[0002] Some heavy metal solutions often appear in the laboratory. These heavy metal solutions play a vital role in the experimental process. However, if these heavy metal waste solutions are not handled properly, they will easily cause environmental pollution, and most of the laboratories are airtight. In a room with inconspicuous space or ventilation effect, once the heavy metal waste liquid leaks or remains, it will have a great impact on the next experimenters. If it is mild, it will affect the results of the next experiment, and if it is serious, it will endanger the personal life of the operator. Safety, causing irreversible damage, and there are many common problems in some commonly used equipment for heavy metal waste liquid, too many processes, too complicated equipment, and it cannot be used in the laboratory at all, so it cannot use

[0003] There are also some laboratory sewage processors on the market, but they cannot play their role in the face of heavy metal waste liquid. For example, Chinese utility model patent specification: CN201721349252.0 discloses a laboratory sewage treatment system. The utility model It includes a multiphase ozone catalytic tower, an ozone generator, and an acid-base neutralization tank, wherein the heterogeneous ozone catalytic tower is filled with a solid-state ozone catalyst, the ozone inlet inlet of the multiphase ozone catalytic tower and the ozone of the ozone generator The gas outlet is connected, the ozone generator pours ozone into the multi-phase ozone catalytic tower, and the sewage enters the multi-phase ozone catalytic tower through the water inlet of the multi-phase ozone catalytic tower to react with the ozone catalyst and ozone. The sewage treated by the tower reaction is discharged into the acid-base neutralization tank through the outlet of the heterogeneous ozone catalytic tower. This utility model can purify the organic matter and pollutants in the lung water, but it cannot be purified in the face of heavy metal waste liquid. It also makes it impossible to adjust the pH in the heavy metal waste liquid
