  • Waste water treatment method and equipment being able to economically treat both a waste water and an exhaust gas respectively containing fluorine and organic matter
    Patent number: 6228267
    Abstract: This waste water treatment equipment introduces granular calcium carbonate mineral 13, a calcium fluoride 14 in a floc form and a microorganism 15, which are flowing in a lower section 8, into an upper section 7 and sprinkles the same. Therefore, in the upper section 7, the granular calcium carbonate mineral 13 chemically treats fluorine in an exhaust gas, while the calcium fluoride 14 in the floc form chemically treats acid components in the exhaust gas although the effect is little. At the same time, the microorganism 15 biologically treats the organic matter in the exhaust gas. Then, the granular calcium carbonate mineral 13, the calcium fluoride 14 and the microorganism 15 that have not been utilized for exhaust gas treatment treat again the waste water in the lower section 8.
