南寧水塘江水質(zhì)凈化廠曝氣生物濾池工藝調(diào)試與運(yùn)行
- Title:
- Commissioning and Operation of EBAF
in Nanning Shuitangjiang Sewage Treatment Plant
摘要:- 介紹了南寧水塘江水質(zhì)凈化廠EBAF曝氣生物濾池的調(diào)試與運(yùn)行情況。調(diào)試與運(yùn)行結(jié)果表明，在低碳氮比的進(jìn)水水質(zhì)條件下，采用了更高設(shè)計(jì)濾速與負(fù)荷的EBAF曝氣生物濾池50 d即完成掛膜與馴化，同時(shí)在經(jīng)過(guò)動(dòng)態(tài)控制碳源投加量和回流比后，出水各項(xiàng)指標(biāo)均滿足《城鎮(zhèn)污水處理廠污染物排放標(biāo)準(zhǔn)》（GB 18918—2002）的一級(jí)A標(biāo)準(zhǔn)。該BAF污水廠的快速啟動(dòng)、穩(wěn)定運(yùn)行可為處理低濃度南方生活污水提供新的工藝思路和調(diào)試運(yùn)行經(jīng)驗(yàn)。
Abstract:- The commissioning and operation of EBAF biological aerated filter (BAF), which is used as the main treatment process in the Nanning Shuitangjiang Sewage Treatment Plant, are introduced. The commissioning and operation results show that under the condition of low influent C/N ratio, it took only 50 days for EBAF with higher design filtration velocity and load to complete the process of biofilm attachment and acclimation. After dynamic control of carbon source dosage and nitrate liquid return ratio, the effluent indicators can meet the first level A requirements specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002). The rapid start-up and stable operation of the BAF sewage treatment plant can provide new process ideas and commissioning experience for the treatment of low-concentration domestic sewage in southern areas.
