic matters, so it belongs to the high concentration organic waste water, therefore its biochemical oxygen demand is also high.
The water which needs to treatment in the beer waste water treatment plant is 3000 , regardless of the specified future development. Various target in the raw waste water is: the concentration of BOD is 800mg/L, the concentration of COD is 1500mg/L, the concentration of SS is 600mg/L. For the beer waste water's BOD is high, it could pollute the enviroment if drained before treatment, so it request the beer waste water which drained must be strictly treated to the two effluence standard in the country, which is as following:BOD≤20mg/ L,COD≤100mg/ L,SS≤70mg/L.
After the analysis, the quality of this processing water belongs to the waste water that easy biology degrade and not have the obvious poison, could use two levels of biological treatments to cause the water drained meet the designated standard. First level of processing mainly uses the physical methods, which removes the suspended matter and the inorganic substance in the sewage.Second levels of processing mainly uses the biology methods, consists of UASB of demand oxygen biology methods and SBR of anaerobic oxygen biology methods, which could remove BOD, CODin the waste water. The technological process of this design is:
Beer waste water → Screens → The sewage lift pump house → Regulates precipitating tank → Reaction tank of UASB → Tank of SBR →Treatment water
The entire technological process have the characteristics of lower investment, good treatment effect, easy technology process,using small area, running steady, and consuming lower energy.
