Abstract
PURPOSE: To purify various kinds of waste water easily and efficiently by applying electric shock to waste sewage to allow the heavy metal ions contained therein to crystallize and to remove them, thence allowing other impurities to crystallize.
CONSTITUTION: Static electricity of about 500,000W1,000,000V is intermittently irradiated to waste water of plating plants or the like to allow the ionized heavy metals in the sewage to crystallize. Thence, metallic bars for recovering heavy metals are charged to stuck with the heavy metals, after which the heavy metal recovery bar are removed. Then, the 1st crystallizing chemical liquid consisting of deolite, pearlite, ferrous iron, ferric iron, aluminum sulfate, the 2nd crystallizing chemical liquid consisting of caustic soda, sodium nitrite, sodium phoshate, and the 3rd crystallizing chemical liquid of calcium carbonate are successively charged, to allow the impurities other than heavy metals to crystallize, thereby removing thses impurities. By this method, various kinds of sewage waste water are purified with good efficiency.
