A Study on Disposal of Sludge of the A/O of Denitrogenation when Enhance by Zeolite and Chemical Phosphorus Removal

Abstract:

The result showed that, after addition of a suitable content zeolite to A/O tank, the zeolite sludge had a low resistance and a high membrane flux. The heavy metals in municipal wastewater were inactivated and types of organic matter were adsorbed by the sludge containing zeolite, while sludge compressibility was decreased. It also changed the chemical composition of the sludge and added the inorganic substances such as silicon, aluminum, potassium and sodium, which obviously influenced the way the sludge could be reused.
