摘要
[目的]提高小球藻去除污水中氮磷的能力。[方法]采用悬浮和固定化培养方式,研究饥饿处理及不同氮磷比对小球藻去除污水中氮磷能力的影响。[结果]悬浮培养小球藻的氮磷去除率低于固定化培养组;饥饿处理24h固定化培养小球藻的氮磷去除率较高,72h对氮磷的去除率分别达到97%、99%;降低氮磷比对悬浮培养小球藻的氨氮去除率影响不大,但可提高固定化培养小球藻的氨氮去除率。[结论]固定化培养可提高小球藻去除污水中氮磷的能力。
[ Objective ] The aim was to increase the removal ability of Cldorealla sorokiniana on N and P in wastewater. [ Method ] The effects of starvation treatment and different ratio of N to P on removal ability of C. sorokiniana on N and P in wastewater were studied through suspension and immobilization culture. [ Result] N and P removal rates of C. sorokiniana in suspension cuhuregroup were lower than those in immobilization culture group. The N and P removal rates of C. sorokiniana that was treated by starvation in immobilization culture group was higher, and the removal rates of N and P reached 97% and 99% resp. after 72 h of treatment. The decrease of the ratio of N to P had little effects on N and P removal rates of C. sorokiniana in suspension cuhuregroup, but N and P removal rates of C. sorokiniana in immobilization culture group could be increased. [ Conclusion ] Immobilization culture could increase the removal ability of C. sorokiniana on N and P in wastewater.
