[0002] Wastewater treatment is to treat wastewater using physical, chemical and biological methods to purify wastewater, reduce pollution, and even recycle and reuse wastewater to make full use of water resources. Some wastewater contains a large amount of hydrochloric acid and heavy metal ions such as zinc and copper, as well as organic brighteners, which are highly toxic. Some also contain highly toxic substances that are carcinogenic, teratogenic, and mutagenic, which are extremely harmful to humans. Wastewater treatment includes high-temperature wastewater of 50°-80° generated by industrial production enterprises.

[0003] Related technologies can refer to the patent application with publication number CN217103429U, which discloses a high-temperature wastewater treatment system, including a box, wherein a first cavity and a second cavity are provided inside the box, and the lower end of the box is located outside the filter group assembly and is fixedly connected to a support leg, and a delivery pipe is fixedly connected between the filter group assembly and the box, and a control valve is arranged outside the delivery pipe, and the upper end of the box is fixedly connected to a liquid inlet pipe, a water inlet pipe and a delivery hopper. The application provides a stirring mechanism and a filter group assembly, and water is injected into the first cavity through the water inlet pipe, and the high-temperature wastewater is cooled by the water in the first cavity, and the heat in the high-temperature wastewater is absorbed to realize heat recovery and utilization. At the same time, after the wastewater is cooled, a flocculant is delivered through the delivery hopper, and at this time, the stirring mechanism starts to rotate and stir, and the flocculant condenses the impurity particles in the wastewater into flocs, thereby realizing the treatment of the wastewater, which greatly improves the practicality.

[0004] Regarding the above-mentioned related technologies, in industrial wastewater treatment, relatively pure water is first recovered by cooling, and then heated for reuse. This involves a cooling and heating process, which generates a certain amount of energy consumption and increases operating costs. Summary of the invention

9. A recycling method, applied to an energy-saving high-temperature wastewater recycling device as claimed in any one of claims 1 to 8, comprising the following steps: S1: The staff adds the industrial wastewater to be treated from the water inlet pipe (212) into the wastewater barrel (21), and first filters the large particles of impurities through the filter (211); S2: starting the filter pump (25), the filter pump (25) drives the high-temperature industrial wastewater from the wastewater cylinder (21) to flow into the filter cylinder (22), and passes through the high-temperature resistant membrane column (27) to achieve further filtration, and under the high pressure of the filter pump (25), the pure high-temperature water flows into the recovery cylinder (23); S3: The staff starts the driving motor (12), and the driving motor (12) drives the driving screw (11) to rotate, so that the two ends of the connecting pipe (24) are separated from the waste water cylinder (21) and the filter cylinder (22); S4: When the connecting pipe (24) moves away from the waste water cartridge (21) and the filter cartridge (22), the rolling wheel (156) rotates, driving the driving wheel (153) to rotate. The driving wheel (153) rotates, driving the two connecting rods (154) to move away from each other, thereby separating the two baffles (14) and opening the through hole (13) of the connecting pipe (24). S5: The staff uses a cleaning plate (32) to clean the scale inside the connecting pipe (24) caused by the high temperature; S6: Start the drive motor (12) again to complete the reset operation.
