摘要
基于传统污水处理脱氮除磷工艺的原理设计出一体化脱氮除磷工艺.通过小试试验运行反应器并利用活性污泥2D模型对其进行设计优化.结果表明:反应器对生活污水中CODCr,NH3-N,总氮和总磷的去除率分别达到74.40%,93.15%,73.35%和33.20%.根据实验结果建立的工艺数学模型较好地模拟出了该反应器的功能,模型通过对反应器内厌氧、缺氧、好氧区的灵活组合可以实现对反应器的优化设计.该工艺占地面积小,出水能够达到国家二级排放标准,优化后能进一步提高出水水质.
An integrated nitrogen and phosphorus removal process（AmOn） was developed based on the traditional theory of wastewater nutrients treatment process.A reactor was operated in a pilot-scale study,by using activated sludge model No.2D（ASM2D）to optimize the process.The results show that the treatment efficiency of CODCr,NH3-N,TN and TP of domestic wastewater achieved by AmOn are up to 74.40%,93.15%,73.35% and 33.20% respectively.Mathematics model established based on experimental results simulated the effect of reactor well,and the combination of anaerobic/anoxic/aerobic districts smartly could accomplish design optimization.AmOn process occupies less space,and effluent could reach the second national discharge standard.After optimization the effluent quality can be further improved.
