The Effect of Hydraulic Load Municipal Wastewater by Ceramic on Removal of COD and Ammounia-N from Using an Internal Loop Bioreactor with Honeycomb Biocarriers
Abstract：Removal of COD and ammounia-N from municipal wastewater by using an internal loop bio- reactor with ceramic honeycomb biocarriers is under study, and the article investigated the effect of hy- draulic load on the pollutants removal efficiency and characteristics. The results demonstrated that the COD removal ratio was decreased by 31.90% as hydraulic load increased from 0. 5 m3/(m2·h) to 1.5 m3/ (m2·h), but the ammonia-N removal ratio was deceased by 70.92% under the same conditions; the re- moval ratio of COD was 37.99% when hydraulic load was 1 m 3/(m2·h), with a removal load of 1.85 kg/ (m3·d) ; the removal ratio of NH3-N was 44.15%, and the volumetric load of ammonia-N was 0.83 kg/ (ma·d). And the indicative microorganism on ceramic honeycomb bioearriers displays regular changes with the increase in hydraulic load from 0.5 m3/(m2·h) to 1.5 m3/(m2· h).
