In this study, we used a biological contact process(BCP) to treat municipal wastewater to investigate the effect of total organic carbon (TOC) and dissolved organic carbon (DOC) removal efficiency of operating under different conditions (pH value and empty bed-contact time). Monitoring of TOC and DOC for judging microbe stability in BCP was conducted. Experimental results showed under different pH conditions were set at 6,7,8,9, TOC removal efficiency were 55%, 63%, 67% and 70%; and DOC removal efficiency were 52%, 57%, 60% and 65%. When empty bed-residence time (EBCT) were at 0.5 hour, 1 hour, 1.5 hours and 2 hours, TOC removal efficiency were 66%, 69%, 75% and 83%; and the DOC removal efficiency were 61%, 63%, 70% and 78%.The removal efficiency of TOC and DOC by BCP increased with pH increased, and removal efficiency of TOC and DOC also increased with EBCT increased.
