摘要:

乌鲁木齐市达坂城区第二污水处置厂采取改进Carrousel 2000氧化沟工艺。针对换试时代产生的污泥上浮和出水TN、TP超标问题，经由过程检测首要水质目标和微生物镜检，连系污水处置厂的工艺运转参数，找到该问题的缘由：污泥龄太长、曝气量过年夜引发氧化沟内污泥老化上浮；没有实时弥补碱度和碳源、缺氧段DO太高致使反硝化进程没法一般进行而使脱氮结果欠安，同时引发二沉池污泥产生反硝化上浮；污泥龄太长是除磷结果欠安的首要缘由。对相干运转参数进行调剂，经由过程2个月的试运转，固然该污水厂进水量少、水质波动较年夜，但系统出水各项目标均到达《城镇污水处置厂污染物排放尺度》（GB 18918—2002）一级A尺度，对COD、TP、TN、NH_{4^{+-N、SS的去除率别离到达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, NH_{4^{+-N and SS reached 96.7%, 98.5%, 92.4%, 99.3%, 96.5%, respectively.}}
