摘要
以常州丽化污水厂三期工程为考察对象,对取消混合液回流的A2/O工艺的实际运行效果进行了剖析和评价。实践表明,该工艺处理后出水水质符合GB18918-2002中一级排放标准,同时对氨氮和总磷的冲击负荷有较强的抗受能力。
Taking the third phase project of Changzhou Sewage Treatment Plant as the investigating object, analysis and evaluation for practical effect of improved A~/O process with cancelling mixed liquor reflux were done. The operational practice showed the effluent quality atter treatment was in conformity with the requirements of the first class discharge in GB 18918-2002.It was also shown that the improved system had stronge impact-proof ability against ammonia nitrogen and TP concentration.
