- Title:
- Summary of Upgrading and Reconstruction Design of Eight Wastewater Treatment Plants to Meet New Local Discharge Standard in Taihu Lake Basin
Keywords:- Taihu Lake basin; wastewater treatment plant; new local discharge standard; upgrading and reconstruction
摘要:- 為使出水水質(zhì)達到《太湖地區(qū)城鎮(zhèn)污水處理廠及重點工業(yè)行業(yè)主要水污染物排放限值》（DB 32/1072—2018）標準，對太湖流域的8座污水處理廠進行了提標改造。在分析現(xiàn)狀實際進出水水質(zhì)、主體構(gòu)筑物的參數(shù)、運行情況的基礎(chǔ)上，提出了包括預(yù)處理、生化處理、深度處理、污泥處理段的提標改造工藝技術(shù)路線，實際運行效果均穩(wěn)定良好。分析了工程直接費和增加的運行成本，并總結(jié)了不同進水構(gòu)成及建設(shè)條件下各種工藝組合的適用性以及提標改造工程在設(shè)計、建設(shè)、運行中的一些相關(guān)經(jīng)驗，可為其他類似工程提供參考。
Abstract:- Eight wastewater treatment plants in Taihu Lake basin were upgraded to make the effluent quality meet Discharge Standard of Main Water Pollutants for Municipal Wastewater Treatment Plant & Key Industries of Taihu Area (DB 32/1072-2018). Based on the analysis of the actual influent and effluent quality, parameters of the main structures and operation of the current situation, the upgrading technical route of pretreatment section, biochemical section, advanced treatment section and sludge treatment was proposed, and stable and good operational performance was obtained. The direct costs and increased operating costs of the projects were analyzed. The applicability of various process combinations under different influent composition and construction conditions and some relevant experience in the design, construction and operation of upgrading projects were summarized to provide reference for other similar projects.
