摘要
采用新型 Yakult填料和中心导流式曝气方式 ,设计制作了新型生活污水净化装置 ,试验表明 ,停留时间 16 h左右 ,CODCr去除率 >80 % ,BOD5去除率 >90 % ,SS去除率 >85 % ,NH3 - N去除率 >87% 。
A kind of Yakult filing stuff and central division aeration mode were adopted for a new pattern effective domestic sewage purification system,and treament of domestic sewage by using this system has been conducted。The result showed that when retention time was 16h,removal rate of COD Cr ,BOD 5,SS and NH 3 N were 80%,90%,85% and 87% respectively,and quality of effuent could meet the GradeⅠof National Discharge Stardards.
