<p><P>PROBLEM TO BE SOLVED: To provide a water treatment method and a water treatment system which can efficiently utilize micro-nano bubbles. <P>SOLUTION: In the water treatment system, upstream side treatment apparatuses for performing prescribed treatment by using water, for example, production facilities 11, 12 and detoxifying apparatuses 13, 14, use micro-nano bubbles, and the micro-nano bubbles are used again in wastewater treatment by a wastewater pretreatment apparatus 30 and a following wastewater treatment apparatus 10. As a result, the micro-nano bubbles are recycled, which can improve the utilization efficiency of the micro-nano bubbles. The wastewater pretreatment apparatus 30 pretreats water to be treated by microorganisms activated by the micro-nano bubbles and propagated on a material 27 filled with polyvinylidene chloride, and then introduces the pretreated water into the following wastewater treatment apparatus 10, which enables a reduction in wastewater treatment load in the following wastewater treatment apparatus 10. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
