摘要
3AO-MBBR一体化生活污水处理设备设置预缺氧区,试验表明,这样能有效提高总磷的去除效率。三段进水不同占比的试验表明,最佳的进水占比为:预缺氧段10%,厌氧段40%,缺氧段50%。最佳三段进水较单点进水TN去除效率提高21.6%;TP去除效率提高30.3%,出水稳定达到《城镇污水处理厂污染物排放标准》(GB18918-2002)中的一级A标准。
The3AO-MBBR integrated living sewage treatment equipment is equipped with a pre-anoxic zone.The test shows that this can effectively improve the removal efficiency of total phosphorus.The experiment of different proportions of three-stage influent shows that the optimal influent ratio is10%in the pre-anaerobic section,40%in the anaerobic section,and50%in the anoxic section.The optimum three-stage water intake has a21.6%increase in TN removal efficiency compared with a single point;the TP removal efficiency has increased by30.3%,and the effluent has reached the Grade A standard in the"Emission Standards for Pollutants in Urban Sewage Treatment Plants"(GB18918-2002).
