Eight, 1000 punishment. (5) significant near miss should be attempted as the case of responsible for the accident and constructio-of leadership, along with 500 3 设备的处理能力大; ?生物膜法的剩余污泥量少。在生物膜的厌氧层中栖息着厌氧菌能降解好氧过程合成的剩余污泥，从而使总的剩余污泥量大大地减少; ?膜法运运行管理比较方便，它不需要污泥回流，因而不需要严格控制回流污泥量和剩余污泥量，又不存在活性污泥法中常见的污泥膨胀和污泥流失，运行比较稳定，还可间接运行，遭破坏恢复起来比较快，对有机负荷和水力负荷的变化波动影响较小，出水水质比较稳定; ?由于充氧是在填料下直接曝气，气泡通过填料再次破裂提高了充氧效率，故其动力消耗要比活性污泥法小。 污水通过生物接触氧化池有80-90%的CODcr在这里被去除，使出水达到排放标准。 此外，医院污水含有病原体，如蛔虫卵、肝炎病毒、结核菌、痢疾和其他流行病菌等，如果不经过消毒处理,任其排入城市地下道或环境水体,就会严重污染水源,传播疾病,危害人民群众的健康。尤其当医院的污水连同其污泥不经无害化处理而直接用于蔬菜瓜果的施肥,将会导致细菌性、病毒性疾病和寄生虫病的发病率骤增。因此，为防止疾病的传播，必须对出水进行消毒处理。 目前，常用的消毒工艺有:液氯消毒、臭氧消毒、ClO2消毒、次氯酸钠消毒以及紫外线消毒。紫外线消毒对出水的悬浮物要求较高，不适合本工程。臭氧消毒相对工程投资较高，且对土建、电气要求严格。次氯酸钠消毒使用方便，虽然投资费用低，操作简单，但是产生致癌物,产生二次污染。综合国内外的实际情况，本工程采用ClO2消毒。 4.2 污水工艺流程框图 上清液 污泥贮池 定期外排 泵 污泥 医院 格栅 调节池 缺氧池 接触氧化池沉淀池消毒池脱氯池达标排放 污水 齿、池 齿、齿、齿、齿、齿、齿、污水回流 池 池 池 ClO发生器 脱氯机 2 污水 污泥 98 compressor, fan and pump installation engineering construction and acceptance specification for lifting-2009 mechanical equipment installation engineering construction and acceptance specification for 5 GB50275-ure vessel 4 GB502311997 steel welded atmospheric press-T47352005 vertical cylindrical steel pressure vessel steel welded specification for construction and acceptance of oil tank 3 JB/ -98 2 GB50128-st of welded plate II, mechanical equipment installation engineering 1 GB1502000 steel pressure vessel products mechanical properties te-2005 pressure vessel welding procedures of steel pressure vessel NDT 9 JB/T4744-2000 8 JB4730-2000 of welding procedure qualification for steel pressure vessels 7 JB/4709-petrochemical JB/ T4708 2004-92 technical specification for welding of aluminium and its alloys 5 low temperature steel welding procedure 6 SH3525-2002 industrial pipe welding engineering code for construction and acceptance of field equipment 4 HGJ222-results for grade 3 GB5023689 steel welds manual methods of ultrasonic inspection and testing -Ray lighting and quality rating of 2 GB11345-2005 steel fusion welded butt joints, welding engineering-ld perform in the construction standards and specifications, serial number a 1 GB3323n team injuries accident penalty provisions, mutatis mutandis.
