In this paper, highrate clarifier filtration(HCF) system is operated for tunneling wastewater with coagulant. The purpose of this study is to investigate coagulant injecting position on HCF system and characteristics of heavy metals removal for tunneling wastewater treatment. The linear velocity(LV) of HCF column 1,2 were 300m/day and 150m/day, respectively. Characteristics of tunneling wastewater is neutral pH, Turbidity is experimented from 5943 to 357NTU. And optimum dosage of aluminum sulfate was 20mg/L that used this study. As a result, Coagulant injecting to HCF column 2 was more efficient for backwash cycle, because backwash cycle was 20% long over when 20mg/L of optimal alum injecting to HCF column 2. For Al, Fe and Mn reduction, the efficiency of HCF system were 95%, 98%, 98% respectively. It tend to similar with turbidity removal of HCF system.
