高速公路服务区污水一体化设备的组成部分

　　高速公路服务区污水一体化设备由初沉池、接触氧化池、二沉池、消毒池及消毒装置、污泥池、风机房、风机组成，下面是详细的介绍。

　　(1)初沉池：设备初沉池为竖流式沉淀池，污水在沉淀池的上升流速为0.6-0.7毫米/秒，沉淀下来的污泥用空气提至污泥池。(注：WSZ-A O.5-5m3/h不设初沉池)

　　(2)接触氧化池：初沉后水自流至接触池进行生化处理，接触池分为三级，总停留时间为 1小时以上。加强型设备接触氧化时间可达6小时，填料为新颖梯形填料。易结膜、不堵塞。填料比表面积为160m2/m3，接触池气水比在12:1左右。(注WSZ-A 0.5-5T/h，接触池为二级)

　　(3)二沉池：生化后污水流到二沉池，二沉池为二只竖流式沉淀池，它们并联运行。上升流速为O.3-0.4毫米/秒。排泥采用空气提升至污泥池。(注WSZ—A0.5-5mT/h，污泥自流到污泥池中)

　　(4) 消毒池及消毒装置：消毒池按规范：“TJI4—74”标准为30分钟，若是医院污水，消毒池可增加停留时间至1-1.5小时，采用固体氯片接触溶解的消毒 方式，消毒装置能根据出水量的大小不断改变加药量，达到多出水多加药，少出水少加药的目的。其它消毒装置可另行配制。(注：如用于工业污水消毒池与消毒装 置可以不要)

　　(5)污泥池：初沉池、二沉池的所有污泥均用空气提至 WSZ-A的污泥池内进行好氧消化。污泥池的清液回流至接触氧化池内进行再处理。消化后剩余污泥很少，一般1-2年清理一次。清理方法可采用吸粪车从污泥 池的检查孔伸入污泥底部，进行抽吸外运即可。(WSZ-A 0.5-5T/h，污泥采用厌氧消化)

　　(6)风机房、风机：设备 WSZ-A的风机房设在消毒池的上方，进口采用双层隔音，进风口有消声器、风机过滤器，因此运行时无噪音。风机采用二台L型罗茨鼓风机，能自动交替运行。单台风机运行寿命30000小时左右
