STUDY OF STRUVITE PRECIPITATION IN ANAEROBIC DIGESTERS

[摘要] In this paper struvite formation and crystal forms in anaerobic digesters under differing feed types and support media have been studied. Struvite appears when the medium contains magnesium, ammonium and phosphate ions. NH4+ can be supplied from protein degradation, phosphate from bacterial exudation and Mg2+ by the supports. The precipitation of struvite has also been checked with real feeding solid wastes plus domestic sewage.
