1.2 设计进水水质表1.1 污水厂设计进水水质（mg/L）冬季最低水温，18℃。
1.3 设计出水水质2 久保田国祯MBR工艺2.1 MBR工艺特点与传统的生物处理工艺相比，MBR 工艺具有以下主要特点，（1）出水水质优质稳定出水水质较好，可降低对环境的负荷，还可完全隔离病原性大肠杆菌，所以膜处理出水完全可以直接回用于冲厕、农业灌溉等方面。
为了实现深度处理，膜处理出水也可直接提供给RO膜装置。
（2）占地面积小MBR工艺与传统工艺相比可在更高的MLSS(污泥浓度)下运行，所以与传统工艺相比，较小的池容可处理相同的水量。
不仅是生物反应池变小，另外MBR 工艺无需设置初沉池和二沉池，因此占地面积较小。
MBR工艺改造原有的传统工艺，不用新增构筑物就可以提高处理量，同时能达到深度处理水平。
（3）剩余污泥产量少MBR工艺可以在高容积负荷、低污泥负荷下运行，剩余污泥产量低（理论上可以实现零污泥排放），降低了污泥处理费用。

久保田平板膜技术手册
久保田平板膜技术手册3.1 MBR膜MBR是膜生物反应器（Membrane BiologicalReactor）的英文缩写，是高效膜分离技术与活性污泥法相结合的新型污水处理技术，可用于有机物含量较高的市政或工业废水处理。
MBR膜生物反应器是整个垃圾渗滤液处理的最核心单元，其性能的好坏，直接影响着系统的处理出水。
通过大量的渗滤液处理实践，我方设计采用了性能和质量较为稳定的久保田平板液中膜生物物反应器处理单元。
3.1.1 久保田平板液中膜结构单片液中膜由滤板，膜垫，薄膜层，取水口组成。
滤板由外框架和内支撑组成。
滤板主要是对附着在表面的膜垫和薄膜层起支撑作用。
用于市政污水处理的滤板主要有两种尺寸。
一种是1000mm×500m，另一种是1600mm×500m。
滤板中的内支撑上有水流沟槽，可以使得过滤后的水能够自由地在其中流动。
膜垫是薄膜过滤层的物理支撑。
在滤板的两面均紧密地附着有膜垫。
薄膜层的材料为聚氯乙烯，薄膜层均匀地附着在膜垫的表面。
取水口是最终处理后水的出口。
过滤后的水经过滤板内支撑上的水流沟槽，在水力压力或外部抽吸力的作用下流出。
3.1.2 久保田平板液中膜的主要技术指标液中膜平均孔径：0.4um （属于微滤膜，MF）单片膜的有效过滤面积：EK型尺寸：1000mm×490mm 有效过滤面积：0.80 m2EW型尺寸：1600mm×500mm 有效过滤面积：1.25 m2膜通量：0.4 ~ 0.8 m3/d/m2曝气风量：7 L/min/片运行方式：8:2或9:1循环污泥量：进水2-3倍MLSS：15000－20000 mg/L清洗压降：>2 mH2O3.1.3 久保田平板液中膜组件的构成如右图所示，液中膜组件由膜框架，膜支架（液中膜）曝气框架，曝气管，软管，集水管组成。
膜支架即为液中膜。
每个液中膜组件中可以安装最多200片膜支架。
膜框架是用来支撑膜支架的，一般用不锈钢材料制成。

B. 按BOD5容积负荷计算
取BOD5容积负荷NV为1.0 Kg/(m3.d) WBOD5 = Qd×S0×10-3 = 1000×200×10-3 = 200 Kg.BOD5/d V= WBOD5÷NV = 200÷1.0 = 200 m3
由于根据BOD5容积负荷算出的池有效容积小于膜 平面布置所得的池容积，故MBR池容积及尺寸按 膜组件安装尺寸确定。
