摘  要：
文章采用缺氧-好氧(A/O)生物膜-活性污泥复合工艺处理养猪场沼液。研究了水力停留时间(HRT)、硝化液回流比等工艺参数对处理效果的影响,分析了缺氧池、好氧池分别对污水中化学需氧量(COD)和总氮(TN)的去除情况。结果表明:考虑对氨氮(NH+4-N),COD和TN去除的影响,最佳HRT为6 d,硝化液最佳回流比为200%;硝化液回流比为200%,污泥回流比为60%时,缺氧池、好氧池对TN去除率分别为88.38%和11.62%,对COD去除率分别为81.77%和18.23%,其中缺氧池反硝化、好氧池异养菌和好氧池SND(同步硝化反硝化)对COD的去除率分别为81.77%,8.60%和9.23%。

摘  要：
The combined biofilm and activated sludge A / O process was applied in the piggery biogas slurry treatment. And the influence of operating parameters( HRT and reflux ratio of nitrification liquid) on the treatment were investigated through a lab-scale experiment. The removal rate of COD and TN by anaerobic and aeration tank were also analyzed respectively.The results showed that,considering the removal efficiency of NH+4-N,COD and TN,the optimum HRT was 6 d and the optimum reflux ratio of nitrification liquid was 200%. Under the condition of nitrification liquid reflux ratio of 200%,and sludge recycle of 60%,the removal rate of TN by anaerobic tank was 88. 38%,and that was 11. 62% by aeration tank.The removal rate of COD for anaerobic tank was 81. 77%,and that was 18. 23% for aeration tank,among which,the COD removal rates by denitrification in the anaerobic tank was 81. 77%,that was 8. 60% by heterotrophic bacteria,and 9. 23%by SND process( simultaneous nitrification and denitrification) in aeration tank.
