| Abstract: |
The internal contamination has played a significant role in eutrophication after external contamination was effectively controlled. Zeolite capping is selected to explore the release and transformation mechanisms of moderately labile organic phosphorus (MLOP) control. The result showed that the release of MLOP under weak acidic environment and weak alkaline environment are more readily achieved compared with that under neutral environments. Low temperature and light both promotes the release of MLOP. Particle sizes has no apparent effect. The release of MLOP is prohibitted by high dissolved oxygen (DO) concentration. The phosphorus released from sediments is readily absorbed by zeolite in the weak acidic or weak alkaline water body, high temperature and DO concentration. |
