| Abstract |
| In this paper, DAQUA System is composed with coagulating sedimentation and gravity flow fiber filtration. And application of inclination tube makes more higher sedeimentation efficiency. Three kinds of tunneling wastewater is treated for turbidity and heavy metals on DAQUA System which compared with wastewater treatment system in the actual on the field The results were revealed that Case 1. Case 2 and Case 3 each made different coagulation sedimentation effluent turbidity 0.2~9.2NTU(average 6 .45NTU), 27.0~45.0 NTU(average 34.7NTU). 67.0~121.ONTU(average 81 .4NTU) respectively. And turbidity of fiber filter effluent were 0.70~4.57NTU(average 1 .64NTU), 4.9~7.4NTU(average 6.19NTU). 14.52~42.1 5NTU(average 20.35NTU) respectively. Also sludge drained from coagulating sedimentation basin with intervals of 25-30 minutes. Final effluent was stable even if High Turbidity of raw water is entered coagulating sedimentation basin, because sludge drained shortly. Al, Fe and Mn average effluent concentration of lmg/L or more was not outflow. Tunnel wastewater treatment system is excellent, because of effluent turbidity were low twice as high in DAQUA system than the traditional tunneling wastewater treatment system. |
