摘要
井式AAOO工艺是一种集AAOO和深井曝气技术于一体的污水处理工艺。系统介绍了工艺的污泥接种驯化与反应器的启动运行状况。运行结果表明,TOC、TN、NH4+-N平均去除率分别为78.8%、60.3%、71.3%,其出水TOC、TN、NH4+-N满足《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A排放标准,TP平均去除率为74.8%,出水TP仅能达到一级B排放标准。并分析了DO、混合液回流比、污泥回流比等参数可能对系统硝化反硝化脱氮除磷功能的影响。
The welltype AAOO process is an integrated sewage treatment process combining with AAOO and deep well aeration technologies. The startingup operation of sludge inoculation and domestication and the status of its re actor are introduced systematically. The running results show that the average removing rates of TOC, TN, and NH4 N are 78.8% ,60.3% ,and 71.3% ,respectively,and the TOC,TN,NH4+N of effluent meet the requirements of first grade A of Pollutant Discharge Standard for Town Sewage Treatment Plants (GB 18918-2002). The average remov ing rate of TP is 74.8%, and the TP of effluent can only reach the first grade B discharge standard. The effects of the parameters, such as DO, mixture reflux ratio, return sludge ratio, etc. on nitritiondenitrification and dephosphoriza
