Definitions

  • a method for producing the active metal salt flocculant of the present invention is provided.
  • the method for producing the active metal salt flocculant may be a method including conducting electricity using a container in which the anode side and the cathode side are partitioned by a diaphragm, and collecting the flocculant on the anode side.
  • the energization amount is preferably 5 to 60 coulombs / g.
  • this invention provides the water purification method which purifies this to-be-processed water including the process of making the active metal salt flocculent of Claim 1 contact with to-be-processed water.
  • the anode side flocculant showed an improvement in the aggregation performance, but the cathode side flocculant did not improve the aggregation performance at all.
  • the same test was performed for PSI.
  • the conditions for the electrolytic treatment were 30 minutes and 60 minutes of electrolytic treatment time as in Example 9, except that the osmotic membrane was disposed.
  • the results are shown in Table 3 below.
  • the anode side flocculant showed an improvement in aggregation performance, but the cathode side flocculant did not improve the aggregation performance at all.
  • Example 16 Public sewage first sedimentation basin drainage (Ube City, Yamaguchi Prefecture, pH of about 6.5 to 7.1) was treated in the same manner as in Example 3 using the activated PAC and activated PSI obtained in Example 14, After standing for 9 hours, the light transmission spectrum of the supernatant was measured. The results are shown in FIG. As is apparent from FIG. 15, both the PAC and PSI were electrolytically treated, and the permeability of the supernatant liquid was higher. This indicates that the substances contained in the waste water are effectively removed by the electrolytically treated flocculant.
