Disclosed is a device and method for clarifying wastewater, in which atomized steel slag balls are packed in a filtration reactor and suspended solids and organic matter contained in the wastewater are electrically attached to the slag balls and removed by passing the wastewater through the filtration reactor. The clarifier has advantages in that production of sludge is minimized because 95 % or more of suspended solids are removed and the desiccative property of the sludge is excellent, the sludge is easily treated and reused because the sludge is not mixed with other materials, slag balls are reused by removing the sludge using a back washing pump after filtration, the cost of equipment is reduced because equipment is simple, management expenses are reduced because slag balls are reused, and secondary pollution is not produced during use of the use of the clarifier. |
