There are many types of industrial wastewater with complex components. There are many treatment methods in the treatment of industrial wastewater. These are distinguished according to the different pollutants in industrial wastewater. In the treatment of some industrial wastewater, since industrial wastewater contains a large amount of calcium, magnesium and other compounds, this kind of wastewater shows hard water properties during discharge detection. When discharged into nature, the water quality is obviously converted into hard water, which has a great impact on the living environment of aquatic organisms and plants along the river, and even leads to the death of organisms.

[0036] When the present invention is used: during the process of purifying wastewater, the wastewater to be purified is added to the interior of the purification cylinder 1 through the first liquid inlet 3 and the second liquid inlet 2. The wastewater gradually flows to the bottom purification bottom box 8 through the top liquid plate 14 in the purification cylinder 1. The bottom heating plate 23 heats the wastewater inside to boil and generate steam. The steam rises and passes through the steam passage chamber 18 to preheat the wastewater flowing downward. When the wastewater is at the bottom of the purification bottom box 8, it can be continuously circulated through the reboiler 9 at the bottom to keep the wastewater at the bottom boiling and generating steam. The steam generated during the purification process enters the interior of the condensation tank 4 through the top purification top box 7. The condensed water inside the condensation tank 4 condenses the steam into purified water and is discharged through the bottom steam outlet pipe 6 to obtain purified water. The wastewater containing waste compound impurities is located in the interior of the purification bottom box 8 at the bottom. Due to the evaporation process, the concentration of waste compounds in the wastewater at the bottom increases and begins to purify. The scale inside the bottom box 8 is removed by the first drive motor driving the descaling arc frame 19 to rotate in a circular manner, the second drive motor drives the second slider 28 to adjust the vertical position, and the third drive motor drives the descaling gear 33 to rotate. The tooth surface of the descaling gear 33 is an acute-angle tooth, so it produces an extrusion effect with the scale on the inner wall of the purification bottom box 8 during rolling, and the scale is broken into small pieces. The third drive motor drives the paddle plate shaft 34 to rotate through the gear set, and the paddle plate 36 at its circumferential position rotates in sequence and lifts the descaling striking block 32. When it is separated from the top plate 38, the return spring 39 is quickly released by the compressed elastic force, so that the descaling striking block 32 hits the surface of the scale and knocks the scale off. The second slider 28 can be adjusted to descale each position inside the purification bottom box 8. After the scale is knocked down, the bottom sealing plate is opened, and the scale is discharged from the scale discharge pipe 12 through the rotating descaling arc frame 19.
