第三節(jié)　　設備的運行方式
整個污水處理系統(tǒng)為一套兩組，兩組可以同時運行，也可以分別單獨運行，兩組之間的切換根據(jù)需要（如檢修其中一組）手動切換。正常單組運行時，一臺污水提升泵運行，單組處理能力為5m3/h，兩組同時運行時，若污水提升泵運行一臺，則單組處理水量為2.5m3/h，若污水提升泵兩臺同時運行，則由人工打開其中一組的進水閥，以實現(xiàn)兩組同時運行，此時每組處理能力為5m3/h。
整套污水處理設備的運行自動進行，值班員應定期對設備進行檢查和維護。

第四節(jié)  各設備在處理過程中的作用及系統(tǒng)的調(diào)試運行
一．各設備在處理過程中的作用：
1．進入預曝調(diào)節(jié)池的污水，首先在池內(nèi)進行預曝氣，對水質(zhì)有較好的均勻作用，同時可去除一部分污染物。
2．然后污水進入初沉池，對污水中較大顆粒，容易沉淀的懸浮物進行預沉處理，采用豎流式沉淀形式，上清液溢流進入一級接觸氧化池，底部沉泥由氣提升進入污泥池。
3．在生物接觸氧化池，通過控制各階段曝氣量使池內(nèi)保持高的溶解氧和優(yōu)良的生物菌群與有機物接觸反應環(huán)境，降解各類有機物污染。接觸氧化池分為兩段。
4．接觸氧化池出水進入二沉淀池，澄清接觸氧化池出水，形式采用豎流式沉淀池。底部污泥氣提裝置提升，一部分進入污泥池，一部分進入抽初沉池。
5．二沉池出水進入過濾池，截留去除污水中殘余的懸浮物，同時對有機物也有一定程度去除。
6．過濾池出水進入消毒池，加入氯氣，接觸消毒。
7．消毒池出水流入清水池后排放，清水池儲存一部分清水，供過濾池反沖洗。
8．污泥接納沉淀的污泥池，上清液回流入調(diào)節(jié)池，進行再處理，沉積污泥約半年清理一次。
