One primary filter chamber 14 bottom is paved with activated carbon adsorption bag. The arrangement order of several upper baffles 12 and lower baffles 2 is one upper baffle 12 one lower baffle 2, one upper baffle 12 one lower baffle 2, and so on, wherein one side of one upper baffle 12 is retaining wall 13. The connecting place of ozone inlet pipe 10 and device shell 1 is equipped with sealing rubber ring. Upper baffle 12 and lower baffle 2 are all equipped with lug 9, and the lug 9 of upper baffle 12 and the lug 9 of lower baffle 2 are oppositely arranged, and the lug 9 of upper baffle 12 and the lug 9 of lower baffle 2 are placed filter filler box 6. Every secondary filter chamber 8 is equipped with one filter filler box 6. The filter filler box 6 is filled with quartz sand, gravel, quartz filter material and ceramsite. The bottom of every secondary filter chamber 8 is paved with sediment guide table 3, and the sediment guide table 3 is downwardly inclined, and one end of sediment guide table 3 is connected with lower baffle 2, and the end of sediment guide table 3 connected with lower baffle 2 is lower than the other end of sediment guide table 3, and the end of sediment guide table 3 connected with lower baffle 2 is equipped with blow-off pipe 5. The last lower baffle 2 arranged in the transition chamber 17 between device shell 1 side wall, and transition chamber 17 is connected with water outlet pipe 7. Every ozone inlet pipe 10 is installed with one electromagnetic valve, and the electromagnetic valve is simultaneously opened or separately opened.
[0017] When the device for treating complex cyanide ions by ozone method is used, the wastewater is first introduced into the first filtering cavity 14 through the water inlet pipe 15. Since the baffle 13 is high, the time for the wastewater to enter the second filtering cavity 8 is prolonged, so that the wastewater stays in the first filtering cavity 14 for a long time and fully contacts with the activated carbon adsorption package 16 in the first filtering cavity 14 to adsorb the colored and odorous substances in the wastewater. With the continuous increase of the wastewater, the wastewater enters the first second filtering cavity 8 through the S-shaped channel formed by the baffle 13 and the upper baffle 12. The ozone spray gun 4 in the second filtering cavity 8 is opened, that is, the electromagnetic valve on the ozone inlet pipe 10 connected with the ozone spray gun 4 is opened. The ozone generated by the ozone generator 11 is sprayed out through the ozone inlet pipe 10 and the ozone spray gun 4. The wastewater in the first second filtering cavity 8 fully contacts with the ozone. The ozone as an oxidizing agent reacts with the cyanide ions in the wastewater. The oxidation of the ozone can convert the cyanide ions in the wastewater into non-toxic cyanate or further oxidize them into harmless substances such as nitrogen and water. The wastewater from which the cyanide ions are removed continuously moves upward and contacts with the filtering filler box 6. When passing through the filtering filler box 6, the quartz sand, gravel, quartz filter material and ceramsite and other fillers in the filtering filler box 6 perform sedimentation on the wastewater to remove the oxidized sediment and suspended matter. The removed sediment cannot pass through the filtering filler box 6 to the next second filtering cavity 8, so the sediment is deposited on the sediment guide table 3 at the bottom of the second filtering cavity 8. Since the sediment guide table 3 is downwardly inclined, the sediment is gathered at the low end of the sediment guide table 3 by the action of gravity, so as to be discharged through the blowdown pipe 5.
[0018] After passing through the first second filtering cavity 8, the wastewater successively passes through the second, third or more second filtering cavities 8. According to the actual production situation and the size of the wastewater, the number of the second filtering cavities 8 is designed. The wastewater passes through each second filtering cavity 8 to perform the reaction as in the first second filtering cavity 8 until the cyanide ions in the wastewater are removed and the sediment and suspended matter after the oxidation reaction are removed. The completely removed wastewater is buffered through the transition cavity 17 and finally discharged through the water outlet pipe 7.
[0019] The electromagnetic valves are installed on the ozone inlet pipes 10 to realize the functions of individual opening or collective opening and save energy.
[0020] From the first filtering cavity 14 to the first second filtering cavity 8 and to the last second filtering cavity 8, the liquid level is gradually lowered because the cyanide ions, suspended matter, sediment or other substances in the wastewater are removed and discharged, and the harmful garbage in the wastewater is gradually reduced.
[0021] In summary, the device for treating complex cyanide ions by ozone method uses ozone to remove cyanide ions by oxidation method, combines with the precipitation method of the secondary filtering cavity, and achieves the purpose of completely removing cyanide ions; adopts ozone as an oxidizing agent to remove cyanide ions by oxidation method, which can not only play a sterilization role, but also will not cause secondary pollution, and achieves the purpose of environmental protection; adopts the precipitate guide table to timely discharge the precipitated garbage materials for subsequent treatment work.
