The temperature sensor 6 is fixed to the bottom surface of the support plate 4 for detecting the temperature of the wastewater. The heating pipe 7 is fixed to the bottom surface of the support plate 4. The wastewater is fixed on the inner wall of the tower body 1 below the support plate 4. When the wastewater temperature is low, the wastewater is heated by the heating pipe 7. The circulation pump 8 is connected to the outlet pipe 3, and the outlet of the circulation pump 8 is connected to the return pipe 10 and the filter box 13 via the three-way valve 9. The return pipe 10 is connected to the upper part of the tower body 1 via the first solenoid valve 11.

[0024] Specific implementation steps

The algae on the algae carrier 5 treats the wastewater. The temperature sensor 6 detects the temperature of the wastewater. When the temperature is low, the heating pipe 7 is turned on to heat the wastewater. The solar panel 20 charges the energy storage box 21. At night, the circulation pump 8 draws the wastewater from the tower body 1 through the filter box 13. The filter plate 14 filters the algae into the filter chamber 15.
