| 摘 要： | 研究采用聚乙烯醇（PVA）为载体的包埋固定化微生物处理低浓度氨氮絮凝余水，较短的水力停留时间（HRT）成功实现了氨氮的去除，在HRT为3h之内从地表水环境质量V类水标准以外达到了I类水标准，同时该菌对CODCr也有一定的去除能力，并系统的研究了HRT、颗粒填充率对絮凝余水处理效果的影响。

| Abstract: | The treatment of flocculation residual water with low concentration ammonia nitrogen by immobilized nitrobacteria pellets using PVA as carrier was studied. The results show that immobilized nitrobacteria pellets can remove the low concentration ammonia nitrogen effectively and rapidly, which can improve the environmental quality from class V to class I of National Water Quality Standard of Surface Water under the HRT at 3h. The pellets can also remove the CODCr The HRT has a great influence on the removal rate of ammonia nitrogen. Increasing pellets package percentage can also improve the treatment efficiency. |
