针对我国污水处理厂进水碳氮比值失调、初沉池中颗粒态碳源流失严重导致生物系统脱氮除磷碳源不足的问题,开展了传统初沉池运行效果评价与活性初沉池碳源转化回收技术研究。结果表明,传统初沉池对COD的去除率达到40.49%,其中对颗粒态COD的去除率更是高达56.27%,初沉池中大量碳源的无效流失导致生物系统进水碳氮比值与碳磷比值明显降低。而在活性初沉池中试系统中,由于大量污泥在池底部长期积累,有利于水解发酵细菌的繁殖与富集。高通量测序分析结果显示,Proteobacteria (34.17%)、Bacteroidetes (22.22%), Chloroflexi (13.29%)是活性初沉池系统中的优势种群。活性初沉池系统使初沉污泥中微生物...

The insufficient carbon source for biological nitrogen and phosphorus removal in wastewater treatment plants was resulted by the imbalance in C/N ratio in influent and loss of particulate carbon source in primary sedimentation tank. In order to solve this problem, the operation of traditional primary sedimentation tank was evaluated, and the study on carbon source conversion and recovery in ac- tivated primary tank was conducted. The results showed that the removal rate of COD in traditional prima- ry sedimentation tank was 40.49% , and the rem...
