摘要
采用新型填料Yakult和中心导流式曝气方式,设计制作了一体化设备对生活污水进行处理,试验表明,停留时间30h左右,COD_(Cr)去除率>85%,BOD_5去除率>90%,SS去除率>87%,NH_3-N去除率>92%,出水水质达到国家一级排放标准。
A kind of Yakult filling stuff and central division aeration mode were adopted for a new pattern effective domestic sewage purification system, and treatment of domestic sewage by using this system has been conducted. The result showed that when retention period was 30h, removal rates of CODCr, BOD5, SS and NH3-N were 85%, 90%, 87% and 92% respectively, and quality of effluent could meet the Grade I of National Discharge Standards.
