    摘要: Wastewater, in the form of a colloidal solution containing microparticles, is filtrated using a second filter, having a gel film that is formed by suction on the surface of a first filter. The suction pressure in this process is made extremely weak to maintain the filtration capacity while extending intervals prior to clogging of second filter. Furthermore, the gel that becomes adsorbed onto the surface of second filter can be separated readily from the surface of second filter by stopping the suction and filtration can be continued again thereafter.

    摘要: 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.
