水处理的方式包括物理处理和化学处理。人类进行水处理的方式已经有相当多年历史，物理方法包括利用各种孔径大小不同的滤材，利用吸附或阻隔方式，将水中的杂质排除在外，吸附方式中较重要者为以活性炭进行吸附，阻隔方法则是将水通过滤材，让体积较大的杂质无法通过，进而获得较为干净的水。另外，物理方法也包括沉淀法，就是让比重较小的杂质浮于水面捞出，或是比重较大的杂质沉淀于下，进而取得。化学方法则是利用各种化学药品将水中杂质转化为对人体伤害较小的物质，或是将杂质集中，历史最久的化学处理方法应该可以算是用明矾加入水中，水中杂质集合后，体积变大，便可用过滤法，将杂质去除。

市政污水处理工程案例(缺氧+传统活性污泥法)

　　某污水处理厂是大连市修建的一座大型污水处理厂。该厂的建设引进关键技术、监控装置和设备，提高污水处理效率，充分利用生物能，节约能耗，节省用地，降低工程造价和运行成本。

　　该污水处理厂的工艺设计，在进行各种工艺方案比较的基础上，仍选用鼓风曝气的设计方案。其理由是大型污水处理厂采用鼓风曝气工艺管理简便、运行可靠。该污水处理厂肖化吸收了国外的先进技术，对每个单项构筑物及污水、污泥处理的细部方案都作了改进，如进水泵房及污水量计量的自动控制、洗砂排砂、排泥浓度控制、溶解氧白控、脱氨反硝化工艺、二沉池出水槽新工艺、消化池投泥方式、大型消化池的沼气搅拌、沼气发电升压联网、沼气锅炉及排泥阀、可调堰、细格栅等先进技术都在该厂得到了应用。

　该厂污水处理系统分4个系列，4个圆形初沉池排成一行，4个曝气池组成田字形，8座二沉池设在厂区南侧，临近北塘排水河，使处理出水可就近排人河道。污泥处理区设在厂的西北角，5个消化池组成梅花形，污泥处理的控制室设在5个捎化池的中央。北侧设有两个沼气储罐、污泥脱水机房和沼气发电机房等。

　主要处理构筑物及设备参数：

   1.进水格栅

   格栅是污水处理厂的道预处理设施。该厂设6台垂直格栅，由计算机程序控制。高水位时格栅清污机将连续工作，运送格栅拦截的浮渣的皮带运输机与格栅清污机联锁运行，在所有格栅停止工作后，皮带运输机仍将继续运行一段时间。

   6台垂直格栅每台宽2m，栅条净距25 mm。

   2.进水泵房

   设6台HLWB-10型立式涡壳混流泵，5用1备。

   水泵参数：流量1.32立方/秒，扬程13.2m，电机动率260kw。

   泵房设有6个控制水位，控制5台泵的运行。为避免个别水泵负荷偏重而反复起动，水泵将依次循环投人运行。当某台泵因故障停止工作时，另一台泵将自动投入运行。

   3.曲面格栅

   8台曲面格栅设在沉砂池的端部。每台格栅宽度1.2m，栅条曲率半径2.0 m，栅条净距10m。

   每台格栅的清污动作根据水位模拟信号由计算机控制。当水位差处于正常值时，清污工作将按设定时间动作；当前后水位差超过设定值时，清污工作将连续进行。如果清污工作连续操作时间过长，计算机将发出报警信号。

   曲面格栅刮出的浮渣落在皮带运输机上，皮带运输机的运行与格栅清污机联锁，清污工作停止后，运输机仍将运行一段时间。  

   4.沉砂池

   曝气沉砂池设有6条廊道，每条长30m、宽4m、深4.3m，水力停留时间约6min。

   池内设有振动空气(VIBRAIR)曝气器648个，供气量为5184立方米/小时。全池设两座吸砂工作桥，每个工作桥上有3个空气提砂装置，负责3条廊道的吸砂。污秽的砂水被提升到洗砂槽，经搅拌后，有机物随洗砂水流回进水泵房，砂水被送至分砂机进行进一步脱水。分砂机设在进水泵房的上部建筑顶层，以便脱水的砂粒流入砂斗运走。

   吸砂工作桥用行程开关控制，其上设有刮渣设施，以清除池内浮渣。空气提砂装置要求注续工作，由计算机控制。当空气压缩机发生故障时，备用机可自动投入。空气压缩机、分砂机和泵的运行状态由计算机监控，如出现故障将自动报警。

   5.初沉池

   初沉池曾设计了矩形和圆形两种方案，从运行管理、占地和混凝土用量等方面进行比较，认为圆形辐流式沉淀池设备运转可靠、管理简便，故采用了4座配有周边驱动全桥式刮混机的辐流式沉淀池，直径达60m，水深4.5 m，沉淀时间2.26h。

   初沉池运行的关键是排泥，4座池轮流排泥的程序由计算机控制。每个排泥阀靠频率/时间自动操作。其功率/时间将根据计算机监测到的污泥浓度和流量束进行调整。排泥阀分两部分，启用的是电动阀门，排泥口用的是可手动调节的升降阀，该阀属非标设备。

   6.初沉污泥泵房

   为防止排泥系统出现堵塞故障，在两座初沉池间设一座污泥泵房。安装GF单螺杆泵4台，两座泵房共装8台污泥泵。污泥泵按频率邝j问自动操作，并由计算机进行调整，两座污泥泵房交替运行，在泵房的出口处设有污泥浓度模拟测量装置，污泥进人浓缩池前进行

流量检测。这些信号进入计算机后，将用于计算污泥的排放量，以调整排泥技术上频率和排混的持续时间。
