Apparatus for treatment of waste water and/or exhaust gases containing fluorine and surface active agents

A waste water treating apparatus comprising:

• a first tank comprising:
• a first lower portion having a calcium carbonate mineral packed therein so as to be submerged in waste water introduced in the first lower portion, and aeration means for agitating the waste water through aeration;
• a first upper portion located above the first lower portion and at a level higher than the surface of the waste water introduced in the first lower portion, the first upper portion having a calcium carbonate mineral and a plastic filler which are so packed therein as to allow water penetration therethrough;
• waste water circulation means for pumping up waste water from the first lower portion to the first upper portion and spraying the pumped waste water over the first upper portion;
• and
• first exhaust gas introduction means for introducing exhaust gas into a first space between the first lower portion and the first upper portion;
• a second tank comprising:
• a second lower portion having a calcium carbonate mineral and charcoal which are packed therein so as to be submerged in the waste water introduced from the first lower portion, and aeration means for agitating the waste water through aeration;
• a second upper portion located above the second lower portion and at a level higher than the surface of the waste water introduced in the second lower portion, the second upper portion having charcoal and a plastic filler which are so packed therein as to allow water penetration therethrough;
• waste water circulation means for pumping up waste water from the second lower portion to the second upper portion and spraying the pumped waste water over the second upper portion;
• and
• second exhaust gas introduction means for introducing exhaust gas from the first tank into a second space between the second lower portion and the second upper portion.
