摘 要
本设计为某医院污水处理设计。设计程度为初步设计。医院污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。而且此污水中还含有少量的NH4-N及S-2，亦属于去除目标。
该啤酒废水处理厂的处理水量近期为4000m3/d,远期为7000m3/d。原污水中各项指标为：BOD浓度为960mg/L,COD浓度为1700mg/L，SS浓度为500mg/L，NH4-N浓度为80mg/L,S-2浓度为20mg/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≤30mg/L，COD≤100mg/L，SS≤70mg/L，NH4-N≤15mg/L,S-2≤1.0mg/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CASS池，可有效去除污水中的BOD、COD、NH4-N及S-2。本设计工艺流程为：
啤酒废水 → 污水提升泵房→细隔栅 → 调节池 → UASB反应器
→CASS池 → 巴氏计量槽 → 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。
设计内容包括：设计任务书、设计说明书、设计计算书、平面布置图、高程布置图、污水提升泵房图（施工图深度）、UASB反应器平剖面图、浓缩池平剖面图、CASS池平剖面图。

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. And in this waste water also contains few NH4-Nand S-2, it belongs to the goal of removals too.
The water which needs to be treatment in the beer waste water treatment plant is 4000m3/din near future and 7000m3/din a long-term. Various target in the raw waste water is: the concentration of BOD is 960mg/L, the concentration of COD is 1700mg/L, the concentration of SS is 500mg/L, the concentration of NH4-N is 30mg/ L , the concentration of S-2is 20mg/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≤30mg/ L, COD≤100mg/ L, SS≤70mg/ L,NH4-N≤15mg/ L, S-2≤1.0mg/ 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 CASS of anaerobic oxygen biology methods, which could remove BOD, COD,NH4-Nand S-2in the waste water. The technological process of this design is:
Beer waste water → Screens → The sewage lift pump house →Screens → Requality tank → Reaction tank of UASB → Precipitating tank of erects style → Tank of CASS → Gauge measurement → 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.
The content of the design includes: design project description, design instruction booklet, calculation booklet, the floor-plan, the elevation general arrangement, the sewage lift pump
house (construction drawing depth), the horizontal section chart of reaction tank of UASB, the horizontal section chart of concentration tank of erects style, the horizontal section chart of CASS tank.
