Anoxic Degradation of Dissolved COD for Enhanced Orgfanic Matter Removal in compact Chemical Treatment Plants

摘要

The potential for enhanced removal of organic matter by combined biological/chemical treatement in a compact chemical treatment plant was studied. The basic idea was that easily biodegradable dissolved organic matter, that is not removed by coagulation, might be removed rapidly anoxically. A nitrate containing coagulant was tested, where the dissolved organic matter was removed by deniftrification. An aerobic process with a standard coagulant was used as a reference. The emoval efficiency of dissolved COD was doubled from about 25
