With the above scheme, when in use, the stirring mechanism 7 is started. According to the actual needs, a suitable liquid injection method is selected. The hazardous chemical waste liquid can be poured into the vertical box 2 through the liquid injection port 4. Alternatively, the peristaltic pump 8 can be started to draw the hazardous chemical waste liquid from the large-volume container through the liquid infusion hose 9. The hazardous chemical waste liquid is introduced into the vertical tank 2. After entering the vertical tank 2, the hazardous chemical waste liquid moves downward under the action of gravity and is filtered by the filter screen 5. The filtered hazardous chemical waste liquid enters the horizontal tank 3. At this time, a suitable treatment agent is injected into the horizontal tank 3 through the dosing port 6 to react chemically with the hazardous chemical waste liquid and neutralize the harmful substances in the hazardous chemical waste liquid. During this process, the hazardous chemical waste liquid is stirred by the stirring mechanism 7 to accelerate the reaction rate. After the treatment is completed, the water pump connected to the drain port 20 is started to pump out the waste liquid. This utility model realizes two liquid injection methods through the set liquid injection port 4 and peristaltic pump 8. The appropriate liquid injection method can be selected according to actual needs. When injecting liquid through the peristaltic pump 8, the hazardous chemical waste liquid only passes through the infusion hose 9 and does not come into contact with any internal components of the peristaltic pump 8, avoiding contamination and effectively preventing blockage.
