【正文】 性污泥污水處理技術,集進水、曝氣、沉淀、出水在一座池子中完成,常由四個或三個池子構成一組,輪流運轉,一池一池地間歇運行,故稱序批式活性污泥法。 2. 對曝氣池進行設計并計算結構尺寸,畫出其設備構造圖 設計參數(shù) 設計 污水流量 由設計資料可知,該市平均每日污水量為: 錯誤 !未找到引用源。 關鍵詞: 曝氣池 、 氧化溝工藝 、 卡魯塞爾氧化溝 、 工藝流程 內蒙古工業(yè)大學 水污染控制工程 課程設計 ABSTRACT Urban sewage is kind of sewage and waste water in the city of it by all sorts of life, collectively referred to as evil ever, industrial waste and infiltration groundwater of three parts . Contain BOD, COD, suspended solid, such as the right to remove these substances, will surface water and groundwater cause certain harm, such as black smelly phenomenon, eutrophication, directly or indirectly affect human health. The sewage BOD/COD = is the biochemical degradation. According to the water quality and quantity, the prehensive analysis of the use of the oxidation ditch, the carrousel oxidation ditch process, make city life sewage BOD, COD, SS, TN, TP removal rate were 85%, %, 90%, %, 57% and, above, the treatment effect up to the national level 2 emissions standards. This design shows the carrousel oxidation ditch process of specific design and calculation, and the specific graphics. Keywords: aeration pool, oxidation ditch process, carrousel oxidation ditch, process flow 內蒙古工業(yè)大學 水污染控制工程 課程設計 目錄 第一章 設計概述 ................................................................................................................. 1 設計內容及要求 ..................................................................................................... 1 設計內容 ...................................................................................................... 1 設計要求 ..................................................................................................... 1 設計參數(shù) ................................................................................................................ 1 設計污水流量 ............................................................................................. 1 設計原則 ........................................................................................................ 2 第二章 工藝流程的確定 ..................................................................................................... 3 污水中水質的分析 ....................................................................................... 3 工藝比選 ................................................................................................................ 3 SBR 工藝 ....................................................................................................... 3 MBR 工藝 ...................................................................................................... 4 氧化溝工藝 .................................................................................................. 4 第三章 卡魯塞爾氧化溝設計 ............................................................................................. 6 氧化溝設計參數(shù) ..........................................................
