【正文】 ，確保經(jīng)處理后污水的排放水質(zhì)達到國家行業(yè)廢水排放的有關標準。 耗的工藝：在高程布置上作到廢水僅一次提升，以后均靠重力自流；能沉淀則不用氣浮，省去中間提升泵和回流泵的能耗；選用傳氧效率高能耗小的曝氣設施。 其次，做本設計可以使我得到很大的提高，可在不同程度上提高調(diào)查研究，查閱文獻，收集資料和正確熟練使用工具書的能力，提高理論分析、制定設計方案的能力以及設計、計算、繪圖的能力；技術經(jīng)濟分析和組織工作的能力；提高總結(jié)，撰寫設計說明書的能力等。 設計意義 設計是實現(xiàn)高等工科院校培養(yǎng)目標所不可缺少的教學環(huán)節(jié)，是教學計劃中的一個有機組成部分，是培養(yǎng)學生綜合運用所學的基礎理論、 基礎知識以及分析解決實際問題能力的重要一環(huán)。因此造紙工業(yè)的發(fā)展，導致廢水排放量逐年增加，可大量的廢水未經(jīng)處理就直接排放污染了環(huán)境，也嚴重制約了經(jīng)濟的發(fā)展。 關鍵詞： 污水處理，構筑物，投資估算，高程布置 Abstract This design is a papermaking waste water treatment plant, designed by the design specifications that the purpose and meaning, and then explain the design principles, followed by the program parison and selection, listing AB Law, SBR method,A/O method, oxidation ditch process, biofilm law. Comparison of these processes, and then find the appropriate technology, the final adoption of physicochemical + biological treatment. After the design of a flow chart of the selection process, using CAD to draw, and then all the structures are calculated to calculate the size and draw graphics. Then put all the equipment investment is estimated to be through access to information. It then describes the principles of plane and elevation layout. Finally to sum up, thanks.
