PURPOSE:To subject the waste water from a disinfected germination stage for seeds of angiosperms, such as rice seeds, to a pollution-free treatment in such a manner that the effluence thereof to rivers, etc., is possible. CONSTITUTION:After an oxidizing agent 3 is added to the waste water 1 from the disinfected/germination stage for the seeds of angiosperms, such as rice seeds, a flocculating agent 4 and a flocculation assistant are added thereto to flocculate the flocculating agent 4. The waste water 1 flocculated with the flocculating agent 4 is filtered and the filtrate 7 is brought into contact with granular active carbon, by which the coloring materials, insecticides and disinfectants in the waste water are removed. The pollution-free treatment of the waste water 1 is thus executed in such a manner that the effluence thereof to the rivers, etc., is possible. |
