高速公路服務區(qū)污水一體化設備的組成部分

　　高速公路服務區(qū)污水一體化設備由初沉池、接觸氧化池、二沉池、消毒池及消毒裝置、污泥池、風機房、風機組成，下面是詳細的介紹。

　　(1)初沉池：設備初沉池為豎流式沉淀池，污水在沉淀池的上升流速為0.6-0.7毫米/秒，沉淀下來的污泥用空氣提至污泥池。(注：WSZ-A O.5-5m3/h不設初沉池)

　　(2)接觸氧化池：初沉后水自流至接觸池進行生化處理，接觸池分為三級，總停留時間為 1小時以上。加強型設備接觸氧化時間可達6小時，填料為新穎梯形填料。易結膜、不堵塞。填料比表面積為160m2/m3，接觸池氣水比在12:1左右。(注WSZ-A 0.5-5T/h，接觸池為二級)

　　(3)二沉池：生化后污水流到二沉池，二沉池為二只豎流式沉淀池，它們并聯(lián)運行。上升流速為O.3-0.4毫米/秒。排泥采用空氣提升至污泥池。(注WSZ—A0.5-5mT/h，污泥自流到污泥池中)

　　(4) 消毒池及消毒裝置：消毒池按規(guī)范：“TJI4—74”標準為30分鐘，若是醫(yī)院污水，消毒池可增加停留時間至1-1.5小時，采用固體氯片接觸溶解的消毒 方式，消毒裝置能根據(jù)出水量的大小不斷改變加藥量，達到多出水多加藥，少出水少加藥的目的。其它消毒裝置可另行配制。(注：如用于工業(yè)污水消毒池與消毒裝 置可以不要)

　　(5)污泥池：初沉池、二沉池的所有污泥均用空氣提至 WSZ-A的污泥池內(nèi)進行好氧消化。污泥池的清液回流至接觸氧化池內(nèi)進行再處理。消化后剩余污泥很少，一般1-2年清理一次。清理方法可采用吸糞車從污泥 池的檢查孔伸入污泥底部，進行抽吸外運即可。(WSZ-A 0.5-5T/h，污泥采用厭氧消化)

　　(6)風機房、風機：設備 WSZ-A的風機房設在消毒池的上方，進口采用雙層隔音，進風口有消聲器、風機過濾器，因此運行時無噪音。風機采用二臺L型羅茨鼓風機，能自動交替運行。單臺風機運行壽命30000小時左右
