ABSTRACT:
A wastewater treatment equipment of an embodiment of the present invention neutralizes a WTBT12by introducing the WTBT12containing fluorine components to a first treatment tank11A and by introducing an NaOH solution from a second path P2and so on. The fluorine components contained in the WTBT12is then fixed as calcium fluoride by adding calcium components to the WTBT12stored in a second treatment tank11B. Furthermore, MTBR like calcium fluoride are separated from the WTBT in a third treatment tank11C. The separated MTBR are rinsed and dewatered in a filter press17.
