摘要:烏魯木齊市達(dá)坂城區(qū)第二污水處理廠(chǎng)采用改良Carrousel 2000氧化溝工藝。針對(duì)調(diào)試期間發(fā)生的污泥上浮及出水TN、TP超標(biāo)問(wèn)題，通過(guò)檢測(cè)主要水質(zhì)指標(biāo)和微生物鏡檢，結(jié)合污水處理廠(chǎng)的工藝運(yùn)行參數(shù)，找到該問(wèn)題的原因：污泥齡過(guò)長(zhǎng)、曝氣量過(guò)大引起氧化溝內(nèi)污泥老化上浮；沒(méi)有及時(shí)補(bǔ)充堿度和碳源、缺氧段DO過(guò)高導(dǎo)致反硝化過(guò)程無(wú)法正常進(jìn)行而使脫氮效果不佳，同時(shí)引起二沉池污泥發(fā)生反硝化上��；污泥齡過(guò)長(zhǎng)是除磷效果不佳的主要原因。對(duì)相關(guān)運(yùn)行參數(shù)進(jìn)行調(diào)整，通過(guò)2個(gè)月的試運(yùn)行，雖然該污水廠(chǎng)進(jìn)水量少、水質(zhì)波動(dòng)較大，但系統(tǒng)出水各項(xiàng)指標(biāo)均達(dá)到《城鎮(zhèn)污水處理廠(chǎng)污染物排放標(biāo)準(zhǔn)》（GB 18918—2002）一級(jí)A標(biāo)準(zhǔn)，對(duì)COD、TP、TN、NH4+-N、SS的去除率分別達(dá)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.
