A wastewater treatment equipment of an embodiment of the present invention neutralizes a WTBT 12 by introducing the WTBT 12 containing fluorine components to a first treatment tank 11A and by introducing an NaOH solution from a second path P2 and so on. The fluorine components contained in the WTBT 12 is then fixed as calcium fluoride by adding calcium components to the WTBT 12 stored in a second treatment tank 11B. Furthermore, MTBR like calcium fluoride are separated from the WTBT in a third treatment tank 11C. The separated MTBR are rinsed and dewatered in a filter press 17.
