Abstract: |
|
n this thesis, the imitated wastewater was treated using the recirculated membrane bio-reactor (RMBR). Removal effect of the various treatment methods was studied by determiningorganic pollutants of wastewater at different sludge loading, and the organic pollutants degradation kinetics model and the corresponding kinetics’ parameter was discussed. The experimental result indicated that the average removal efficiency of the system in all phase is 97.4 %, which was a high level. In the conditions of 0.22~0.27kgCOD/kgMLSS·d sludge loading, the average effluent concentration was keeping with the B standard of level 1(60mg/L)of ‘Discharge standard of pollutants for municipal wastewater treatment plant’. But as the sludge loading increasing, the average effluent concentration went beyond the standard mentioned. According to the result of this experiment, the RMBR system kinetics parameter can be concluded that Vmax was 4.21d-1,KS was 688.74mgCOD/L, and the organic pollutants removal kinetics model was [(So-Se)·Q]/(X·V)=4.21Se/(688.74+Se). |
