Experiment Study on Kaidi Cyclic Active Sludge Sequence System Reactor to Nitrogen and Phosphorus Removal

The principle and treatment process of Kaidi Cyclic Active Sludge Sequence System (KDCAS) reactor were introduced; the effects of nitrogen and phosphorus removal of the reactor with different water loads were analyzed. The results indicated that with their own structural characteristics, KDCAS reactor could gain a expected results of nitrogen and phosphorus removal completely, as long as process matrix was set up properly and sludge age maintained in an appropriate range. The specific appropriate technology matrix can be optimized continually in the future productive study. Compared with UNITANK, KDCAS has the obvious advantages in nitrogen and phosphorus removal.
