Analyze the improved microporous Carrousel oxidation ditch process about the phosephorus and nitrogen removal and influencing factors

Improved microporous Carrousel oxidation ditch is the current treatment trends, which can be modified to synchronize denitrification and phosphorous removal. In this paper, with improved microporous Carrousel oxidation ditch process as the research object, the effects of dissolved oxygen, carbon, sludge age, temperature, pH and the inverse sludge ratio of sludge on the removal of phosphorous and nitrogen were investigated, and the operating parameters of the better phosphorous and nitrogen removal were obtained. It has a certain significance in the depth-study of the phosphorous and nitrogen removal process.
