摘要:烏魯木齊市達坂城區(qū)第二污水處理廠采用改良Carrousel 2000氧化溝工藝。針對調(diào)試期間發(fā)生的污泥上浮及出水TN、TP超標問題，通過檢測主要水質(zhì)指標和微生物鏡檢，結(jié)合污水處理廠的工藝運行參數(shù)，找到該問題的原因：污泥齡過長、曝氣量過大引起氧化溝內(nèi)污泥老化上�。粵]有及時補充堿度和碳源、缺氧段DO過高導致反硝化過程無法正常進行而使脫氮效果不佳，同時引起二沉池污泥發(fā)生反硝化上浮；污泥齡過長是除磷效果不佳的主要原因。對相關(guān)運行參數(shù)進行調(diào)整，通過2個月的試運行，雖然該污水廠進水量少、水質(zhì)波動較大，但系統(tǒng)出水各項指標均達到《城鎮(zhèn)污水處理廠污染物排放標準》（GB 18918—2002）一級A標準，對COD、TP、TN、NH4+-N、SS的去除率分別達到96.7%、98.5%、92.4%、99.3%、96.5%。
Abstract:The modified Carrousel 2000 oxidation ditch process is adopted in the second sewage treatment plant in Dabancheng District, Urumqi. The causes to problems of sludge floating and effluent TN and TP exceeding standard during commissioning are found out through testing the main water quality indicators and microbiological microscopic inspections, in combination with the process operating parameters of the sewage treatment plant. They include sludge aging and floating in the oxidation ditch caused by excessive sludge age and aeration amount, the denitrification failure and accompanied sludge floating in the secondary sedimentation tank caused by high DO in anoxic section if alkalinity and carbon source are not supplemented in time, and poor dephosphorization effect caused by excessive sludge age. After two months of trial operation to adjust the relevant operating parameters, although the influent water volume was small and the water quality fluctuated greatly, the various effluent indicators could stably meet the first level A criteria of Discharge Standard of Water Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). The removal rates of COD, TP, TN, NH4+-N and SS reached 96.7%, 98.5%, 92.4%, 99.3%, 96.5%, respectively.
