摘要
通过模拟生活废水处理方式,考察了几种常见的生化法处理工艺对生活废水的处理效果并加以比较和分析.分别采用曝气生物滤池、A2/O处理工艺、SBR处理工艺和MBR处理工艺对采自学校中水处理站的生活污水进行模拟处理研究.结果表明,几种方法均可以较好地处理生活污水.其中,A2/O处理工艺的COD去除率可达95.2%;MBR工艺的COD去除率可达93.3%,氨氮去除率可达65.9%;SBR工艺的COD去除率可达88.2%,氨氮去除率可达68.3%;曝气生物滤池的COD去除率可达86.7%,氨氮去除率达83.9%.实验结果表明,A2/O处理工艺的处理效果最好,而其他几种方法各具优点.
The efficiency of several common biochemical wastewater treatment technologies were investigated,compared and analyzed by mean of treating sanitary wastewater.The Biological A-erated Filter Process (BAF),Anaerobic-anoxic-oxic Process (A2/O),Sequencing Batch Reactor Activated Sludge Process (SBR),and Membrane Bio-Reactor Process (MBR)were carried out to treat living wastewater from the water treatment station in school for reclaimed water.The treat-ment results displayed that all of those methods could treat the living wastewater effectively.The removement rates of the chemical oxygen demand (COD)could reach 95.2% in A2/O,93.3% in MBR,88.2% in SBR and 86.7% in BAF;while the removement rates of ammonia nitrogen could reach 65.9% in MBR,68.3% in SBR and 83.9% in BAF.So the A2/O gained the best treatment effects,and the other methods had their own characters individually.
