PURPOSE: An apparatus for treating tunnel effluent is provided to simply and economically remove contaminant and to prevent pollution of rive eco-system by tunnel effluent. CONSTITUTION: An apparatus for treating tunnel effluent comprises: an apparatus main body(10) with a water inflow hole(10A) and water outflow hole(10B) to inlet and discharge effluent such as washing water; and a washing water purification unit(20) for sequentially removing various contaminants contained in the washing water. The washing water purification unit comprises: a first settling tank(22) for primarily settling contaminants; a second settling tank(24) for secondarily settling contaminants; and a third settling tank(26) for discharging washing water to the water outflow hole.
