The present invention relates to a device of collecting fluoride and phosphorus, which can effectively and selectively collect fluoride and phosphorus included in wastewater by using magnetic iron oxide (MIO). The present invention, by using MIO as an absorbent, can selectively collect fluoride and phosphorus included in semiconductor wastewater by directly applying to actual wastewater without preprocessing wastewater. Additionally, due to MIO used in the process, the acidity of wastewater increases, and by removing pH buffer substances like phosphorus, the injection amount of lime, used in the existing process of wastewater, can decrease, thereby reducing sludge generating rates and increasing the efficiency of collecting fluoride and phosphorus and economic feasibility at the same time. |
