Experimental Study on Treatment of Leachate from Domestic Rubbish Burning Plant by Using MBR-RO System

摘要

The experiment had investigated the removal efficiency of Leachate from Domestic Rubbish Burning Plant with MBR-RO System, it's removal ratio of CODcr and ammonia nitrogen are respectivelyexceed 92% and 81% at sludge load of 0.35 kgCODcr·kg-1MLVSS·d-1, and the effluent water was conform to the Second Grade of the National Standard for Wastewater Discharge(GB 8978-1996).Simultaneity the experiment analyzed the variation and effect ofpH and metal ion in MBR, find out threeapproach of transfer and transform of metal ion. Finally the experiment had confirmed the sludge produce coefficient Y of 0.41, microbe self-oxidation ratio Kd of 0.13 and sludge residual time (SRT) of 30d.
