摘要： PURPOSE: To remove heavy metals and impurities thoroghly by continuously providing a crystalline heavy metal recovering bar tank by electric shock, a crystallize chemicals charging tank and a settling and storage tank in series in a purifying device for the plating waste liquid.
CONSTITUTION: The plating waste water is crystallized of heavy metals by an electric shock device 8 of a charging tank 1, and the crystals are stuck on the heavy metal recovering bars 9 of the nexg charging tank 2 and is fed to further charging tank 3. In this tank 3, three kinds of crystallizing chemical liquids are charged by three chargers 10 and the soln. is fed to a settling tank 6. Partition plates 11, 12 are provided on the trailing flow side of the tank 3 and in the tank 6 and the velocity of flow is controlled settleably by flow velocity control pipes 13, 14. Further, the bottom parts of both tanks 3, 6 form slopes, to facilitate the discharging of deposited crystalline impurities.

摘要： 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.
