<P>PROBLEM TO BE SOLVED: To provide a method and device capable of increasing the opportunities for separating the Nemacystus decipiens from foreign materials by surely unraveling the Nemacystus. decipiens thrown in as a lump state and also surely excluding heavy foreign materials and floating materials in each of steps. <P>SOLUTION: The Nemacystus decipiens is surely unraveled and the Nemacystus decipiens and foreign materials are separated by repeating actions that the Nemacystus decipiens moves underwater through a lower hole of a partition, then collides with the lower edge of the next partition, elevates and then overflows, while the Nemacystus decipiens as the lump state is unraveled in a decomposing vessel at a highest stage, then flowed down in an inclined trough-formed alternating flowing vessel at lower stages, and repeats the lower hole underwater flows and upper end overflowing flows at the partitions installed at a predetermined interval. Also, since a method for discharging the heavy foreign materials at a bottom pocket installed at the upstream side of the partition for overflowing is at least adopted, and since the heavy foreign materials sink and go into the bottom pocket, while the Nemacystus decipiens collides with the partitions for overflowing and elevates, the heavy foreign materials can be excluded. <P>COPYRIGHT: (C)2012,JPO&INPIT |
